Commercial construction and mechanical engineering, done properly
Kitchen extraction is the most routinely ignored asset in commercial buildings — until a fire investigator, or worse, a loss adjuster, pulls it apart. We examine one restaurant group's costly encounter with TR/19 non-compliance and set out a regime that landlords and tenants can agree on before the insurers ever ask.
Most commercial buildings are only ever inspected when everyone is awake — precisely when they are on their best behaviour. A nocturnal walk-through reveals the running costs that daylight hides, from heating empty floors to lighting nobody is using. Here is what our engineers look for when the building thinks nobody is watching.
A condensate drain failure in an unoccupied office block ran for nearly fourteen hours before anyone knew. We reconstruct the timeline from BMS logs and the email trail that followed — and find that the £250,000 loss was visible in the data weeks before the water arrived.
A filter left in too long rarely makes headlines — until the air handling unit it starved finally gives up. We trace the four-year timeline of one degraded AHU to show exactly where a small job became a capital problem, and what a modest monthly routine would have preserved.
The plant room is where a cautious tenant's due diligence actually begins, long before the solicitors get involved. Here's how to present your mechanical services honestly — and why a well-prepared viewing can shave weeks off your void period.
A tenant-installed fan coil unit looks like the tenant's asset — until the dilapidations surveyor arrives and it becomes the landlord's liability. We trace one dispute through the lease, the service charge and the plant room to show why mechanical asset ownership must be defined in writing before installation, not litigated afterwards.
A forgotten dead-leg above a mezzanine office became a compliance black hole spanning landlord, tenant and managing agent. We trace how accountability dissolved across three layers of management — and what a genuinely thorough legionella risk assessment looks like when it's done properly.
Corporate occupiers now send sustainability teams — not just surveyors — to assess buildings before signing a lease. Their scrutiny of plant performance, metering and maintenance records is reshaping the letting process. Landlords who embrace transparency are discovering it can be a selling point rather than an exposure.
We followed a single ageing chiller on a Thames Valley business park through a full year of bills, call-outs and tenant grumbles. The arithmetic is uncomfortable reading for anyone who signs off a service charge budget.
July and August offer commercial building operators a rare commodity: empty floors, closed risers and quiet plant rooms. Used well, this low-occupancy window can absorb works that would otherwise cost a fortune in disruption — or spiral into autumn emergencies.
Two identical office buildings, two very different maintenance bills. We compare five years of callbacks, energy spend and downtime to show why the handover period is the most neglected phase of any commercial build — and what a disciplined first 100 days looks like.
Snagging lists are supposed to shrink. On most commercial mechanical contracts, they do the opposite — swelling from a tidy spreadsheet into a semi-permanent feature of the building. We follow one real list from practical completion to its third Christmas and ask who, exactly, benefits from items staying open.
Drip trays, humming AHUs and doors that suddenly need a shoulder — the earliest warnings of mechanical failure rarely appear on a BMS dashboard. They appear to the people who walk the building at 4am. It is time facilities managers treated their cleaning and security teams as a genuine diagnostic asset.
A thin, generic operation and maintenance manual handed over at practical completion is one of the most expensive documents in commercial property. We look at what poor handover documentation really costs in engineer hours, voided warranties and guesswork maintenance — and why contractors should be held to a proper pack before anyone signs off.
IoT dashboards promise predictive maintenance and lower running costs, but too many UK landlords end up paying for expensive wallpaper. We sort the genuine wins from the gimmicks, with input from the facilities managers who live with the consequences.
A 4,200 square metre commercial estate in the Midlands replaced failing boilers and outdated controls with a heat pump-led system — and the tenant's capital budget barely noticed. We walk through the funding stack, the paperwork and the lessons for landlords who assume their plant room doesn't qualify.
Building management systems run the heating, ventilation and energy performance of most UK commercial stock — and too many of them are still protected by factory settings. We set out the five vulnerabilities we encounter most often on site, and a hardening checklist facilities managers can act on this quarter.
When heating, ventilation and water systems serve several landlords and a dozen tenants, responsibility tends to dissolve into nobody's job. We look at what happens to a building when no one signs a maintenance agreement — and how a tri-party contract puts it right.
Every January our snagging teams clear the same handful of defects, and almost none of them were caused on site. From undersized plant to controls that never speak to each other, here are the five fit-out fails we see most often — and the specification language that would have prevented them.
Commercial purchasers routinely commission structural surveys and pore over lease schedules, yet the plant room — often the building's single largest future liability — goes uninspected. We walk through what a mechanical due diligence exercise should cover before exchange of contracts.
