In lump sum contracts or fixed-price contracts, the contractor assesses the value of the work in accordance with the available documents. Mainly, these documents can be specifications and drawings. In the pre-auction process, the contractor takes into account the costs of implementing the project (based on the above documents, such as drawings, specifications, schedules, tender instructions and details received for the requests raised). And the contrast with these contracting documents evaluates and has agreed with the owner (or employer) to complete the work without exceeding the agreed lump sum.  If an owner has an overview of what he wants, but the roadmap to get there is not very clear, unit-price contracts can work very well. Unit price contracts are essentially a series of lump sum contracts throughout the project. The project is divided into phases and a contractor will provide a fixed price to complete each phase. Have you ever wondered how a contractor and a contractor cost before a construction project starts? Or how was the basis of these costs pooled and what would be the changes in the scope of these agreed costs? Although this is a relatively simple approach, construction contract partners can often face several problems when it comes to cooperation for the agreed amount of the contract. In order to avoid such disputes, it is possible to use different types of contracts for which the total cost can be agreed in advance or measured and evaluated when the project develops on the basis of a refund. There is also no incentive for early completion of the project. Work is a direct cost, i.e. the more hours of work on the project, the higher the benefit.
With a lump sum contract, the contractor benefits from the early purpose and entry into the next project. There are other contracts that could create a better, more lucrative or more creative project for both the owner and the contractor. If a complex project is on the table or the owner is not quite sure what he is looking for, it may be worth a look. A unit contract is based on estimated quantities of materials for the project and their unit prices. The final price of the project depends on the quantities required to carry out the work. This means that before work and contract, the different materials are known, but the quantities cannot be identified. In a single-rate contract, the contractor offers a price for each material during the tender. The list of unit games per item can make it easier to calculate any changes or changes and avoid risks. In reality, however, this can be likened to a flat price. This is particularly the case when the proponent asks the contractor to accept the risk of a proper assessment of quantities, rather than allowing a reassessment of quantities in light of what happens on site during the work.
Projects that progress under a lump sum contract have, by their very nature, very few paper requirements. Payments are usually made according to a progress plan, so owners do not have to deal with equipment costs and hours of work. This means that contractors do not need to create detailed invoices or complex paid applications. Payments are simple. As part of a contractor`s offer, the lump sum contract is usually divided into several packages, either on the basis of a quantity calculation or in the form of an analysis of the amount of the contracts. In both cases, one of these packages is a specific pre-tour. Preliminary work is an integral part of the tender file and includes a description of the project, allowing the contractor to assess the costs of starting the work. Specific preliminary work may include items such as site construction costs, social equipment and traffic management measures, as well as facilities and machinery.
