CONCEPT
Planning is the process ofquantifying the amount of time and
resources, and the size of the budgetfor the project. The output of theproject planning process is a projectplan that a project manager can use tomonitor and control the project teamsprogress.

Monitoring are the process involvesdetermining what information to collect,how, when and who will collect theinformation, analysis the info and reportingthe current progress.
Controllingis a process of comparing theactual performance with baselineperformance and discerning any deviation.
This deviation must be analyzed and suggestthe solution to bring the schedule back ontrack.

REASONS FOR PLANNING AND
CONTROLLING To know whether the project turn out to be good or
bad
To know whether it costs more than your clientthought it should be
To know if it took too long to complete To communicate information to people
To define the sequence of activities to make theoptimum use of resource
To persuade people to complete task before theydelay subsequent activities
To provide a framework for decision making in eventof change

SCHEDULE ORIENTED PLANNING
(WBS) WBS = is a hierarchical outline (map)
that identifies the products and work
elements involved in a project.
2 basic techniques -i. Bar chart/Gantt chart
ii. Network diagrams

i. BAR CHART/GANTT CHART.
A graphic representation of project
activities shown in a time-scale bar
lines with no links shown betweenactivities.
Popescu and Charoenngam, 1995
Named after their inventor HENRY L.GANTT in 1917.

THE ADVANTAGES OF GANTT
CHART/BAR CHART
Easy to prepared and understand by workers
Overall view for the project can be shown at
early stage of construction.
Work progress can be mark easily on chart.
Easy to understand and as controlling device.
Basic for calculating the work value versustime and preparing cash flow.
8/12/2019 3rd-topic
10/74
THE DISADVANTAGES OF GANTT
CHART/BAR CHART
Linkage between the activity are invisible.
No information on work flow and priority.
No certain flow/link which connected one
activity to another. Any delay will not show
effect to overall project progress.
Any changes or review on chart will not show
effect to overall project progress

CRITICAL PATH METHOD (CPM)
A logical and chronological graphic
representation of the activities and events
composing a project.
Basic component :
i. Arrow : represent logical linkages
ii. Node : represent activities and detail of
time
iii. No dummy activities

THE DISADVANTAGES OF CPM
The linkages are quite difficult tounderstand. Certain exercises and courses
are required and usually not suitable for
small & medium firms.
Difficult to understand by site workers.
Usually, be replaced by bar/Gantt chart.
Only suitable for big/huge and complex
projects.
8/12/2019 3rd-topic
21/74
TERMS AND DEFINITIONS Activity = work include time & resources
event = nodes shows the beginning and ending ofactivities
Arrow = represent activity & direction to bigger nodes
Dummy = fake activity just to explain logic in progress
Duration = time provided for each activities Earliest start/finish = earliest date activity can start
Latest start/finish = latest date activity can start
Total float = time adjustment for activity w/o
effecting the overall duration of the project TF= LSES @ LF - EF
Critical path = continuous chain of critical activitiesfrom the start to the end of the project. No floatallowed
8/12/2019 3rd-topic
22/74
RULES FOR COMPILING CPM Start and finish with a single activity
Plot activities horizontally along the paper andlink activities in logical sequence.
Determine dependency of each activity on otheractivities and link as necessary
All activities should start at the earliest timepossible
Once dependencies are complete, insert the
activity duration Examine the potential for overlap of activities,
as this will reduce overall programmed duration
8/12/2019 3rd-topic
23/74
RULES FOR CRITICAL PATH A Sequence which one activity should started
right after the completion of previous activity All activities in critical path must fully utilized
the time provided.
Must be the longest path along the process At least one critical path per every project
All activities in this path are not subject toany float
In case of any changes in critical path,modification will conclude all activities.

S-CURVE (COST AND TIME CONTROL) Basic element in EARNED VALUE(EV) technique
Typical S-curve plotted comparing budget andactual costs.
S-curves examine the progress of the projectand forecast expenditure in terms of manhours or money. This is compared with theactual expenditure as the project progresses orthe value of the work done.
All project regardless their size are plottedagainst the same parameters and characteristiccurve can be more readily seen.

BUDGETED COST OF

S-CURVE
S-curve has three significant variables that
need analyzing, time, moneyand the Sshape(known as the route)
Since the S shape or route has been foxed,
then only two variable left to be analyzed. The route is as much as a target as the final
cost. If the movement month to month is
compared then the trend can be derived.

KAWALAN MUTU DEFINISI :- Gabungan ciri-ciri bahan.
Pemasangannya dan upaya kerja ditapakyang menentukan sejauhmana mutu kerja
yang telah siap dapat memberi kepuasan
kepada pelanggan Terbahagi kpd 2 aspek :-
i. Mutu Rekabentuk
Ii. Mutu Binaan

KAWALAN MUTU MUTU REKABENTUK:- Merekabentuk dengan
mengambilkira isu-isu pemasangan, bolehbina dan keperluan utk mengkoordinasirekabentuk keseluruhan (struktur,perkhidmatan, kemasan, perabot) sebagai
satu produk MUTU BINAAN :- Pembinaan mesti menepati
kehendak rekabentuk bagi mengelakkan
mutu pembinaan berkurangan. Kakitanganpembinaan mestilah ada kemahiran, prihatindan berpengetahuan teknikal.

KAWALAN MUTU Spesifikasi : satu set dokumen bertulis
berkaitan kehendak bahan, mutu kerja danupaya kerja.
Menjelaskan secara bertulis perkara yang
tidak dijelaskan pada lukisan seperti kualitidan cara penyambungan bahan.
Sesetengan kontrak perlukan spesifikasi
sebagai syarat kontrak. Penting sebagai pengukur mutu kerja

KAWALAN MUTU 3 KATEGORI SPESIFIKASI
i. Spesifikasi bahan jenis bahan yang
diperlukan, kualiti dan ciri-ciri
ii. Spesifikasi upaya kerja kualiti buruh, hadtoleren dan kehendak keselamatan.
iii. Spesifikasi prestasi perkara berkaitan
keupayaan seperti kapasiti loji mekanikalatau elektrikal.

KAWALAN MUTU KANDUNGAN SPESIFIKASI :-
4 unsur asas dalam penulisan spesifikasi:i. Tahu apa yang dikehendaki, nyatakan denganjelas dan tanpa keraguan.
ii. Menyatakan dengan jelas. Bahasa yang mudah
difahami oleh semua orangiii. Kaedah kerja
iv. Penentuan bahan
Perkataan teknikal digunakan jika perlu. Spesifikasi
yang tidak jelas implisit akan menimbulkanpertelingkahan dan biasanya pengertian kontraktor
akan diberi keutamaan

KAWALAN MUTU Senarai Semak kaedah/ cara perlaksanaan
kerja yang mengikut spesifikasi.
Contoh senarai semak kerja konkrit:
- periksa bancuhan konkrit berasakan bancuhan danrekabentuk yang diluluskan
- Periksan peralatan ujian sebelum digunakan.
- Sediakan kiub ujian, awet & uji ikut spesifikasi
- Lakukan ujian runtuh, bulkingpasir pada batu baurdan kawal nisbah air simen

KAWALAN MUTU Contoh senarai semak kerja konkrit (samb):
- Konkrit tidak boleh dijatuhkan dari kedudukantinggi dan ke atas tetulang.
- Konkrit mesti digetar semasa dituang dan
penggetar tidak boleh kena tetulang atau kotakbentuk.
- Konkrit yang telah mengalami set permulaan tidak
boleh dibancuh semula dan mesti dibuang.
- Setelah konkrit mengalami set akhir, ia hendaklah
diawet dengan melembapkan permukaan terbuka.

KAWALAN MUTUUjian Kesesuaian
- ujian atas bahan/komponen bagi pastikan iaboleh digunakan seperti yang ditetapkan
- Dilakukan di tapak atau makmal
- 2 kaedah ujian kesesuaian bagi bahan
i. Bahan yang dihasilkan pengeluar dan diuji dikilang
(persampelan) dan diberi pengesahan piawaian
sirim bagi mengesahkan mutu bahan tersebut.Cth :pintu tahan kebakaran/simen
ii. Bahan yang perlu diuji ditapak seperti konkrit.

KAWALAN MUTUUjian Prestasi
- Dilakukan di tapak atau makmal- Untuk kawal mutu bahan yang tidak boleh
dilakukan dengan ujian kesesuaian
- Ujian kiub, ujian beban & sambungan paipUjian Kefungsian
- Ujian bagi pastikan sistem/produk berfungsi seperti
dalam objektif rekabentuk asal.
- Ujian ini biasanya dilakukan di tapak
- Contoh ujian ke atas pam atau air-cond
