ROLES OF SUPERVISION

SITE SUPERVISOR Principal contractor can supervise a site themselves or delegate safety responsibililties to a supervisor. Know the site safety plan and make sure everyone sticks to it. Ensure trades are inducted before they start work. Always know who is working on your site and conduct regular inspections. Ensure contractors are doing their part with site rules and Safe WorkMethod Statements(SWMS) Find and fix hazards or, if you cant, promptly raise the issue to the next level. Ensure the site is ready for each trade before they arrive. Talk regularly with contractors and their crews about safety on site.

MAIN CONTRACTOR Responsible for the safety of your employees and contractors Know what crew is up to at all times. Ensure your crew is inducted and obeys site rules. Pay specific attention to the training and supervision of young or inexperienced workers. Use a SWMS for high risk construction work, and make sure it suits the site. Let the site supervisor know when your crew is on site. Find and fix hazards or, if you cant, report them to the site supervisor. Talk regularly with your crew, site supervisor and other contractors about safety on site.

WORK PROGRAM CHART Work program is an important element in any Construction project. It is a document where it will become a guide for those involve in the project on when to start and complete a particular project component or task. In actual fact work program is contractor plan on when to start the project and how we plan to complete the hole project. This process is a planning technique for repetitive work. The essential procedure for this scheduling technique is to allocate the resources needed for each step or operation, so the following activities are not delayed and the result can be obtained. With a large list of activities, each activity is then linked to previous and subsequent activities, specifying that each activity has at least another one that must be completed prior to starting the preceding one. The calendar days are established and activities are assigned with an early date, first date that an activity can start; late start, specifying the last possible date that this activity must be started to avoid delays in the overall construction process; early finish, the earlier date that the proposed activity will be completed; and the late finish, that is the last date the activity must be completed without affecting the start of the next one, and subsequently affecting the entire construction schedule.

DAILY RECORDMost common way of using daily record that person who fills it keeps it to himself. This ensures that person remembers events and factors which took place on the site. It also can be used as a evidence.

Example of daily record Weather Activities Materials Manpower Agreements and offers Documents

SITE MEETING During the construction stage the contract administrator (sometimes referred to in different forms of contract as the 'architect / contract administrator', 'project manager', 'engineer' or 'employer's agent') holds regular (often monthly) construction progress meetings attended by the contractor and if necessary members of the consultant team introduce contractors to each other and to the project control group familiarise the contractors with the site, this includes their break area, access, parking and out-of-bounds areas explain all health and safety requirements, including those particular to the school and students explain the project brief including expected milestones discuss reporting lines and who to talk to if issues arise advise administrative processes eg, invoicing, recordkeeping explain special school requirements eg, dealing with student interaction advise the process if any toxic building materials are encountered during construction eg, asbestos respond to issues and questions.

BAR CHART

WHAT IS BAR CHART?A bar chart or bar graph is a chart with rectangular bars with lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column bar chart.A bar graph is a chart that uses either horizontal or vertical bars to show comparisons among categories. One axis of the chart shows the specific categories being compared, and the other axis represents a discrete value. Some bar graphs present bars clustered in groups of more than one (grouped bar graphs), and others show the bars divided into subparts to show cumulative effect (stacked bar graphs).

GANTT CHART

Roles of site supervisor for consultant based on gantt chart Avoid Completion Confusion Keep Everyone on the Same Page Understand Task Relationships Effectively Allocate Resources Get a Handle on the Future

BENEFITS OF USE GANTT CHART They are very easy to read and comprehend They identify the project network coupled with its schedule baseline They allow for updating and project control They are useful for identifying resource needs and assigning resources to tasks They are easy to create

CRITICAL PATH METHOD

The critical path method (CPM) is an algorithm for scheduling a set of project activities.It is an important tool for effective project management. The essential technique for using CPM is to construct a model of the project that includes : A list of all activities required to complete the project (typically categorized within a work breakdown structure), The time (duration) that each activity will take to complete, The dependencies between the activities. Logical end points such as milestones or deliverable items.

DEFECT LISTThe first few construction defects in the list involve what is referred to as the Building Envelope, they relate to the components that define the shape structure and exterior protection elements that comprise the building.

1. Windows- Improper lapping is sometimes blamed for leaks as well as failed or improperly installed flashings- particularly at sill ends.2. Roofs- Badly installed flashings faulty installation of roof membrane are some of the causes of leaking roofs.3. Improper Drainage- Reversed slope, i.e. towards building can create conditions that can be expensive to repair.4. Concrete Slabs- slabs that are not properly cured or dont have adequate compressive strength are issues that are difficult and costly to repair.5. Decks- Failure of water barriers and or improper installation is the most common issue here. Damage can be difficult to detect until it is well advanced.

6. Electrical- a multitude of difficult to detect issues can present here including double tapping at connections. Failures can cause fires, which sometimes take years to occur, making tracing the cause difficult.7. Plumbing- a myriad of problems from leaking pipes to improper or ineffective slope of drains.8. Below Grade- Buried slabs can create conditions where water is introduced into the interior due to.9. Insulation- Improperly installed or missing insulation often results in issues such as poor cooling or heating of the interior spaces.10. HVAC- Improper location and installation of dampers, vents and ducting can result in ineffective heating or cooling and possibly even life threatening situations in the case of flammability issues.

LIABILITY PERIOD (DLP)Defect Liability Period (DLP) is a common feature in all the standard form of construction contracts in Malaysia, i.e. PAM 98/JKR PWD 203/IEM/CIDB 2000. During the DLP, the Contractor is obliged andliable to rectify defects that appear between the period the Certificate of Practical Completion (CPC) is issued and the expiry of the DLP.

SITE REPORTThe following log items are processed like a check list so that no important entries are forgotten:- Weather- Construction site occupation- Day's work of each company- Performance status (text, photos)- Defects (text, photos)- Delays- Obstructions- (Partial) acceptance processes - Instructions given to companies- Additional comment- Important building operations- Tests and measurements- Unusual incidents- Deliveries of building materials- Planned deliveries

CONCLUSION

Site supervisors are found in a range of industries, from manufacturing to property management. They responsible for managing staff members, ensuring that procedures are followed, setting performance targets and communicating with managers. The primary responsibilities of a supervisor are to make sure that work is completed on the site, to ensure compliance with company procedures and to create performance metrics.
