Abstract
Tender price is often affected by the location of the construction, which is usually determined by the investor, and it has an impact on the traffic in the particular location. Individual time of supply and the method of realization play an important role as well. They both are determined by the investor along with the designer of the particular construction. Contractors often complain about the lack of time needed for the preparation of their tender prices. Therefore, it is necessary to look for the possibilities how to reliably speed up this process at the same time taking into account all of the specific features of a structure. This article deals with the application of two statistical methods. The Pareto analysis, which can be used during the design of the tender price, and the extrapolation method, which can be used for the estimation of the price development, based on the regression analysis of the time series. The results of the article particularly serve to contractors in the building industry to better prepare their price offers in tenders. The findings of this document may also be applicable in other countries which have a similar economic profile as Slovakia.
Highlights
Based on the needs of the construction practice, certain statistical methods are used more frequently
The tender price must take into account all the specifics of the construction contract, which result from the individuality and the character of the particular construction, such as the layout, the design, the architectural solution, as well as the operational and ecological solutions of a structure [14]
Instead of the individual price policy, which responds to a specific part of a construction production, for the preparation of the construction contract Slovak construction companies still use the tender prices, which only indicate the approximate prices of all the construction works
Summary
Based on the needs of the construction practice, certain statistical methods are used more frequently Their aim is to analyze several problems within the investment process during the preparation and the realization phase of the construction contract. Traditional methods of determining the offering price using the detailed budget are being replaced by innovative approaches for evaluating the building flow already in the phase of construction preparation. The prices of building work and materials as well as other commodities change their value over time; it is sensible to account for this development, especially during times of greater value deviation, by adjusting the offering price by a reasonable amount This article explores this problem and its solution using the second degree multinomial
