BUILDERS · PRE-CONSTRUCTION CONSULTING

Pre-construction consulting — catch the costly stuff before it's built.

Caspian works alongside your architect and structural engineer during design — reviewing mechanical drawings against constructability and the Ontario Building Code, proposing value-engineering alternates with real numbers, reconciling the consultant's budget against current GTA market pricing, and sizing the mechanical room with the access and clearances trades actually need. Riser routing, stack pathing, beam clashes, hidden conflicts — we flag them on paper while they're still cheap to fix, not after the framing is up.

WHAT WE REVIEW

The full pre-construction scope.

We sit between the design team and the field — pressure-testing the mechanical package against constructability, code, and current market pricing before it gets tendered. One licensed mechanical contractor with two decades of GTA install experience reading the drawings the same way the foreman will.

Mechanical drawings

Line-by-line review of plumbing, HVAC, and hydronic drawings. We read every page against constructability, sequencing with other trades, and how the work will actually get built in the field.

Mechanical room sizing + access

Equipment footprints, service clearances, removal pathways for future replacement, and door-swing checks. Most rooms we review are too small once you account for code-required clearances and the access trades need to actually service the equipment.

Riser + stack routing through structure

We trace every plumbing riser and ventilation stack through the structural drawings — flagging beam clashes, missing sleeves, and bulkhead conflicts before concrete is placed or framing is up.

Code-compliance review (OBC + bylaws)

Drawings cross-checked against the Ontario Building Code, the local plumbing bylaw, and any AHJ-specific amendments. We flag deviations before the consultant stamps the IFC set.

Value engineering proposals

Alternate systems and equipment with side-by-side capital cost, lifecycle cost, and schedule impact. Real numbers from current GTA suppliers — not theoretical savings that disappear at procurement.

Budget reconciliation vs consultant estimate

Your consultant's mechanical budget benchmarked against what the trade will actually bid today. Where the estimate is light, we tell you — with the line items and the reason — before the tender comes back over budget.

WHEN TO BRING US IN (AND WHY EARLY IS CHEAPER)

Design phase = cheapest fixes.

The same fix costs 10× more in the field than it does on a drawing. Here's the rough math on where in the design lifecycle we add the most value — and where we can still help even if you're already mid-build.

01 — Best

Schematic design.

The best time to engage. Mechanical room sizing, riser routing, and access issues can still be moved with the stroke of a pen — before they're cast in concrete or boxed in by structural steel. This is where pre-construction consulting pays back 10-to-1.

02 — Acceptable

Design-development phase.

Still acceptable. We review the consultant's drawings before tender, flag constructability conflicts and value-engineering opportunities, and propose alternates while the equipment schedule is still open. Most builders catch enough savings here to fund the review three times over.

03 — Late but useful

Post-tender pre-construction.

Late but still useful. We review the awarded subcontractor's submittals and shop drawings against the IFC set — catching equipment substitutions, undersized risers, and missing scope before they show up as change orders during rough-in.

04 — Too late

Framing already up.

Too late for cheap fixes. Now it's drywall, structural changes, or added scope to make the mechanical work. Costs run 3–10× more than catching the same issue during design — and the schedule almost always slips with it. Engage us next time before the shovel.

WHAT YOU GET FROM US

Written deliverables, not a conversation.

Every engagement ends with a PDF the design team can act on — not a phone call you'll forget by Monday. Four documents, distributed-ready.

Written review with annotated drawings

PDF package — your consultant's drawings marked up with conflicts, code flags, and recommendations, plus an executive summary. Ready for distribution to the architect, structural engineer, and mechanical consultant the day we deliver it.

Constructability + access notes

Mechanical room layout review, ductwork pathing recommendations, service clearances, and removal pathways. Where the design will be hard to install or impossible to maintain — and how to fix it on paper.

Value engineering proposals

Alternate systems and equipment options laid out with capital cost, lifecycle cost, and any schedule or scope impact. You see the trade-offs clearly, in numbers — not a hand-wave that the boiler can be cheaper.

Budget reconciliation

Your consultant's mechanical estimate reconciled line-by-line against current GTA market pricing — equipment, labour, and material. You learn where the budget is light before tender, not after.
