A buyer's diligence framework for construction AI vendorsA vendor-neutral list a document controller can take into a demonstration: who owns the training data, whether answers pin to the issued set, whether you can export the record, and who is liable when the model is wrong.25 Aug 2026 · Learning · AI · 11 min read
Four cream diligence cards in a row on a pale-grey contractor HQ boardroom table: a brass padlock on title-block sheets, a steel pin through a clipped revision bundle, an open brown archive box with a USB stick, and a red desk stamp with ink pad; a document controller's hands align the pin card, brick facades through an office window.
ISO 19650:2026: what the revision changes and who should careA revision of ISO 19650 typically tightens three seams the 2018 and 2020 parts already named — information need, CDE states, the AIM — rather than inventing a new religion. Read a draft against those published texts, not against a cover year.16 Jun 2026 · Learning · CDE · 14 min read
A walnut standards-library shelf: three unmarked cloth-bound volumes in grey, navy and olive occupying published bays, an empty reserved slot with a blank cream card in a brass holder, and a watcher's two-column notebook open on the reading ledge.
Connecting a CDE to a CMMS without a two-year integration projectThree practical joins already sit between a common data environment and a computerised maintenance system: a shared asset identifier, an export of the asset information model, and a scheduled sync. Each has a named failure mode. None of them is a two-year programme.2 Jun 2026 · Learning · Operations · 13 min read
Overhead documentary still of a grey steel facilities bench: a hole-punched CDE asset-information extract on the left, a yellow-pink CMMS work-order card on the right, one stamped stainless asset-ID tag overlapping both sheets, and a single unused black patch cable beside them; galvanised plant casing and a hook rack of blank tags in the background.
A handover acceptance checklist for ownersDo not accept keys against a ZIP. Before you sign, test the asset register, O and M, warranties, as-builts, the issued set, and a named AIM owner — on the same day, with identities you can still refuse.21 Apr 2026 · Learning · Handover · 15 min read
An owner in a charcoal blazer stands at a finished lobby threshold holding a clipboard with a six-row handwritten score sheet and a tagged set of brass keys, an unfinished open crate of loose folders behind them.
COBie explained without the spreadsheet traumaCOBie is a handover schema for asset information. The trauma is what happens when that schema is applied once, at the end, as an Excel dump nobody validated and no operator can query.3 Mar 2026 · Learning · Handover · 12 min read
A small scuffed aluminium plant asset-tag on a split ring, sharp in the foreground against a breeze-block wall; behind it a three-metre printed spreadsheet banner hangs from clip-hooks, a blurred wall of empty cells.
The handover readiness review, run at sixty per cent completeA readiness review at sixty per cent complete is a mid-project gate: asset tags, ITPs, O and M drafts and the issued set, while the people who can still close the holes are on the job. The same review at practical completion is a surprise.20 Jan 2026 · Learning · Quality · 11 min read
On a daylight construction hoist landing at mid-height of an unfinished concrete frame, two site people review a printed four-row readiness score sheet on the chequer-plate deck beside a newly delivered air-handling unit, open slab edges and services going in behind them.
A defects workflow your subcontractors will actually useDesign the item for the trade who closes it: a photograph they can take, a location they can walk to, an issued-set pin they can trust, and a close-out they can finish in gloves. A list built for the office logger is labour the main contractor performs for free.13 Jan 2026 · Learning · Quality · 16 min read
A trade closer photographs a door-reveal defect at arm's length, an issued-sheet extract taped to the leaf beside the jamb, late-afternoon light in an unfinished plaster corridor.
Inspection and test plans tied to asset tags from day oneHandover does not assemble in the last fortnight. It assembles when every inspection and test plan is written against an asset tag from the first hold point, not against a spreadsheet named after a trade.16 Dec 2025 · Learning · Quality · 9 min read
A factory worker in grey overalls and leather gloves rivets a small blank metal plate onto a galvanised air-handling unit while a paper inspection sheet hangs from a clipboard clip on the same cabinet, under cool fluorescent shop-floor lighting.
Building a delay record that survives adjudicationContemporaneous is not a folder assembled after the delay. It is the issued set, the notice, the programme update, the weather and the access note — dated, attributable, and still findable when the days are argued.4 Nov 2025 · Learning · Contracts · 13 min read
An adjudicator's dark oak table: a treasury-tagged paper stack showing a weather printout with a rainfall graph, a photograph of a locked site gate, mute programme bars, and red received-date stamps, with a brass paperweight and fountain pen beside it.
Onboarding a subcontractor to your CDE: the first ten daysCDE programmes die at adoption, not at licence.

Ten manila envelopes numbered 1 to 10 hang on a document-control pinboard; day 1 is open with a site access badge on a lanyard, day 10 shows a paper transmittal half pulled out.
Daily reports that someone actually readsA daily report people read cites the issued sheets and gives each field a named reader. Here is the template, and why a diary dump is not a record.16 Sept 2025 · Learning · Field · 13 min read
A one-page daily report with ten short field blocks and a named reader scribbled at the top, lying across a project manager's hotel breakfast tray with toast and tea.
Halving RFI cycle time without buying anythingCycle time dies in three places: an unnamed closer, an incomplete citation, and a query that is not pinned to an issued revision. Those rules run on the register you already keep.9 Sept 2025 · Learning · Field · 11 min read
A document controller in a charcoal jumper writes a named closer at the top of a site-office whiteboard ruled into OPEN, COMPLETE, and CLOSED columns, with handwritten RFI cards citing sheet revisions.
Running a coordination meeting that ends in decisionsTreat the agenda as information design: freeze the issued set, walk clashes against named containers, and leave the room with owners, due revisions and closures — not a slideshow of viewpoints.1 Jul 2025 · Learning · Coordination · 9 min read

Level of information need: specifying enough, not everythingLOD 300 is a geometry slogan. ISO 19650’s level of information need names purpose, objects, geometry, data and documents — enough to decide, not everything the authoring tool can store.17 Jun 2025 · Learning · Coordination · 12 min read

Near-miss data: collecting it so it predicts somethingA monthly near-miss count is a poster.

A British site-cabin cork pinboard under fluorescent tubes: handwritten near-miss cards pinned in messy location clusters, fluorescent lime orange and pink dots marking the groups, dog-eared slips overlapping, no desk in frame.
