The contractor can carry out the project in several ways. Often, they will appoint their own advisors or use their own in-house team. It is also customary for the contractor to take care of the employer`s advisors and continue to use them to complete the detailed design as part of a so-called innovation agreement. Duke and Carmen stated: “Cost-plus with GMP provides a cap on construction costs and total costs for which an owner is responsible. If the party that provides the work according to this method of price goes through GMP, it is responsible for such overruns… Cost-pluses with GMP and a cost-sharing agreement can encourage both parties to enter into a construction contract in the most efficient way possible.  The following types of contracts, for the performance of civil engineering work: A contract is a really important document that will define your volume of work and bind the owner to your services, including payment terms. It is really important that you understand the extent of the work indicated in the contract agreement, that you finish the work as planned and that you finish the invoice by instruction, and finally, it will be the tool that will be used so that you can get paid. An executed contract provides for a warranty period or a malfunction. Under this agreement, services have been provided, but the contract protects one party if the performance of the other party does not provide the correct guarantee of a defective or defective installation.
A national construction contract is a contract that includes all work that should be done for the construction of a purchase or dwelling building existing or taking place in a given country; not foreign or international. In the lump sum contract, all work is carried out according to plan and specifications by the contractor for a specified fixed amount, in accordance with the agreement. The owner provides the necessary information and the contractor calculates a certain amount. This contract is appropriate if the number of items is limited or if it is possible to develop exact amounts of work to be done. Detailed specifications of all work points, detailed plans and drawings, deposit, penalty, progress and other contractual conditions are included in the Convention. Although it is a lump sum and a planned contract, the contractor is paid at regular intervals of 2 to 3 months after demsol work on the basis of a certificate issued by the competent engineer. A planned price is included in the agreement for the payment of additional items. Measurement contracts can allow for an early start-up in the field before the project is completed, and they can allow for relatively easy modifications to the work. However, there is inevitably some risk to the client, as the cost of the work is not known.
