How to control or minimize the cost of construction projects? Having a control over project cost is seriously difficult for contractors, architects, engineers and owners until and unless extremely productive tools and techniques are applied by them for accomplishing the project. Design and construction professionals should start using high-tech tools such as design development software like AutoCAD and Revit in the preconstruction phase of the project so that actual construction process can be successfully streamlined by them. Project cost can only be controlled by design and construction professionals if final construction is carried out flawlessly by them. That means if situations related to rework are confronted by architects and engineers when the final construction takes place, putting a check on increasing project cost becomes next to impossible. This clearly indicates that key building professionals should make it sure during preconstruction itself that they should not be indulging into any kind of rework at the time of final construction.
For the complete elimination of rework, clients have to make use of architectural and engineering solutions which are generally hired form engineering service providing companies in preconstruction. These services are a mixture of both CAD and BIM services which include drafting, modeling, clash detection and coordination services etc. Generally clients hire CAD drafting services for all the fundamental building disciplines like architecture, structure and MEP. That means architectural, structural and MEP drafting services are truly very necessary for building construction as they provide explicit information about the design of individual building trade to clients. But for the better representation of the design of individual building trades it is important that
architecture, structure and MEP modeling services are hired. When BIM modeling services for multidiscipline building trades are hired design and construction professionals can conveniently deal with building elements in 3D. The potential challenges of the proposed design become clearer to Architecture, Engineering and Construction professionals when the physical structure of building elements is effectively viewed by them through multidiscipline parametric models. With the assistance of 3D design clashes between building elements are easily spotted by modelers when they perform clash detection, which helps in the removal of onsite rework. That means if building design is effectively checked for errors, rework which enhances project cost can be totally removed in preconstruction itself. This ultimately helps in controlling project cost.
