This project aims to demonstrate how multi-disciplinary coordination use in BIM can benefit the AEC (Architecture, Engineering & Construction) industry. It focuses on BIM applications for effective design analysis, productive design and coordination. BIM offers most advantages early during the design stage. Design validation co-ordination and scheduling are some of early tasks in construction. By using the data information from the design stage 3D BIM or by generating a new BIM model based on 2D design intent and specification documents, the team can start early in validating design intent constructability by performing clash detections, 3D coordination and visualization of different discipline, and by 4D modelling or construction sequencing simulation. This early task in construction is both beneficial for early construction planning and also during the construction proper stage itself. This report is to show the qualities of BIM and the influence it will have on the quantity surveying profession, through the opportunities and barriers that it brings forth, and the changes to be made and measures to be taken by quantity surveyors, in order to successfully incorporate BIM into the quantity surveying profession. 2. INTRODUCTION This assignment showcases the typical set of BIM processes from the creation of a conceptual design to tender stage. The key intention of the project assignment was set to illustrate the benefits in the Design & Planning phases of a typical construction development, with the implementation of BIM technologies and processes. The deliverable of this report is to highlight the benefits in the proper implementation of BIM into the early stages of a building lifecycle 2.1. Project Background Project L... ...onstruction. 4D Modelling is a modern approach to design and management of the building construction process. It allows effective utilization of critical resources such as labour, materials and time during the building construction life cycle. Construction projects are scheduled according to the availability of resources and depend on many external factors. As time progresses these parameters also change and hence it is important to keep a check on important activities to finish the project without any significant delays. The popular 3D building information model does not help in establishing the relationship between the schedule and sequence of construction activities to be carried out during the project execution. A 4D model incorporates time as the added 4th dimension and hence improves the quality and accuracy of the entire building life cycle management.
