- Find the duration in days for a masonry job that has 24,000 bricks with a crew of five masons and three laborers. The work day is 10 hours. The productivity of the crew is 0.103 man hour per unit (9.7087 unit/man-hour).Estimate the total amount of cost for concrete works (class “B”) based from the following given: 10-pcs of F1 (1.2m x 1.2m x 0.3 m) 10-pcs of C1 (0.3 m x 0.3 m x 4.1 m) Floor area of 100mm thk slab-on-grade = 53 sq.m The cost of cement (40kg per bag) = 210 per bag. The cost of sand is 710 per cubic meter. The cost of gravel is 1900 per cubic meter.Answer the following, a) Given a Concrete Mix Ratio of 1:2:3, what is the computed number of cement bags per cubic meter of concrete? b) Given a Concrete Mix Ratio of 1:2:4, what is the computed required volume of gravel for 1 cubic meter of concrete? c) A team of 2 skilled mason and 4 laborers are assigned to work on a 20 cubic meter volume of concreting work. They finished the job in 5 days, working 8 hours a day. What is there Productivity rate for the activity? d) A concrete vibrator was rented for concreting works. Rent is at 750 Pesos per day. Concrete pouring was computed to be completed in 5 days, but was actually finished in 4 days. How much was budgeted for equipment rental? e) My database for Formworks and Falseworks Unit cost is Php 1, 040 per sq. m. If I am to Construct 4 columns with height of 2.5 meters per column and Cross section of 0.3m x 0.4m, How much should my budget be for my formworks and falsework- based on the Unit cost?
