A Study on the Impact of MEP Space Organization in Large-Scale Commercial Complexes on Investment Efficiency and Its Mechanisms
This paper presents a BIM-based stochastic optimization model that integrates spatial topology analysis and Monte Carlo simulation to quantitatively reduce MEP conflicts and rework costs in large-scale commercial complexes, thereby significantly improving investment efficiency and return on investment.

Imagine you are trying to pack a giant, multi-story moving truck for a cross-country trip. You have furniture, boxes, fragile glass, and a heavy piano. If you just shove everything in randomly, the piano might crush the glass, the boxes might block the door, and you'll spend hours unpacking and repacking just to get the piano out. In the world of building massive skyscrapers and shopping malls, this "packing problem" is called MEP organization. MEP stands for Mechanical, Electrical, and Plumbing—the arteries of a building that carry air, water, electricity, and data. When these systems are crammed together without a plan, they clash, causing construction crews to rip out walls, redo pipes, and waste huge amounts of money. This paper dives into the science of how to organize these invisible systems so they fit perfectly, saving time and cash.
The researchers behind this study asked a simple but tricky question: Can we use computer simulations to figure out the best way to arrange these pipes and wires before we even break ground? They didn't just guess; they built a digital "sandbox" using a technology called BIM (Building Information Modeling). Think of BIM as a super-detailed 3D video game version of a building where every pipe and wire has a specific size, location, and job. The team used this digital model to run thousands of "what-if" scenarios, testing different layouts to see which one caused the fewest crashes and the least amount of wasted money.
Here is what they found in their study of a massive 420,000 m² commercial complex in Shenzhen. They compared the original, messy design against a new, super-organized plan. In the original design, the pipes were packed so tightly that the "density" was 7.82 meters of pipe for every square meter of floor space. It was a traffic jam of metal and plastic. The computer simulation predicted that this mess would lead to a 55.2% chance of conflicts popping up during construction, forcing the crew to do expensive rework that would eat up 9.6% of the total budget.
But when the team applied their new optimization method—essentially rearranging the equipment rooms, widening the shafts, and giving the pipes better routes—the results were like magic. The pipe density dropped to 6.44 m/m², giving the systems room to breathe. The number of "clash points" where pipes hit each other plummeted from 186 down to just 109. Most importantly, the chance of a conflict happening during construction fell to 33.8%, and the cost of fixing mistakes dropped to just 4.1%.
The study suggests that by using these computer simulations to plan the layout, the total investment loss (money wasted on conflicts and fixes) could be cut from 14.2% down to 7.6%. It's not just about saving money, though; it's also about making the building easier to fix later. The new plan made it much easier for maintenance workers to reach equipment, increasing accessibility from 78.6% to 88.3%. In the end, the researchers showed that a little bit of digital planning can turn a chaotic construction site into a smooth, efficient operation, proving that when you organize the invisible guts of a building, the whole project becomes smarter and cheaper.
