Harnessing BIM Technology and Integrated Project Delivery for Sustainable Design
Technology meets sustainability: Texas Children’s Hospital’s West
This is a case study about a project in design where technology and sustainability has been integrated. The way how the speaker talk captured ones attention at all times. It was a very interesting conference. Below is the summary and notes of what occur. Feel free to post comments
The Texas Children’s Hospital is the largest children’s hospital in the USA.
It has been consistently ranked in the top 5 pediatric hospitals nationwide.
Vision 2010 is adding over
1.5 B in new facilities
BIM and sustainability doesn’t seem to go together, but they do in this project.
How do we use the computer to help design our buildings?

The Texas medical center history
TCH opens in February 1954 with 106 beds
First expansion 1968- Got expanded and connected to another building.
Expansion of 1991 included, research building, west tower expansion. Old building is hidden from the new copper champaign glass building
Expansion of 2001- In the west tower and added new clinical care center.
City of Houston
West side of town. New campus (part of the program vision 2010)
TCH west Houston campus- 55 acres, next to the Methodist hospital of 80 acres
Both being constructed and design by Page Southerland Page.
What is happening for the 2010 expansion?
TCH maternity center
Feigin center expansion
Neurological research institute –by Perkins and Will
City of Houston- All the growth of the city is towards the west and there is plenty of room to grow unlike to the east since there is the bay and refineries

Construction costs history-
40-70’s – 5%/yr
60-85’s – 7.75 %/yr
85-04’s- 2%/yr
04’-07’s – 8-10%/yr
If you delay a project by a month that is a million dollars, just by the escalation.
How do you estimate and approach a project?
Therefore when one talk about a budget one should not give a number any more but show a graph that shows the changes ad predictions of costs pricing.
‘’Tell me when you want the building done and then we can talk how much it is going to cost.’’ After that statement the client wants it done as soon as possible.
-Project schedule-
Where we’ve been; were we’re going?
Fast track, multiple bid package CM at risk
Fall 07’- programming and master planning
Winter’07- CM pricing, VE/redesign, Approvals
Redesign because the costs were so much higher that some things needed to change.
Lots of expectations and keep the building smaller. Good lesson learned.
Spring 08’= begin multiple bid packages
Site and foundation (full building)
Superstructure (full building)
Central plant
Core and shell-ambulatory wing
Core and shell- hospital wings
Build out – ambulatory wing
Build out hospital wings
3. Building Information modeling
-Owners perspective-
Interested in using technology
BIM as an ongoing facilities management opportunity; believes there will be long –term benefits
No direct BIM experience; sought a design team with pertinent BIM experience
A/E firm experienced in a committed to BIM
Long time use of Autodesk architectural desktop
Growing experience with REVIT
-WDC office first to switch to all Revit; very pleased, not looking back
Pilot teams in other offices, on large and small projects
Building families (symbols) to match existing standards
Commitment to BIM and Revit
Dedicated BIM advocate/trainer
BIM: architects perspective
BIM is not Revit or Archicad or Navisworks. A building information modeling significance is less the 3d model than about the unimpeded flow and exchange of digital information.
-Typical A/E document process today-
Phase-
Strategic planning/business case
Programming
Design
Shop drawings
Maintenance
Renovation needs
Typical working materials-
Spreadsheets, document files, presentation files
CAD files and BIM FILES (for the digital)
Project schedules
CAFM, computerized maintenance mgt system
Typical deliverable-
Bound paper document
Paper plans and specs
Printer work orders
When it was all paper there was no big of a deal, but now everything should be digital? Do you think so??? The basic flow of things should not be paper anymore.
We use the spreadsheet as the base of it.
Ad HOC analyses to help the client how many sq ft per room, etc to form decisions that happen during program, are much better done through a spreadsheet.
Room data sheets. Reports
Here flow starts in programming
Adjacency diagrams-
Bubbles linked to space list; always to scale
Stacking diagrams – blocks linked to space list; always to scale.
Live what-ifs
Team coordination-
Using 3d bIM-
Architect (Houston and Dallas offices)
Structural engineer
MEP engineer
May or may not use BIM for this project
Food service, security, landscape, furniture
Early meetings to exchange lessons learned and establish protocols and standards
Split the project into appropriate sub-models (lesson learned)
Questions? Kurk Neubek speaker
How are they paying for this?
When they split the models, does that have a geometric effect. Do they have to compare one model with another?
One needs to split it in a space that makes sense, by discipline or something where it can be overlaid. They can take multiple models from different software’s and put them together.
Is it a complete stand alone facility?
It was an important part of it, there is demolishment and then the other hospital next door that are coming up at the same time. Therefore they share a tension pond and other services such as loading dock, where discussed.
One needs a model that is valid in 3d and information that one will be able to open it in different programs.
The entities are known what they are.
In Revit every thing has parameters.
Then it can be located dimensionally and so you can actually have the floor plates and know where the bolts are.
What is the interface and what is the reaction in governmental?
Architectural drawings can look pretty conventional.
He could not tell they were in Revit, since one still needs to show floor plans, ADA, fire codes and meet all the requirements you need to meet.
4. Sustainability
Wants
To do the right thing
To be responsible and good stewards
A wealthy building on a fixed budget
LEED certification is not the most important thing
TCH is already committed to commissioning, so those credits should not be counted as a cost of Leed.
What is the cost of getting leed certified?
They already have hired a person to do commissioning; therefore don’t count that as a premium.
It makes the so called Leed premium small.
There was discordance between a member in the audience and a speaker.
In order to show if there are getting the Leed point they have to get that analysis
There is a prescriptive portion
How is the building going to be crafted for it to be sustainable?
Energy performance
As far as good practices
Aware of western sun
High performance glass
Meet energy codes
Where are the overhangs
They don’t have to do an energy model to do that they know it by heart.
Simple tools are not expensive to do, so it’s a lost opportunity since they did not use them.
The building could have rotated a little bit if they use that, but the energy model would get into the shading coefficient and the overhangs.
Architects perspective
Initially tracked both Leed-NC and the green guide for healthcare
Now primarily following Leed
Anticipated Credits
9credits sustainable sites
2-5water efficiency
4-7 energy efficiency
7-10 materials and resources
6-12 indoor environmental quality
Therefore if everything is done well the building should be at least ‘Leed certified’
Which ones comply with known TCH standard?
Deviate from known TCH standard
Deviates from TCH standard first cost impact hich
Target
Questionable credit
Not a target credit
The ones in the middle are the ones they have to work because they might get them.
Suburban center
Good because people hate the med center. No parking and expensive
Open space should be done.
Light pollution reduction
Water efficency
Optimizing energy performance
If you use the building as a demonstration facility?
If you commit to green housekeeping practices?
There are things that are recognized in some systems so then you can use them somewhere else.
Innovation points are good for the environment but the threshold between each point is difficult and you have to be able to meet that.

Consultants were not forced to go the BIM route in this project-even though the design team is. This brings up a good topic—how do we get everyone involved to jump on the BIM bandwagon?
