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. This type of contract is suitable for large public works, such as infrastructure projects, which involve repetitive tasks and easily quantifiable resources. However, when a project involves several complex trades and activities, it is not particularly appropriate, as it can be difficult to accurately predict the quantities required for each unit. In summary, unit price contracts are well designed for projects with familiar materials and repetitive work units. This type of contract results in high performance, competitive and compliant pricing in the tendering phase and a common risk for all parties involved. Some of the falls can occur while working on more complex projects and the work is not perfectly defined for unit prices (z.B.
Project with all doors and door sizes… The installation scopes and equipment used in each opening would be different from the next.) Individual contracts are often used in engineering, landscape architecture, flat construction and housing. Home builders… Oh, really? Yes, unit work may not be repeated, but for manufacturers that offer a finite number of model options, it is useful in the grand scheme of things. For public works, you will often see a large number of lump sums for the estimated volume of work and additional unit prices for temporary positions. These are more difficult to estimate until work begins. (for example.B. geotechnical studies are not accurate in measuring excavation/earthwork requirements) The correct calculation of the contractual rates of the dredging project, whether calculated as a unit cost or a flat rate, is crucial. The simplest example of a unit price contract is probably the payment of dirt by weight. You may not know exactly how many charges will be required, so choosing an overall price at the beginning may not make much sense. However, throughout the duration of the project, it is important to follow and reassess this initial estimate. This is called “fairs” and “reassessment,” and it is precisely for this reason that unit price contracts are often referred to as measurement, measurement and salary contracts or revaluation contracts.
