Clash Detection & Model Coordination

CMS Surveyors combines survey verified BIM models, point cloud data and model coordination workflows to help project teams identify clashes early, reduce RFIs, minimise rework and make confident decisions before construction begins.

Coordinate designs against real site conditions

Clash detection gives your project team confidence that models have been coordinated before construction begins, reducing risk, delays and unnecessary redesign.

Find coordination issues before they
become site problems.

Clash detection is most valuable when it is practical, visual and grounded in accurate site information. CMS
helps teams coordinate design intent with the real built environment.

Architectural, structural, civil, hydraulic, mechanical and electrical models are often developed independently. Without clash detection, teams often discover conflicts only after construction has begun, resulting in redesign, delays and expensive site changes.

CMS Surveyors identifies these issues before they become construction problems.

What we help to coordinate

Clash Detection identifies these issues early – allowing project teams to resolve them digitally instead of on site.

Structure and Architecture

Columns, beams, slabs, roof framing, penetrations, opening and interfaces between architectural and structural elements.

Structural Coordination

HVAC, hydraulic, electrical, fire services, communications, plant rooms, corridors and ceiling void congestion.

MEP Coordination

Point cloud, scan-to-BIM and survey data overlays to check design information against existing conditions.

Visual reporting that’s easy to understand

A strong clash detection report should sow what is clashing, where it is located, which disciplines are involved and what action is required next. This helps the project team resolve issues digitally before they become delays, RFIs, redesign work or site rework.

Clear issue types for practical action.

We separate clashes into meaningful categories so the project team can prioritise the issues that matter most.

Hard Clashes

Physical intersections between elements, such as a service route passing through structure.

Clearance Clashes

Access, maintenance, or installation clearances not maintained around services or equipment.

Model-to-reality Clashes

Access, maintenance, or installation clearances not maintained around services or equipment.

Sequencing risks

Issues that may affect installation order, trade access or construction workflow.

Deliverables tailored to your project.

A clean workflow from data to decision.

Successful model coordination is about more than running clash detection software. Our experienced BIM team follows a structured process to align, review, prioritise and report issues clearly.

Whether you’re coordinating a commercial building, infrastructure project or complex services installation, we deliver practical outputs that keep construction moving forward.

1. Receive project data

We review design models, CAD files, survey data, point clouds and project-specific coordination requirements.

2. Federate and align

Models and existing condition information are aligned into a coordinated review environment.

3. Detect and prioritise

We identify hard clashes, clearance issues, model-to-reality conflicts and high-risk coordination zones.

4. Report and support

Your team receives clear reports, views and practical information to support design decisions and reduce rework.

Our Clients

Our clients include government bodies, architects, planners, builders, developers and engineers, as well as solicitors, real estate agents and individual property owners.

Frequently asked questions

The cost of undetected clashes

Most construction delays dont begin on site. They begin months earlier, when isolated design models don’t align.

Undetected clashes can result in:

Site rework
RFIs
Program delays
RFIs
Trade conflicts
Design revisions
Material waste
Budget overruns
Reduced productivity
Client variations

Resolving a clash during design costs significantly less than discovering it during construction.
