Commercial Concrete Forming on the North Shore and Across Metro Vancouver

The forming subcontractor GCs and developers rely on

Cast-in-place concrete sets the datum for everything that follows. Steel, envelope, mechanical, and finishes all land on the lines and elevations we pour, so the forming package has to be right the first time and it has to be on schedule. Twin Peaks Construction works as the concrete-forming subcontractor on commercial and multi-family projects — three generations of concrete trade behind the company, operating across the North Shore and the wider Lower Mainland since 2008.

Our scope is deliberately focused: forming, rebar placement coordination, placing, and finishing structural concrete. We build to the structural engineer's drawings and the project specification, we hit the tolerances the drawings call out, and we sequence our pours to keep your critical path moving. When a general contractor hands us a package, they are handing off the part of the job that is hardest to recover from if it goes wrong — and that is exactly the part we are built for. For the exposed and feature work that often sits alongside structural concrete, see our architectural concrete capabilities.

The commercial cast-in-place scope we form

We self-perform the full structural concrete package on commercial and multi-family buildings, from the first footing to the topping slab:

• Footings and grade beams. Spread footings, strip footings, pile caps, and grade beams formed and placed to the geotechnical and structural drawings.
• Foundation and basement walls. Cast-in-place foundation walls, with blockouts, embeds, and cold-joint detailing coordinated ahead of the pour. See our note on poured concrete foundations.
• Slabs-on-grade. Industrial and commercial floor slabs with the joint layout, reinforcement, and flatness the use demands.
• Suspended slabs. Elevated structural slabs and parkade decks, formed and shored to carry the pour and the construction loads above.
• Structural walls and columns. Shear walls, core walls, bearing walls, and columns formed plumb and to size for the frame that lands on them.

On multi-family projects this often runs floor over floor on a repeating cycle; our multi-family structural experience carries directly into new concrete frames. Where waterproofing membranes or parkade traffic coatings are part of the assembly, those are coordinated with the appropriate trade — our scope is the concrete and the structure itself.

Built to the engineer's drawings, placed within tolerance

Dimensional accuracy is the whole point of a forming package. A wall that is out of plumb, a slab that misses its elevation, or a column that drifts off its grid line becomes someone else's problem on every trade that follows. We form to the lines and levels on the structural drawings and we check them before we pour, not after.

• Layout off the control. We work from the surveyed control and grid, not from the last pour, so error does not accumulate up the building.
• Embeds, blockouts, and sleeves placed first. Anchor bolts, plates, sleeves, and openings are set and tied before concrete, coordinated against the structural, mechanical, and electrical drawings.
• Rebar placement coordination. We coordinate reinforcement placement, cover, and lap to the drawings and keep it clear for inspection and the special-inspection schedule.
• Forms braced for the real load. Formwork and shoring sized for the concrete pressure and the construction loads, so nothing moves during the pour.

Building to spec also means knowing when concrete needs more than placement. For remediation and strengthening of existing structural concrete, see our structural repair work.

Schedule and the critical path

On a commercial job the concrete frame usually is the critical path, and the forming crew's cycle time sets the pace for the whole project. We plan the pour sequence with the general contractor up front so the structure comes out of the ground and climbs on a predictable rhythm.

• Pour sequencing. We lay out the forming and stripping cycle — form, reinforce, place, cure, strip, reshore, repeat — so each stage feeds the next without dead time.
• Realistic cycles. We commit to a cadence we can actually hold, floor over floor, rather than a number that collapses the first wet week.
• Coordination with the GC and inspectors. Rebar and formwork inspections, concrete testing, and the special-inspection hold points are built into the schedule, not discovered at the last minute.
• Weather-aware placement. The Lower Mainland pours through a wet, cool season; we plan cold-weather and wet-weather protection so cure times and schedule stay honest.

A forming subcontractor that gives a date it can keep is worth more than one that gives an optimistic date and misses it. We would rather tell you the real cycle at bid than explain a slip later.

Formwork, shoring, and safety

Structural concrete is built on temporary structure — formwork and shoring that has to carry wet concrete and construction loads safely until the permanent structure can stand on its own. We treat that temporary work as engineering, not improvisation.

• Engineered formwork and shoring. Wall forms, slab forms, and reshoring sized for the loads they carry, with the shoring left in place until the concrete has the strength to take over.
• Safe placement. Pump and pour planning, edge protection, and loading limits worked out before concrete arrives on site.
• WorkSafeBC and site discipline. We work to WorkSafeBC requirements and the general contractor's site safety plan, and we keep our scope tidy and inspectable.
• Clean stripping and finishing. Forms stripped at the right time to protect both the concrete and the schedule, and surfaces finished to the specified class.

Safety and accuracy are the same discipline from a different angle: forms that are braced and placed properly are the forms that come out plumb and on elevation.

Where we work and how to get a number

Twin Peaks forms commercial and multi-family concrete across the North Shore — North Vancouver and West Vancouver — and throughout Metro Vancouver and the Lower Mainland. Commercial concrete serves the wider region, and we go where the work is.

If you are a developer, general contractor, or structural engineer with a project coming up, send us the structural and architectural drawings and the schedule you are working to. We will review the forming scope, flag anything in the drawings that will affect the pour sequence or cost, and give you a clear bid for the concrete package. When you are ready, call us at (778) 882-8001 or bring us the drawing set and we will walk the structure with you.

Frequently asked questions

What is your concrete forming scope on a commercial project?

We self-perform the structural cast-in-place package: footings, grade beams, pile caps, foundation and basement walls, slabs-on-grade, suspended slabs and parkade decks, shear and bearing walls, and columns. That includes formwork and shoring, coordination of rebar placement and embeds, placing the concrete, and finishing it to the specified class. We form to the structural engineer's drawings and the project specification.

Do you work directly for general contractors and developers?

Yes. On commercial and multi-family buildings we work as the concrete-forming subcontractor to the general contractor, or directly for the developer on a design-build or construction-management job. We are used to coordinating with the structural engineer, the geotechnical requirements, the special-inspection schedule, and the other trades landing on our concrete.

How accurate is the formed concrete, and how do you hold tolerance?

We lay out off the surveyed control and grid rather than off the previous pour, so error does not accumulate up the building, and we set embeds, anchor bolts, sleeves, and blockouts before the pour and check lines and elevations before concrete goes in. We build to the tolerances the structural drawings call out, and our formwork and shoring are braced for the actual concrete pressure and construction loads so nothing moves during placement.

Can you keep up with a tight multi-family or commercial schedule?

The concrete frame is usually the critical path, so we plan the form-reinforce-place-cure-strip-reshore cycle with the general contractor up front and commit to a cadence we can actually hold floor over floor. We build the inspection hold points, concrete testing, and wet- or cold-weather protection into the schedule rather than discovering them mid-pour. We would rather bid a realistic cycle than an optimistic one we cannot keep.

Do you handle parkade waterproofing or traffic membranes?

Our scope is the concrete and the structure — forming, rebar placement coordination, placing and finishing the structural concrete, and structural concrete repair. Twin Peaks is not a building-envelope or waterproofing-membrane trade, so parkade traffic coatings and waterproofing membranes are coordinated with the appropriate specialty trade. We make sure the concrete substrate, slopes to drain, and blockouts are formed correctly for that trade to work over.
