A Study Of The Issue On The Determination Of Cost Claimed In Accordance With The Bill Of Quantities

With the promulgation of Code of valuation with bill quantity of construction works(GB50500-2003) in 2003, China cost engineering has entered to the pricing reform of theengineering detailed list stage. After the revision of the bill of quantities in 2008, it hasgradually maturation and become the major valuation model. Claim is the indispensable partof the pricing reform of the engineering detailed list, but it has only be ruled the procedure ofclaim, but not defined the constitute of claims expenses in bill of quantities which had arousedargument about whether claim include stipulated fees project list or tax project list. Theprimary cause is that domestic construction cost claiming is similar to internationalconstruction cost claiming, thus, the domestic study was focus on the examples ofinternational construction cost claiming. But they ignore that the extension concept ofmeasures fee and claim in domestic construction project is different from internationalconstruction project. Hence, based on the international construction cost claiming andcombined with the characteristics of valuation with bill quantity, put forward the systemframework of domestic construction cost claiming is meaningful and imperative. Focusing onthe issues above, this paper conducts the following research:1. Research on the system of domestic construction claiming: taking example by theconsistency of the constitute of international construction claiming cost and the constitute ofinternational construction tender offer, the assumption indicates that domestic constructioncost claiming includes subsection project claim, measures project claim, fees claim and taxclaim. At the same time, combined with Code of valuation with bill quantity of constructionworks (GB50500-2003) in 2008 and its promotion implementation, this paper revises theformer assumption: only with subsection project claim and measures project claim.2. Research on the system of subsection project claim: through analyzing the generalityof the constitute of subsection project cost, the object of this study is defined as labor claim,materials claim, machine fee claim, management fee claim and profit claim. At the same time,combined with three processing channels of project cost risks, the claim opportunity of eachfee claim is filtered out and method of determining the value of the claim is given, with theuse of the mechanism that each claim opportunity affects the project cost.3. Research on the system of measures project claim: through analyzing the differences ofthe constitute of measures project claim, the object of this study is defined as measure feesmeasured with metering, independent measure fees measured with items and comprehensivemeasure fees measured with items. Because the calculating methods of measure fee andmanagement fee, profit and subsection project are the same, this paper only discusses theclaim issues of labor fee, materials fee and machine fee. The identification of claimopportunity and the determining method of the claim value are the same with subsection project.Though the study, this paper obtains 3 results: the system constitute of domesticconstruction claiming, confirming the claims opportunity and claims value from subsectionproject, confirming the claims opportunity and claims value from measures project. The studyof this paper will lay the foundation of domestic construction cost claiming and provide a newidea for project claim practice.
