A data center coordination model can be free of obvious clashes and still create problems in the field. For example, a route may fit geometrically but leave no room to install a support, pull a cable, open an equipment door, or perform maintenance.
In data centers, dense electrical and mechanical systems, redundant pathways, and limited spatial flexibility make it especially crucial to evaluate not only whether systems fit, but whether they can be built and operate as intended.
Hexagon Multivista supports this work through Create services, including VDC management and 3D modeling and 2D drafting, that help project teams move from coordinated geometry to field-ready information.
Constructability begins where clash detection stops
Clash detection identifies physical conflicts and clearance issues between modeled elements. Constructability looks at a broader question: can the coordinated design be installed safely, practically, and logically under real project conditions?
As Damián Pavón, Electrical Program Manager and VDC Coordinator at Hexagon Multivista, explains, “A model needs more than clear geometry. Safety and service clearances must be modeled so panels can open safely, cables can be pulled, and technicians can maintain equipment without hazard.”
That is especially relevant for MEP subcontractors, whose coordinated models need to support installation decisions rather than simply produce a clean clash report. Hexagon Multivista services for MEP subcontractors connect coordinated BIM support with the site and installation information needed to help teams manage complex building systems.
Clearances turn empty space into coordinated space
Clearance zones are spaces that may look empty in the model but are functionally required.
Around electrical equipment, that can include door swings, cable entry, service access, and code-mandated electrical working clearance for operation and maintenance. Cable trays may also need space for supports, cable pulling, thermal dissipation, and minimum bending radii. If those requirements are not represented during coordination, one system can occupy space that another trade needs later on in the build.
This is where VDC management moves beyond basic model review. By coordinating architectural, structural, and MEP information together, teams can evaluate routing, access, clearances, and installation logic before those decisions reach the field. Hexagon Multivista VDC management services specifically include multidisciplinary model coordination, structured clash detection, constructability reviews, and installation reviews.
A clearance violation, often flagged as a soft clash, can be just as critical as a physical hard clash.
Field knowledge keeps coordination grounded
Constructability also depends on knowledge that is not always visible in the model.
Modelers and coordinators may understand the geometry and project requirements, but field teams bring practical knowledge of how components are handled, supported, connected, and installed. That input can be especially valuable when a routing option or support arrangement is technically possible but difficult to execute.
That field input helps answer questions that cannot always be resolved from the model alone. As Damián explains, “Modelers are not always on site, so certain field realities are harder to know. That is why we ask the people who actually install the work, ‘Can this be built this way in the field?’”
BIM coordination services are stronger when that question is part of the process. Constructability review connects the coordination model with installation experience, giving teams another opportunity to resolve uncertainty before work advances.
Installation sequence is part of constructability
A buildable solution also needs to account for sequence.
Data center systems often occupy the same limited areas at different elevations and stages of installation. A route that works in the final model may still create a problem if one trade cannot install its scope after another system is already in place.
That means coordination needs to consider anchor points, trapeze hanger installation, equipment rigging sequences, and cable pulling pathways.
Hexagon Multivista 3D modeling and 2D drafting services can support project-specific coordination, fabrication, and documentation needs so models and drawings provide usable information as work moves toward construction. The service includes constructability and fabrication modeling intended to support trade coordination, clash detection, subsequent construction, and field installation.
Small changes can create cascading impacts
Constructability becomes more difficult when project information changes.
Underground electrical infrastructure is a clear example. Data center sites can include multiple duct banks serving different voltage levels and telecommunications systems. Their elevations and routing must account for finished grade, roads, foundations, utilities, and required separation.
Damián explains, “If one duct bank has to shift down, the routes below it may have to move too. That can create a cascading effect of physical clashes and clearance violations.”
This is why data center coordination needs to manage change and geometry. A seemingly localized revision can affect several systems, drawings, supports, and installation decisions if the consequences are not reviewed across the coordinated model.
Coordination should lead to field-ready decisions
The purpose of coordination is not simply to reduce the number of clashes reported by software. It is to help project teams reach decisions that can be executed in the field.
For data center projects, that means considering geometry together with clearances, access, supports, installation sequence, equipment requirements, and changing project information. Hexagon Multivista data center solutions connect these coordination needs with Create services designed to support high-density MEP systems, constructability, and multidisciplinary alignment throughout data center construction.
When BIM coordination services and constructability review are connected, teams can address more of those questions before installation begins and reduce the risk of discovering that a coordinated route cannot actually be built.
