Abstract
Value Engineering is an analytical method used to optimize costs, consisting of negotiations, searching for substitutes and more efficient use of raw materials. It can be an effective support in defining material solutions while designing energy-efficient buildings. The research method adopted in this article is an analysis of the literature on value engineering and on the added value of the construction project and analysis of empirical data concerning an exemplary design solution for external walls in a multi-family building. It has been assumed that the reduction of the projected costs of the construction project (elimination of resources which do not create added value for the client) and at the same time increasing the energy efficiency of the facility are possible under the conditions of applying value engineering. The result of the calculations is the reduction of project costs according to the proposed model of value engineering.
Highlights
E.g. aerospace, automotive, mechanical, computer, etc. value management is an important part of the process of controlling production costs [1]
Calculations were made in order to provide data for the assessment of design solutions, taking into account both the planned function of the elements of the structure of the examined object and the costs of implementation of a given solution
The example mentioned in the article is only one of the possibilities when it comes to the selection of design solutions which have a positive impact on the thermal and humidity parameters of buildings
Summary
E.g. aerospace, automotive, mechanical, computer, etc. value management is an important part of the process of controlling production costs [1]. It is observed that few design offices or contractors apply techniques that allow for optimisation of investment implementation costs while maintaining the requirements imposed by the client. Value engineering differs from standard cost reduction methods based on the use of cheaper materials or resignation from certain product functions Such a procedure leads to a reduction of expenses necessary for the implementation of the project, but usually at the cost of quality and reliability. Bearing in mind contracts with amounts of several tens or hundreds of millions of Euro in mind, this allows for maintaining a significant amount of money in the budget, which can be allocated to other projects, without any loss of functionality or deterioration of the quality of the constructed object [5]
