1) Renewal contract method

When it is necessary to intensively perform the same type of work for a certain period of time, such as bridge floor slab replacement work, seismic reinforcement work, investigations and designs necessary for ordering work for similar work, In order to facilitate discussions, etc., work that is ready for ordering is contracted as "initial ordering work", and work to be carried out after the completion of design and survey is contracted as "subsequent work".

With this method, we aim to improve the safety and quality aspects by utilizing the know-how in the initial contract construction for subsequent construction, and reduce the burden on both the ordering and receiving parties by streamlining the contract procedure.

2) Technical proposal / negotiation method (technical cooperation / construction type)

The technology proposal / negotiation method is for the construction where it is difficult to determine the optimum specifications or the conditions that are the preconditions of the specifications, and the construction contractor is confirmed by the examination of the technical proposal, and the specifications are negotiated by the technical proposal and the price. It is a method of selecting the highest bidder that allows you to confirm and determine the contract amount.

Among the technical proposal / negotiation methods, “technical cooperation / construction type” is an efficient design work by implementing technical cooperation such as construction plans of construction workers and carrying out detailed design reflecting the technical cooperation. It is a contract method that can be expected to confirm specifications and smoothly start and implement construction.

Our company also introduced it to floor slab replacement work for bridges of complicated structure, etc., referring to "Technical Proposal / Negotiation Method Operation Guidelines for Ministry of Land, Infrastructure, Transport and Tourism Works", and used the know-how and excellent technology of the builders Reflecting this, we aim for rational design and efficient business implementation.
