實施項目過程中，“例外”的情況往往如下：
(1)The amount of importance:the general view is a significant difference of money, only referred to
as "exceptions".The determination of the difference between the amount of cost, is based on different percentages of the original standards in accordance with the specific conditions. Variance includes favorable and unfavorable difference. The actual costs are less than the standard
cost too much is not a good thing, it may result in two scenarios:
（1）金額的重要性：壹般的看法是錢的明顯差別，將僅被看作為“例外”。成本金額之間差別
的確定是基於附合具體條件的原始標準的不同百分比。差額包括有力的差別和不利的差別。實際成本低於標準成本太多並不是壹件好事，它可能導致兩種情況：
One is that the follow-up to the sub-part of the project will be adversely affected;the other is low quality，In addition to the possible redesign and increase maintenance costs, cost control also affect the quality of business reputation.
其壹是進行項目子項的後續工作受到不利的影響。其二是質量下降。除了可能的重新設計和增加維護成本外，成本控制也會對商業信譽的質量產生影響。
(2)Consistency; Despite some differences did not exceed the cost of the minimum amount or percentage,but it has been hovering near the limit on the line of Con-
380 trol，this should also be regarded as“exceptional”It means that the original cost projections may be not accurate，and should he timely adjusted according to the actual situation.
（2）壹致性：盡管有些差別不超過最低金額或最低百分比的成本，但它已經徘徊在380控制線（這裏原稿可能打錯了，是猜的－譯註）的限制附近，這也應該被看成是“例外的”。它意味著原始的成本測算可能不精確，他應根據實際情況及時加以調整。
(3)Control capabilities:Some items are beyond the control of management costs，even if significant differences,it is also regarded as "exceptional"， such as land acquisition，demolition, the rising cost of hiring temporary.
（3）控制能力：某些項目超出了管理成本的控制範圍，盡管差別很明顯，但它也被看成為“例外的”，例如土地征用、拆遷、臨時租用成本的上升等。
(4)Particularity:For the special construction of the project influencing the cost of the entire process，even if differences don’t achieve the importance. The staff should also be close attention to cost control，like one-sided emphasis on conservation of mechanical maintenance costs .Although the cost can be lower in the short term,but a lack of maintenance may cause the suspension of repairs thereby affecting the smooth construction of production.
(4)特殊性：對於影響整個過程成本的項目的特殊建設來說，即使差別沒有達到重大的程度，工作人員也應密切註意成本控制，比如單方面強調機械維護成本的維持。雖然成本在短期內可以比較低，但缺少維護可能引起修理工作的懸而不決，從而影響到平穩的生產建設。
3 Effective Ways to Control the Construction Project Cost
控制建設項目成本的有效方法
There are many methods to control the construction project cost，the effective ways could be sure to achieve the objective of the project cost by cutting down the cost and increasing the revenue.
控制建設項目的成本有很多方法，有效的方法確實可以達到項目成本的目標，其方法就是降低成本和增加歲入。
3.1 In accordance with the principle that the amount and the price should be separated，control the project direct cost
3.1 按照金額和價格應該分離的原則，控制項目直接成本
Project direct cost mainly refers to the direct cost of the project entities and the cost for labor, materials，machine use, and other direct use，which contribute to the formation of the project，in the course of forming the construction project cost. According to the principle that the amount and the price should be separated，we should give effective control to the following aspects.
項目的直接成本主要指的是項目實體的直接成本和在建設項目成本的形成過程中的勞動力、器材、機器的使用，以及對項目的形成做貢獻的其它直接使用的成本。按照金額和價格應該分離的原則，我們應該對以下幾個方面進行有效的控制。
3.1 .1 Materials cost control
The cost of materials usually accounts for 65% to 75% of total project costs, that directly affect the project cost and economic effect. General practice is doing a good job in two aspects mainly in accordance with the separation principle of the amount and the price.
3.1.1器材成本的控制
器材的成本通常占項目總成本的65％～75％，它直接影響到項目成本和經濟效益。壹般的做法是主要按照金額和價格分離的原則做好兩方面的工作。
