Time - cost - quality model in controlling the cost of highway construction materials

Abstract

To control costs in general and construction material costs in particular in construction investment, especially highways, there are many methods. However, the cost of construction materials is closely related to the requirements for construction quality and has a relationship with the time (progress) of project implementation. Choosing a research model and research hypothesis that clarifies the relationship between time - cost - quality in a scientific way has an impact on helping the cost control process have a scientific basis.

The goal of the article is to synthesize domestic and world research related to controlling construction material costs, selecting models and research hypotheses, and the relationship between quality and progress. Progress and cost of construction materials in the relationship model Quality - progress - cost in cost control of highway construction material prices.

Keywords: Quality - time - cost model; material price control; highway.
