Material waste minimization techniques in building construction projects

Construction Waste Generation in the Iranian Building Industry

Building industry as one of the greatest industries in Iran comprises a significant share of waste generation in the country. Since a large quantity of the generated construction waste is buried due to the lack of a recycling protocol, it leads to an undesired waste of resources and causes severe environmental issues. This paper provides a study on the problem of material loss/construction wast...

Modeling construction time in Spanish building projects

The literature states that project duration is affected by various scope factors. Using 168 building projects carried out in Spain, this paper uses the multiple regression analysis to develop a forecast model that allows estimating project duration of new builds. The proposed model uses project type, gross floor area (GFA), the cost/GFA relationship and number of floors as predictor variables. ...

Economic and Operational Feasibility Analysis of Solid Waste Minimization Projects

Autonomous Construction with Compliant Building Material

In this paper, we develop an autonomous construction system in which a self-contained ground robot builds a protective barrier by means of compliant pockets (i.e., filled bags). We present a stochastic control algorithm based on two biological mechanisms (stigmergy and templates) that takes advantage of compliant pockets for autonomous construction. The control algorithm guides the robot to bui...

Material delivery problems in construction projects: A possible solution

Emerging project management methods for construction projects generate new kinds of challenges for the delivery process of materials. The rationale of such methods is to create short-term schedules, based on a constraint analysis of resources, for project tasks. This approach has two requirements for material deliveries: transparency of material availability and short response times in the supp...
