This project for water and electricity place office building, located in gansu province BaiYinShi PingChuanOu. Seismic fortification intensity of 7 degrees, design benchmark period 50 years. Basic kN/m2 wind pressure, basic snow for kN/m2 pressure. The project covers an area of about 7 square meters, with a construction area of square meters. This building altogether three layer, which is meters tall, indoor and outdoor level of m, m high parapet walls thick 250 mm. Interior wall thick 200 mm. Building the total length of m, always the width is meters. The building elevation of neat, use ceramic tile wall decoration. Except for the glass door in the front door, the others all USES plywood door, window for window of model steel window. This engineering structure form for frame structure, the column the sectional for 700 x 600 rectangular column, the main girder section for 300 x 600 rectangle beam, second beams cross section for 250 x 450, 250 x 500, 250 x 600 three rectangle beam, foundation, column, beam, plate is using C30 concrete, construction site geological condition is good, the beam type down the construction organization design including two volumes: first volume for the technical standard, the second volume for bid price quotation. The construction organization design part, main determined the preparation for construction and plan, construction general layout, construction technical scheme, construction quality assurance technology measures, schedule and time limit for a project assurance measures, the allocation of labor resources, etc. According to the fixed time limit and the actual situation, make sure the project total time limit is 102 days, among them foundation construction period for 15 days. The main body of the project period 46 days. Decoration construction period of 33 days. For the bid part, first through the list valuation calculated engineering quantity list rules, to use GuangLian valuation of software, by 2004 the gansu province construction engineering consumption quota "and 2012 quarter in the silver market, finally obtained in gansu province PingChuanOu hydropower office building project total cost is yuan RMB, the cost for home remedy yuan/m2.
