VariousLowRoutine maintenanceexcluded
Six of twelve items are logged by the surveyor as routine maintenance with cost excluded. In a vacant building with no occupier and a property manager visiting periodically, "routine maintenance" is the category most likely to not happen — and gutters and vegetation are precisely where that ends in water inside the building.

EA position

Condition
Sound where visible; largely concealed by vegetation
Title
Demise extends beyond the west boundary fence to the riverbank; boundary required detailed investigation
Vegetation was cleared in 2021 to give the EA access. Ongoing clearance is needed to maintain access and allow future inspection.

Spent on
Predominantly landscaping and litter picking
Condition
Operating sufficiently, fair. Cracking to kerbs to address
Access rights
Various rights associated with neighbouring properties
The TDD flags that this obligation and the recovery of costs from Units A and C will need to be actively managed. Recovery that is not chased is leakage.

Flood risk position

Mapping disputed
✓
Rivers and sea — LOW risk
Site designated low risk on the Gov.UK long-term maps. The area beyond the west embankment is high risk.
◮
Surface water — HIGH risk on the footprint
Majority of the site including the building footprint mapped high; medium and low areas in the north and west yards.
◈
Consultant's view: mapping artefact
Nova Ambiente: LiDAR processing removes the building and interpolates ground level, creating artificial depressions. Mapping also does not account for surface water drainage infrastructure.
Live river level for this site is available free. See Real-Time Feeds.

Why the roof first

£
Two guarantees run to 2036
Cut-edge corrosion treatment and the Girosil RC-G gutter liner, both from 2021, both 15-year. A claim needs dated evidence of the defect.
◮
Gutters already failing outside the guarantee
Landlord has made ad-hoc repairs where lining joints were splitting. Standing water and vegetation observed.
◈
Internal siphonic drainage
160 mm uPVC downpipes run inside the building. A gutter failure discharges internally, onto a floor coating re-laid in 2026.
◱
Rooflights at ~10% of floor area
Triple-skin GRP from 2003, heavily soiled. Also a fall-through consideration for any roof access.
◔
Single roof hatch, Mansafe system
Recertified 2021. Ground-based methods see none of the above — the roof is invisible without a flight.

Baseline first, trend later. A single scan of an empty slab is a schedule of condition and nothing more — it tells you the state, not the rate. Deterioration only becomes measurable from the second scan, which means the value of this screen is realised in year two, once the building is occupied and the floor starts taking traffic.

Electricity — half-hourly consumption
No hardware required if the MPAN is half-hourly settled. The building is vacant, so the landlord is most likely the registered customer — which removes the usual tenant-consent obstacle.
Supplier / HHDC
Half-hourly
One phone call
Levels are measured every 15 minutes but transferred to the EA typically once or twice a day, increasing during heightened flood risk. So the reading can be hours old in calm weather and near-real-time in a storm. The dashboard must show the data timestamp and must not claim continuous monitoring.

Read the existing contacts rather than instrumenting the pumps. LPCB-approved sprinkler control panels already monitor pump run status, pressure and supply, and already provide volt-free outputs intended for a BMS. The interface must be passive and isolated, and signed off by the sprinkler maintenance contractor.

✕
CO₂ and air quality
Nobody is breathing. Zero information content.
✕
Occupancy and people counting
Same — and camera-based counters bring UK GDPR obligations for no benefit.
✕
Dock leveller cycle counting
No cycles. Worth fitting when the building is let and the 2003 Crawford units start working again.
✕
VRF performance monitoring
The system should be off or on frost-stat. Monitoring an idle system tells you nothing.
✕
Sub-metering by area
Nobody to apportion to, and the demise boundaries are not yet known.

Cheap tiltmeters on the river wall
Ask the structural engineer first. This is not an IoT decision.
Demonstration prototype. Asset facts, condition findings, warranties, liabilities and the repairs budget are taken from the Savills Technical Due Diligence Report for this property (inspection 30 June 2026, Final 30 July 2026) and its appendices. Capture screens are intentionally empty and carry no simulated survey data. Cost estimates for capture and sensing are drawn from research current to September 2026; published prices and estimates are distinguished in the underlying costed plan, and no figure here is a quotation. Element lifespans are not shown because the source report does not state them. Before any external use, mask the owning entity, remove the named surveyors, and consider withholding the Repairs Budget screen.
