Leadership in Data Centre Design



Qatar is different...

• Approvals, approvals, approvals...!

• Format, specific requirements and 2-d

deliverable

• Contractor adoption of BIM

• Common consistent platform for data sharing

• Little BIM – BIM not client requirement

Design Team only used Revit so not BIG BIM...

Handover methods



Desert Data Centre Design;

• ASMEP disciplines on Revit platform

• AutoCAD cuts and development

for details and approvals

• Through the design process...



Tender Issue:



• Early stage design

• BIM process with many software tools

• Example of optimisation

• Parallel to BIM model

Optimisation of Data and Building

Typical pressure

distribution under a

raised floor

Optimised air flow



Optimisation of Data and Building

• Above floor airflow management

:

Typical problems with open frames

– Open network frames cause breakdown of the

Hot-Aisle/Cold Aisle concept.

– Hot exhaust air from server racks recirculates

around the network equipment causing

overheat.

New layout

– Hot exhaust air from server racks is captured

by ceiling plenum.

– Network equipment in open frames is cooled

successfully.

Initial Studies:

For space

planning and

building form.

Revit dynamically

reported the room

properties for

outline MEP calcs

and to minimise

the building

footprint.



Concept Stage

Creation of new

families of content,

working with

CIBSE and other

industry bodies for

consistency



Concept Design Stage

Upload content through the Family

Browser.

This contains “Controlled” and

“Uncontrolled” Families.

Personalised content to share with team



Revit challenge;

To make objects

look like traditional

drawings for

approvals etc….!



Design Development – added detail and embedded data



Design & Documentation – Schedule driven analysis



Design & Documentation – Graphical system checking



Design & Documentation – System properties



Design & Documentation – Drawing presentation



Design & Documentation – Graphical display of room data



Coordination – 3D maintenance strategies



Data Centre in the Desert

Summary

•Revit used for ASMEP design development•Now on site with the contractor using 3-d model too•Benefits to the project with better coordination with

scheduling and design data flow•Approvals unable to use the model•2d deliverable produced and Revit model unused beyond

design•A better building!!!

The future....?
