Aerial Imagery on a Live Construction Site: Showing the Job to People Who Are Not There

September 11, 2026|Categories: All, Featured, Inspection and Survey|

A construction project always has more people with a stake in it than it can have standing on the site. An aerial record shows the whole plot in one frame, with the boundary, the compound, the access and the works in their correct relationship, so people who cannot get there still understand it. This piece covers that use, what flying over a live workplace actually involves, and where a visual record stops and measurement begins.

Why an Aerial Thermal Survey Is Booked Against a Window, Not a Date

An aerial thermal survey records a temperature difference, and that difference has to exist when the image is taken. Conditions are therefore not a preference but a precondition, and different assets want opposite weather: a photovoltaic array needs bright, stable sun, a building envelope needs a cold night after dark. This piece sets out what the standards ask for, why each figure exists, and what booking against a window rather than a date means in practice.

What Turns Inspection Photographs Into a Record You Can Use Later

September 11, 2026|Categories: All, Featured, Inspection and Survey|Tags: Annotated Images, Building Inspection, Deliverables, Photographic Record, Roof Inspection, Visual Inspection|

An inspection happens on one morning, but its photographs are usually needed months later by somebody who was not there. What makes them usable then is not the drama of the aerial view. It is whether each observation is marked where it sits, whether close detail is paired with a frame that places it, whether coverage is systematic enough that absence means something, and whether the set can be navigated at all.

Flying a Drone Near an Airport: What a Flight Restriction Zone Means for Your Site

September 11, 2026|Categories: All|Tags: Aerial Photography, Airspace, CAA, Commercial Property, Drone Operations, Flight Planning, Flight Restriction Zone, Site Access|

Plenty of commercial property sits close to an airport, and a Flight Restriction Zone reaches well beyond the perimeter fence. A site two miles from a runway, with no view of it, can still sit squarely inside the zone. This post explains what those zones cover, the three separate permissions that people tend to treat as one, why the airspace approval is assessed flight by flight rather than granted once, and what to tell your operator before the date is agreed.

Reading a Roof Thermogram: Why the Pattern Proves More Than the Temperature

September 11, 2026|Categories: All, Featured, Thermography|Tags: Building Envelope, Emissivity, EN 13187, Qualitative Thermography, Reflected Apparent Temperature, Roof Thermography, Survey Conditions, Thermal Imaging|

Ask what temperature difference proves a roof is wet and you will be given a number. It is the wrong answer to the wrong question. A thermal camera measures surface temperature, arrived at through emissivity, reflection and viewing angle, and what identifies trapped moisture is behaviour over time rather than magnitude. This post covers what the camera is really reading, why saturated material lags behind dry material as a roof cools, and the conditions that decide the result before anyone flies.

Storm Damage to a Roof: What to Record, and How Soon

September 11, 2026|Categories: All, Featured, Inspection and Survey|Tags: Aerial Photography, Building Inspection, Roof Inspection, Short Notice Work, Storm Damage, Visual Inspection, Weather Damage|

A storm goes through and the roof is suddenly the one part of the building nobody can safely climb. This is a practical look at what to do in the first few days: how soon a roof can realistically be photographed from the air once the weather allows, what makes those images worth having later rather than merely reassuring now, and where a visual inspection stops. Written for building owners, landlords and managing agents across the South East.

Can Every Solar Array Be String Tested? What the Design Decides

September 9, 2026|Categories: All, Featured, Solar|Tags: Asset Management, Commissioning, Electrical Verification, IEC 62446-1, Power Optimisers, Solar PV, String Testing, Survey Planning|

Enquiries for electrical string testing usually lead with the array's size, and capacity is rarely the number that decides the job. How the system was wired, what sits behind each module, and who is available to open and isolate the boxes decide whether a string test is straightforward, expensive or not conventionally possible at all. This piece sets out the three things worth establishing before anyone quotes a price or commits to a date.

Air Leakage and Air Pressure: What Makes a Leak Visible to a Thermal Survey

September 9, 2026|Categories: All, Featured, Thermography|Tags: Air Leakage, Air Pressure, Building Performance, Building Thermography, Infrared Survey, Thermal Imaging Air Leaks|

Air leakage is only visible to a thermal camera when something is pushing air through the building fabric. Stack effect, wind and mechanical ventilation each create that pressure difference, each acts differently on different elevations, and each can disappear during a survey. This piece explains what drives air through a building envelope, why leakage appears as a spreading plume rather than a hard edged patch, and where a thermal survey stops and a pressurisation test begins.

You Fly It, We Certify It: What Remote Thermographic Reporting Can and Cannot Establish

A drone operator in Scotland flew three multi-storey residential blocks in the spring of 2025. They had the aircraft, the payload and the access, but nobody able to sign the result as a certified thermographic inspection. We wrote the capture protocol for their team before the flight and certified the reporting afterwards. This piece covers why the protocol comes first, what the analysis established, and what remote reporting genuinely cannot settle.

What a Heat Loss Survey Needs From You, and What You Get Back

September 9, 2026|Categories: Featured, Inspection and Survey, Thermography|Tags: Building Envelope, Building Thermography, EN 13187, Heat Loss Survey, Qualitative Thermography, Survey Planning, Survey Preparation, Thermal Imaging Report|

A building heat loss survey looks like a single cold night's flying, but most of what decides its value is settled beforehand. This piece sets out the information a thermographer needs from the building owner and why each answer changes how a thermal pattern is read, what has to be arranged before an after-dark survey of an occupied building, and what the finished report contains, including the difference between a certified inspection report and a professional opinion.
