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.
Access control and building security upgrade
With Pentillion Construction, I helped coordinate an access-control and security-system upgrade for a commercial building. The work included access-controlled doors, elevator access, cameras, wiring routes, and the operational requirements needed by both the landlord and tenants.
The project was not just a matter of selecting hardware. The scope had to balance security, usability, cost, code requirements, tenant disruption, and long-term building operations. I helped define which access points needed to be controlled, what the system needed to do, and how the work could be coordinated across the security contractor, electricians, elevator company, automated door contractor, tenants, and landlord.
One of the key constraints was elevator access. The building needed more controlled access to certain areas, but a full elevator-control upgrade would have added cost and complexity beyond the practical scope of the project. I worked through the requirements with the contractor and helped shape a solution that controlled access where it was needed without overbuilding the system.
The project also required code interpretation around the building’s crossover floor. Because the crossover floor formed part of the life-safety and exiting strategy, the access-control approach had to preserve the required function of that floor rather than treating every door as a simple security device. That added an important check on the design: the system still had to support safe movement and code-required access while improving security.
I also coordinated wiring routes with the contractor and helped manage the system after installation. That included programming useful operational automations, such as event-based actions that supported day-to-day security and reduced manual steps for building management.
The result was a more practical access-control system that served landlord and tenant needs without turning the project into a larger elevator-modernization or building-wide security rebuild. It shows the value of defining the real operating requirements before selecting a technical solution, then coordinating the trades and code constraints needed to make the system work.
HVAC controls retrofit and system troubleshooting
With Pentillion Construction, I helped audit, explain, and coordinate upgrades to an older HVAC control system. The building had existing controls and hardware that could not simply be replaced all at once, so the project needed a clear understanding of what was already there before the new work could be planned.
Understanding the old system before replacing parts of it
My role was to bridge the gap between the existing controls, the HVAC contractor, the controls contractor, and the practical needs of the building. I reviewed and documented how the system operated, helped explain the existing logic, and supported the retrofit so new equipment could be integrated without losing compatibility with parts of the older setup.
The upgrade included four new heat pumps. Because I had built much of the internal understanding of the existing controls, I became a practical reference point during the work. The value knowing what equipment was present and helping the contractors understand how the old controls, operating logic, and building requirements fit together.
Troubleshooting the shaking air handlers
That same system knowledge carried into troubleshooting. The building had two large air handlers that were shaking under certain operating conditions, and the cause had not been identified.
One proposed path was to bring in an engineering audit to measure resonant frequencies using specialized equipment. That may have been needed eventually, but before jumping to that step, I worked through a more direct inspection of the system.
Looking for the real field condition
I checked likely mechanical causes, including whether the air-handler shafts appeared to be off balance, the dampening system, and used a 360 camera and thermal imaging camera to inspect areas that were difficult to access directly.
That investigation pointed toward a loose sheet-metal wall dividing the large duct that supplied hot and cold air to the building. Under certain airflow and pressure conditions, the loose partition deflected until it relieved the pressure differential, then snapped back, allowing the pressure to rebuild and repeat the cycle. This created a low-frequency pulsation that transmitted vibration into the air-handler area and surrounding building structure.
A logical conclusion
I documented the old controls, identified what still had to work, coordinated the contractors around the real operating logic, and investigated the field condition before assuming the next step had to be expensive or abstract.
The result was a building system that became easier to explain, upgrade, maintain, and hand off.
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.
Fire panel relocation and life-safety retrofit
With Pentillion Construction, I helped coordinate a fire alarm system retrofit in an occupied commercial building. The existing fire panel was outdated and located inside a secure tenant area, which created access and operational constraints for building management, contractors, and emergency-related service work.
The project involved more than simply replacing equipment. The panel needed to be upgraded and relocated to a more appropriate building service area, while related alarm devices such as bells and pull stations also needed to be reviewed and upgraded as part of the broader retrofit.
I engaged multiple contractors to understand the available paths forward and help shape a practical scope. The work required coordination between the fire alarm contractor, security contractor, electrician, tenants, and building operations. Because the existing panel location was inside a secure space, access had to be planned carefully and coordinated with the affected tenant and other building users.
The crossover-floor requirements added another important layer. Because crossover floors form part of the building’s life-safety strategy, the access and fire alarm work had to be considered in that context rather than treated as a simple equipment swap. The retrofit needed to improve serviceability and bring the equipment into a better location while preserving the required life-safety function of the building.
The result was a more serviceable fire alarm system with the panel relocated out of the secure tenant space and related devices upgraded as part of the work. The project shows the coordination behind a relatively contained building-system upgrade: understanding the operational problem, checking the code-related constraints, aligning the right contractors, and completing the work without exposing tenants or building users to unnecessary disruption.
Custom glass awning redesign and installation
With Pentillion Construction, I delivered a custom glass awning replacement where the design intent was clean and visually simple, but the existing building made the installation much more complicated than the drawings suggested.
The project replaced existing vinyl awnings with a suspended glass canopy system supported by steel outriggers and diagonal tie rods. The challenge was making that system work on the real building, with the right tolerance, alignment, drainage, serviceability, and installation sequence.
The hidden structure did not match the clean drawing
The upper tie-rod anchors were intended to connect back to the structural concrete spandrel beam, but that beam was hidden behind exposed-aggregate precast architectural panels with an inconsistent air gap behind them.
That changed the problem. The anchors could not simply be fastened as drawn, and the inconsistent gap made it difficult to scan the structure and confidently locate reinforcing steel before drilling. The installation needed enough field tolerance to avoid reinforcement while still leaving the finished awning visually aligned from the street.
Making the anchorage adjustable without looking like a fix
I helped investigate the existing condition and separate what was architectural cladding from what was part of the structural load path. That understanding shaped the redesign of the upper anchorage.
The detail needed to bridge through the architectural panel, connect back to the structure, and still allow the installer to shift final anchor locations where needed. The exposed cover plates then had to conceal that adjustment zone without looking like an afterthought.
The tie rods also had to stay visually aligned even when the hidden anchors had to move. The connection evolved toward a more adjustable arrangement using clevises and paired plates, with practical details such as wrench flats and opposite-handed threading so the rods could be adjusted in place.
Letting the glass layout respond to the building
The lower outriggers created another coordination problem. Their locations needed to avoid likely reinforcement while still supporting the glass layout. With the architect’s approval, the glass panel widths were allowed to vary within a controlled range so the steel supports could respond to the real structure instead of forcing a layout that was difficult to install.
The glass support detail also had to be reconsidered. A more fixed pressure-plate approach would have made installation and future service more difficult, especially if individual panels ever needed to be removed. Working with the installer, we moved toward a more serviceable approach that better suited how the glass would be handled, installed, and maintained.
Designing the corner so it could actually be fabricated
The corner conditions added another layer of practical design work. The corner framing had to coordinate glass sizes, steel fabrication, galvanizing, fit-up, and installation sequence.
I raised concerns about field welding galvanized steel and helped move the approach toward details that could be fabricated and installed more predictably. When galvanizing distortion became a concern, I helped look for a simpler framing approach that better matched the typical outriggers and reduced the risk of a distorted corner assembly.
Turning layout into a repeatable field process
A major part of my contribution was turning the layout problem into something the installer could repeat in the field. Because the outrigger and standoff locations varied along the building, there was no simple continuous datum for every cored opening.
I designed and 3D printed a positioning jig that sat on the installed outrigger and held a laser-cut template board for the core-hole locations. The template allowed the layout to shift when needed to avoid reinforcement while maintaining the relationship between the outrigger, standoff, and tie rod.
Dealing with drainage after the slope changed
The project also had to respond to drainage requirements. A late requirement changed the awning slope so water drained back toward the building rather than away from it.
That meant reviewing tie-rod geometry, glass slope, flashing, and gutter details so the finished system could manage water without creating maintenance or building-envelope problems. I helped develop a custom gutter approach that could be installed with the completed steel and glass while remaining serviceable and cleanable.
Keeping the work moving on site
Alongside the design and coordination work, I supported day-to-day site execution. That included coordinating with the architect, structural engineer, fabricators, glass contractor, sheet metal contractor, crane company, tenants, and site team; helping maintain scaffold access; developing site-specific safety procedures; removing existing awnings and flashing; coordinating electrical and signboard-related work; reviewing layout; resolving field discrepancies; and checking installation details as the work progressed.
A clear vision
The finished awning looks clean because we solved a lot of messy problems before they became visible. Hidden structure, reinforcement risk, anchor tolerance, glass layout, galvanizing, drainage, installation access, and future service all had to be handled together.
This project shows how I work between drawings and the field. I ask how an idea will be located, fabricated, adjusted, installed, drained, maintained, and handed off.
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.
Enterphone data recovery and audio repair
A building’s Mircom TX3 enterphone failed, and the first risk was not just getting the hardware working again. The resident directory and system configuration also needed to be protected. Replacing the controller board without recovering the data could have turned a hardware failure into a larger setup and handoff problem.
I traced the failure through the power supply, transformer, door strike circuit, phone line, and controller board. The likely failure was in the board’s low-voltage power section, where a small surface-mount capacitor had burned.
Instead of immediately replacing the board and losing the configuration, I powered the damaged board with a current-limited DC bench supply. That let me bring the board up carefully, confirm that the internal 5V and 3.3V logic rails were stable enough to communicate, connect to the TX3 software, and recover the resident names and configuration before replacing the board.
After the new board was installed, I updated the configuration and verified the building functions tied to the panel. That included the postal lock input, door strike operation, grounding, phone-line settings, and relay behaviour. The goal was to leave the system in a known working state, not just swap the failed component.
There was also a call-audio issue where the caller’s voice became quiet after the call connected. I tested microphone gain, speaker level, DTMF sensitivity, and echo-reduction profiles. The issue appeared to be aggravated by sound reflecting inside the panel and around the speaker/microphone assembly, which could cause the echo reduction to clamp down unnecessarily.
I repaired and sealed the broken speaker enclosure and started working on a simple acoustic treatment around the microphone to reduce reflected traffic noise. It was a small repair, but it reflected the same troubleshooting approach as the board recovery: trace the system, protect the important data, verify the handoff, and keep looking when the first fix does not fully solve the user experience.
Industrial infrastructure project management at Harmac
My role at Harmac Pacific started early in my career and expanded my project management experience in an industrial operating environment. The work was different from commercial renovation work: the scale was larger, the consequences of downtime were higher, the stakeholders were broader, and the field conditions were often less forgiving.
The main thread was practical industrial coordination. I worked with operations, maintenance, trades, contractors, utilities, residents, property owners, environmental stakeholders, and regulatory agencies while helping move mechanical and infrastructure projects from planning into execution.
Pipeline replacement through difficult terrain
One of the major projects was part of Harmac’s water supply pipeline replacement. The work involved replacing roughly 1,200 metres of 52-inch creosote-soaked wooden stave pipe with 48-inch HDPE pipe. My role focused on managing and coordinating difficult stages of the work where the pipe route, access, environment, and existing structures made the work more complicated than a straightforward pipe replacement.
A key challenge was that sections of the old wooden pipe were on trestles over environmentally sensitive areas. Access was limited, the old material required care, and the project had to protect both the surrounding environment and the remaining support structures while keeping the replacement work moving.
Helicopter removal and trestle protection
For one difficult stage, the old pipe sections had to be removed from a trestle where conventional access was limited. I helped coordinate the removal strategy, including the use of a helicopter lift to remove old pipe sections from the site.
The new HDPE pipe also had to be pulled through a route where the trestle needed protection from excessive loading. Rather than defaulting to a more complex equipment approach, I helped develop a method using a sacrificial cable and a secondary restraint cable. The sacrificial cable provided a controlled weak link, while the restraint cable helped protect the trestle if the pulling force became too high.
That approach allowed the work to proceed without installing a torque-limited winch onto an excavator, reducing complexity while still giving the team a practical safeguard for the structure.
Simplifying another stage with culverts
On another stage of the pipeline work, I reviewed the constraints around existing trestles and HDPE pipe flexibility. Based on that review, I suggested removing unnecessary trestles and replacing the approach with culverts where appropriate.
That kind of decision was less dramatic than a helicopter lift, but it reflected the same pattern: understand the real constraint, check whether the assumed construction method is actually necessary, and look for a simpler path that still satisfies the project needs.
Chlorine dioxide mixer replacement
I also supported replacement of an aging chlorine dioxide mixer in a harsh pulp-mill chemical environment. The work involved materials and details that had to suit the service conditions, including titanium valves, 317L stainless steel, fiberglass components, and Derakane epoxy vinyl ester resin.
That project required coordination across safety, maintenance, operations, materials, procurement, contractors, and installation planning. In that environment, the design and material choices mattered because the equipment had to survive chemical exposure and fit into an operating industrial system.
Drawings, procurement, and contractor coordination
My work also included preparing RFQs and RFPs, using weighted criteria for contractor selection, and producing technical information needed by fabricators and contractors. I designed machinery bases and lifting equipment in SolidWorks and produced manufacturing, assembly, layout, foundation, and lifting drawings.
Those drawings were not just documentation. They were part of the handoff between engineering intent, fabrication, installation, safety planning, and field execution. In an industrial environment, unclear drawings or incomplete scope can quickly turn into shutdown risk, contractor confusion, or unsafe work conditions.
An early-career lift
This work came early in my career, but the systems and consequences were large. It put me in the middle of operating industrial infrastructure, environmental constraints, old structures, contractor decisions, hazardous-service equipment, and shutdown pressure.
The pattern still shows up in my later work: understand the system, verify the field condition, involve the right people, and find the practical path that lets the work move forward safely.
