tower cranes are major and expensive equipment that are extensively used at building construction projects and harbors for lifting heavy objects to demand points. the tower crane locating problem to position a tower crane and supply points in a building construction site for supplying all requests in minimum time, has been raised from more than twenty years ago. this problem has already been so...

In recent years, there have been significant advances in modeling technology for object-oriented building products. However, the building models are still lacking of providing construction-specific spatial information required for construction planning. Consequently, construction planners visually analyze building product models and derive geometric characteristics such as bounded spaces and ex...

How can savings in construction of your new maintenance building be realized when today's building and construction costs are at all-time highs? Metal building systems offer certain economies, from getting the building up and ready to use sooner to reduced maintenance for years after the building is complete. One big way "systems buildings" can cut costs is by speeding design, bill of materials...

This paper analyzes utilization of renewable energy systems and efficient building envelopes in the semi-arid climate. The proposed model evaluates renewable energy systems solutions as well as economic- and energy-efficient construction materials for the net zero-energy buildings (NZEB) in semi-arid climates. The objective of this paper is to optimize total energy cost and environmental impact...
