Show transcribed image text 2. You are given the task to determine the duration (in days) and cost of a work package to build a masonry wall at the entrance of a public park. You were given drawings at a 1:200 scale for the park and you measured the length and the height of the wall as 2.4 and 0.6 inches on these drawings. Then you went to the Means database and found the line item shown in Table 1 for a simple masonry wall. Crew A1 consists of 2 people; 1 mason and 1 helper that both work 8 hours a day. a. What is the cost and duration (days) of the package? Unit Cost QTO UnitC Crew Labor Man Description hrs. hours Labor Mat. Equi 0.2 Masonry wall SF A1 0.5 0.125 SF-square foot b. One of the foreman later told you that by adding another Mason to the A1 crew you can improve the productivity to 0.18 hours/SF. You calculated that adding the extra mason would increase the labor cost by 40?% for a SF of the wall. What will be the new duration and cost of the package if you accept the foreman's suggestion?
