Caspian coordinates every mechanical and plumbing inspection on your build end-to-end — rough-in plumbing, top-out and finals, HVAC, TSSA gas piping and boiler registrations — all to Ontario Building Code (OBC). We book directly with city and TSSA inspectors, meet them on site, and walk the work so the builder doesn't lose days to missed calls or failed re-inspections. First-time pass is a discipline, not luck — and the documentation package we hand over is what gets you to occupancy and Tarion warranty registration without back-and-forth.
From the first rough-in card through final occupancy and TSSA sign-off, Caspian books the inspector, prepares the work, and stands on site with the inspector — so the GC doesn't field that call or rearrange the week around a missed window.
Supply, DWV, and venting inspected before drywall. We pressure-test in advance, walk the inspector through the riser, and have the permit card, IFC drawings, and test logs ready at the door.
Top-out after fixtures are set and trim is in. Final inspection for occupancy, including backflow devices, water meter, and fixture function — clean card, no return trip.
Ductwork, equipment clearances, combustion air, refrigerant line-set, and condensate routing reviewed against the mechanical drawings. Inspector signs the card on the first visit.
Gas piping designed and installed to B149.1, pressure-tested on ambient, witnessed and signed by the TSSA-registered tech. Certificates filed with TSSA and copied to the project file.
CRN verification, boiler registration with TSSA, and pressure vessel paperwork for hydronic and combi systems. Filed before commissioning so there's no occupancy hold.
Full handover binder: inspection certificates, test sign-offs, as-builts, O&M manuals, and warranty registrations — ready for the city's occupancy clearance and Tarion enrolment.
A failed inspection costs the builder a week — sometimes two. We don't rely on "the inspector liked it." We run a process that makes the first visit the only visit.
01 — Self-inspection first
Self-inspection before the inspector arrives — we walk the rough-in with a checklist matched to the inspector's actual review pattern. If anything is off, it's corrected before the booking, not after.
02 — Photo documentation
Photos of every joint, every connection, every test point — kept in the project file in case of post-completion question. Nothing gets buried behind drywall without a photo in the binder.
03 — Pressure tests on the record
Pressure tests documented and signed off — air on water lines, smoke on DWV, ambient on gas. Test logs are stapled to the permit set and shown to the inspector before they ask.
04 — Inspector relationships
Inspector relationships — we don't avoid them, we coordinate. The inspector knows what to expect and so do we — same crew, same documentation, same standard, every visit. That's why they sign the card the first time.
The inspection card is the start, not the finish. The builder needs a complete documentation package to clear occupancy and register Tarion warranty — Caspian assembles it as we go so nothing is reconstructed at the end.
City permit cards closed out and signed, TSSA gas and boiler certificates where applicable — originals to the builder, copies in the binder, scans in the project file.
Water supply, DWV, and gas test logs — pressure, duration, witness, date — signed by the licensed tech who ran the test. Ready for any audit, ever.
Red-line as-builts capturing any rough-in changes from the IFC set — riser routing, fixture relocations, mechanical room layout — so the owner and the next trade aren't guessing.
Manufacturer O&M manuals for every piece of equipment, plus warranty registrations filed in the homeowner's name — boiler, water heater, furnace, AC, all logged for Tarion.
