BIM · VDC Coordination — Burnaby, BC

Bridging the gap from design to site.

Raha Design builds coordinated, construction-ready BIM models so developers, trades and consultants build with certainty — resolving clashes, protecting margin and eliminating rework before a single piece is installed.

راها · Raha — Persian: unbound, free of restraint.

The problem we remove

Most cost overruns are designed in, not built in.

On site, an unseen clash becomes an RFI, then a change order, then a stopped crew. We move that discovery upstream — into one coordinated model everyone shares — so the field focuses on execution instead of interpreting drawings, and surprises surface before they cost money.

Fewer RFIs & change orders

Clashes and scope gaps are caught and resolved in the model, not in the field.

Protected profit margin

Value engineering and less rework keep budgets and schedules where they belong.

One source of truth

A single, unified model — and every 2D sheet drawn from it — for the whole team.

Capabilities

A model that carries the whole project — from geometry to handover.

Every service below runs off one coordinated model. Start with the level of detail you need, then layer scheduling, cost, immersive review and as-built records on top.

LOD 300

Detailed Design

Recommended for consultants. Geometry, specific sizes and detailed components — ready for construction documents and discipline coordination.

LOD 350

Construction Coordination

Recommended for developers, owners and GCs. Adds construction-level information for generating documents and shop drawings.

LOD 400

Fabrication & Assembly

Recommended for trades and modular. Detailed assemblies and connections, suitable for fabrication and installation.

Coordination process

Six layers of clash detection.

There's no such thing as perfection in construction — so instead of one perfect pass, we run several layered stages. Software plus human review, each layer a fresh chance to catch what the last one missed.

Modeled on a rainscreen wall assembly — layered, redundant, resilient.

Soft clashes

Resolved in-house, documented, approved

Clashes that don't need engineering input are solved against a checklist agreed with your design team at the outset — always aligned with design intent. Every resolution is documented and returned for approval, like a shop-drawing review. Fewer RFIs, fewer meetings.

Hard clashes

Flagged, visualized, escalated

Clashes that need engineering calculations or multiple consultants — because they affect several scopes or systems — are documented with supporting visuals and escalated to the responsible consultant. You never leave a coordination meeting without answers or options.

Who we serve

Tailored to your seat at the table.

The same coordinated model, scoped and delivered differently depending on where you sit in the project. Choose your role.

Why Raha

Coordination that thinks like the field.

Most trades are too busy — or unwilling — to risk proposing alternatives to what's drawn. So developers and GCs absorb avoidable costs without realizing it. We close that gap.

01 · Our key differentiator

MEP foremen in the model

We bring experienced MEP foremen into the modeling process on an ad-hoc basis to bridge the gap between design and site — ensuring constructability in advance and recommending optimizations that bring cost efficiency, improve MEP performance, and eliminate avoidable RFIs, change orders and coordination delays during construction.

We resolve, not just flag

We don't just find and flag clashes — we solve them for you, to your design criteria, and document every fix. You get answers and options, not a list of problems.

Defense in depth

Six layered clash-detection passes — automated software and human review — so nothing slips through to the field. If one layer misses it, the next one catches it.

One cloud portal

Design and construction teams navigate the model and review clashes in real time, in one place — eliminating the version-control chaos of static PDF exchanges.

Useful after handover

Your as-built digital twin keeps serving property management and owners for the life of the building — an accurate record for operations, maintenance and future renovations.
