我院在1977年对工程造价作过分析。分析中按五十、六十、七十年代和平原、丘陵、山岳三种地形分别作了统计,如平原地区以五十年代的造价为100%,则六十年代为107.5%,七十年代277%;丘陵地区五十年代为100%,六十年代108.2%,七十年代225%,山丘地区五十年代100%,六十年代129.8%,七十年代318%。造价增大的原因;属于设计方面的主要是根据运量要求和技术发展,设计标准大为提高,运营生产设备采用新技术、新工艺、提高机械化程度等,其次是为了支农节约用地线路往山靠增大了土石方,取弃土远运以及修路造田等。属于概算方面的有工资津贴增加;定额水平变动如工率调低,用料率调高;施工管理,拆迁购地,材料价格,临时房屋等费增加了。属于施工组织方面的如施工总工期难以落实,工程部署缺乏全面安排,施工单位远征或临时变更。
Our hospital in 1977 made an analysis of project cost. In the analysis, the statistics of the three terrains of the plains, hills and mountains were made according to the fifties, the seventies, seventies and the seventies. For example, in the plains, the cost in the 1950s was 100%, then that in the 1960s was 107.5% 277% in the 1950s; 100% in the 1950s, 108.2% in the 1960s, 225% in the 1970s, 100% in the 1950s, 129.8% in the 1960s, and 318% in the 1970s. The reason for the increase in cost is mainly due to the design requirements of transportation and technological development. The design standards are greatly improved. The operation of production equipment adopts new technologies and new processes to enhance the degree of mechanization. Secondly, Mountain by increasing the earth and stone, take away the remote transport and road construction and other fields. Wages subsidies belonging to the budget estimates increased; fixed level changes, such as reduced work rates, material rates increased; construction management, demolition purchase, material prices, temporary housing and other costs increased. Belong to the construction organization such as the construction of the total duration of the project is difficult to implement, the lack of comprehensive arrangements for the deployment of the project, the construction unit expedition or temporary changes.
