1 Faculty of the Built Environment BLDG 2023: Construction Planning Assignment (30%) Due Date: Friday, 31 May 2017, 4.30 pm Submit to: The Student Centre, Faculty of the BE DESCRIPTION This brief sets out what is required to be done by each team and should be read in conjunction with the BLDG2023 study materials uploaded to the Moodle. This is a group assignment, and 3-5 students are allowed in a group. Your group should approach the assignment according to the following guidelines and complete all the tasks: 1. Study the plans/drawings provided in Appendix 1. As the detailed design is not available, when necessary, you will need to make assumptions – compliant with the information given in the Appendix 1. 2. Prepare a Work Breakdown Structure. The WBS should reflect your construction strategy and should show the different stages of construction. 3. Define the activity list in a way that the project can be controlled easily. The total number of activities shouldn’t exceed 120. 4. Determine the dependencies and sequence of activities. 5. Determine the duration of each activity. The detailed design is not available so activity duration should be estimated. 6. List the sequence/dependencies of the activities and the duration of the activities in an appropriate, tabular format. This list would be used for data entry in a planning package like MS Project or Primavera. 7. Use the information you constructed in tasks 2 to 6 to generate bar chart and critical path network by using MS Project or Primavera or any other planning software. 8. Predict the project completion date, based on the constraints given in this project. 9. Based on the information provided in Appendix 1, do the resource levelling for “Site Work” work package. Draw resource histogram and calculate efficiency measures like RIC and RUF before and after levelling. SUBMISSION REQUIREMENT 1. A title page includes all the subject details, and group members. A statement that signed by all the group members that you have shared the work equally and are willing to accept the same mark for this assessment item. 2. The results of tasks 1 to 9. The bar chart and critical path network that you develop using the software is preferred to be on A3 paper. 2 ASSUMPTIONS 1. Start date is 2 June 2017. Total duration is 300 working days. 2. Working times: a. Monday to Saturday are working days. b. Show Sundays, Public Holidays and Rostered Days Off (RDOs) as non-working days. c. Show Christmas shutdown period from 23 December 2017 to 8 January 2018. d. Assume that work on the site is permitted between Monday to Saturday between 7 am to 7 pm. e. Allow 7 days for “Handover, practical completion and demobilization”. KEY AREAS OF ASSESSMENT 1. Assessment Criteria You will be assessed as follows: a. Structure and Flow of the report: 20% b. Ability to create an appropriate WBS and activity list, milestones, and sequencing: (25%) c. Ability to prepare a practical schedule including estimating activity durations, identifying critical path, and float times using a software package: (30%) d. Ability to prepare a resource-loaded schedule and levelling over-allocation: (15%) e. Writing including formatting, English, punctuation, and referencing: (10%) 2. Formatting Assume that the program once complete will be presented to your client for review. The schedule when submitted must be formatted and printed in A3 being no more than 1 page wide (and multiple pages long) and bound for professional presentation. Ensure that you utilize the features of MS Project to ensure proper page layout including titles, page numbers, labelling activity bars, etc. The submission shouldn’t be more than 40 pages in size. 3. Team Submissions Teams must develop and submit their own team assignments; teams must not share information with one another as teams are in competition with one another. Please keep your own separate copies as the submitted assignments are not generally returned to teams. 4. Scheduling and Sequencing Special attention should be made in relation to how activities are sequenced and scheduled. If you use “Finish-Start” relationships with all activities then the total project duration will exceed 300 days and hence the project will fail. Aim to show leads and lags between activities as much as possible to compress the total project duration. 3 APPENDIX 1- The Sample Project The project is construction of combination plant-office-warehouse for a small industrial firm. A plan of the entire complex is shown in Figure 1 and a perspective of the building and exterior elevations are shown in Figure 2. Figure 3 shows a site plan section of the electrical service and sewer. The floor plan for the plant is shown in Figure 4, the office in Figure 5, and the warehouse in Figure 6. Exterior elevation views of the building are shown in Figure 2, and interior sections are shown in Figure 7 and 8.

Castin-place piles will be moved to about 10 meter for both plant and warehouse foundations. The office building will be on spread footings. A well is needed as no water is available; a 200-cubic meter water tower will be needed. Sewage and power trunk lines are 600 meter away. Power connections will be overhead pole line, up to 60 meter from the building; from this point in, the power line will run underground. The sewer will pass under part of the power line. The structure of both plant and warehouse structures are made of steel with high-tensile-strength bolted connections. An overhead crane way runs the length of the building; the warehouse will have a monorail. The roof system will be bar joists and precast concrete planks covered with 20year built-up roofing. The siding of both buildings will be insulated metal panels with insulated 10 glass upper panels to admit light. Both buildings will have concrete floor slabs, which will be poured on compacted sand. After plant and warehouse shells construction, interior partitions (offices, bathrooms, etc.) will be made of concrete block. Integrated HVAC along with fluorescent light fixtures will be hung on the interior ceilings; the loading docks will be made of reinforced concrete. The railroad siding must be brought in from a spur line 2 km away. The office building will be made of precast concrete structure with masonry walls. The roof will be made of precast planks with single-ply roofing. The partitions are to be metal studs with drywall. The ceiling is to be hung. The building will have a self-contained air conditioning unit. The manager has decided to define site preparation and utilities work as a separate package to shorten project duration which will be done before the foundation work. The foundation contract includes all foundation works (pile driving, excavation, etc.) for plant, warehouse and office. Since the owner expects to finance the building from current income, the warehouse and plant areas must be completed before any work on the office building starts. Steel erection can be started after pouring the slabs. During the office building, a temporary office will be will be established. The master schedule attached to the contract is shown in the following table. Project Master schedule Work package Max. Duration (days) Site preparation and utilities 40 Foundation and concrete work 55 Structural Work for plant and Warehouse 40 Interior work for the plant and warehouse 75 The structure and interior work for the office building 65 Site Amenities 25 11 Resource requirement The project manager has requested a resource-loaded schedule for “Site Preparation” as resource requirements have been only estimated for this stage. The resource requirement for site preparation is shown in the following table. There are only 20 workers available for this project. Activity Workers required Clear 4 Survey 5 Grade 4 Well 3 Tank foundations 4 Excavate sewer 6 Excavate manhole 2 Pole line installation 6 Pump 2 Underground pipe 8 Tank 10 Tank pipe 6 Connect 4 Install sewer 8 Electrical manhole 6 Duct bank 10 Prepare a resource-loaded schedule for this phase and level/smooth resource assignments as mentioned in task 9. The details of your resource levelling should be presented.
