4、 characteristics. Depending on the methodof arriving at the contract sum, building contract fall into 3 categories:n Lump sum contracts;n Measurement contracts;n Cost reimbursement contracts. 所谓总价合同是指业主付给承包商的款额在 合同中是一个规定的金额，即总价。总价合同有 以下四种不同的形式。1) 固定总价合同（Fixed Lump Sum)适用范围及特点：n工期较短；n最终产品要求明确；n设计完整，发
5、发包工程内容及技术经济指标明确；n合同总额是一个规定的金额；n如果设计和工程范围有变更，合同总价也必须相应变更。1. 总价合同(Lump Sum Contracts)2） 调值总价合同（Escalation Lump Price)适用范围和特点： n 工期较长； n 最终产品要求明确； n 设计完整，发发包工程内容及技术经济指标明确； n 合同按照时价计算，总额是一个相对固定的价格； n 由于通货膨胀导致人工、材料等成本增加，合同总 价也必须相应调整。调价方法：文件证明法和调价公式法。调价方法：n 文件证明法凭正式发票向业主结算价差。 n 调价公式法C=Co(0+ 1M/M0+ 2L/L0+

Usually it is necessary to consult a lawyer for adequate advice and guidance in dealing with the unique facts of a case.(2) Stipulated-sum contracts have a particular legal character that may be characterized as “a complete job for a stipulated price”; this may not r

10、o the site, and to pay for the work as it is done according to the contract.(5) A designers primary duties are to issue the certificates for payment and completion required by a contract when they are due; to issue written interpretation of the contract when required; and to seek the performance of
11、the contract by both parties when so stipulated( as in the standard forms of contract).Summary of Key Points for SSC(6) Changes can not be made by the owner in SSC without mutual agreement of the contractor; either as stated in the contract( as in the standard forms of contract)r, or as mutually agr
12、eed to subsequently by the parties.(7) Subcontractor should contain the conditions of the primary contract, insofar as they are pertinent.(8) In SSC, the contractor is paid to carry the greater burden of risk by the owner, who carries a lesser burden of risk.(9) To the extent that SSC allows changes
13、 in the works, the owner is open to risk from excessive costs.Summary of Key Points for SSC(10) SSC require the design to be practically complete and settled before bids are sought; but this precludes an owner from using a contractors knowledge in the design of the work, and to a significant extent
14、in its implementation.(11) The best kinds of work to be done within a SSC are those of straight forward design and of standard construction.Summary of Key Points for SSC当准备发包的工程项目内容、技术经济指标一时尚 不能像采用总价合同时那样明确、具体地予以规定 时，则以采用工程单价合同形式为宜。工程单价合 同有以下两种不同的形式。 1)估计工程量单价合同（Bill of Approximate Quantities Contra

16、A unit price is an average price per unit of an item of work.(2) In North America, UPC are limited to engineering construction, but unit prices are used in SSC to price changes in building work.(3) UPC usually require adjustments in the unit prices when quantities of items of work done vary by more than a stipulated amount( typically, 15 percent).(4) With bids for UPC, an owners consu
