Cost-Effective Bim Integration For Pre-Engineered Buildings

Abstract

Pre-engineered buildings (PEBs) revolutionized industrial construction via efficient manufacturing and speedy 
erection; however, their design optimization and cost-efficiency potential is underutilised at a moment in time 
powered by advanced Building Information Modelling (BIM) platforms with structural analysis software. The 
solution proposed in this empirical study is quantitative proved as a direct consequence of introducing BIM 
workflows (via Autodesk Revit and Tekla Structures) with Finite Element Analysis Tools, such as STAAD. 
Design simulations using Pro and SAP2000 along with four independent PEB case studies on a factory, 
warehouse, car showroom and sports hall providing clear spans from 15 m to 40m respectively at Central 
India. The average structural weight reduction, total project cost savings and construction schedule 
compression compared to conventional steel frame alternatives are respectively 25.6%, 27.2% and 
41.9%(based on data collected from a database of fifty representative structural simulations, including six 
corresponding beneficial Project Documentation records + Cost audits covering ₹625 lakh in combined 
construction expenditure). Clash detection through BIM cut down design conflicts by 87.7% and Requests for 
Information (RFIs) by an astounding 86.0%. Building type, span length, and software platform are all shown to 
significantly affect cost savings according to ANOVA (p < 0.01). It yields an R² of 0.986 for the deflection-span 
relationships, validating design reliability via regression modelling The results clearly indicate that BIM
Integrated design of PEB is a robust, scalable method for economical and structure optimized construction in 
Indian industrial and commercial building typologies.
