Civil Engineering Page 1 CE3605 Construction Contracts, Business, and Sustainability Assignment 2 As the project manager for a Civil & Building Construction firm, you have been tasked to manage a building contract recently awarded to your organisation. The plan and elevation drawings of this project are as shown in Figure 1 below. The house is to be constructed on a strip foundation and its external walls are to be built of bricks. The roof shall be tiled on timber-trussed rafters with roof gutters and rainwater pipes incorporated. The Internal partitions shall be in plasterboards on timber studs and rendered with mortar, finished with emulsion paint. Figure 1: Plan and elevation view of the building project Other relevant information on this project includes: 1. Construction methods shall be mainly by direct labour with some minor use of equipment. Labour is paid on daily basis and includes: (i) Unskilled labourers (L) paid at the rate of £80 per day per person; (ii) Tradesmen (T) paid at the rate of £100 per day per person; 2. A list of the main activities involved in the project construction, as defined in the Bill of Quantities (BOQs), together with their immediate predecessors are as indicated in Table 1. Table 1 also shows their estimated durations and theirCivil Engineering Page 2 budgeted resources based on the contractor’s prices quoted for various items in the BOQs. 3. The conditions of the contract allow for interim measurements (valuation of works) to be made on weekly basis. o The payment of any certified amount to the contractor shall not only be subject to 5% retention, but will also be made one week later. o Half of the retention shall be included in the final certificate on practical completion and the other half is to be released 6 weeks after practical completion. 4. The company shall add a contribution mark-up of 25% to the estimated cost of all the items in the BOQs to cover for profit and overheads. 5. Addressing sustainability at all phases of this project is of particular interest to the client. Submission Requirements (a) Develop a programme in the form of critical path network for managing the construction of this project and hence determine the project completion date and its critical path, assuming unlimited use of the resources. The programme should be in the precedence diagrammatic format, showing the sequence of operation, the earliest and latest times and the total float for each activity. [30 %] (b) Based on the resource requirements given, draw total manpower histogram (chart) for this project and, produce a resource smoothing charts that would ensure efficient use of resources with minimal or no peaks and troughs. [15 %] (c) Prepare a cash flow forecast diagram for this project, and discuss the cost flowrequirements to be provided by your organisation to ensure the successful funding of the project till completion. [35 %] (d) Discuss three (3) key relevant sustainability measures that can be adopted by management to ensure satisfactory delivery of the project. [15 %] (e) Your report must be presented neatly and should be of acceptable presentation standard. All relevant details and analyses followed should also be included. Clearly indicate the sources of any information you use and provide references accordingly using the referencing system recommended by the school. [5%]Civil Engineering Page 3 Note: 1.
