EC · Research method

ECFrom desiderata to a defensible decision.

EC research does not transcribe a preference: it converts it into requirements, comparable alternatives, reasoned recommendations, and verifiable gates.

Public research edition

Method and status are public; the technical file remains controlled.

These pages do not authorise work and do not replace surveys, calculations, filings, works direction, safety coordination, or professional signatures. Internal PDFs become downloadable only after publication review, restricted-data removal, and entry in the controlled manifest.

Eight stages

Research first, issue only after checks.

State the desiderata

Record the requested outcome, reason, constraints, budget logic, and decision owner without presenting them as measured facts.

Build the evidence register

Separate measured, documentary, user-proposed, inferred, professionally assessed, approved, and as-built information.

Define performance

Translate the request into structural, moisture, thermal, acoustic, fire, durability, accessibility, maintenance, and reversibility requirements.

Research the current framework

Check primary technical and institutional sources with access dates, jurisdiction, edition, and applicability limits.

Generate viable options

Develop a minimum intervention, balanced intervention, and higher-performance route where the evidence allows meaningful comparison.

Compare and recommend

Compare risk, performance, compatibility, carbon, disruption, maintainability, approvals, programme, and whole-life cost; expose uncertainty.

Pass professional gates

Freeze no design value, permit route, safety measure, or execution issue until the competent appointed professional has accepted it.

Verify and learn

Record inspections, tests, variations, commissioning, costs, defects, maintenance, and as-built evidence so the next project improves.

Comparison matrix

The optimum depends on real performance and constraints.

Life safety, structural reliability, temporary stability, fire, and safe maintenance access
Moisture, thermal continuity, indoor conditions, durability, compatibility, and inspectability
Heritage character, reversibility, material conservation, visual impact, and planning constraints
Embodied and operational carbon, waste, local supply, construction disruption, programme, and whole-life cost
