S P Sreenivas Padala Dr

M. S. Ramaiah University of Applied Sciences

Assistant Professor

Dr. S. P. Sreenivas. Padala is currently an Assistant Professor in the Department of Civil Engineering, M.S. Ramaiah University of Applied Sciences, Bangalore, India since 2020. He completed his M. Tech and Ph.D. in Construction Management from Indian Institute of Technology (IIT) Delhi. During his PhD, he worked on development of multiple-domain schedule risk model for predicting different types of changes and their impacts in Indian construction projects. Prior to his PhD, he worked in construction industry for five years in the planning and contracts department. Dr.S.P.Sreenivas Padala teaches various courses of construction management for B. Tech (Civil engineering) and M. Tech (Construction Engineering and Management) students. His research interest includes change management, project scheduling optimization, virtual design and construction (BIM), cost control, machine learning applications, and sustainable construction. Dr. Sreenivas has guided four undergraduate projects and 18 postgraduate projects in Construction Management domain. Also, four PhD students are working under him in the “virtual construction” domain. Till date, he has published 10 international journals, 9 conference articles, and 5 book chapters. Dr. S.P. Sreenivas Padala is a reviewer for International Journal of Construction Management, Taylor and Francis and Engineering Architecture Construction Management, Emerald.

 What to expect during the event

Architecture, Engineering, and Construction (AEC) projects are inherently complex, risky in nature, and difficult to manage. Due to fragmented nature of design-construction phase, every project witnessing changes throughout project lifecycle. Changes are one of the most common issues in construction projects, and they hurt project execution as far as time, cost, and quality is concerned. To manage projects successfully, it is necessary to investigate the causes of change and analyze its delays and cost overruns systematically. Past studies revealed that BIM has huge potential to minimize unnecessary delays and increase cost savings. Therefore, the objective of this study is to develop BIM-based change analysis model to analyze the changes and their impacts on the schedule and cost of construction projects.The suggested model compares the "planned" and "actual" BIM models to recognize the grouping of affected changes, taking into consideration the consequences of such presented changes on the amounts and particulars of affected structure parts and their conditions. The proposed model was applied in an ongoing office building construction project, and it was demonstrated to be very helpful in making decisions related to changes. Key benefits: (1) Changes can be identified at early stages of the design. (2) Changes in the design can be visualized and communicate better with team members (3) Documentation of change attributes, causes, its impacts in a structured manner for future reuse. (4) Contractor can apply extension of time (EOT) with ease by comparing as-planned and as-built 3D models.
