Reference tools & certificate base
Max Zs, RCD times and BS 7671 Amendment 4 references are live. Certificates are the product base; wider certificate breadth is still under review.

The work around the work is becoming automated.
Construction operations automation. Starting with UK electrical contractors.
Construction is physical. The admin around it is mostly information.
A distribution board starts as design intent, then becomes priced scope, installed work, test evidence, a certificate line, an O&M entry, valuation evidence and a CDE submission. Today, each stage often rebuilds the same facts in a different system.
The board is physical. The work around it is information.
Design intent should carry through the whole job.
Describe the object once: board, circuit, device, cable, location, standard, evidence. The target is for that object to feed the estimate, certificate, O&M, valuation, document register and handover pack. Assistive workflows move repeatable data. The human keeps control of judgement, approvals and relationships.
What exists. What we're proving. What still needs building.
Prekon is being built in public: useful tools first, role-level proof next, platform claims only where the work exists.
Remedials & estimating
EICR-linked remedials and estimating are in planning, prototype and source-evidence work: observation-to-quote logic, costed circuits and labour hours as the platform asset.
Planning/prototype Readiness to verify
Job descriptions to workflows
Real construction roles broken into tasks, costed, scored, then mapped into workflow experiments, approval queues and possible tool-using agents. Document Controller first.

Construction operations layer
The north-star platform position: design, estimate, certs, O&Ms, document control, payments and handover over one project model.
Electrical wedge Construction category
Construction roles, rebuilt as workflows.
We take real job descriptions, separate repeatable information work from human judgement, then build the automatable parts in public.
The Electrician Is Safe. The Work Around Him Is Not.
The opening argument for the whole series: construction's physical work remains human; the repeatable operating layer around it is exposed.
Read the foundation pieceDocument Controller, Estimator, Designer, QS, PM, Certs.
Role by role, task by task, with cost, benefit, failure points and practical workflow experiments.
