The Importance of Combine Service Drawings in Construction

Whether it's 2D or 3D BIM (Building Information Modeling), completing a Combine Service Drawing is essential before construction begins. In the past, buildings required fewer services, making the process simpler. Today, however, modern buildings incorporate a variety of services that need meticulous coordination.
In Bangladesh, many people mistakenly equate MEP Coordination Drawings with Combine Service Drawings, which can lead to significant challenges. Some architects may even believe that simply creating a Reflected Ceiling Plan (RCP) suffices. This misunderstanding complicates what should be a straightforward process.
What Should a Proper Combine Service Drawing Include?
A comprehensive Combine Service Drawing should encompass:
Additionally, all horizontal and vertical routing of these services must be included in a single drawing or model. Whether in 2D or 3D, sections should be created to identify conflicts, which must be resolved proactively. It’s critical to address not only plan-level conflicts but also any 3D issues that may arise.
Accuracy Matters
Always use actual dimensions for ducting and piping in your Combine Service Drawings. Some professionals create drawings without accurate measurements, or they list duct or pipe sizes without accounting for insulation thickness. This oversight can lead to complications down the line.

The Consequences of Neglecting Constructability
Starting work without a proper Combine Service Drawing can significantly hinder project progress. Not only does it slow down the timeline, but it also necessitates finding solutions for conflict areas, ultimately affecting the overall design and increasing costs.
A Call to Action for Professionals
I urge all professionals in the field: do not commence construction on any project without an appropriate Combine Service Drawing. Even if one is available, ensure its quality. If thorough inspections reveal inaccuracies, take the time to correct them before starting work. While this may require additional time upfront, it will save substantial time and resources in the long run.
Conclusion
Constructability is crucial for the successful execution of any construction project. By prioritizing accurate Combine Service Drawings, we can streamline processes, mitigate risks, and ensure that projects are completed efficiently and within budget.
