Problem Estimate the TOTAL COST needed for Excavation, Gravel Bedding, and Concreting Works (Excavation + Cement + Gravel + Sand). Do not round off your answer. Parameters to consider: No allowance or factor of waste. Use Class AA Excavation Cost = 300 pesos per sq.m. Use 40 kgs bag Cement = 300 pesos per bag 100 mm thick gravel bed (include this in estimate) Sand = 1000 pesos per per sq.m. All footings lie on gravel bed (except FTB) Gravel = 900 pesos per per sq.m. D=1.53, I=16, and J=24 givens are in meter. What to estimate: For Earthworks: • Footing and Footing Tie Beam For Concreting Works: • Footing • Footing Tie Beam • Columns Additional: • Gravel Bed (Estimate the volume needed and include the cost in the total cost) GIVEN: A= 1530 B= 330 C= 1630 D= 1.53 E= 430 F= 480 G= 280 H= 860 I= 16 J= 24
