Bee, Andrew& Al Shanawa (MGA, Inc.), a Certified Public Accountant in Marietta, has approached your construction management firm requesting a feasibility study that includes a plan for construction activities that need to be completed by the start of the Spring semester. After meeting with your shareholders to determine whether or not it is in the company's best interest to go after this work for these particular people, you decide that it is worth the risk. During a preconstruction meeting, the project team develops activities and duration estimates that will drive the schedule, and provide enough information to the owner of your company to make a decision. The transcript from the meeting is on Page 3. These steps are the deliverables required for the midterm. After reading the transcript, complete the steps, in order, and answer the questions below. Step 1- Develop a dependency table showing activity relationships Step 2- Layout an AON network diagram, and develop a legend or key for each activity box. Step 3-Perform a Forward Pass, Backward Pass, and Float Calculation and clearly indicate the critical path with color or highlighting. Remember, a clear presentation to the owner (that's me) is crucial! This should be done by hand only. Use the fully constructed AON network diagram (steps 1-3 above) indicating the critical path, (a calendar with dates is useful to reference, but not a required deliverable) to answer the following questions: a. What activities make up the critical path? b. When is the proposed finish date? c. What are two near-critical activities? 2 d. If the Architect changes their mind, and the exterior siding material is delayed and does not arrive until Wednesday, November 6, 2024, causing this to be the earliest starting date for the activity, does this impact the finish date listed in question b.? How do you know? e. What is the new revised finish date if the carpenters that are responsible for the exterior siding cannot work the week of the 4th of November, assuming the material is delayed, and could only start back on Tuesday, November 12th? How do you know? f. If the insulation material is delayed and does not arrive until Tuesday, November 12th, 2024, causing this to be the earliest starting date for the activity, does this impact the finish date listed in question b.? (ignore previous delays in questions d. and e.) How do you know? g. What is the new revised finish date if the insulators cannot work the week of the 11th of November, assuming material is delayed, and could only start back on Monday, November 18th? How do you know? h. If the Rough Electric takes 4 additional workdays, does this impact the overall project? If so, by how many days? (ignore d. through g.) . If Dr. Moore and Dr. Al- Shenawa want to visit the jobsite on Thursday, November 21st, and the day after to play golf with Bubba, and it shuts down all work for both days because Bubba is a big hitter and everybody wants to watch, which activities will be impacted? (ignore d. through h.) Transcript "Alright. We need to start immediately, no time for delay. Use Monday September 30, 2024, as a starting point" "Bossman, do we need to work weekends and holidays to knock this thing out? I have some things planned for the weekends coming up and Thanksgiving." "No, we don't need to extend resources for that. No weekends or holidays, standard 5 day work week should do it. Well, we will certainly have to start with SITEWORK, and this will take 4 days probably" "After that, the UNDERGROUND UTILITIES can start, and I know we can knock those out in 12 days" "Since we are talking about the outside work, we would have to include 4 days for LANDSCAPING before we CLOSEOUT THE PROJECT" "Right, but we can't start the LANDSCAPING until EXTERIOR PAINTING is complete" "Duh, the UNDERGROUND UTILITIES comes before LANDSCAPING too, boss!" "How much time will we need for EXTERIOR PAINTING?" "5 days" "Okay, but we will have to complete the EXTERIOR SIDING and FINISH ROOF before then" "Yep, but let's get back to the beginning. The ROUGH PLUMBING should take 12 days, and needs to start 5 days after FORM/POUR SLAB starts, which will take at least 7 days to complete" "Do we have to wait until the UNDERGROUND UTILITIES are complete before we FORM/POUR SLAB?" "No, FORM/POUR can start right after SITEWORK, and we will have to wait until the slab is complete before starting to FRAME WALLS" "FRAME WALLS is crucial, let's put 5 days for that. Its completion allow ROUGH ELECTRIC, FRAME ROOF, and the WINDOWS/DOORS to start" "Okay, so let's say 7 days for ROUGH ELECTRIC, 10 days to hang WINDOWS/DOORS and the carpenters can FRAME ROOF in 7 days" "If the boys can frame the roof in 7 days, surely the roofers can FINISH ROOF right after that in 3 days as well" "Yep, FRAME ROOF will allow ROUGH MECHANICAL to start, which will take every bit of 5 days. ROUGH MECHANICAL cannot start until the UNDERGROUND UTILITIES are done either" "EXTERIOR SIDING can start after the WINDOWS/DOORS, and should take 5 days to complete" "Slow down boys, make sure you don't start the 6 days worth of DRYWALL until ROUGH MECHANICAL is complete, and Bubba - make sure they complete the FINISH ROOF firstbefore DRYWALL starts this time!" "10-4 Boss" "INSULATION might take 3 days, but needs to wait on ROUGH ELECTRIC, ROUGH MECHANICAL, and ROUGH PLUMBING to be complete before starting, but should be complete before DRYWALL is complete " "We need to start the ROUGH ELECTRIC as soon as possible, but after UNDERGROUND UTILITIES" "Great, so let's have 4 days for FINISH ELECTRIC, and 5 days each for FINISH PLUMBING, and FINISH MECHANICAL, and know that all three need DRYWALL to be complete before starting" "Correct, but don't forget about INTERIOR PAINT, which needs 4 days to complete, and needs to happen after DRYWALL and before FINISH ELECTRIC" "That should do it! Make sure that we have 2 days for PROJECT CLOSEOUT after the 3 FINISH MEP activities and LANDSCAPING to tie up any loose ends" "Sounds good. Great work boys!"|
