Description
Technical field
The present invention relates to highway engineering technical field, more particularly to a kind of highway engineering material cost difference method of adjustment and it is
System.
Background technology
At present, highway engineering takes quantity of goods produced method to carry out material and adjusts poor mostly, i.e., made by the bill of quantities budget of reply
Valency data file calculates the unit materials consumption of each metering specific item, consumption of materials=specific item metered amounts × unit material
Material consumption, adjusts the difference amount of money=consumption of materials × material cost difference × difference coefficient, and it is calculated such as formula 1.
Material adjusts the difference amount of money=∑ (specific item metered amounts × unit materials consumption × material cost difference) × difference coefficient
(formula 1).
Existing quantity of goods produced method adjusts poor " calculating consumption of materials according to the inventory documents of estimate " regulation of price difference, is deposited in end item
There are unit price and quantity in bill of quantities, and the specific item is miss out in inventory documents of estimate, existing cannot carry out material consumption
The situation of calculating, causes part specific item to carry out real material and adjusts poor, and is related to specific item too many in highway engineering, also has
Following defects：
(1) censorship difficulty is big
Because bill of quantities specific item is more, administrative department is needed to each specific item construction unit material consumption using quantity of goods produced method
Amount and current material cost difference are examined, because data are not directly perceived, lack macro-indicators reference frame, administrative department's censorship
Amount is big, and the cycle is long, and efficiency is low.
(2) it is unfavorable for the development of negative tune difference work
Currently, material adjust difference basic data from contractor submit to data, when price differential be on the occasion of when, contractor is carried
The enthusiasm of friendship data is very high；When price differential is negative value, contractor submits being short of power for data to, causes negative tune difference work to be difficult to
Carry out.
(3) it is unfavorable for that entirety is carried out to capital projects funds raises arrangement
The difference amount of money is adjusted with property afterwards based on the material that quantity of goods produced method is calculated, it is impossible to grasp the whole province's construction project material in advance
Difference macro-data is adjusted, and carries out capital collection arrangement accordingly, the passivity for causing fund planning to manage.
(4) it is unfavorable for the risk management and control of material cost
It is management and control of the owner to investment risk, contractor to material cost risk that material adjusts the essence of difference management, in face of valency
Lattice wave is dynamic frequently to need constantly lifting level of risk management to tackle with violent material market, owner and contractor, current material
Material adjusts the price differential of the consumption of difference administration base quantity of goods produced and material unit price, and the guiding to lifting risk management ability is not enough.
