In November 2016, the company...Hi Can someone help me with this please. I just want to be sure Im on the right trackHOMEWORK 1 – ANDERSON ASSOCIATES Anderson Associates of Bridgebury, Connecticut, performs general construction work. In November 2016, the company had four jobs in progress: two twelve-family apartment houses, a gas station, and a four-store addition to the Rancho Shopping Center. The owner of the shopping center, Mr. Puckett had recently returned from Akron, OH where he had discussed with the executives of a large tire company the possibility of opening a tire sales and service shop in his shopping center. Mr. Puckett decided that a tire shop would be a profitable addition to his shopping center. He called Ms. Anderson, the President of Anderson Associates, to arrange a meeting to discuss plans fro the building. During their meeting Mr. Puckett and Ms. Anderson agreed that a suitable building for the new tire shop would be a one-story frame structure somewhat similar in design to the gas station that Anderson Associates had under construction at that time. Although time was short, Mr. Puckett was anxious to have the tire shop building finished by the time the addition to the shopping center was completed. He felt the grand opening of the tire shop should be tied in with the opening of the four stores in the new addition on Thursday, January 26, 2017. Following his meeting with the shopping center owner, Ms. Anderson spoke with Mr. Montero, Anderson Associates’ planning specialist. Realizing time was short, Ms. Anderson asked Mr. Montero to plan the construction schedule for the tire-shop building. Mr. Montero was instructed to use the plans and costs of the gas station under construction as guidelines for his preliminary planning of the tire shop. The actual project would commence on the following Thursday, November 21, 2016. Ms. Anderson wanted the plan to ignore Sundays and holidays and plan work for each of the fifty-four (54) working days between Monday and the opening. In his initial analysis of the problem, Mr. Montero noted the following relationships generally found in construction of this type: 1. A preliminary set of specifications would have to be completed before work could begin on the set of blueprints. Blueprints had to be finished before the foundation excavation could begin. After the excavation was completely finished, the foundation could be poured. Construction of the frame could not begin until the lumber had arrived at the construction site and the foundation had been poured. Installation of the automobile lifts could not begin until after the foundation was poured. 2. The preparation of the bill of materials (BOM) could be performed after the preliminary set of specifications were completed. When the bill of materials was completed it would be used to prepare order invoices for lumber and other construction materials. 3. After the frame was completed, workers could start on both electrical work and installation of siding. After electrical work was finished then plumbing and wallboard could start, as well as millwork. 4. Painting of the interior could not start until the wallboard had been installed. To avoid re-work, it was necessary to complete plumbing before working on the wallboard. 5. The final interior decorating work could not begin until the interior walls were painted and the trim was installed. Installation of the trim could not begin until the millwork was completed and the wallboard had been put up. 6. Painting of the building’s exterior could not proceed until the windows and doors were installed. Installation of the windows and doors, in turn could not start until the siding was in place./tutors-problems/Business/1071616210716162tive schools?
