In a proposed highway undergoing road earthworks, the given roadway cross-section notes are as follows: STA 20 + 100 3.00 1.50 1.00 -8.50 0.00 6.50 STA 20+ 300 2.20 1.20 2.60 -7.70 0.00 8.10 Width of the roadway is to be determined using side slope of xH:1V where x is the unknown horizontal side of the slope. Show and draw plotted points of the cross-section of roadway each station. Calculate the following: 1. Total number of man-days to finish the earthwork job 2. Total cost of machine rentals to finish the earthwork job. In the inventory of available heavy equipment on site are three (3) hydraulic excavators with bucket payload capacity each of 0.76m3 and one (1) hydraulic excavator with bucket payload capacity of 1.15m3. The hourly production of each excavator with 100% efficiency are 149m3 and 196m3 respectively. Daily machine rental fees for smaller capacity is 1,200 pesos while bigger capacity costs 2,200 pesos. Daily machine operations is limited to 8 hours.
