5D BIM-Based Cost and Schedule Optimisation for a Multi-Storey RCC Building

Objective: To develop and demonstrate a BIM-integrated 5D model for optimising construction cost and schedule of a multi-storey reinforced concrete building using Indian standards.

Problem: Cost overruns and project delays are persistent challenges in the Indian construction industry, especially for multi-storey residential and commercial buildings. Inefficient planning, inadequate coordination among stakeholders, and lack of real-time cost-schedule tracking frequently affect developers, contractors, and end-users, resulting in financial losses and delayed occupancy.

Solution: This project proposes an engineering solution integrating Building Information Modelling (BIM) with 5D capabilities (3D geometry + cost + schedule) to optimise project planning, cost estimation, and timeline management for a multi-storey RCC building. The approach includes developing a parametric BIM model, linking quantity take-offs to cost data, and simulating construction sequences to identify and mitigate clashes or inefficiencies.

Key Deliverables: The project team will deliver a working BIM-based 5D prototype of a representative multi-storey building, including detailed 3D modelling (using Autodesk Revit), cost estimation (linked with DSR 2021 and CPWD rates), and schedule integration (using MS Project or Primavera). The demonstration will showcase scenario analysis, visual cost and schedule tracking, and optimisation recommendations. Students will also prepare a comprehensive report and technical paper.

Impact: This solution can enhance construction management efficiency, transparency, and stakeholder collaboration in India. The scalable methodology supports adoption in medium and large-scale projects, reducing waste, improving predictability, and supporting digital transformation in the construction sector.
