Among the most common types of construction contracts used in the engineering and construction industry are: in general, this contract is suitable only for construction and supplier projects for which different types of objects, and not their numbers, are specified in the contract documents. Approval of the architect`s recommendation for advancement payments to the contractor This list is not exhaustive, and in the section below, which examines key elements in construction contracts, there are other concepts that are often found in construction contracts, for which risk allocation is also appropriate. In most contracts, contract documents are „inserted by reference“. Contract documents typically contain plans and specifications, the „master contract“ between the owner and all major contractors, including the general contractor, grudges, building rules and rules, and changes to plans and specifications after the contract has been performed. Under a flat-rate contract, a „fixed price“ is agreed between the client and the contractor before the start of the work. This contract can also apply to both house construction contracts and commercial contracts. It may represent a lower risk for the contractor, as there are fewer mechanisms that allow it to vary its price. The difference between this type of contract, which is a cost-based contract with a fixed-price contract, lies in the fact that, in the maximum guaranteed price (GMP), where savings result from below-the-stroke costs, it would be an agreed price contract, and the contractors retain for themselves the savings resulting from the undercutting of costs and there is no obligation for them: return them to the owners. Nevertheless, this savings can be shared by both the contractor and the owner.
 There is another difference in the status of the plans. The lump sum contract can be used if the owner has a complete set of plans, specifications, etc. Otherwise, the maximum guaranteed price (GMP) will preferably be taken into account in order to compensate for this shortcoming. When cost-plus is used, it is best for the owner to determine the maximum guaranteed price in order to avoid other costs and contractors needed to provide the primary input to the owner on the project costs.  The two common categories of incentive contracts are: works contracts can be contracts: subcontracting can offer guarantees that can facilitate your work, while direct shutdown requires additional monitoring and management efforts. But the direct attitude often gives the client more control over cost and quality. How does a contractor choose between the two? Based on the scale of the project and the existing relationships with subcontractors, the project manager makes the decision on the basis of what is the least expensive and most timely. The portal on which all the correspondence between the contractor and the architect /engineer takes place This type of contract is based on the expected quantities of items that are counted in addition to their unit prices in the project. The final price of the project depends on the quantities needed to carry out the work. It is important that parties entering into a significant economic transaction have written contracts. This is especially true for construction projects that are complex.
A contract for a construction project defines the obligations of the parties between them and determines the allocation or allocation of risks between the project. . . .
