Occupied office renovation with staged remediation
With Pentillion Construction, I helped deliver a two-floor renovation for a high-value professional office client while the space remained in use. The work included removing and adding walls, replacing flooring, painting and finish upgrades, a new kitchenette, a new reception area, custom feature walls, blind replacement, HVAC reconfiguration, and new data wiring.
Renovating around an office that still had to function
The project became more complex once the flooring scope exposed asbestos-containing tile below the existing finish. Because the office remained active during construction, the remediation and renovation work could not be handled as one clean shutdown.
We brought in a professional remediation contractor and broke the work into multiple stages so the tenant could keep operating while offices were shuffled around the floor.
Coordinating design decisions, trades, and tenant moves
My role was a mix of coordination, design support, and hands-on field work. I coordinated between the tenant, landlord, architect, remediation contractor, and trades while also helping the tenant work through design details and practical decisions.
The work had to keep moving without losing sight of how the space was being used day to day. Walls, flooring, abatement, painting, lighting, blinds, HVAC, data, and millwork all had to be coordinated around people who still needed to use the space.
Making the reception finish hold up under real lighting
One of the more detailed parts of the project was the new reception area. The client had a specific look they wanted for the feature walls, and the wall-wash lighting made the finish quality especially important.
Any waves, seams, or surface defects would have been highlighted by the lighting, so the wall needed a high-quality, Level 5-style drywall finish along with careful custom carpentry and detailing. I helped work through how to make that design intent buildable, coordinate the finish requirements, and bring the reception area together with the level of finish the client expected.
A clean finish
The difficulty came from the setting, not one dramatic detail. Everything had to happen in a real occupied workplace, in stages, with people still needing the office to function.
The result was a completed two-floor renovation delivered through staged work in an occupied environment. It shows the practical side of tenant-improvement coordination: communicate clearly, respect the people using the space, make finish details buildable, and keep adapting when field conditions change the plan.
Bike room, showers, and service-space retrofit
With Pentillion Construction, I coordinated the retrofit of vacated tenant space into building amenity and service areas. The new program included bike storage, lockers, three shower stalls, an accessible washroom, an accessible combined shower and washroom, janitor storage with a mop sink, and a garbage room.
The design had to work for tenants, the landlord, building operations, accessibility expectations, and the service needs of the property. A space like this can look simple once it is complete, but the hidden coordination is what makes it usable.
The challenges with retrofitting an existing building
The retrofit involved fire separations between tenants and floors, subgrade plumbing, new washroom and shower layouts, secure access requirements, mechanical and electrical coordination, and revisions to engineered details so the work better suited the actual space.
The existing conditions mattered. Plumbing routes, wall layouts, access points, service spaces, and fire separations could not be solved independently. Each decision affected another part of the retrofit.
Coordinating consultants, trades, and adjacent work
My role was to coordinate between the architect, mechanical engineer, electrical engineer, Pentillion Construction, subtrades, and contractors working in adjacent tenant space at the same time.
I reviewed historical drawings, engineering plans, and architectural layouts to understand the existing conditions and help propose solutions that could satisfy the different stakeholders. The work required balancing design intent with field realities so the retrofit could move forward without creating conflicts for the surrounding construction.
Clean cut finish
The result was a more useful and serviceable set of building spaces. Accessibility, service use, plumbing, fire separations, secure access, consultant details, trades, and active building constraints all had to line up so an underused area could work as dependable building infrastructure.
Commercial office renovation and kitchenette fit-out
With Pentillion Construction, I helped coordinate a smaller commercial office renovation that included new interior walls, soundproofing review, kitchenette design and installation, glass doors and glazing, flooring, lighting, painting, and HVAC ducting.
The work was a compact tenant-improvement scope, but it still required the same kind of field coordination that makes these projects succeed. The layout, finishes, glazing, kitchenette, and building-system work all had to come together in a way that made the space feel complete and usable rather than like a collection of separate trade scopes.
One part of the work involved reviewing interior walls for soundproofing considerations. Another involved designing and installing the kitchenette so it fit the tenant’s needs and the available space. Flooring, lighting, paint, glazing, and HVAC ducting then had to be coordinated with the broader renovation sequence.
The project is a smaller example of practical tenant-improvement work: understanding what the tenant needs, coordinating the trades and finishes, and following through on the field details that turn an office renovation into a functional finished space.
Restaurant shell conversion in an existing building
With Pentillion Construction, I represented the building owner through the conversion of a former single-tenant ground-floor commercial space into a demised shell for an incoming restaurant tenant. What began as a landlord-side turnover scope became a broader technical coordination project involving lease obligations, existing building systems, consultant drawings, trade scopes, tenant requirements, landlord requirements, field conditions, older infrastructure, code review, and schedule pressure.
My role was project engineering support and owner-side coordination. I was not the engineer of record, but I investigated existing conditions, developed practical options, coordinated consultant review, and translated technical issues between trades, suppliers, consultants, ownership, and property management. Much of the work was about finding a buildable path through existing-building constraints without overstepping the professional roles of the design consultants.
Electrical capacity without replacing obsolete switchgear
One of the major constraints was electrical capacity. The incoming tenant required a significant electrical service, but the existing switchgear was older and difficult to modify. The expected path had been to remove existing chiller equipment to free up a 600 amp switch for the new tenant service.
Through field review, I identified that some base-building air-handling equipment was connected to oversized switches from an earlier arrangement. I proposed relocating one of the air handlers onto an existing oversized switch already serving chiller equipment, which freed a 600 amp switch for the tenant service.
After review by the electrical engineer, that approach was accepted and implemented. It avoided removing chiller equipment, avoided modification of obsolete switchgear, reduced feeder complexity, preserved future flexibility, and helped keep the turnover moving.
Fault-current and series-rating coordination
The electrical scope also required coordination around available fault current and series-rating requirements. This was not the kind of issue that could be left vague until ordering. If the panel requirements were misunderstood, the result could have been a purchasing mistake or a schedule delay.
I researched the requirements and coordinated between the electrical engineer, contractor, supplier, and manufacturer so the panel selection could be checked against the actual project conditions. My role was to help keep the technical question moving between the right people so the final decision was properly reviewed and documented.
Separating HVAC systems
The ground-floor space had previously functioned as one larger single-tenant area. The turnover required the incoming tenant to be separated from the remaining area so both spaces could operate independently.
I reviewed the proposed HVAC approach and flagged concerns with continuing to rely on shared base-building air-handling equipment. Working with the mechanical team, I helped coordinate a revised approach that redirected supply and return ducting so the incoming tenant could be isolated from the shared air system.
This was a practical example of looking beyond the drawing and asking how the system would actually operate after demising. The issue was not only whether ductwork could be installed, but whether the resulting system would give the landlord and tenants the separation they needed.
Underground plumbing through an existing slab
The restaurant shell also required new underground plumbing through the existing slab. I reviewed historical drawings and consultant drawings to understand likely service locations, then coordinated scanning, slab cutting, excavation, tie-ins, backfill, and concrete reinstatement.
The work had to move carefully because existing drawings can only tell part of the story in an older building. The field work needed enough planning to reduce surprises, but also enough flexibility to respond once the slab was opened and the real conditions were visible.
Hazardous-material sequencing
As the work progressed, hazardous-material concerns had to be identified, isolated, and sequenced without derailing adjacent work. I arranged testing, marked affected areas, brought in remediation specialists, and coordinated the work so the issue could be resolved safely and in the right sequence.
I was not performing the abatement, but I helped keep the issue from becoming an unmanaged project risk. The practical value was recognizing the constraint, getting the right specialists involved, and keeping the surrounding work coordinated.
A practical code path for the equipment platform
One of the more complicated issues involved an internal platform that had been designed and built based on an earlier building assumption. Later review confirmed that non-combustible construction was required. By that point, mechanical equipment had already been installed above the platform, so replacing the supporting structure with steel would have created major cost and schedule impact.
I worked with the architect and code consultant to investigate a practical compliance path. That included researching rated assembly options, identifying a listed rated ceiling and grid assembly for review, checking what had already been installed, determining required changes, and coordinating the accepted solution.
The final path used protected assemblies, Type X drywall, rated ceiling components, firestopping, and revised sprinkler protection. The value was not in bypassing the requirement; it was in helping the team find a compliant way forward that fit the real project condition.
Meter troubleshooting and handoff
After installation, the tenant power meter was not reading correctly. I contacted technical support, sourced a USB-RS485 adapter, connected directly to the meter, and found that the sensing breaker arrangement had changed during tenant-side work.
I updated the programming and confirmed corrected readings. It was a small part of the overall project, but it was a good example of the same pattern at a smaller scale: understand how the system is actually wired and operating, then make the practical correction needed for handoff.
The power of collaboration
The project brought together electrical capacity, obsolete infrastructure, HVAC separation, underground plumbing, hazardous materials, code review, consultant coordination, tenant requirements, landlord obligations, and schedule pressure.
My contribution was helping those issues stay connected instead of letting each one become a separate crisis. That meant looking ahead, asking sideways questions, involving the right specialists, and turning uncertain field conditions into reviewed, buildable paths.
The owner-side coordination value was making sure the right information reached the right people early enough that the project could keep moving.
Veterinary clinic tenant improvement
With Pentillion Construction, I helped deliver the James Bay Veterinary Clinic tenant improvement: a conversion of a former bank into a veterinary clinic of roughly 3,800 square feet, or 353 square metres. The finished clinic included reception, six exam rooms, surgery, dental, storage and equipment space, washrooms, an office, and support areas.
Turning a former bank into a clinical space
The project was more than a standard interior refresh. A former bank and a veterinary clinic have very different operating needs.
The new space had to support public/client-facing reception, clinical workflow, treatment and procedure areas, equipment needs, staff support space, storage, durable finishes, and the building-system coordination required to make those spaces work.
Working through the existing shell
The existing bank condition added complexity, including the constraints created by the former vault and the need to adapt the commercial shell to a specialized tenant use.
That meant the work had to be coordinated carefully across layout, demolition, framing, plumbing, HVAC, electrical, finishes, millwork, equipment coordination, and permit requirements.
Keeping the construction information moving
My role was hands-on project coordination and field support. I helped define scopes, coordinate trades and labour, update drawings, create Gantt charts, support permit coordination, and work through day-to-day field issues as the project moved from drawings into construction.
I was not the architect or engineer of record, but I helped keep the project information moving between the people who needed it. That mattered because specialized tenant improvements depend on timely decisions, clear scopes, and practical coordination between drawings, permit requirements, site conditions, and field labour.
Managing schedule pressure and supply-chain constraints
The schedule also had to be managed through post-COVID supply-chain constraints. Materials, equipment, and trade availability could not always be treated as predictable, so the project needed active tracking, sequencing, and communication to keep the work moving despite delays and changing availability.
A key part of the work was translating the tenant improvement scope into a practical construction sequence. The clinical layout had to become a real space with the right trades in the right order and the right information available when decisions were needed.
Not just a pet project
The result was a completed tenant improvement that turned a former bank into a functioning veterinary clinic. It shows a full commercial conversion with specialized operating requirements, active field coordination, drawing updates, scheduling, permits, and trade sequencing. The drawing set, field conditions, tenant needs, trades, schedule, and supply-chain constraints all had to be kept connected until the space could actually operate as a clinic.
