San Antonio Military Medical Center

Exemplary Military Medicine
Managing over 2,000 workers at peak time is quite a feat. I have never seen the effective management of subs executed to the degree of what the joint venture team has done on this job!

The San Antonio Military Medical Center (SAMMC) project is comprised of a 764,000 square-foot medical tower, 358,000 square feet of renovated space at Brooke Army Medical Center, a 1.7 million square-foot, 5,000-space parking structure, and a central energy plant. Clark, in a construction joint venture, completed SAMMC with an impeccable safety record and with no disruption to hospital operations or recovering soldiers.

The consolidated towers project includes:

  • 425 inpatient beds (including 116 intensive care unit beds); 
  • 32 operating rooms;
  • medical, pediatric, and surgical specialty clinics;
  • a bone marrow and organ transplant unit;
  • cardiovascular, maternal-child, and battlefield health and trauma centers of excellence;
  • and the U.S. Army Institute of Surgical Research Burn Center.

To protect the soldiers’ convalescence and shield them from disruptive construction activities, the team enacted a comprehensive noise control plan and took extraordinary efforts to minimize excessive construction noise.

Throughout the project, Clark prepared daily and weekly noise reports, providing information on upcoming construction and the level of noise anticipated. In the field, one team member’s primary responsibility was to monitor the noise of construction activities and to respond to the medical staff’s needs.

When the new medical tower tied into the existing hospital where severely wounded service men and women were recovering after recently returning from the front lines in Afghanistan and Iraq, the team built temporary noise barriers on site to buffer the medical spaces against unwelcome sounds. 

The SAMMC project employed an Integrated Design-Bid-Builder (IDBB) contract, the first of its kind for the Army. IDBB is an acquisition methodology that allows the constructor to interface with the architect of record, the USACE, and end-user groups during the period from design development through 100 percent completion of each work package.


The SAMMC project had nine full-time safety managers and 50 employees doing weekly or daily safety walks at peak construction. Over the course of the project, the SAMMC team recorded more than four million manhours with zero lost-time incidents.


The project team worked closely with subcontractors to plan, monitor, and obtain the LEED credits. Notable sustainable design features include occupancy sensor activated lights, light sensitive control devices, photoconductive controls for exterior lighting, timed switches, and a dual flush water closet with a maximum water usage of 1/6 gallon per flush. The exterior skin consists of terracotta wall panel systems, terracotta baguettes and louvers, exterior sun control devices, structural steel canopy, and a thermoplastic polyolefin (TPO) roof.

Giving Back to the Community

Clark was committed to helping disabled veterans by providing on-the-job employment mentoring for work-ready military veterans. In conjunction with Enable America, a non-profit organization dedicated to helping people with disabilities find employment and live independently, The project team hosted an employment mentoring session for disabled veterans. The mentoring program was designed to give real-life work experience that can lead to employment.
