Spending costs in construction of road pavements has turned this subject into one of the significant points in transportation infrastructure of countries. Concrete slabs consider as a paving method with ability of reducing the rehabilitation needs. Therefore, to manage costs and optimize the thickness of concrete pavements, recognizing the amount of determinative factors’ influence will be requ...

Currently, Construction and Demolition waste (C&D waste) is a worldwide issue that concerns not only the construction management level of on-site managers but also the sustainable development of construction industry. In this paper, detailed formulas are listed for calculating the costs of three typical kinds of disposal routes of C&D waste. They are Landfill Disposal, Recycling and Reuse. Usin...

A residential building with a lateral load resisting system, adopted as a reference example, is considered in the paper. The system is made of shear walls realized using the tunnel form technology. The building is modelled for a varying number of floors, and the model is also used to consider the applicability of the technology with regard to construction costs. The influence of the type of soi...

Purpose Each production process in construction is closely connected with the question of costs and deadlines. In every project an investor or customer, as well as the construction company, has to meet the planned completion date and the estimated costs associated with the construction. In practice, determining the duration of construction at minimum costs is still not based on the reliable cal...

Building actors need accurate estimates in order to efficiently undertake the construction of buildings. The knowledge of real expected costs of construction works is a necessary condition for contractors to submit competitive tenders and for developers to be aware of the magnitude of their investment. In this paper, an innovative process-based model is presented, the POP model. This model aims...

Rework adversely impacts the performance of building projects. In this study, data were analyzed from 788 construction incidents in 40 Spanish building projects to determine the influence of project and managerial characteristics on rework costs. Finally, regression analysis was used to understand the relationship between the contributing factors, and to determine a model for rework prediction....

As global populations and affluence rise, there is increasing demand for energy, animal protein, and construction materials. In many cases, available resource pools are insufficient to meet growing market demands, resulting in increased prices and competition for limited resources. This study evaluates key construction resources needed to build different types and scales of Iowa swine productio...

Estimating in construction education has remained relatively unchanged despite continual technological advances. Currently, students conduct time consuming quantifications and take-offs from construction documents. This traditional estimating process is disconnected from the physical building leading to greater differences between estimated and actual construction costs. To remedy this conditio...
