Tutorial 4 - schedule



This tutorial is create a schedule and perform a network analysis (AON) based on our WBS.

Our project estimated completion time is 909days [(365 days x 3) - (52days x 3) - 30holiday]
project start on 24 May 2010
earliset finish time = 904 days (14/5/2013)
Float time = 5 days
Tutorial 3 (2)

Our ROI (Return of Investment)

Estimated total cost: $25, 419, 364
Estimated total claim interim payment from client: $37,119, 960

We assume that there has a 5% defect of the gain, so final gain is 95% of total interim payment from client.

ROI = ($35,263,962 - $25,419,364)/$25,419,364
= 38.7%

Tutorial 3 - Costing





What is cost estimation for main contractor of construction?? Normally, for a contractor, a bid estimate submitted to the owner either for competitive bidding or negotiation consists of direct construction cost including filed supervision, plus a markup to cover general overhead and profits. The direct cost of construction for bid estimates is usually derived from a combination of following approaches.
- Subcontractor quotations
- Quantity takeoffs
- Construction procedures

In this Tutorial must apply the WBS concept into costing. Based on our WBS as Tutorial 2, the main elements are people (labors/staffs), materials, machinery and equipments. Hence, we use these items as parameters for the cost estimates.

In addition details of the costing must include fixed costs, variable cost and others costs.
Fixed costs - staff's salary, subcontractor's quotation, materials costs
Variable costs - labors' salary, machinery and equipments cost
Others costs - foreigner working permit levy, hire ausitor inspect site, contigency cost

Resources requirement &Machinery and equipment















Poject Management - Tutorial 1

1.0 Project Objectives

- To provide comfortable house
- To attract mid level income buyer
- To increase organization profit
- To improve organization service

- To complete contruction within our budget
- To complete the project in 3 years


2.0 Scoping of the project:


2.1 Estimated duration
Construction time takes about 3 years to complete.


2.2 Estimated cost
Total estimated cost is SGD 27,131,000.00.


2.3 Responsibility matrix
On the matrix, the different roles appear as columns, with the deliverables listed as rows. If wish to know who the people are that are filling each role, its can place the actual names on the matrix. Then, use the intersecting points to describe each role's (or person's) responsibility for each deliverable. A simple matrix as follows.




The letters are interpreted as follows:
· A means that the person (or role) approves the deliverable.
· R means that the person (or role) reviews the deliverable.
· C means that the person (or role) creates the deliverable. (Usually there is only one person who is responsible for creating a deliverable, although many people may provide input.)
· (Other codes could be I -- Provides input and N -- Is notified when a deliverable is complete. It can create other codes for the project.)


In the table above, the Project Definition document is created by the project manager; reviewed by the project team and approved by the project sponsor, project director and the steering committee. The Business Requirements are created by the project team; reviewed by the project manager and the project director; and approved by the project sponsor and steering committee.

The purpose of the matrix is to gain clarity and agreement on who does what, so that it can define the columns with as much detail as makes sense. For instance, in the above example, Project Team could have been broken into the specific people that make up the project team, with each person given their own column. It could then specify the actual individual responsible for the creation of the Business Requirements.

After the matrix is completed, it should be circulated for approval so that everyone understands and agrees to their roles and responsibility. If this is done early enough, it can be included in the Project Definition (charter). If it is done a little later it can be created as a standalone project management deliverable.


2.4 Current issues

Steel price in market is increased, indirectly affect project cost.
Adopt flexibility in selecting the layout scheme for every units sold, it means uncertain layout for unsold units that caused some difficulty for constrcution work (Archi & structure)
In line with the Economic Strategies Committee (ESC)’s recommendation to shift towards productivity-drive economic growth, Building & Construction Authority (BCA) have to raise the quality of our local and foreign workforce. To do so, the Ministry of Manpower (MOM) will introduce a tiered levy framework to encourage the upgrading and retention of the more experienced and higher skilled foreign workers as well as to raise foreign workers’ levies. To enhance productivity, MOM will also cut the Man-Year Entitlements (MYEs) quota progressively.
