Risk Analysis and Mitigation in PEB Warehouse Construction Projects: A Case Study Approach Irene Mary Alias1, Anitha2 Post Graduate Student, Faculty of Architecture, Dr. M.G.R. Educational and Research Institute. Chennai, India Associate Architect, Faculty of Architecture, Dr. M.G.R. Educational and Research Institute. Chennai, India ---------------------------------------------------------------------***--------------------------------------------------------------------1.2 Objectives Abstract - With unique advances in structural capacity, expediency of construction and minimal cost, pre-engineered buildings (PEBs) have brought about a revolution in the warehouse market across India. Although these merits, the prospects have involved of the risk concerns in the PEB warehouse project which may result in the negative impact on the cost, duration and quality of the project completion. In this paper, the kinds of risk factors, their effects and the preventive actions of PEB warehouse construction are examined empirically. A detailed mixed-methods methodology was used combining literature review, practical and international case studies plus online questionnaires towards industry practitioners. Matrix was used for identification, classification, and prioritization of risks, as well as measures for the mitigation of potential risks. Results show that failure of the equipment, delay in procurement, lack of manpower resource and lack of financial planning are major challenges faced. The pragmatic suggestions outlined in this study will serve as a useful tool for PM, engineers and policymakers to enhance risk management strategies suitable for Indian PEB construction practices.
1.INTRODUCTION Pre-engineered buildings (PEBs) with the features of cheaper cost, flexible design, and fast construction is increasingly being used in warehouse building applications. Being similar to any other construction work, PEB warehouses are exposed to various types of risks in terms of design risk, material procurement delays, labour shortage, site level risks, productivity inefficiencies. These risks however are compounded in the Indian construction sector by peculiar logistical, financial, and legal challenges which are found especially in major cities like Chennai.
Examine current risk mitigation strategies and suggest more effective new ones.

Pre-engineered building (PEB) is a modern concept of utilizing sustainable steel structures and can be compared with conventional steel building (CSB) which is analogous to compare wooden furniture with light wooden furniture. They are lighter (10–20% less) and quicker to erect (usually 6–8 weeks) because they are fabricated from prefabricated, tapered sections which are bolted together on-site. By comparison, CSBs take 20–26 weeks to be manufactured, involve considerable in-situ fabrication and are reliant on the use of hot-rolled sections. PEBs also enjoy the advantages of single-source responsibility that reduces coordination errors, provides for easier expansion, and is
To holistically investigate the risks, to assess their significance, and to generate risk mitigation strategies for evaluating and improving risk-management systems for PEB warehouse construction.
