Daffodil International University B. Sc. in Civil Engineering Midterm Examination, Summer - 2026 Course Code: CE 401 Course Title: Project Planning and Construction Management Section: A, B Level-Term: 4-2 Teacher's Initial: SAB Full Marks: 25 Date: July 4, 2026 Time: 1.5 Hours Note: There are four sets of questions in total. Answer all of them. Right hand margin indicates full marks. Assume any reasonable missing value. 1. (a) Explain the basic principle of the following construction contracts: [CO1, C2] [03] i) Lump sum contract, ii) Unit price contract, iii) Cost plus contract (b) Explain the basic principle of the following project delivery methods: [CO1, C3] C2/ i) Design-bid-build, ii) Design-build, iii) Construction Management at Risk 2. Construct the Bar Chart for the following table: [CO2, C3] [03] Activity | Description | Duration (weeks) A | Site Selection and Survey | 4 B | Design | 6 C | Preparation of Drawings | 3 D | Preparation of Specifications and Tender Documents | 2 E | Tendering Process | 4 F | Selection of Contractor | 1 G | Award of Work Order | 1 Table:1 Finalizations of Designs and work order for a Building project The activity breakdown for the project is as follows: - A and B can be started together - C cannot start until A is completed - D can only start after both A and B are completed - E cannot start until both C and D are completed - F succeeds E - G starts after the completion of F 3. (a) The following figure shows the network for a construction project, with [06] expected time estimate of each activity marked. Using PERT method, compute- [CO3, C3] i) Critical path and its standard deviation ii) Probability of completion of project in 52 days iii) Time duration that will provide 78% probability of its completion in time [Figure: Network diagram with nodes 1 to 10 and durations marked on arrows] Standard Normal Distribution Table (b) The following figure shows the network for a construction project, with [06] expected time estimate of each activity marked. Using CPM method, compute- [CO3, C3] i) The event time of each activity ii) Activity time (EST, EFT, LFT, LST) iii) Total float of each activity and critical path [Figure: Network diagram Figure-2 with nodes 1 to 10 and durations marked on arrows] 4. Describe the following shortcomings/limitations of bar charts and their [04] remedial measures with diagrams. [CO5, C2] i) Lack of degree of details ii) Review of project progress
