Battling the complexity of designing government facilities

The government can be a tough customer, and the projects that state, municipal, federal, and military entities approach engineers about are highly complex. Here, engineers with experience tackling such tall orders offer advice on how to execute successfully.

CSE: What's the No. 1 trend you see today in the design of government, state, municipal, federal, and military facilities?

Raymond Krick III: The No. 1 trend in the design of government projects has been the shift from design-bid-build projects to design-build projects. While the design-build process presents its own issues, a single source of procurement can save the government time and money and allows agencies to award the project to a team as a package rather than sourcing each component. Having an integrated design team from the start also ensures that the project's scope of work is not lost in translation.

Rick H. Troberman Jr.: In my opinion, the No. 1 trend in federal and military facilities are energy and sustainability requirements with ASHRAE 189.1: Standard for the Design of High-Performance Green Buildings, LEED certification, and U.S. Army energy-reduction mandates.

CSE: What other trends should engineers be aware of for government, state, municipal, federal, and military facilities in the next 1 to 3 years?

Lindsay Zanders: One major initiative for military bases is becoming independent of the power grid. This involves a combination of a substantial decrease in energy reliance through highly sustainable design and the production of onsite power. Operating independently from the grid allows these facilities and military bases the ability to operate during a catastrophic state of emergency.

Troberman: The design-build acquisition method appears to be a highly preferred contract vehicle for many federal and military facilities. This vehicle can be an advantageous contracting method for government agencies, as it results in the management of one contract as opposed to multiple contracts to complete a project. BIM is another trend that federal/military government agencies are picking up. Many solicitations are starting to use phrases such as "highly preferred" regarding BIM services and even requiring BIM design and submitting the BIM model to the to the owner for their use. Agencies are starting to see the value in this and are paying for this service.

Krick: With the recent boom in smart technology for the residential sector, government, state, municipal, federal, and military facilities will place a bigger emphasis on controls and integration. As the popularity of retro-commissioning grows, we will see more implementation of the latest controls and control strategies into existing systems as a means for energy savings.

Zanders: We currently are tasked with mechanical, electrical, plumbing, fire protection (MEP/FP), and lighting design for the renovation of the U.S. Marshal Office in Chicago's business district. The office occupies the 24th floor of the Mies van der Rohe-designed Dirksen U.S. Courthouse building. As a protected landmark building, the team is prohibited from modifying any perimeter system appearance including fin tube radiators (FTRs) or lighting. The team employed creative mimicking solutions to meet federal design and energy requirements, such as LED tube retrofits. The original hot deck/cold deck with localized mixing-air boxes was converted in a previous project to 100% cold supply, since perimeter FTR met the heating demand load. The team added variable air volume (VAV) boxes and thermal registers to provide thermal control to individual spaces. The U.S. Marshal space houses administrative offices and conference rooms, physical and educational training centers, a central command center, and prisoner detention. The detention element became the critical element for both secure design and construction phasing. Security and safety are the top goals. As a result, operations centered on the prisoners must remain in service throughout the project; therefore, complex phasing of holding areas and secure pathways was generated. Though the high-rise building houses a number of other government agencies with independent functions, the HVAC and electrical infrastructure are shared among all of the tenants. Primera's challenge was to design modifications to the space with no or minimal disruption to the other spaces also served by the same MEP infrastructure.

Troberman: We are currently in the construction phase for an unaccompanied enlisted personnel housing (UEPH Barracks) project at Joint Base San Antonio-Fort Sam Houston located in San Antonio. We designed an HVAC system comprised of 100% dedicated outside-air units (DOAS) with energy recovery along with variable refrigerant flow (VRF) systems for local zone heating and cooling. This project is required to achieve LEED v2009 Silver certification. The project was also designed using BIM.

Krick: We recently completed a successful lab renovation at the National Cancer Institute in Frederick, Md. The facility has 2 floors of laboratories and an attic that houses its mechanical and electrical equipment. The renovation included a full replacement of the MEP systems serving the first floor and phasing to keep the second floor operational during construction. Among the major challenges were adding redundant systems in the already cramped existing space and maintaining the operation of the sanitary system serving the second floor while the complete subslab piping system was removed and reinstalled.

CSE: Describe your experience working with the contractor, architect, owner, or other team members in creating a BIM model for such a project.

Troberman: The architect on the barracks project created the base building model and then incorporated the other disciplines' models into the master model. The architect was responsible for managing updates, and all disciplines were responsible for using the most updated model to incorporate their respective updates. BIM was very useful on this project because we were constrained above ceiling and the government had very specific standards for clearances. We used the BIM model to drive decision making during design so that we could identify the best systems for that exact space. The project is currently in the construction phase, and we are now seeing the success of BIM in that the constructability of our design is of a much higher quality, minimizing clashes. Additionally, when I was a mechanical engineer with the Army Corps of Engineers and worked on a large hospital project being built in 2010, a significant effort was put into clash detection using BIM, and the value of this was fully realized during construction.
