長隧道機電標價值工程研析之案例探討

CASE STUDY ON BID PRICE OF ELECTROMECHANICAL SYSTEM OF LONG HIGHWAY TUNNEL BY VALUE ENGINEERING

東西向快速公路漢寅草屯線八卦山隧道為雙孔雙車道,其橫貫於台灣彰化、南投兩縣,長約5km,設通風豎井1座(内徑9.5m、深度240m)及機房3座,主體工程已於1996年11月15日開工。該工程機電設備含電力、照明、消防、火警、通風、監控等系統工程,以確保用路人之安全與舒適。因工程龐大,乃透過價工研析,期將預算作最有價值之编列;本案例維持必要機能,採替代方案,有效節省成本約達新台幣3億元,投資報酬率86,為相當突出之價值工程研析案例。

Pakuashan Tunnel is a one-direction dual-hole dual-vehicle-lane tunnel about 5 km long, connecting Changhua and Nantou in Taiwan. !The tunnel has 3 machine rooms and one 'vertical ventilation shaft (9.5 m in inner radius, 240 m in depth). The construction started at 15 November 1996. The electromechanical system of the project includes equipments for electric power, lighting, water supply and drainage, fire control, fire alarm, ventilation, air condition of machine rooms, monitoring and control, and broadcasting. The budget is huge. Value engineering is used to control the budget and make it reasonable. The budget determined maintains necessary function, adopts alternative program, and effectively reduces cost about 3 hundred million NT dollars. The rate of return on investment is about 86.
