Here Is What I Understand About Navisworks Manage CostThe process at the planning phase is iterative; users are encouraged to go back and improve the 5D model until it is considered final and ready for the construction phase. At this point, the project team can approve the 5D model and begin execution . The developed EVM platform will then be used during construction as an executing, monitoring, and controlling tool. In the meantime, design and other changes brought during construction can be integrated to the building model and extended to the EVM platform in the same way as in the design phase . The 5D model will also be used during the construction as a visualization, communication, and coordination tool for every project’s stakeholders. The ITCMS workflow during the planning phase involves many processes that are linked to each other and can be iterated. During the execution phase, the processes are fully integrated and resemble a periodic check of the project’s health in accordance with budget and schedule baselines, using the EVM platform. Glavinich believed that constructability refers to the ease with which the raw materials of the construction process can be brought together by a builder to complete the project in a timely and economic manner. Tatum denotes constructability as the integration of the design and construction. Johansen and Wilson questioned the necessity of intense construction planning in the design phase; they reached a conclusion that there is reluctance within the industry to accept first planning initiatives. Their major finding is that there is a lack of convergence between the design and construction team planning ideas, thus preventing achievement of project success. Mismanagement, as per Chester and Hendrickson , originates from the drive to build cheaper and faster, designers performing a less thorough job and managers not planning as well as they should. Glavinich suggested that a design-phase scheduling and a check of drawings and specifications be performed before the construction would lead to less budget and schedule impact to the owner. With construction projects’ performance being evaluated mostly along budget and schedule considerations, it is imperative that time and cost control needs to be a major focus of the construction manager. An early involvement and proactive presence of a construction professional is needed during the development of the project plan to ensure that construction plan and schedule are sound. In the same direction, Miyagawa developed an automated and computerized system intended to control the manageability of the construction planning. The outcomes of this system are interesting and include noticeably the ability to integrate the project design with project planning, scheduling, and diagnosis techniques. Stevens presented the integrated cost/schedule performance curve that achieves cost and schedule control against project plan. Used as a visualization summary tool, it can also be used as a model for predictions and forecasts. Perera and Imriyas proposed the combined usage of MS Access and MS Project software as a project time and cost control system. Many construction projects suffer from poor design and from inconsistent time and cost management. This situation has led to rethinking of the industry’s performance and how it could be improved. Technology is breaking through design. Management practices. Earned value management enables better management of time and cost constraints. Building Information Modeling is recognized to improve the planning. Realization of a construction project. The present paper proposes an integrated time and cost management system , where an EVM platform is used in a virtual environment during the planning and construction phases of a project. The ITCMS enables early involvement and project integration plus thorough time and cost management. The system consists of four modules and 13 different proc
