BIM-LPS® Integration Case Study in the MEP Sector: Automating Phase Schedule Generation

Abstract –
The Last Planner System® (LPS®) and Building Information
Modeling (BIM) hold strong potential to improve
construction productivity, yet their integration at the dataprocessing
level remains limited. Information embedded in
BIM models is often insufficiently structured and therefore
not directly exploitable for LPS® implementation. This study
proposes an approach that integrates LPS® with BIM while
leveraging multiple sources of operational project data to automate
phase planning. The work focuses on the mechanical,
electrical, and plumbing (MEP) domain, which is particularly
complex and has been less explored in prior research.
A digital tool was developed to automatically generate
time–location schedules by combining tender-phase estimates,
execution-phase BIM models, client-defined milestones,
and expert knowledge of MEP work sequencing. System
requirements were defined through a literature review
and surveys with MEP professionals. Installation operations
were standardized, and the solution was implemented as a
three-tier web application supporting automated data extraction,
processing, and visualization for project planning,
using tools such as Dynamo Revit, MySQL, Java, and Angular.
Validation on a real project demonstrated clear benefits:
the time required for initial planning is reduced by up to
one week compared with traditional methods. In addition,
automated schedule generation and updates yield a financial
gain of 0.91% of project revenue – equivalent to nearly 30%
of the planned profit margin – highlighting both the practical
