2nd Qatar BIM User Day Case Study #1

Data Centre in the Desert
2nd October 2012

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...

Desert Data Centre Design;
• ASMEP disciplines on Revit platform

• AutoCAD cuts and development
for details and approvals
• Through the design process...



Tender Issue:



Optimisation of Data and Building
•

Early stage design

•

BIM process with many software tools

•

Example of optimisation

•

Parallel to BIM model

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

Cold

– 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....?
