Engineering Question
Q1) A subcontractor needs to install flooring. In the area has old vinyl tile, it must be removed and replaced by with new vinyl tile. Additionally, the concrete slab needs to be topped with ceramic tile. This simple project is broken into the activities shown in the following table A) Draw the resource histogram based on early start schedule. B) If the maximum number of labors available to utilize each day is 4, does the subcontractor able to accomplish this project on time? Show all your calculations. C) Level the resource so that the subcontractor does not use more than 6 labors at each day. Q2) A project and its activities are summarized in the below table. Given that the indirect cost is $ 1100/day, shorten the project duration (by one day each iteration) to find the following: A) The minimum duration of this project that could be shortened to. B) The project duration that provides the minimum cost. Q3) A construction project with its activities is summarized in the following table. It is anticipated some delays would affect some activities where they are summarized in the following table. No. Description Effective dates Delay time Activities affected 1 Equipment not on site 4-5 2 A 2 Working on site stopped due to weather condition 13 1 C 3 Late supply of drawings 15-16 2 D 4 shortage in the number of workforce (labors) 23 1 E 5 Inspection by the client is performed 30 1 G Do the following analysis by showing the necessary calculations. A) Draw the as-plan schedule. B) Draw the as-build schedule. C) Determine the net working duration. D) Determine the critical path/s and the total delay on the primary critical path. E) Determine how much each party is responsible for the contract delayed completion. Q4) At the beginning of a small engineering project, the below AON diagram was established. The duration unit of each activity is days. At the end of the 10th day, the field progress report gave the following information: • Activity “A” was completed on time. • Activity “B” was completed 1 day later than planned. • Activity “C” started as planned, but 2 days were lost due to waiting for the required materials. • The remaining duration for activity “D“ is 2 days. • Estimated percentage of completion of activity “E“ is 80%. • Estimated percentage of completion of activity “F“ is 50%. • Activity “J“ can’t start until the morning of day 13. • Due to owner requirement, the volume of the work of activity “M“ will be decreased by 25% . A) Update the AON diagram B) Calculate the activities times and find critical path. Q5) At the end of the 7th day of a small engineering, the field progress report included the following information. • Activity “A and B” were completed on schedule • The completion percentage of activity “C” is 33%. • The completion percentage of activity “D” is 50%. • Activity “E” has not started yet. The initial gantt chart of the project is shown below. The cost of each activity is given in the following table. Additionally, the below table is the field report at the end of day 7. Calculate the CV, SV, BAC, EAC, ETC, and comment on the progress of the work.
