6 degrees of lab design
Six trends in lab design
1.Keeping costs down
2.Speed of delivery
3.Lab as a recruitment/retention tool
4.Multidisciplinary interaction and collaboration
5.Workspaces moving out of the lab
6.Flexibility and expandability
Relatively speaking, the life-science laboratory market remains rather healthy compared with other sectors of the construction industry. The constant scramble for blockbuster ethical drugs by pharmaceutical companies, endeavors like the Human Genome Project, and the growth of such fields as proteomics and bioinformatics has kept demand for new or renovated spaces rather steady.
Despite this somewhat positive picture, it’s not exactly business as usual for the teams designing and constructing these complex facilities.
Private-sector and university clients are pushing Building Teams to create lab facilities that accommodate both current and future research needs, that encourage interaction among scientists from many disciplines, that help recruit and retain hard-to-get PhDs &M>and, did we mention, to do all this at the lowest possible cost, and at the speed of light? Well, that too.
Keeping costs down
“In the ’80s and ’90s, there were so many blockbuster drugs on the market without competition,” says Stephen Steelman, VP and GM with Dallas-based Turner Corp.’s pharmaceutical division. “Many pharmaceutical companies were spending the money to make a design statement. It was sort of an ego thing.”
One such ego trip was the big, dramatic atrium, a visual signal of a company’s prestige and prominence. In today’s economy, such atria are being reconsidered by budget-conscious clients.
“The basic assertion that good facilities attract good scientists is still there,” says Bill Brader, principal and director of projects with Kling, Philadelphia. “But the idea of having the grandiose atrium is gone.”
Brader says many clients are asking for scaled-down atrium spaces that are also more functional. He describes a recently designed atrium for a 500,000-sq.-ft. lab facility that incorporates offices, program spaces, widened walkways, and a series of pedestrian bridges that encourage interaction among various disciplines in the facility.
“This building joins lab, office, and development spaces, so we used a smaller atrium to bring those different functions together in a community space, as well as to bring natural light into the interior,” says Brader.
Dave Hronek, a VP with Detroit-based SmithGroup, says clients are looking to integrate smaller atriums with a communicating stairway or gathering area. “One client called the atrium a place where they could have group meetings, fundraisers, and even small concerts &M>a space to blend art and science,” says Hronek.
It’s not as if large, dramatic atriums have fallen completely by the wayside. Genentech Hall at the University of California, San Francisco, features an expansive atrium that extends the full height of the five-story building. Centered in the space are a multitude of interaction areas, including a communicating stairway, lounge areas with whiteboards, and open corridors leading to lab spaces.
“People using this grand stair can be seen from the atrium, open corridors, elevators, and interaction lounges,” says William L. Diefenbach, principal-in-charge with Detroit-based SmithGroup, design architect for the $223 million project. “It really creates a sense of interactivity at all levels of the structure.”
Speed to market
Getting new facilities online faster has become absolutely paramount in the pharmaceutical market, where even a few added months of construction time may mean the difference between being first to market with a new drug or being left in the dust by rivals &M>at a cost of billions in sales.
“We used to see occasional fast-track projects, now it’s routine,” says Walter “Bud” Guest, SVP with McCarthy Building Cos., St. Louis. He says fast-track construction starts with analysis of program and design concept alternatives. During the design phase, Building Teams should consider using phased bid packages, an aggressive design schedule, and design elements that speed the construction process.
During construction, Guests suggests purchasing long-lead equipment early, such as autoclaves, sterilizers, and air handlers. The Building Team may want to offer financial incentives to manufacturers and subcontractors to meet shorter delivery times. “We often have the subcontractor prefabricate all mechanical systems offsite,” says Guest. “Then they’re shipped to the site and lifted into the ceiling sections. That saves a lot of time and onsite labor costs.”
The design-build delivery process has become more popular among clients that demand tighter schedules, says Mark Malmquist, a project executive in the institutional group at Shawmut Design and Construction, Boston.
Take Shawmut’s latest project for Brown University, Providence, R.I. Working with architect Tsoi/Kobus & Associates Cambridge, Mass., under a design-build model, Shawmut is converting a 105,000-sq.-ft. manufacturing building into biomedical lab space in just 12 months &M>three months of design and nine months of construction.
“It involves working closely with the architect and the mechanical and electrical subs to make sure we’re all on the same page,” says Malmquist.
Massachusetts Institute of Technology, Cambridge, has also recently converted an existing warehouse-type structure into lab space. This approach saves time, offers potential cost savings in the structural and building envelope, and provides a high volume of open space &M>perfect for the open, flexible lab concept MIT wanted. Malmquist warns, however, that if the old building requires significant upgrades to structural and M/E/P systems, any potential savings may be negligible.
For life-science firms that need space even faster, there are prefabricated modular and portable lab buildings. Companies like Scientific Buildings Inc. of Dayton, Ohio, and Britz Heidbrink of Wheatland, Wyo., offer permanent, semi-permanent, and portable “labs in a trailer.” Britz-Heidbrink, for instance, can design, build, and deliver a modular research building fully integrated with research equipment in just 180 days.
Another option for firms that need to get labs up and running quickly in biotech-heavy cities like San Francisco, San Diego, and Boston is to lease space in a developer-based build-to-suit or incubator lab facility. These buildings are equipped with the basic infrastructure needed to support wet labs. Given the flat office market, a growing number of developers, including Cleveland-based Forest City Enterprises, are flocking to this niche opportunity, hoping to attract life-science firms that don’t have the cash or are not interested in owning property.
The lab as a human-resource tool
Increased competition in both private industry and academia has put a premium on being able to successfully recruit and retain top scientists. To help the cause, some pharma/bio companies are investing in deluxe offices, fancy cafeterias, up-scale coffee bars, and other such amenities.
Millennium Pharmaceuticals’ new seven-story, 220,000-sq.-ft. biology/chemistry lab facility, named 2003 Lab of the Year by our sister publication R&D Magazine, includes a restaurant-style cafeteria, a 24-hour lounge/library with coffee bar, private rooms for dining meetings, booths for small groups, and a food bar to encourage single patrons to make use of the facility. The designer was Elkus/Manfredi Architects, Boston.
Amenities such as a dining facility, a health club, and deluxe office suites &M>each with a research office, conference room, library, and gathering space &M>have helped Stowers Institute for Medical Research, Kansas City, Mo., successfully recruit and retain top talent in the cancer research field to its Midwestern locale &M>not exactly a hotbed for cancer research. The $225 million facility, designed by MBT Architecture, San Francisco (lab planning and tenant improvement), and Peckham Guyton Albers & Viets., Westwood, Kan. (exterior), also includes residential suites for scientists who are being recruited to work there.
Infusing lab spaces with plenty of daylight has also become crucial to attracting scientists. Designers are using more glazed walls and skylights to maximize natural light in these spaces.
“There’s an enhanced awareness of the benefits of daylighting,” says Brader. He says a device called a “light shelf,” which bounces light off reflective ceilings near the exterior of the building in order bring natural light deep into work space, has become popular in lab design.
Genentech Hall has 12x13-ft. floor-to-ceiling windows and sloped ceilings at the perimeter to maximize natural light. The ceiling is pitched from a height of 9 ft. at the interior to 12 ft. at the windows. “We were able to slope the ceiling by tapering the air-handling ducts and other utilities from the core to the perimeter,” says Diefenbach.
Do these amenities actually aid recruitment and retention? Maybe. Officials at the Stowers Institute report that recruitment efforts have been an overwhelming success since their new facility opened in 2001, so much so that the organization is already planning a major expansion.
However, a recent study of 224 scientists conducted by BD&C and RICS, a nonprofit institute serving the real-estate industry, suggests that the importance of such amenities pales in comparison to having top-of-the-line lab equipment and adequate lab space (see p. 53.)
The curious ‘serendipity factor’
Will the next “purple pill” be discovered by two scientists who happen to bump into each other in the hallway? That’s what many pharmaceutical and biotech firms hope will happen, which is why they’re asking Building Teams to create spaces that encourage serendipitous interaction.
Design approaches include placing punched-out alcoves and small gathering spaces in and around main stairways, elevators, atriums, and corridors. At Millennium Pharmaceuticals, office lounges on each floor are designed to bring biologists and chemists together via a communicating stairwell.
At Genentech Hall, each floor has four 12,000-sq.-ft. lab “neighborhoods” with offices, labs, and lab support clustered around an interaction area with a kitchenette, library, whiteboard, coffee bar, and casual furniture. “No matter where they walk &M>from office to lab, lab to support, support to office &M>researchers must walk through this interaction area,” says Diefenbach.
John LaProcido, director of projects with Kling, says some pharmaceutical companies are even teaming researchers with marketing people in lab clusters “because consumer products are so marketing driven.”
Offices coming out of the lab
Pharma/bio scientists are spending less time in their labs doing traditional bench-style research and more time in their offices analyzing data, preparing research reports, or doing e-mail. According to the BD&C/RICS study, computer activities take up nearly 40% of a life-scientist’s workday.
As a result, designers are moving lab workstations out of the lab. Just 20% of respondents to the BD&C/RICS survey said their office space is located in the lab itself. This approach not only saves on lab construction costs, which are significantly greater than office construction costs, but is also safer, says Kling’s LaProcido.
“From a safety standpoint, the trend is to get the people out of the lab and control the amount of flammable liquids in a lab,” says LaProcido. If a facility exceeds the amount of solvents allowed by NFPA code, says LaProcido, then fire-rated solvent storage rooms are required. Just-in-time delivery of chemicals is also an option.
For structures like the seven-story Millennium Pharmaceuticals lab, NFPA code is even more stringent. “Fire departments don’t want high hazards situated in a building where they can’t get to,” says Steve Copenhagen, AHSC McLellan & Copenhagen, principal lab planner on the project.
The Millennium plan divides each floor into two fire areas, separated by a four-hour partition and three-hour doors, thus permitting the maximum amount of chemicals on the upper floors. The lab also has easy-access “safety walls” situated at each lab entry point, where safetyequipment &M>eyewashes, lab coats, glasses, fire extinguishers, manuals, service cut-offs, shower units, and fire-alarm pull stations &M>are stored.
Adaptability and flexibility
Given the rapid changes in life-science reserach, many firms can’t forecast what they’ll be working on in five years, let alone 10 or 20 years. Consequently, designers are being asked to create labs that can adapt to the client’s changing needs.
“Clearly, no building can support every conceivable function,” says Jerry Koenigsberg, retired principal of GPR Planners, Purchase, N.Y. Because most facilities have long-term limitations, such as load-bearing capacity, vibration, cooling capacity, shielding, or isolation, he suggests several keys to designing an adaptable facility:
n Develop a generic lab structure where all rooms are multiples of a universal module in terms of size, shape, and utility requirements.
n Adopt an open-lab approach with limited use of partitions. This allows administrators to adjust allocated space and permits cost-effective renovation work with little impact to adjacent operations.
n Specify flexible casework that can be reconfigured quickly by lab users, without relying on facility personnel. It should also have plenty of load-bearing and vibration capacity.
n Localize lab cooling with the use of chilled-water spot cooling. As more equipment and computers make their way into labs, the heat generated in the space increases dramatically. Auxiliary cooling units located in the lab allow facility managers to respond to future equipment demands.
n Replace central-piped services for gas, vacuum, reagent-grade water, and hot water with point-of-use generators or locally delivered containers. As more lab functions get automated, the demand for higher quality utilities keeps going up. Researchers are turning away from central systems due to concerns over quality and contamination.
SmithGroup’s Hronek warns that, while there may be benefits to flexibility, “you’re paying a premium.” For instance, extensive use of interstitial space to deliver utilities was a common component of flexible lab environments. Today, it’s considered too costly by many owners and facility directors. “We’re going more with generic lab designs that allow users to add additional fume hoods, piped services, and power,” says Hronek. This includes designing larger mechanical/electrical rooms and vertical chases to accommodate future equipment and infrastructure.

Mock-up now and save a bundle later
For scientists and researchers, the look, feel, and functionality of their lab space is crucial , but most laboratory users can’t really visualize space dimensions and layout by reading design drawings, says Walter “Bud” Guest, SVP with McCarthy Building Cos., St. Louis. “Frequently, after lab spaces are constructed, they don’t function as originally envisioned, which can result in costly changes.”
One solution to this problem is the lab mockup. Whether built of plywood, drywall, cardboard, or the real thing, mockups allow researchers to test drive their new lab space before the final nail is driven, when adjustments can be made to the design with much less consequence to budget or schedule.
Guest says that, in the design phase, a roughly constructed, full-sized replica of the lab can be prepared offsite, such as in a warehouse. Its purpose is to convey a sense of the area, layout, and location of workspaces and utility outlets.
A more finished mock-up can be assembled onsite during the construction phase, says Guest. A typical room can be completed with finished materials before work proceeds on the remaining rooms. This allows users a last-chance critique of the space details, such as the placement of lighting fixtures and electrical and gas outlets. “Minor changes can still be made at this point at little costs,” he says.
Mockups are most cost effective for repetitive spaces, such a lab modules or animal holding rooms. But Guest says that no matter what type of space you’re working with, a few thousand dollars spent to create a mockup will help your Building Team avoid more-costly mistakes.BDC

Despite the apparent importance of mock-ups, not all Buildings Teams do them. In a recent BD&C study of 224 scientists, nearly 40% said that mockups were not incorporated into their company/organization’s most recent lab construction project.

Philadelphia-based design firm Kling incorporates animated graphics into the lab design process. The firm creates 3-D models that allow scientists to pan, zoom, and fly through the space, says Bill Brader, principal and director of projects with Kling. “We can not only walk the client through the facility, but also the contractor, construction manager, and even the guy that will be laying the flooring, so they know exactly the kind of quality we’re looking for,” he says.
Tips on commissioning a lab
In sensitive life-science research facilities, even the tiniest alteration to the lab environment can drastically affect research results. In order to prove the accuracy of research results in a new or renovated lab facility, most companies and institutions require a commissioning process to confirm the performance of the lab. When planning for a commissioning of a facility’s structure, design, and equipment, consider the following:
Commissioning plans should start in the design phase.
It’s important for owners to review and share their commissioning requirements during the design stage of a construction project to ensure the Building Team’s plans for the facility match expectations and needs. It’s during the design stage when plans are made to develop systems that are integral to achieving the performance functions needed for research projects.
Be specific about what equipment and areas need to be commissioned.
There are several levels of commissioning, and every item in a facility can be tested through the commissioning process. Therefore, it is important to identify the specific areasand equipment items that require review, to keep costs down.
Commissioning should be conducted throughout the construction process.
Because life-science labs are so sensitive, even the smallest details, such as how windows are sealed, can affect research performance. It is important that these items be individually tested as they are completed throughout the construction process, so potential problems can be addressed before construction continues on other parts of the laboratory.
Owners need to keep everyone informed of changes in their research needs or performance requirements.
Because there are often a number of decision makers involved in the development of a lab, it can take several months for changes in research performance requirements to gain final approval. The owner must let the Building Team know of any potential changes early on, even before they’ve been through the entire approval process. In many cases, the Building Team can modify the construction schedule to work on other areas of the facility while changes are being cleared, eliminating the need later for large modifications to parts of the facility that have already been completed.
