The tender projects include details of the construction project, which is too general. The tender design is aimed at selecting a contractor and speeding up the investment process. On the other hand, detailed designs explain in detail all the elements that are not included in the construction project. This is a list of technical instructions addressed to investment contractors. The documents required by law for the purposes of selecting a contractor are tender documents, i.e. estimates, specifications and lists.Types of estimates - how do they differ?
estimates - represent all construction and installation works in the order in which they are performed, as well as the basis for determining work prices and material costs (indicates the use of specific catalogs - PRC, PKZ, KNPR). The cost of the service will be determined based on estimates from a potential contractor.The investor's cost estimate is based on a statement of work volumes, and its purpose is to present the total cost of investments by setting costs for all stages of work for people and equipment, as well as prices for building materials. The advantage of such an estimate is a thorough financial analysis of a variety of construction options. Estimate proposal - submitted by the contractor on the basis of documentation and a list of works, includes the proposed price at which the contractor can perform these works included in the list of works. If the documentation is available to many companies, it will be possible to choose the best offer. It is important to remember that the cheapest performance does not always mean the best. An executive estimate is created to calculate remuneration if there are any changes that do not depend on the contract, the statement of work volumes or the estimate of the proposal. The execution of this estimate is very often outsourced, mainly during repair work. This is often due to inaccurate takeoffs or job changes.Assembly design – tasks and advantages
It consists in the computational analysis of each of the construction stages and the selection of optimal solutions that will reduce the work to a minimum. The construction process must be coordinated with the workers. The design is calculated in such a way that the appropriate load system can be selected for it. The advantages of this design are increased safety during construction work, as well as ensuring smooth and fast assembly of the structure.
