Portable envelope production

Move the envelope
off the critical path.

BRYTEK turns wall panels into installation-ready envelope assemblies in a portable production system—bringing factory control to the project, without moving the project to a factory.

THE COMMERCIAL THESIS
4–6
months targeted
schedule reduction

By completing envelope work while the structure is still being assembled.

THE JOBSITE ISN'T THE PROBLEM.

The sequence is.

Exterior work usually begins after framing. BRYTEK starts it before installation—turning a serial schedule into a parallel one.

FROM THE FIELD / 00:40

BRYTEK in the field.

Real panels. Real installation.
Watch the work take shape.

01 / THE SYSTEM

A factory that travels
to the project.

A compact, transportable production line processes vertical wall panels close to the site. Each step is visible, repeatable and designed around how the building will actually be assembled.

POS.01

Wall panels enter vertically

Panels arrive from the framing line and move directly into a controlled, upright production flow.

Conceptual process illustration. Future automation is shown for context; the roadmap below distinguishes current work from planned capabilities.

02 / THE IMPACT

Run the work
in parallel.

BRYTEK is built around one operational change: start the building envelope while framing is still moving—not months after it begins.

Original BRYTEK Gantt chart. Conventional practice totals 50 weeks (350 days): framing 60 days, framing inspection gate, envelope preparation and window installation 16 weeks, watertight and airtight work 16 weeks, mid-construction air test, rainscreen 24 weeks, exterior finishing 30 weeks. BRYTEK totals 29 weeks (203 days): framing 60 days, envelope prefabrication 10 days, window sill preparation 10 days, window installation 10 days, rainscreen 8 weeks, mid-construction air test, exterior finishing 12 weeks. Activities overlap as shown; durations are not additive.

OUR ORIGINS / 330 GOLDSTREAM AVENUE

Where it
all began.

BRYTEK traces its roots to the envelope work at 330 Goldstream Avenue in Colwood. Before the portable production cell, there was a real project—and the practical challenge of moving envelope work earlier.

  1. 2019 / RESEQUENCING THE WORK

    Bring the envelope into the production line.

    BC Housing documents Brytar Contracting working with Kinetic Construction and the prefabrication team. At ZyTech’s yard, panels were inspected, Brytar applied the sheathing membrane, and assemblies were repacked in installation order. The work moved upstream, before delivery to site.

  2. JUNE 2020 / FIRST AIR TEST

    Measure the envelope.

    The envelope substantial-completion test achieved 0.44 ACH50 against a 0.60 target. The result established a measured performance milestone before exterior insulation and cladding proceeded.

  3. MARCH 2021 / FINAL VERIFICATION

    Test the finished building.

    The final blower-door test recorded 0.55 ACH50, still below the project’s 0.60 target. This was a whole-building result delivered by the coordinated project team.

  4. THE NEXT CHAPTER / BRYTEK

    Make the process portable.

    BRYTEK’s direction builds on that experience: bring controlled envelope production closer to the project, integrate windows and quality records, then develop automation around a repeatable workflow.

The lessons mattered as much as the result.

Bulletin 4 also records weather exposure, transport and storage constraints, and panel-alignment issues requiring repairs. It stresses early coordination and quality control. These challenges help explain BRYTEK’s focus on near-site production and verification.

The BC Housing bulletins document the Goldstream project and Brytar’s contribution; the connection to BRYTEK is our company’s development story. These publications do not establish BC Housing endorsement of BRYTEK or validate its current schedule-reduction targets.

03 / THE PLATFORM

Prove the process.
Then automate it.

The manual system creates value immediately. Computer vision and robotics build on a process that has already been designed, timed and tested in the field.

Manual production

A transportable line that standardizes envelope and window work near the jobsite.

POS 1.0

Computer vision verifies geometry, installation and workmanship as every panel moves through.

Robotic application

Automate membrane application to increase output while preserving a repeatable quality standard.

THE PRODUCT BEHIND THE PRODUCT

Every panel leaves with a quality record.

Images, dimensions, tolerances and installation evidence become one structured file—from factory position to building position.
