Multi-family apartment block

About the project

Tight ceiling voids, repeated floors

An MEP consultant was designing services for a mid-rise apartment block with repeated typical floors and very little ceiling depth. Every corridor carried ductwork, sprinkler mains and drainage in the same zone.

The contractor wanted clashes closed before prefabrication of risers and corridor modules, which meant a coordinated model ahead of the construction programme.

What we delivered

MEP BIM models at LOD 350
Federated coordination model
Weekly clash reports
Coordinated corridor sections
Riser layouts
Builder’s work openings

Shallow ceiling voids
Ducts, sprinklers and drainage competed for the same few hundred millimetres.
Several design teams
Architecture, structure and services changed in parallel.
Prefabrication dates
Riser modules had to be released on a fixed programme.

Our process

From brief to coordinated model in six steps

How the work was planned, modeled, checked and handed over.

01
Brief & standards
Scope, LOD, template and naming agreed at kick-off.
02
Model set-up
Shared coordinates, levels, grids and worksets created.
03
Modeling
Each discipline modeled to the agreed level of detail.
04
Coordination
Federated model checked and clashes grouped by level and trade.
05
Review & update
Comments resolved and models updated between meetings.
06
Issue
Models, reports and sheets issued in the client’s formats.

Our solution

One coordinated model, updated weekly

Typical floors were coordinated first and then repeated, while unique levels such as the podium and roof plant were handled individually.

0+Clashes resolved
0 wksModel to sign-off
0Riser redesigns on site

Typical floor first
One fully coordinated typical floor became the template for the rest.
Grouped clash reports
Clashes grouped by level, zone and trade so each team saw its own list.
Live meeting support
Models updated between weekly coordination meetings.
Builder’s work drawings
Openings through slabs and walls issued from the coordinated model.
