BIM Constructability Review Services

01 — The Challenge

A BIM model can be technically coordinated and still present challenges during actual construction.

Common issues include:

• Systems that technically fit but cannot be practically installed

• Insufficient access or maintenance clearances

• Difficult equipment replacement routes

• Inadequate space for installation and assembly

• Structural openings not aligned with service requirements

• Congested plant rooms and service corridors

• Difficult duct, pipe, or cable tray installation sequences

• Uncoordinated equipment access and lifting requirements

• Installation conflicts discovered after materials reach site

• Design solutions that are difficult or expensive to construct

• Temporary works and construction sequencing not considered

• Rework caused by poor design-to-construction coordination

VDEC reviews the BIM model from the perspective of the people who will actually build, install, access, and maintain the asset.

02 — VDEC Solution

Our BIM Constructability Review combines multidisciplinary coordination with construction-focused engineering review.

We evaluate the model for:

Spatial Constructability

• Available installation space

• Ceiling and service-zone constraints

• Plant room layouts

• Shaft and riser coordination

• Equipment clearances

Installation Feasibility

• Equipment installation requirements

• Duct and pipe routing

• Cable tray installation

• Component assembly

• Access for tools and workers

Maintenance & Access

• Equipment maintenance zones

• Valve and damper access

• Electrical panel access

• Filter replacement areas

• Equipment removal and replacement routes

Structural & Building Interfaces

• Openings and penetrations

• Sleeves and embeds

• Structural clearances

• Equipment supports

• Access requirements

Construction Planning

• Installation sequencing

• Material movement

• Prefabrication opportunities

• Site installation constraints

• Temporary access requirements

Our goal is to identify buildability risks while changes are still practical and economical to make.

04 — Our Process

01. Project & Construction Strategy Review

We review project requirements, construction methodology, BIM Execution Plan, project schedule, design information, and available construction planning information.

02. Model Collection & Validation

The latest Architectural, Structural, MEPF, and specialist models are collected and reviewed for completeness, coordination, and suitability for constructability assessment.

03. High-Risk Area Identification

We identify areas where construction complexity or coordination risk is likely to be highest, including plant rooms, shafts, service corridors, ceiling spaces, structural interfaces, and congested zones.

04. Spatial & Installation Review

Our team evaluates whether equipment, ducts, pipes, cable trays, and other building components can be practically installed within the available space.

05. Access & Maintenance Review

We assess access requirements for installation, inspection, operation, maintenance, repair, and future equipment replacement.

06. Construction Sequence Review

Where required, we evaluate the logical sequence of installation and identify potential constraints related to access, material movement, assembly, and sequencing.

07. Issue Classification & Recommendations

Identified issues are categorized according to priority and construction impact, with practical recommendations provided for resolution.

08. Coordination & Resolution

Issues are coordinated with the relevant design and construction teams, and updated models are reviewed to confirm that critical constructability concerns have been addressed.

09. Final Validation

A final BIM-based constructability review is performed to verify that the coordinated design is practical and ready for the next stage of construction.

05 — Software & Technology

Our constructability teams use industry-standard BIM and coordination technologies, including:

Autodesk Revit | Navisworks | AutoCAD | Autodesk Construction Cloud (ACC) | BIM 360

Where applicable, we also work with 4D planning information, project-specific BIM standards, construction methodologies, coordination matrices, and Common Data Environments.

06 — Benefits

Buildability Before Construction

Evaluate whether the design can realistically be built before resources are committed on site.

Reduce Rework

Identify construction problems during the design and coordination stage rather than after installation begins.

Improve Installation Planning

Understand how equipment, services, and components can be installed within the available space.

Identify Access Constraints

Review access for installation, operation, maintenance, repair, and replacement.

Reduce Construction Risk

Identify high-risk construction areas early and develop mitigation strategies.

Improve Coordination

Connect design coordination with practical construction requirements.

Optimize Plant Rooms & Service Zones

Improve the use of congested spaces by evaluating routing, access, equipment arrangement, and installation requirements.

Support Prefabrication

Identify systems and assemblies that may benefit from prefabrication and modular construction approaches.

Improve Project Predictability

Address potential construction constraints before they cause delays, redesign, or additional cost.

Better Construction Documentation

Provide coordinated information that supports shop drawings, installation planning, and site execution.

07 — Example Project

BIM Constructability Review for a High-Rise Commercial Development

Project Type: High-Rise Commercial / Mixed-Use Development
Scope: Multidisciplinary BIM Coordination + Constructability Review
Disciplines: Architecture + Structure + HVAC + Electrical + Plumbing + Fire Protection
LOD: 350

VDEC Approach

VDEC performed a construction-focused BIM review after completing multidisciplinary coordination.

The review concentrated on plant rooms, vertical shafts, congested ceiling zones, service corridors, equipment access areas, structural penetrations, and major MEPF routes.

Beyond identifying physical clashes, the team assessed whether equipment could be installed, whether maintenance access was available, whether services could be practically routed, and whether construction teams could execute the proposed solutions efficiently.

High-risk issues were documented with BIM views, locations, priorities, and recommended solutions.

Outcome

The project team gained greater visibility into construction and installation risks before site execution, enabling design improvements, better coordination, and more practical construction planning.

08 — Don't Just Coordinate. Make It Buildable.

A clash-free BIM model is only the beginning.

A truly effective BIM model should help answer a more important question:

“Can we actually build it?”

VDEC combines BIM coordination, engineering knowledge, and construction-focused review to identify potential buildability issues before they become site problems.

From installation feasibility and access reviews to plant room optimization, sequencing, and multidisciplinary constructability, we help turn coordinated designs into practical construction solutions.
