ALDA Building Systems delivers fully coordinated mechanical, electrical, plumbing, fire protection and low-voltage systems for commercial, industrial, institutional and residential projects across Ontario.
Our integrated approach brings building systems together before they reach the site. Each discipline is modeled, coordinated and clash-checked in 3D prior to installation, helping reduce conflicts, rework and schedule disruption during construction.
Clients can engage ALDA for a complete building systems package under one contract and one coordinated schedule, or for individual systems and specialized services as required.
Two ways to work with us
Some clients hand us every system from scan to closeout. Others need one system or service on a project they're already running. Both get the same team, the same tools and the same standard.
Option 01
Mechanical, electrical, plumbing, fire safety and low-voltage under one contract. Scanned, modeled, coordinated, installed and closed out by one team.
Option 02
Hire us for any single system or service on your project, alongside your own trades and consultants.
Individual systems
Coordination & investigation
From model to building
Every duct, pipe, tray and sprinkler is placed in the model before anyone is on site. What gets installed is what was coordinated.
From our models
Every project starts here. Structure, ductwork, piping and risers modeled together, checked for clashes, and resolved before a single hanger goes in.
Systems we deliver
Each colour in our name is a trade you'd normally hire, schedule and chase separately. We bring them under one scope and coordinate them before anyone arrives on site.
Heating, cooling, ventilation and gas, sized to the space and installed to the coordinated drawings.
Power from the service entrance to the last device, plus the low-voltage systems and EV charging built on top of it.
Sprinklers, standpipes and alarm devices, coordinated with the rest of the ceiling space from day one.
Everything from the fixtures back to the municipal connection, including the excavation to get there. We locate and inspect before we dig.
Sectors
Every building type puts different demands on its systems. We work across commercial, industrial, institutional and residential projects, and plan each one around the rules and pressures of its sector.
Business & mercantile
Offices, retail and hospitality spaces where the systems have to work around tenants, landlords and opening dates.
What matters hereLandlord criteria, fast turnovers and work in occupied buildings.
Industrial
Warehouses and production spaces where power, air and water have to keep up with the equipment.
What matters hereService capacity, storage sprinkler requirements and uptime during upgrades.
Assembly & care
Schools, healthcare, community and faith buildings that stay open while the work happens around them.
What matters herePhased schedules, life-safety systems and full compliance documentation.
Residential
Custom homes, multiplexes and garden suites, where every system has to fit a tighter footprint.
What matters hereService sizing for added units, fire separations and sprinkler or fire access requirements.
Codes refer to Ontario Building Code major occupancy groups.
Drawing coordination
We model the mechanical, electrical, plumbing and fire systems in 3D, run clash detection, and issue coordinated drawing packages that trades can install from. Every clash we resolve in our office is rework, wasted material and site time you don't pay for later.
Every ALDA systems package is coordinated before we mobilize.
Coordinated drawing packages and as-builts for projects that need them.
| ID | Systems | Grid | Status |
|---|---|---|---|
| C-014 | SA duct / SPR main | C–D / 4 | Resolved |
| C-015 | SAN 100 / Beam W310 | D / 4–5 | Resolved |
| C-016 | Cable tray / RA duct | D–E / 5 | In review |
| C-017 | SPR branch / Light fixture | E / 5 | Open |
The same conflict between a duct and a sprinkler main can be a two-minute fix or a week of rework. The only difference is when someone catches it.
In our model
Move a line, re-run the check, reissue the drawing. No material, no site time.
In shop drawings
Drawings go back for resubmission and approvals slip while trades wait.
During install
Material is cut out and scrapped, crews stand down, and change orders start.
After ceilings close
Finished work gets opened up, re-inspected and patched, and handover moves back.
Conflicts are priced out before the contract, not argued about during it.
Material is ordered and cut once, to a layout that's already been checked.
Trades install in sequence, inspections pass the first time, and ceilings close on the planned date.
Coordination results
Design drawings from separate consultants rarely agree with each other. We model every discipline together, log every conflict, and resolve it with the design team before tender. These are the totals across our team's coordinated projects.
Where the savings come from
How we estimate savings. Rework is priced as the labour, material, demolition and re-inspection a clash would have caused if found during installation. Change orders are counted only where a conflict would have become a paid change. Schedule savings use days recovered multiplied by actual daily site costs. Consultant fees avoided cover the additional-service charges for bringing engineers and architects back to redesign, answer RFIs, revise and reissue drawings, and attend site reviews. We use conservative rates and never count design-stage fixes the consultant would have made anyway.
Investigative services
Existing buildings and sites hide things. Before we price or open anything up, we locate, scan and document what's already there, so the number you get reflects the building you actually have. Every service is available on its own.
GPR and electromagnetic locating of buried water, sewer, gas and electrical lines on private property before trenching or excavation.
Deliverable: Marked site, locate sketch
Camera runs through drains and sewer laterals to find breaks, roots and sags before we dig.
Deliverable: Recorded video, located defects
Smoke and dye testing, leak detection and lateral tracing to find where water is going and where it shouldn't be.
Deliverable: Traced routes, leak locations
Static and residual pressure and flow readings from nearby hydrants, to confirm the water supply available for sprinkler and fire service design.
Deliverable: Flow test report, supply curve
Testing of backflow preventers by a certified tester, so your devices stay compliant and your municipal filings stay current.
Deliverable: Test report, municipal submission
GPR scanning of slabs and walls to locate rebar, post-tension cables and conduit before coring or cutting.
Deliverable: Marked layout, scan report
Point-cloud capture of existing spaces, ceilings and mechanical rooms, accurate enough to model and coordinate against.
Deliverable: Point cloud, as-built model
Roof and site capture for rooftop equipment, service routing and progress documentation.
Deliverable: Aerial imagery, roof equipment layout
Infrared scans of electrical panels, hydronic lines, roofs and building envelope to find hot spots, leaks and heat loss.
Deliverable: Thermal images, findings report
A walkthrough of existing mechanical, electrical, plumbing and fire systems, with age, condition and what needs attention.
Deliverable: Written report, priority list
Building systems review before you buy or lease, so replacement costs show up in the deal instead of after it.
Deliverable: Findings, budget-level cost ranges
How we work
A set sequence, with every clash solved before anyone is on site.
We read the drawings and specs, walk the site, and flag gaps before we price.
One price for every system, with clear inclusions and exclusions.
We model every system in 3D, run clash detection and issue coordinated drawings before install.
Every system installs to one schedule, run by one ALDA project lead.
Testing, commissioning, as-built drawings and warranties, handed over as one package.
One agreement for the whole systems scope, instead of four or five subcontracts.
Questions, RFIs and change orders go to one person who knows every system on the job.
No trade waits on another, and inspections line up.
Who we work with
We bid systems packages to contractors, work directly for business owners and homeowners, and give design teams the site information and coordination they need.
A single-source MEP and site package that shortens your sub list.
Pricing early in design, then delivery that holds to it.
Upgrades, fit-outs and replacements with minimal tenant disruption.
Commercial, industrial and institutional spaces, handled end to end.
Custom homes, additions and major renovations, with every system planned before the walls close.
Laser scans, as-builts and existing-conditions surveys to design from, plus systems pricing during design.
Hydrant flow tests, field verification and coordinated drawings that turn your design into an installable layout.
About ALDA
On most projects, the systems inside a building are bought as separate contracts. Mechanical, electrical, plumbing and fire protection each arrive with their own drawings, their own schedule and their own claim on the ceiling space. The gaps between those contracts are where most rework, change orders and delays come from.
ALDA Building Systems was started to close those gaps. We bring every system under one scope, coordinate it in 3D in our office, and manage the installation from start to finish. One team is responsible for how the systems fit together, from the first site scan to the final as-built drawing.
We're a coordination-first company. We investigate before we price, model before we build, and document what we install. Owners get a building they understand. Contractors get a scope they can rely on.
Scope builder
Pick what applies. We'll turn it into a scope sheet you can send with your pricing request, and suggest the investigations we'd normally run first. The selections below are an example; change anything.
Request pricing
Drawings help, but you don't need them to start. Send what you have, or we'll walk the site, document existing conditions and scope it from there.
