The clash detection technique using BIM facilitates early detection of construction risks such as project delays and cost overruns that may arise during execution if the clashes were not detected at design stage itself.

Numerous clashes may arise between the building elements attributed to the design demands of different disciplines which must be identified at an early design stage to avoid the risk of project delays and financial overburden [3]. In general, clash or conflict occurs when components that makes up a built asset viz., architectural, structural, electrical and plumbing systems are not spatially coordinated [4, 5, 6]. The primary causes of these clashes are design uncertainties, complexities, design errors, failing of design rules, designers working in isolation, exceedance of allowable clearance, using 2D drawings and insufficient time [7]. Two-dimensional design and lack of communication or collaboration were the major reasons for clashes [8]. Lately, clashes between different disciplines of construction projects were identified manually or by using 2D CAD tools which were both time consuming, unreliable and involves exceptional expertise [1, 7]. Clash identification was therefore a major concern in the construction projects. Majority of the clashes were identified during project execution which delayed the projects and involved schedule and cost implications. Recently, with the extensive application of BIM (Building Information Modeling), the clash detection has become easier, faster and utmost accurate reducing the project time and saving on contract value due to early clash detection [2]. BIM, a rapidly evolving collaboration tool involves creation of comprehensive and integrated master model which included design models from various disciplines [9, 10]. During the design stage, BIM enables three-dimensional visualization of clashes between independent designs for solving inter-disciplinary clashes [3, 4, 11]. Among the clash detection software available in the Architecture, Engineering and Construction (AEC) industry viz., Autodesk Navisworks Manage was the most efficient BIM based software available for detection of clashes as well as clash report generation [1, 12, 13]. Autodesk Navisworks allows users to combine 3D models; navigate around them in real-time and review the model using a set of tools [14]. This software offers Clash Detection modules that check BIM model and shows areas of interference or clash with one another. The BIM tool allows to set rules, detect clashes, generate reports, trace and manage clashes. Navisworks software specifically checks clashes between specified systems based on geometry and rule algorithms that are embedded into the BIM object [11]. Navisworks also helps in the resolution of clashes, saving on rework and material costs, and keeps projects within the budget and schedule [1, 15]. The clash detection could be performed to any level of detail and across any number of building systems. Independent models created by Architects,
