What makes coordination hard in this sector

The cost is in the re-coordination, not the coordination

A core-and-shell design is coordinated once. Then every fit-out re-coordinates the same void against a new ceiling layout, new small power, new terminal positions and a new tenant specification — against a shell that cannot move. The first coordination is a project. The fourth is the same project again with a different architect, and it is where the margin goes. Rule-based checking changes the economics of that fourth pass specifically, because the rule set was already written and the eleventh run costs what the first one did.

Landlord and tenant interfaces are an information problem

The recurring failure is not geometric, it is about who owns what. A terminal unit the landlord installed and the tenant modified, a riser capacity allocated but not recorded, a board with spare ways that three fit-outs have each assumed were theirs. These are answerable from a model that carries system and ownership data on the elements, and unanswerable from one that does not.

Difficulty drivers

Where the effort actually goes

Services density and constraint tightness set coordination effort far more than floor area does. These are the drivers that dominate here.

DriverCeiling void depth

Usually fixed by the shell before the fit-out brief exists, and the single constraint every subsequent coordination cycle works inside.

DriverElement count

High, repetitive and heavily scheduled — which is the condition under which manual checking degrades fastest and rule-based checking performs best.

DriverTenant variation

Each fit-out is a new coordination against an unchanged shell, so the marginal cost of re-checking dominates the total.

DriverRiser and capacity allocation

Shared vertical capacity allocated across tenants, where the record of what has been committed is more valuable than the geometry.

Leading discipline. Mechanical usually sets the void, and electrical absorbs the consequences — but the coordination effort concentrates in the interface between landlord and tenant scope.

Information requirements

What the model has to be able to answer here

Level of information need is a sector-specific question. These are the requirements that are characteristic of this building type rather than generic to BIM.

System and ownership data on every element, so landlord and tenant scope is queryable
Riser capacity allocation recorded against the model rather than in a spreadsheet
Ceiling zone allocation agreed and modelled as a constraint, not as an intention
Fit-out models federated against the retained shell model on every cycle

Automation

Where automation earns its place here

Not everywhere, and not equally. Each line carries its real status.

AppliesRe-checking after changeLive

The rule set that was written for the shell coordination re-runs against each fit-out at a fraction of the original cost. This is the clearest commercial case for rule-based checking anywhere in the sector list.

AppliesCeiling zone complianceLive

Every element tested against its allocated zone, so zone encroachment is a finding rather than a discovery.

AppliesSchedule and quantity extractionLive

High element counts with heavy scheduling is exactly the condition automated extraction is for.

What this page does and does not say. It describes the discipline mix, the coordination character and the workflow fit for this building type. It does not claim completed projects in the sector.

This site publishes no client logos, no project counts and no testimonials, because none have been released and verified yet. If you want evidence rather than a description at enquiry stage, ask for a working session — we will screen-share the rule sets and live QA output under NDA. The projects page explains the measurement rules we have committed to in advance.

FAQ

Questions we are asked at enquiry stage

Do you work on fit-out as well as core and shell?

Yes, and the fit-out case is usually the stronger one for our approach, because the rule set written during shell coordination is reusable on every subsequent tenant at very little marginal cost.

Can you coordinate a fit-out against a landlord model we did not author?

Yes. We check the incoming model's health on receipt and will report where it is not in a state that can be coordinated, which is information worth having early even when it is unwelcome.

Have you delivered commercial projects?

This page describes the discipline mix and workflow fit for the sector. This site publishes no project history until a client releases it, and that rule applies here. If you want evidence rather than a description, ask at enquiry stage and we will screen-share live workflows and QA output under NDA.
