Alta Bates Summit Medical Center: BIM and Integrated Project Delivery

From logistics planning for a congested urban site to constructability analysis of a complex rebar design, the $289 million, 13-story ABSMC patient care pavilion in Oakland, CA., is anything but routine for the project team.

Much of the ABSMC foundation design was based on decades old as‐built drawings from the existing buildings. During demolition and excavation, the team discovered many unforeseen conditions and inaccurate dimensions. Using BIM, robotic total stations and laser scanning technology. The project was modeled in Tekla to begin construction and to support multiple site coordination tasks including shoring layout, clearances to overhanging buildings, MEP/FP systems and optimizing foundation pour breaks. Since the ABSMC site has a zero lot line and connections to the surrounding buildings on three sides and at seven different levels, the project team used Trimble Robotic Total Stations and laser scanning equipment, integrated with Tekla’s Construction BIM solutions to coordinate easily and effectively.

Contractors for the ABMSC project began drilling piles in January 2011 with a 31-day schedule delay due to permitting, weather and unforeseen site conditions during demolition. With extensive collaboration and the ability to react to field conditions using BIM, the project team made up all 31 days of delay before the start of steel in October 2011.

Project Summary:

> Modeled by: DPR with an Integrated Project Delivery Team of 12 partners
> Worth: $ 298 Million
> Seismically safe, modern building housing over 200 licensed beds and 13 stories.
> Complete in early 2014


Alta Bates Summit Medical Center Patient Care Pavilion was the BIM category winner for the 2011 Tekla North America BIM Awards.

"The use of BIM at the Alta Bates Summit Medical Center project has become more than just a benefit “ it has become a necessity." - Nathan Wood, Project Engineer, DPR Construction

Watch our Webinar to learn why DPR Construction chose Tekla's Construction BIM software to support coordination, site logistics, pour management and layout processes on this $289 million, 13 story hospital project.

Join the webinar to hear DPR's Nathan Wood describe how Tekla's Construction Management and Modelling software enabled them to overcome the project challenges and recover 31 lost days over 10 months.

You'll learn how DPR uses Tekla's Construction BIM solutions to:

  • Create and use constructible data to plan and manage their BIM process
  • Satisfy the stringent seismic design requirements set forth by California's Office of Statewide Healthcare Planning and Development (OSHPD)
  • Operate more effectively on a congested urban site
  • Use Tekla and Trimble's integrated solutions to ensure what happens during coordination happens in the field and to capture true site information
  • Conduct constructability analysis of MEP, a congested rebar design and structural steel
  • CIP Concrete planning, quantity take-off and pour management
