Abstract The development of human resources in construction industry has become a
necessity over the last few decades; the un-development of human resources is
a major factor inhibiting effective planning and implementation of
construction projects in Gaza Strip. The employment of craftsmen in
construction is characterized by unsuitability; the construction worker is hired
on a project with the objectives of working him out of job by completing the
project.
The construction industry faces many challenges. Many of these challenges
arise from the need to keep a skilled and competitive craft workforce,
challenges such as changing demographic characteristics, changes in the
economics and technology, difficulties in maintaining a skilled work force,
rapid changes in the economy, social changes and organization technological
environment changes.
The main objective of this study is to study the causes of construction workers
dissatisfaction in the construction sectors, identification of the factors that
affect the development of the human resources in the Gaza Strip construction
industry and development of a model for the human resources development in
construction sector.
The results point to that the main causes of construction workers
dissatisfaction are: lack of possibilities for better future in the construction
sector, lack of future skills improvement and training by the employer, lack of
job security, lack of necessary incentives, working hours per day exceeding 8
hours and delay in salary payment
The results indicated show that the main factors for human resources
development in the construction industry are: skills development of manpower
to increase performance, availability of appropriate training programs that can
V
be implemented and measured, improve communication skills between project
parties, political and security stability in the region for investment in
construction and availability of training institutions to develop manpower
skills. The finding of the study concluded the important of construction
workforce characteristics, statistics and future trends. It also aims to the
perceptions of the construction workers and employers. The findings of the
study are of immense importance to policy makers in their mission to maintain
skilled and adequate construction workforce able to face the future demand of
this industry.
The study recommends gathering statistical information on the construction
workforce available in the construction sector, conducting training and
education programs for the project mangers, site engineers and workforce to
improve their skills. In addition to this a conceptual model for the
development of the human resources in the construction industry in Gaza Strip
was designed.

Chapter 1
Background of the Palestinian construction sector
This chapter contains information on the construction industry in Gaza Strip
West Bank, but with focus on Gaza Strip in addition to data on the
construction sector, and workforce, related to the subject of the thesis. Also, it
contains the importance of this research, problem statement, and the
objectives.
1.1 Palestinian workforce in construction sector:
The Palestinian economy unlike other economies lacks national strategic
control and self monitoring system, because it has never been under full
Palestinian control. The economical growth in Palestine lies with Palestinian
private sector. Small scale, single owners and family enterprises are dominant.
Large enterprises are still very limited in number. The private sector
industrialists have been accustomed to profiting under difficult circumstances
(PIEFZA, 2004). The construction industry is vital for the Palestinian
economy and necessary infrastructure development. Construction sector relies
on imports of raw materials. But due to closure, such materials could not be
imported, causing delays in construction projects, jobless and high daily
sectorial losses (PCHR, 1995).
The construction sector is one of the key economic sectors and is the main
force motivating the Palestinian national economy. Upon the establishment of
the Palestinian National Authority and the assuming of its powers over the
Palestinian territories in 1994, the construction sector has witnessed
noticeable expansionional activities. This has resulted in the recovery of the
construction contracting profession and subsidiary industries, encouraged the
investment of the Palestinian expatriates capital in the local construction
sector, and contributed to the creation of jobs for thousands of Palestinians.
Therefore, the construction sector has occupied the foremost position among
the rest of sectors, mainly in the attraction of investments and creation of new
jobs (PCU, 2006). Construction is one of the most important sectors in the
assimilation of labor force throughout Palestinian cities and towns. Prior to
the Israeli re-occupation of the Palestinian territories on September 28, 2000,
construction sector used to employ an average of 22.3% of Palestinian labor
force volume. However, the sector now employs 10.8% of the labor force
volume only, thus constituting a decrease in the labor force volume as a direct
consequence of the Israeli forces occupation (PCBS, 2005).
In 1992, the Palestinian labor force amounted to 350, 000. By 1999 it had
risen to more than 630, 000. This increase had the effect of reversing, in per
capita terms, any economic growth that took place before the present Intifada
(Winkler, 2002). By 1993, 120, 000 Palestinians were commuting to Israel for
work. Their earnings made up a major part of the income in the West Bank
and Gaza in that year, however, Israel imposed the closure, in effect firing all
of this labor force. Closure has been in effect, with varying severity, ever since
(WAC, 2004).
When first imposed in March 1993, the closure had a negative effect on Israel
which experienced a sudden shortage of labor force in construction and
agriculture. In the spirit of globalization, Israel solved the problem by
replacing the Palestinians with migrant workers, who proved to be cheaper.
This occurred within a few years. Israeli contractors gained cheap labor, while
the political establishment continued its policy of containing the Palestinians
within cantons. These measures have been part of the ongoing attempt to
suppress the Palestinian peoples desire for self-determination (WAC, 2004).
In September 1993 the first of the Oslo Accords was signed. They proved to
be unbalanced. While Israel enjoyed years of strong economic growth (1993-
2000), the Territories grew only in poverty. The Paris Protocol, signed by
Israel and the PLO on April 29, 1994, did not allow an independent economic
entity (PER, 1994).
The Oslo Accords created the Palestinian Authority (PA). During its existence
(effectively ended by Israel in May 2002), the Palestinian economy remained
dependent on Israel. As long as Palestine is not free to establish economic
relations, trading independently of Israel, the obligations of Israel as the
occupying power will remain (WAC, 2004). During the Oslo years, in the
areas under the control of the PA, there was a considerable expansion of the
public sector. This did not, however, create an independent basis for industry,
such as could supply work for the increasing number of job seekers. The
dependence on Israel continued (WAC, 2004)
The Palestinian business sector likewise continued to depend on Israel for
energy, communications, raw materials, and its ability to export. This reality
has not changed in the last three and a half years of Intifada. The outbreak of
the second Intifada led to a further deterioration in the territories. Israel used
harsher means of economic oppression in its attempt to break the spirit of the
people. A report by the UN Special Commission for Palestine (UNSCO)
pointed out the dangers: The Palestinian economy is mired in a deep crisis,
with unemployment levels rising significantly over the first half of 2002.
Particularly hard hit are the West Bank cities and towns, which the Israeli
military has placed under lengthy curfews. On days with curfew, the estimated
unemployment rate reached 63. 3 %. Income losses now total US$ 3.3 billion
since October 2000. Poverty levels continue to increase at alarming rates,
reaching 70 % in the Gaza Strip (UN, 2002)
1.2 Construction industry in Palestine:
The construction industry in Gaza Strip has played a key role in the countrys
socio-economic development, creating the physical facilities and infrastructure
which have made possible the nations remarkable progress. Following effort
to improve upon it, the industry is relatively advanced. However, it continues
to use labor-intensive techniques (MAS, 2002).
The construction sector is considered one of the important sectors of industries
for the economy of Gaza Strip and plays a major role in the infrastructure
facilities development. It mainly relies on the local workforce and the raw
materials which imported from outside the country through Israel exit points.
This caused a severe shortage of raw materials and increase in the cost of these
materials for users. The construction industry suffered great losses in term of
quality, cost, and delay in handling projects due the policy of Israeli closure of
the exit points (PCHR, 1995).
1.2.1 Employment of construction analysis: The construction and housing is a driving force in the Palestinian economy.
The value of its contribution rose from $410 million in 1994 to $483 million in
1999 in the WBGS. Between 1994-1999, $6000 millions were invested in the
construction industry, comprising housing units, public and commercial
buildings, and infrastructure facilities. Investment in buildings rose from $906
millions in 1994 to $1018 millions in 1999 in the WBGS. The employment in
the construction sector dropped from 47,400 workers in the third quarter of
2000 to 25,120 in the second quarter of 2002 in the West Bank. And in Gaza
Strip the number of workers was down from 15,700 to 4000 during the same
period. In term of percentage there was a 47% drop in the West Bank
construction employment and a 75% drop in the Gaza Strip (MAS, 2002).
Table 1.1 shows the employment distribution by sector. This Table illustrates
that in 1999 there was 22.1 % of work force in Gaza Strip and West Bank
were working in the construction industry, which represent the highest
percentage in the period between 1995 to 2006. In that year (1999) there was
stability in the political situation and higher investment in the construction
industry. After Israeli measures against the Palestinians people which took
place in the year 2000, the percentage of construction employment declined to
13.1 % in 2003 (PCBS, 2004)

1.2.2 Contribution of construction industry to the Palestinian economy
GDP:
It's estimated in the year 2000 the construction industry contributed around
300.3 million dollars of total GDP of the Palestinian economy. And this figure
started to decline to reach 188.8 million dollars in the year 2004. This
occurred due to the political unrest in the region and the harsh Israeli measures
against the Palestinian territories which started on October, 2000. Table1.2
presents the GDP by economic activity in the Palestinian territory at constant
prices for the year 2000 to 2004 (PCBS, 2005).

1.2.3 Percentage contribution to GDP by construction sector
It's estimated that the construction industry, contributes around 10 % to 12%
of total GDP of the Palestinian economy for the period between 1995 to 1999.
But for the last four years the construction contribution to the Palestinian
economy is declined to reached around (5 % to 7 %) of total GDP of the
Palestinian economy. This occurred due to the political instability and Israeli
measures taken against the Palestinians. Table1.3 presents the GDP by
economic activity in the Palestinian territory at constant prices for the year
2000 to 2004 (PCBS, 2005).

1.2.4 Main economic indicators for construction activity
Table 1.4 illustrates the main economic indicators for the construction
contractor's activities (formal sector, 1999-2003). The Table shows the
number of construction contractors for years 2000 were 430 registered active
construction contractors and the number started to decline to reach 348 in
2003 which means that around 20% of construction contractors were off work.
The number of persons engaged with these construction contractors was 5,864
for 2000 and this figure declined in 2003 to reach 3693 persons which means
about 37% of construction workers lost their jobs in 2003. The compensation
of the employees working with construction contractors were 32.2 million
dollars in 2000 and the figure declined to 14.7 millions in 2003 by other word
there was 54.3 % loss of income for construction employees who work for the
construction contractors. The main reason behind this deterioration in the
construction sector is the political disturbance and the closures of the
Palestinian territories by Israel (PCBS, 2005).

1.2.5 Contracting companies in Palestine:
There are 587 contracting companies in Palestine according to the Ministry of
Public works and Housing (MPWH) , where 64% (374) contraction companies
in West bank, and 36 % (213) in Gaza Strip (Alquds, 2005). The Palestinian
contraction Union classified members by skill, competency and administrative
and financial proficiency. The classification of the contraction companies is
performed by the MPWH. Qualification is monitored on continuous basis and
requires a complete updates of construction company capital, equipment
values, maximum value of projects, minimum value of projects, experience
value of executed projects, and office. The considered update duration is two
years. And companies must submit vigorous prequalification process (PCU,
2006).
1.2.6 Palestinian contraction union (PCU)
The Palestinian Contractors Union, a registry industry association established
in 1994, is an economic, social and professional association which enjoys
independent legal, financial and administrative status. PCU advocates and
defends the highest standards of professionalism for construction industry. In
meeting the needs for construction value and integrity, the PCU performs a
number of valuable services for its members such as classification, training
program, firm's level assistance, information services, dispute resolution, and
public program (PCU, 2006).
1.2.7 Classification of Contractors
Classification of contractors is the most significant of the services provided by
the PCU. Such process shall protect the contractors against illegitimate
competition and maintain their rights. In addition, classification of contractors
shall organize the construction contracting profession and set right the
selection of contractors with the qualifications required for construction
projects (PCU, 2006).
1.2.8 Classification Categories
According to Ministry of Public Works and Housing there are over 587
contracting companies in Palestine, 374 contracting companies in West bank
and 213 in Gaza Strip .The total number of first, second and third contractor
categories is 135 contracting companies, 27 companies of first class (A) , 42
companies of first class (B), 36 of second class and 30 of third class (Alquds,
2005). Table 1.5 illustrates the condition and requirements of contractors'
classification (PCU, 1994).

1.3 Problem statement:
In recent years, considerable attention has been directed towards issues
connected with the recruitment and employment of labor within construction
industry. Concern has been directed variously towards both the structure of
employment that characterized the industry, and the implications of
employment patterns for the performance of industry. The human resources
factor involved in the construction industry is significant and of high
importance as it plays a major rule in the success or failure of the construction
projects and it affects the three implementation phases factor (Time, quality,
cost).
The manpower in the construction industry in Palestine is not given attention
neither from the construction companies nor from the concerned governmental
authorities. Studying the availability of skilled workers, training, quality,
mode of payment and future strategies to develop the construction workforce
is essential and justified for success of the projects. The number of workers
taking career in the construction industry is on the rise and this industry
involves around 16 % of total work force in different Palestinian industrial
sectors (PCBS, 2004).
Human resources development in construction which is investigated in this
research focuses on the development of the human factor which involves in
the construction, this involves assessing and improving individual
performance, managing career, and providing organization management
development.
Given the stated concern with manpower issues in construction, it is perhaps
surprising to find that little systematic attention has been directed towards
identifying and documenting the range of recruitment and selecting strategies
that are adopted within the industry. Such focus as there is tends to be upon
the structure of employment within the industry as a whole, with less
consideration directed towards the mechanism of selection the recruitment at
site level. In other words, relatively little is known about how individual
contractors formulate their demands for labor, and how this is then put into
effect in terms of the procedures adopted for recruitment. Moreover, with a
limited number of exceptions, the focus of investigation has tended to be more
aggregate (firm/ industry) level analysis. It would therefore seem likely that a
fuller understanding of the labor process in construction may be gleaned from
a more detailed investigation of the patterns of selection and recruitment
adopted at an operational level.
This study is an attempt to study the current situation of human resource in
construction industry in Gaza Strip. The workforce in construction industry is
the vital part in the construction sector and it costs nearly 30% to 50% of total
cost of the construction projects. There is less awareness among the
construction organizations and construction engineers about the role of the
workforce in construction industry. In this research, an attempt is carried out
to put bases for the development of the human resources in construction
sector.
The hypotheses considered in this research are to find out the relationship
between the characteristics of the research sample and the factors that affect
the human resources in construction industry and to see the relationship
among the groups of human resources development factors.
1.4 Objectives:
The main objectives of the study are the following:
1. Assessment of the existing manpower with regards to:
Identification of age distribution, job experience, salaries,
performance, education level, and determining the
dissatisfaction factors for construction workers.
2. Assessment of external factors which affect the construction
workers.
3. Establishment of training and stuff development policy for
construction employees.
4. Forecasting the future labor demand and supply policies.
5. Testing the first major null hypothesis which states that there is
no significant difference in the mean value of the causes of the
construction workers dissatisfaction due to marital state, age,
experience, and length of service at level 0.05.
6. Testing the second major null hypothesis which states that, there
is no significant difference in the mean value of the groups of the
human resources development factors in construction industry
due to the occupation, experience, projects value, organization
average annual value, organization experience.
7. Testing the third major null hypothesis which states that there is
a relationship between external factors group, training and staff
development policy group, and labor supply and demand group.
8. Develop a conceptual model for the development of the human
resources in the construction industry in Gaza Strip.
9. Providing practical suggestion and recommendations for the
development of the human resources factor in the construction
industry.
Chapter 2
Human resources issues in construction industry
This chapter deals with definitions, recruitment, skills, technology,
construction productivity, training, and manpower development of human
resources in construction industry. Also this chapter discusses deferent issues
which concern the development of human resources in construction.
2.1 Introduction
An issue of fundamental importance is that the development of human
resources became evident over the last few decades; the un-development of
human resources is a major factor inhibiting effective planning and
implementation of construction projects in developing countries. The problem
is due to the major deficiencies at the managerial level, a situation aggravated
by a dearth of managerial competence in society at large (Imbert 1990). The
employment of craftsmen in construction is characterized by unsuitability; the
construction worker is hired on a project with the objectives of working him
out of job by completing the project (Uwakweh, et al.1991).
The construction industry faces many challenges. Many of these challenges
arise from the need to keep a skilled and competitive craft workforce,
challenges such as changing demographic characteristics, changes in the
economics and technology, difficulties in maintaining a skilled work force,
rapid changes in the economy, social changes and organization technological
environment changes (Jayawarane and Gunawardena, 1998).
The reasons for the under development of human resources in developing
countries are many and various, some are historical, or geographical. But what
appears important reason however is the lack of perception on the part of
planners and an executor of economics polices, they seldom recognize the role
of skilled technical manpower in development (Imbert 1990).
The construction industry in most countries is characterized by an area of
labor pools, this allows for movement of workers among contractors and
between the different construction branches. Contractors are in need for
workers to hire from the area of labor pools and return workers to the pool
when they are no longer needed (Uwakweh, et al. 1990).
The construction challenges can be addressed by a deep understanding of the
structure and characteristics of the skilled work force, the economical impact
on the construction industry, understanding the social and the surrounding
environment of the construction industry, and the strategies used for
construction organizations and human resources (Jayawarane and
Gunawardena, 1998).
2.2 Concept of human resource management HRM
Over the last three decades, there has been widespread discussion about the
concept of human resource management. The term, in everyday use, has been
a replacement for personal management, but its meaning and significance has
been the subject of wider academic debate. The distinctive features of HRM
have been identified as its holistic approach to personal policies and its
integrative, strategic approach to personal issues within the context of business
planning and development (Druker et al. 1995)
Human resources management can be defined as" the practices and polices
you need to carry out the people or personal aspects of your management job.
This includes recruiting, screening, training, rewarding and appraising, these
concepts are too important for managers, the following are some mistakes that
take place in a company or organization that may not use the human resources
management tools (Dessler, 2000).
a. Hiring the wrong person.
b. High turnover.
c. Workers not performing what expected from them.
d. Higher idle time.
e. Unfair payment.
f. Training requirement.
2.3 Human recourses management and success factor of constructibility
The availability of labor is a major consideration in investment decision
(Agapiou et al. 1995 a), the data available on the subject of labor force is great
but many of these data are incomprehensible to companies and large projects
are located in areas where insufficient labor to satisfy the demands generated.
(Agapiou et al 1995 b). Construction industry around the world is
characterized by unstable level of activities and fragmented nature of
operation and susceptibility to economic nature (Thomas et al. 2001). Many
construction workers are hired on project bases and made redundant on project
completion (Jayawarane and Gunawardena, 1998).
The availability of skilled labor is a major consideration in investment
decision, and the level of the demand for the skilled workers is affected by the
cyclical nature of the construction work load (Agapiou et al. 1995 a).
Construction is in a period of rapid cultural change accompanied by the
introduction of new technologies and new ways of organizing construction
activities. The construction industry will continue to face increased
competition in search for eligible recruits to train accordingly. (Agapiou et al
1995 b). Therefore reliable labor force data and proper investment plans are
pre-requisites to such accurate labor models (Jayawarane and Gunawardena,
1998).
The engineering-construction is a service industry. People are keys to its
success; selection of the appropriate team is a critical management task. Once
a team is selected, the most effective role of management is to nature the
growth of the team by showing visible support to the achievers. One form of
support that appeared important is the management willingness to accept the
risk taken by project team. The teams technical capabilities, compatibility of
individuals, sense of ownership of the constructibility are factors of success of
project. The following Tables 2.1 and 2.2 show the description of
constructibility factors (Eldin, 1998).

2.4 External issues affecting human resources management in
construction
The construction industry exists in a turbulent and complex environment
which makes planning for future extremely difficult. Nevertheless, it is
precisely such future planning upon which the effective management of
human resources depends. Demographic, technological and social values
changes have important effects on HRM and each of these constitutes a part of
the organization's external environment (economic, political and technological
environment influences (Langford et al. 1994).
2.4.1 Workforce demography
A) Demographics include the age profile of construction workers, education,
training, remuneration, gender and migratory work pattern (Jayawarane and
Gunawardena, 1998). Strategic managers in business and industrial
communities have begun, in the last 15 years, to become more aware of the
need to appreciate the influence of demographic changes on their activities
(Langford et al. 1994).
The causes of the skills shortage in the construction industry are
attributed to number of factors
1. The demographic decline in the young people available to enter the labor
market, which has increased competition for few entrants to labor pool,
(Drucker et al. 1996).
2. The changing nature of construction markets and the demand for skills,
which has attributed to a reduction in construction operatives with many
traditional skills (Drucker et al. 1996).
3. The introduction of new technologies, requiring new skills, and in some
instance a higher level of new entrant training and continual
development of existing labor pool (Agapiou, 1995 a and CITB, 1991).
4. The cyclical nature of construction market, which historically has
resulted in extreme fluctuation in construction output, employment and
training levels (Drucker et al. 1996).
5. The growth of self-employment, the use of specialist labor, and the
decline in construction training and training resources (Agapiou, 1995 b).
The traditional response to shortage of any type of skilled labor is to increase
remuneration. However and up-turn in demand will not be satisfied only by
this strategy, this because labor losses are contributed by retirement,
movement to other industries, reduction in new entrant intake level, and the
fact that many operatives drawn from the ranks of unemployment may not
possess the necessary skills (Mackenzie, et al. 2000). The primary effects of
these factors is that the construction employers poach labor from each other,
leading to inflation rises in the cost of construction, this in turn reduces
demand, which temporarily contributes to reducing the labor shortage
(Agapiou, 1995).
B) Young people in construction
The future and current supply of construction skilled labor mainly depends on
the recruitment of young people, and some upgrading of semi-skilled
operatives to skilled jobs. The increasing number of young people available to
enter employment has for the construction industry, particularly in the
searching for eligible recruits to train for future skills required. As a result of
the increased number of young people staying off at school, construction
employers are finding no difficulties to recruit apprentices. (Agapiou, 1995 a).
C) Adult workers
Alternatives to young recruits are adult recruits; they are more enthusiastic to
work than young workers, especially when they are fully trained (Dessler,
2000).
Agaipou, (1995) Stated that the craft workers who moved out of construction
industry to take more stable and good payment and better job condition
represent a potential pool of labor.
2.4.2 Technological changes
Technology is the key to element in the construction industry, to a certain
extent the level and sophistication of the technology employed by an
organization will depend upon two factors that have to be successful; these
factors are managerial philosophy and employee expectations and needs
(Langford, 1994). Increasing technological sophistication of both construction
products and processes mean that the need for technical, knowledge-based
skills is growing, introducing new technologies create problems at interfaces
between new and existing systems. This occurs when people lack the skills to
work alongside those using technologies (Gann, 1998).
The technological change in the construction, industry is restricted to changes
or improvement in material specifications, and product ranges. Agaipou,
(1995) Stressed on that, new technology that appears gives arise to the need
for a combination of skills from traditional separate construction trades, this
includes the development of a prefabricated system.
2.5 Labor recruitment in construction
In recent years, considerable attention has been directed towards issues
connected to the recruitment and employment of labor within the construction
industry. Concern has been directed variously toward both the structure of
employment that characterized the industry, and the implications of
employment patterns for performance of the industry. To a large extent the
identification of the selection and recruitment of site labor as an issue
warranting more detailed attention, has derived from concern about the
implications of both the excessive casual nature of employment in
construction, and the maintenance of apparently less formalize process of
labor recruitment than encountered in other industries (Ford et al. 1983).
2.5.1 Factors in labor recruitment
The following factors are taken as bases to investigate the labor recruitment
(Bresnen, et al. 1986):
1. Site manager has a high influence over selection criteria.
2. Head office is not involved in recruitment.
3. Head office approval for recruits is required.
4. Site manager usually does not take up references.
5. Site manager is willing / able to offer higher earnings.
6. Site manager prefers to know workers.
7. Site manager prefers to recruit people that can be vouched for.
8. Site manager would not recruit unknown workers.
9. Site manager prefers experienced workers.
10. Site managers would be wary of recruiting workers without formal
qualifications.
11. Site managers have found it difficult to recruit labor.
2.5.2 Informality in recruitment
In particular, the spatial dispersion of construction sites, and the relatively
temporary and transient nature of much construction work mark out
construction as potentially quite distinct from other industries in terms of
procedures and criteria adopted for labor recruitment (Bresnen, et al. 1986). In
construction industry, the usual way of selecting staff for employment is by
interviewing them, following the submission of application form, or CV
(Langford, 1994). While the scope of recruitment undertaken by main
contractors on the sites emphasize upon less bureaucratic channels and
relatively informal processes (Bresnen, et al.1986).
The formal ways of selecting and recruiting is used in developed countries. In
construction, the most used method of employment depends on casualization,
and it is the only employment system used in the industry that being used
world wide this because most construction companies employ a core of
professional and technicians as well as tradespersons and laborers. There is
also often a core of direct employees playing a supporting role, including
administrative and clerical staff, in addition there are self employed
tradespersons and laborers and subcontracted trade-persons (Oferi and Debrah
1998).
Given the stated concern with manpower issues in construction, it is perhaps
surprising to find that little systematic attention has been directed towards
identifying and documenting the range of recruitment and selecting strategies
that are adopted within the industry. Such focus tends to be upon the structure
of employment within the industry as a whole, with less consideration directed
towards the mechanism of selection the recruitment at site level. In other
words, relatively little is known about how individual contractors formulate
their demands for labor, and how this is then put into effect in terms of the
procedures adopted for recruitment. Moreover, with a limited number of
exceptions, the focus of investigation has tended to be more aggregate (firm/
industry) level analysis. While this emphasis provides important materials for
debates up on the degree of casualism within the industry as a whole, the
question as to what firms do in respect of a particular set of requirements faced
at the operational level (site or project) remains unanswered (Bresnen, et
al.1986).
2.5.3 Selection process
The selection process itself appeared to be one over which site management
exercises a considerable influence degree of autonomy and discretion
(Dessler, 2000). Most site managers, 72% reported a high level of influence
over selection criteria. However, there did appear to be a good deal of
variation in the extent of head office involvement (Bresnen, et al. 1986).
2.6 Labor demand
Whenever you are recruiting, it is important to know what is required, formal
job description can be so vague or out of date that they are useless. It could be
beneficial both to construction organizations to generate their own by asking
present and, if possible previous job incumbents to write their own
descriptions (Langford, 1994). In understanding the process of selection and
recruitment adopted by main contractors, one must take full account of the
broad factors that inform the whole approach to recruitment. The relatively
informal procedures adopted and the high level of local site control reflects the
importance of relatively short-term operational requirements as the prime
factor in the formulation of labor demand. Furthermore, these have to be set in
context of a (pre-site) planning process which is geared to the assessment of
labor requirements primarily for tendering process (Bresnen 1986).
2.7 Construction Labor Demand by Skills
Figure 2.1 presents a framework for forecasting construction labor demand by
skills, in construction industry. The frame proposed by (Uwakweh and
Maloney, 1991) and the elements of the frame is discussed as follow:
2.7.1 Technological alternatives
Technology refers to the systematic application and utilization of either
scientific or organized knowledge to accomplish a task. Thus, technological
alternatives exist in and industry if there is more than one way to perform a
certain activity. In developing countries, technological alternatives may be
influenced by governmental regulations, for example government may require
contractors to bid for projects using labor-intensive methods even though
capital-intensive techniques may increase productivity and lower the cost
production (Uwakweh and Maloney, 1991). There is a close relationship
between availability of skilled labor and choice of technology, decision to
adopt new technologies have sometimes been made because of lack of
traditional craft skills (Gann and Senker 1998).

2.7.2 Relationships between forecasted supply and demand
The relationships that exist between forecasting supply and demand for labor
will lead to varying technological decisions. For example, in surplus situation
labor-intensive techniques may be appropriate, and vice versa, data on
construction labor forecasts may be available from the Ministry of Labor or
may be obtained by a survey of major construction firms (Uwakweh and
Maloney, 1991).
2.7.3 Historical relationship of expenditure to labor demand
Construction product expenditure by labor demand may be obtained by the use
of coefficients that express the man-hour requirements by skill for any desired
standard. Determining the expenditures on construction to products and skills
required over time will provide the planners with man-hour estimate of labor
demand by skill for a certain dollar value of construction product. The data
required for estimation of expenditure to labor demand by skill may be
obtained from contractors or architects that data may obtained by analysis of
major projects (Uwakweh and Maloney, 1991).
2.7.4 Decide on desired construction technology
The decision on the desired construction technology is influenced by the
economic objectives for the planning horizon, the technology available and
relationship between forecasted supply and demand for construction labor, one
of the economic objectives of the planning horizon may be to increase labor
productivity. Because of this the contractors, may use new pieces of
equipment in their operations.
2.7.5 Seasonality parameters
The construction industry is a seasonal industry. The seasonality may be a
result of weather or patterns of contract awarded. For example, employment
activity follows changes in weather during rainy seasons; there may not be
type of highway construction where in dry season, most highway project
underway.

2.8.1 Population data for a region
Changes in the nature of a population have far-reaching effects on an
economy. A nation population influences the size of the labor supply because
future manpower is dependent on the number of persons of working age. A
study of the population is therefore a necessary starting point for forecasting
the future manpower supply. Population growth results from the infraction of
the number of births, the amount of immigration and emigration, and the
number of deaths. An analysis of these factors can generally provide a basis
for forecasting the size of future population.
2.8.2 Participation rate and required data
The participation rate is that population of the population age 18 years or more
who are active in the labor force. The participation rate in the labor force is
influenced by individual's decisions to seek work or to withdraw from the
labor force. The data required for calculating the participation rate are the
number of persons in the labor force.
2.8.3 Estimate size of the labor force
The regional labor force is defined as those persons from the region over age
of 18 years who are employed or are looking for work.
2.8.4 Estimated enrolment in training programs
A good proportion of the regional population may not possess adequate skills.
Because of this lack of skills, training programs may be necessary for the
development of an adequate regional labor force supply.
2.8.5 Estimating number of persons possessing a specific set of skills
The number of persons possessing specific skills is estimated from an analysis
of the regional labor force and training statistics. From this estimated of the
number of persons possessing special skills available during the planning
period can be determined. The estimate will reflect the diversity of skills
possessed in the regional labor force for the planning horizon.
2.8.6 Seasonality parameters
The supply of workers in the construction industry varies with the seasons.
2.9 Human resources information system
The casual nature of employment in the construction industry makes planning
human assets difficult. Human resources information systems (HRIS) offer a
means of coping with these problems through improvements to the reliability,
accuracy and accessibility of the HR information. A HRIS is a computerized
system used for acquiring, storing, manipulating, analyzing, retrieving and
distributing pertinent information regarding the human resources of the
organization (Thomas, et al 2001). An example of HRIS function module see

2.10Assignment and allocation of multiskilling workforce
2.10.1 Multiskilled workforce
Multiskilling is a work force strategy that used to reduce indirect labor costs,
improve productivity and reduce turnover. Its defined as worker who posses
a reasonable range of skills that allow them to engage in more than one work
discipline (Gomar, et al., 2002, Burleson, 1998). Because craft boundaries are
blurred using multiskilling, a multiskilling workforce can be organized in such
away, that workers are employed for longer duration at the site while the
project hiring requirement are reduced (Burleson, 1998).
The poor image of construction industry makes it difficult to attract new
workers and the lack of opportunities for training and career growth leads to
high turnover rates (BRT, 1997). This trend will not be soon changed. To be
competitive in construction industry, it is necessary to consider strategies to
balance the competitiveness in construction industry (Gomar et al. 2002).
Field studies have also indicated that multiskilling may benefit workers in
term of benefits such as longer employment duration, better qualifications
resulting in increased employment opportunities and increase job satisfaction
(Burleson, 1998). A worker may be selected to participate in any activity in
which workers may be related to different work activities, rather than being
replaced by an additional workers success of multiskilling greatly relies on the
formans ability to assign workers to appropriate tasks and compose crew
efficiency (Gomar et al. 2002).
But the strategy of multiskilling may affect the level of standards and quality
in construction work activities, we may not expect the workers to show similar
standard in different work activities and the level of performance may change,
and the quality too. Multiskilling may not be comfortable to workers, and
gives them the feeling of un-comfortability in performing the daily activities,
thats happen due to change in the daily workers assignment, higher workload,
and the workers may not possess the same standard of performance in the
different work activities ( Burleson et al. 1998). To counter such setback in
this strategy, good incentives (Direct incentives and indirect incentives) should
be offered to workers (Dessler, 2000).
2.10.2 Multiskilling in construction
Construction industry is a very labor intensive industry and the labor cost in
projects accounts for (30-50 %) of total project costs. The low productivity in
the labor performance is behind the higher cost of labors in construction
industry (Adrian, 1997). Multiskilling in construction is a labor technique that
addresses many causes of low productivity. With multiskilling in construction
workers may expect to have longer employment durations, continuity of job
assignments, and reduction of idle time. Potential product of multiskilling is
increased efficiency, increased safety, lower personal costs and lower total
labor costs (Gomar et al. 2002). Some people believe that multiskilling also
improves productivity due to benefits stated above. For example, an average
increase of 20 % due to multiskilling was estimated by six companies that
were surveyed in one study. It is reasonable to be skeptical of these estimates,
however for instance, the companies in this study have not accurately
measured increased in productivity, partly because the varied nature of each
project makes an exact value difficult to obtain. Also the shift to multiskilled
workforce strategy has not been typically a perfectly documented one
(Burleson et al. 1998).
2.11 Alternative multiskilling strategies
Four multiskilling labor strategies were defined by (Burleson et al. 1998).
These strategies were developed in cooperation with researchers and industry
patterns to reflect a spectrum of multiskilling possibilities. And they are as
follow:
2.11.1 Dualskill labor strategies
The dualskill was developed as and extension of the traditional wave theory of
project scheduling " as a schedule is developed, the goal is to get the crews to
come to the job, work continuously with maximum productivity until their
work is completed and then move on the next job". Form this description; it is
clear that current labor strategies attempt to minimize disruptions while
working within existing craft structures. The demand-driven dualskill strategy
extends the wave theory to identify craft combinations with complimentary
work loads so that workers arrive on the project remain longer by working on
multiple tasks before demobilizing (Burleson et al. 1998).
2.11.2 Four skills labor strategy
The four skills strategy states that, craft workers could be grouped into four
general craft classifications that reflect the major phases of project and
perhaps, also reflect varying skill complexity and craft similarities as well.
The four skills craft groupings include civil/structural workers, general support
workers, mechanical workers, and electrical workers. All craft workers are
assigned to one of those four grouping (Burleson et al. 1998).
2.11.3 Four skills-helpers labor strategy
The four skills-helpers is a modification to the craft classification defined in
the four labor strategy. Each original craft group was composed of workers
from three skill levels: helper, journeyman, and foreman (Burleson et al.
1998).
2.11.4 Theoretical maximum labor strategy
The final strategy in this contest is theoretical maximum labor strategy. This
strategy assumes that there is only one craft classification for construction
industry "construction workers". In this theory, all construction workers are
fully multiskilled and could be used flexibly across any task in the project.
Varying levels of skill acquisition are still recognized within this multiskilled
craft grouping. Functionally, this labor strategy identifies a maximum to the
benefits of multiskill craft utilization that are quantified (Burleson et al. 1998).
2.12 Factors behind low-productivity in construction sites
2.12.1 De-motivation of workers
De-motivation of workers is considered one of the primary reasons behind
labor inefficiencies, de-motivation include, discontinuity of job assignment
and feeling of purposelessness due to idle time on the job site. Both of these
de-motivators negatively impact the attitude of the workers and act to lower
overall productivity (Gomar et al. 2002).
2.12.2 Workers short employment duration
Many of construction workers face problems resulting from short employment
duration, frequent layoffs and periods of unemployment between jobs because
of the flow of work and manpower fluctuation experiences in construction
industry productivity (Gomar et al. 2002).
(Zakeri et al., 1996) Stated the following causes behind the low
productivity of construction workers
1. Lack of material.
2. Weather and site condition.
3. Equipment breakdown.
4. Drawing/specification/ change orders.
5. Lack of proper tools and equipment.
6. Inspection delay.
7. Absenteeism.
8. Safety and accident.
9. Improper plan of work.
10. Repeating of work.
11. Changing crew size turnover.
12. Interference at work.
13. Poor communications.
(Kaming et al., 1997) Studied the factor influencing the craft's
productivity in Indonesia, and they are as follow:
1. Characteristics of the construction project.
2. Type of the employer.
3. Length of stay with employer.
4. Length of stay with similar type of projects.
5. Age of the craftsmen.
6. Experience of the craftsmen.
7. Experience by type of buildings.
8. Type of training / education background.
9. Method of construction.
10. Site management.
11. Working environment.
12. Level of payment.
13. Unproductive time of a typical work per week (Internal delay, lack of
skills, waiting and relaxation, or supervision).
14. Material unavailability. (On-site transportation, excessive paper work
for request, improper material storage, or/and inadequate planning).
15. Rework due to, poor instruction, design changes, poor workmanship,
or/and complex specification.
As stated earlier, multiskilling is a labor strategy that solves many of the
causes of low productivity of workers. With this strategy workers will have
longer duration period on work, continuity of work assignment, decrease the
idle time, also improve workers payment and incentives, good safety
conditions, and decrease the total labor cost (Burleson et al. 1998).
2.13 Manpower development and planning:
The aims of manpower planning are to maintain satisfactory human resources
levels both in quantity and quality, to maximize the performance and well-
being of existing human resources and to anticipate potential human resources
surpluses/deficits and identify associated problems (Thomas, et al. 2001). The
key stages are summarized. These comprise of:
2.13.1 Assessment of existing manpower (Stage 1)
a. Age distribution.
b. Job experience.
c. Length of service.
d. Salary/wage pattern.
e. Performance.
f. Education level.
g. Training.

2.14 Human resources training and education
The nature of the human resources problem and its pervasive effects indicate
the need for extraordinary action to upgrade managerial and technical skills,
broaden their range and increase their totality. Training and education are,
consequently needed at all levels and across a wide spectrum of technical
disciplines. Considerable research is also required. The training term in
construction industry can be defined as Training refers to the methods used to
give new or present employees the skills they need to perform their jobs
(Dessler, 2000). Investment in training, equipment and research and
development by UK construction firms has fallen in since the late 1970s. In
spite of this, labor productivity rates appear to have grown by more than 5 %
between 1981 and 1995. This was a faster rate of growth than the average for
the economy as a whole. Although the data are problematic in term of
reliability and comparability, labor productivity levels in the UK compare well
internationally and recently have been higher than France, Germany and Japan
(Gann and Senker, 1998).
2.14.1 Education and training
The craft training should be given equal importance are often inhibited by
inadequate financial resources and paucity of technical teachers, the latter is
itself one of the consequences of underdevelopment of human resources.
Because of their inability to achieve the objective of improving skills with
their own resources, many developing countries have resources to external aid,
thus personnel may be trained in developed countries, specialists from those
countries may conduct training locally and/or joint venture may set up (Impert,
1990). Above all efficient on-site production and organization are tasks for
qualified workers. They work to a great extent autonomously and responsibly,
so the cost for instruction, supervision and quality control can be restricted.
Moreover, qualified construction workers are not just trained in one particular
area; they also have a certain basic knowledge of other construction trade
without incurring high transfer costs every time (Syben, 1998).
Although self-employment and subcontracting provide a flexible structure in
terms of response to short-term market fluctuations, they are not conductive to
longer-term investment for culture growth by firms. Fluctuation in output,
smaller size and specialization of projects makes it difficult for individual firm
to plan labor requirement. Moreover, frequently short-term competitive
pressures lead to poaching of skilled labor and act as a future disincentive to
training, for these reasons, few construction firms develop human resources
plans and most take insufficient interest in integrating training into their
corporate strategies (Gann and Senker, 1998).
Vocational training and employee development are issues that are of key
concern to personal practitioners at present, as traditional forms of training are
in decline, but there is little evidence of new training initiatives having
achieved a widespread impact for the core work force. In part these issues
have been given renewed attention as skill shortages have accompanied the
growth in unemployment and self-employment (Agapiou, 1995 b).
Training is one of the areas in which line management responsibility has
increased significantly over the last few years. But with the extent of self-
employment and the decentralization of decisions on training expenditure,
there is a question mark over the ability of companies to make a significant
impact on skill shortage (Druker, 1996). Indeed, what is required more than
ever before is a highly trained cadre of people who are alive to the needs and
realities. Training and education have a dimension beyond that of direct
improvement of the level and spread of skills. These skills must themselves be
so imparted as to create an intrinsic capacity for generation, and utilization of
technology (Impert, 1990).
Construction employers and their workforce need to be aware of regional
differences in the availability of trainee labor when considering alternatives
recruitment strategies. The availability of certain labor groups in any region
depends on different regional factors, including staying-on rates,
unemployment rates, and the concentration of ethnic minorities as a
percentage of all employment. These factors taken together with forecast of
output levels provide and indication of what would be appropriate training
strategies. (Agapiou, 1995 a)
So, we question whether the outputs of current training programs are sufficient
to meet current and future needs. Is the skill structure sufficiently adaptable to
support innovation? To what extent should training be broadly based? To what
extent should it be specific to particular trades? Do structure sand institutional
rigidities hinder training de
