Circlet of the Contract Management

The contract management for supervising the construction work consists of the rotation of each process, such as cost estimation, proper procurement, supervision of the construction work and so on.
Hanshin Expressway (HEX) has been supervising a lot of contractors as the contractee and has developed its own methods to ensure the quality of the construction contract throughout many projects.

Cost Estimation / Contractee's Cost Estimation Price

One of the most important tasks in the circlet of the contract management is cost estimation.
We conduct cost estimation process in order to make contractee's cost estimation price through our own estimation regulation. Our sophisticated staff can estimate the construction price properly.

Background

"Price Competition" used to be the only principle for Public-Work Biddings by the Public Accounts Act and the Government Ordinance on budgets and accounting.
Nevertheless, the price-only competition method has the demerit that sometimes biddings get exaggerately low prices only to gain the contract, but less than those necessary to achieve expected quality. Furthermore there is a risk of Bid-Rigging by a price cartel, in which case the tendering enterprise would need to make less effort to improve technical matters. From such a background, "Act for Promoting Proper Tendering and Contracting for Public Works" was enacted in 2002 and "Act on Promoting Quality Assurance in Public Works" was enacted in 2007.

Completion Inspection / Contract Score

The completion inspection of the construction work is significant process to ensure the quality of the construction work. Contractee's inspection is conducted not only during the work completion time but also during intermediate time of the construction work, as we can't inspect everything at the completion time.
HEX also judges the result of the construction work and score the result. Then HEX informs the score to the contractor to use on the next step.
