Abstract
Field practice is the work that has been done to gain knowledge and to have practical experiences through direct observation. The field practice programs provide an opportunity to apply previous knowledge, view real examples set in a worldly framework and opportunity to be involved, physically, with real situations in the field. All of this promotes a deeper understanding of the subject being studied and an improved ability to recall the information and experiences, later as needed.
The activity that was performed was Detailed Engineering Design for the Irrigation Project. The preparation of detailed engineering design of check structure includes the validation of the proposed site for the irrigation project, topographic surveying and generating a topographic, map, preparation of detailed engineering design and preparation of the program of works (POW) or cost estimates for the proposed check structure.
The activity was performed using a total station and a levelling staff to gather the elevations and coordinates that are needed for the generation of topographic map. Data gathered was saved and imported in the CAD software to generate the topographic map. List of materials and works was then prepared for the program of works (POW).
The site validated was Barangay Bolo, San Jacinto, Panagasinan. It has an irrigable area of 20 hectares and a catchment area of 90 hectares. The selected design flood discharge, Q, was 45 cubic meters per second (m3/s). Upstream apron elevation was 37.0 m. Downstream apron elevation was 36.5 m. Length of crest was 30. m. The total direct cost estimated for the construction of the check structure in barangay Bolo, San Jacinto, Pangasinan is Php 15,300,000.00 and meets the Php 200,000.00 development cost per hectare set by BSWM for the improvement construction of check structure.
