“The Consolidated Forensic Lab is one of the most important projects of my Administration and key to improving the criminal justice system in the District. The Lab will coordinate crime, public safety and health investigations to help law enforcement solve crimes quickly without the need to rely on others and their competing priorities.” —(Former) Mayor Adrian Fenty, District of Columbia

three dC government agencies will share this 351,000 GsF Consolidated Forensic laboratory, combining the functions of public safety and public health into one world-class, state-of-the-art facility. these advanced research facilities will enable the dC Metropolitan Police department, the office of the Chief Medical examiner and the department of Health to provide a broad range of safety and health services to the district of Columbia’s residents. the collocation of the three agencies will improve efficiency and speed the lab-based aspect of criminal investigations, resulting in improved case closure and response to threat identification.

the project includes office space, a morgue and Metropolitan Police department forensic laboratories, as well as toxicology, histology and public health laboratories. according to a security threat assessment of the building, the facility falls under the security level of a Gsa level 3 building. the loading area is on the west side of the building with controlled access for all deliveries, providing security for the facility. Parking is under the building with street parking for visitors.

the program organization and façade treatment are a response to the site and solar orientation. the laboratories are located along the north side, allowing for good natural light without significant heat gain in these mechanically sensitive spaces. building core and laboratory support spaces are located in the center of the building. office spaces are located on the south side with full-height curtain wall to take advantage of the natural light, while exterior fritted-glass louvers provide solar control for the offices. a six-story high edge atrium at the corner of two main streets serves as the main entry lobby and an intercommunicating space for the upper floors. the atrium becomes a beacon and reveals the communicating stair and structure within. shared conference rooms are organized around the atrium. the east and west facades are limestone with smaller punched windows in response to that specific solar orientation. the limestone façade wraps up to the mechanical penthouse roof to become a masonry frame for the whole building, anchoring the southern glass and the northern metal panel skin.

on track to achieve leed® Platinum Certification, all aspects of the design promote science and sustainability. the facility itself is as high-tech as the work being accomplished within, thanks to an advanced thermal wall scheme and an exterior curtain wall, which controls and filters sunlight and promotes natural airflow. the facility’s south-facing louver system will be clad in photovoltaic panels, and enthalpy wheels will be used for Heat recovery air Handling Units. inside the building, designers have maximized opportunities for natural light in both the office and the lab space for a bright and pleasant work environment.

“BIM allowed us the opportunity to actively engage with our clients and develop a real-time highly sustainable design solution that will enhance the productivity and satisfaction of those utilizing the space.” —Bill H., AIA, LEED® AP, Design Principal

“Our client expected the highest level of efficiency and execution in this complex fast-track project. Coordination through the use of our BIM models enabled us to monitor and resolve changes seamlessly in both the design and the construction process.” —Tim O’C, AIA, LEED® AP, Project Manager

the design team consisted of the architect and over 30 sub-consultants who used the revit model in various capacities. three architectural models were shared between multiple offices of the prime architect and the associate interior architect firm. Models were synchronized automatically every night or could be updated manually during the work day as required.

Many of the specialty consultants used the biM model to complete studies and reports for use in the design and permitting/approvals process. examples of studies and reports include:

• Windwake/exhaustentrainmentstudies• Vibrationanalysis• Daylighting• Sitelighting• Atriumexhaustanalysisand• EMI/RFIinvestigationandshielding

Maintaining all datum points and coordinating the different models was the responsibility of the prime architect led by a team in Washington, dC. the lab planning group, a member of the prime architecture firm, performed the lab design in a different office location. their responsibilities included lab planning and programming (including room data sheets and equipment layouts), lab design, integration into the overall blocking and stacking, and documentation of all lab spaces. the interior architect was responsible for the office suites, collaboration spaces, amenity spaces, and furniture/fixtures/equipment.

during construction, collaboration of all major building systems created the biM model. this effort went beyond isolating the above ceiling systems for coordination or detailing the finished for rendering. the design team integrated the mechanical and electrical systems, architectural components, and the structure to determine sequencing implications and identify conflicts. regularly scheduled meetings were held with the respective architectural and design teams along with the subcontractors to address the means and methods of the design intent. this process allowed all parties to visually realize what may not be readily seen on the design documents. adjustments could be made immediately in real time to determine what solutions would work.

“This is a complex and critical project undertaken by the District on a tight construction and activation schedule. There is so much effort being saved on site during the rough-in installation since the conflicts were identified during the coordination process using Navisworks and BIM. Utilizing Navisworks and BIM for coordination enables the mechanical contractor to shop fabricate pipe racks and ducts having the confidence that coordination conflicts in the field will be a minimum. In addition, we look forward to exploring opportunities to use the model for facility operations and management.”

biM was integral to realizing some of the complex façade components. the south elevation has two major systems, an integrated façade of curtain wall and automated solar control louver, and a point supported wall system. the integrated façade began as a closed double skin. after computational fluid dynamics and solar studies were conducted, it was determined that little benefit would be realized in dC’s climate with a closed system. once a louver system was designed, additional studies including printing 3-d models were completed to determine not only the aesthetics of the design but the exact location and orientation to maximize shading and solar control.

the basis of design for the point supported wall system ended up not being selected. therefore, the deflection and interstory differential movement of the selected system were quite different. specifically, the corner condition in the base design required too much movement. Working with the exterior wall fabricator the design team was able to evaluate various options before arriving at a decision. the contractor was able to develop mock-ups for review. all of this was done quickly and effectively with the assistance of revit and rhino.

“Our client, the District of Columbia, has a much higher comfort level that their funds are being spent wisely and cost effectively when the coordination conflicts are resolved by the appropriate team members in meetings where the conflicts can be viewed in the model on screen rather than trying to hurriedly solve them in the field, often without the correct team members present or available to cost effectively assess and solve issues. Using Navisworks and BIM for our coordination was an absolute necessity due to the complicated systems for this critical new facility for the District of Columbia.”

—Jeff A., PE, CCM, LEED® AP, Project Director

From the initial planning stages, biM was used to develop room data sheets and lab standards for the different end users. Conceptual casework layouts were developed and schematic equipment blocks (from field surveys) were placed in the model. the client was able to easily visualize how their space would work. From that point, the individual models populated the block and stack to complete the work flow and process mapping. subsequently, the contractor took the design biM model and completed their casework shop drawings. Using biM was a tremendous asset during coordination allowing for the installer to easily visualize and actualize their work sequence.

“It is much less stressful on the entire construction team, including the contractors, architect, engineers, construction manager and the District of Columbia, to solve the coordination issues in the model on screen rather than in the field where there is usually an idle installation crew waiting to install the work while solutions are developed to solve conflicts.” —Pete M, PE, LEED® AP, Project Manager

the biM model was also highly successful in locating through slab sleeve penetrations, housekeeping pads, fire wall penetrations, concrete slab inserts for supports, feasibility access routing for large equipment, and supports for deck supporting systems before they were congested with above ceiling systems. additionally, the model was used to create prefabrication drawings for rack systems reducing the field labor required for installation. our field forces were able to look at areas of work for planning purposes to realize sequencing for installation.

“This cutting edge technology promotes an opportunity for our field forces to build efficiently by identifying areas in the Navisworks model that may be potential stumbling blocks which can greatly impact the project’s schedule momentum and costs. Critical areas that are unseen utilizing light tables and drawing overlays become obvious and can be addressed to be installed right the first time. The development of the BIM model, integrating the design team, coupled with our extensive experience in laboratory construction is the right approach to plan and build this state of the art facility to maximize the focus on safety, quality, and schedule for a delighted customer.”

desiGn stUdiesFacilities that have a site and program as complex as the Consolidated Forensic laboratory require a lot of time and effort to evolve into the building forms. the site is in a dense urban area with strict zoning and anti-terrorism/force protection requirements. it is adjacent to an elevated highway, elevated train line, and two underground subway lines. the program has a very complex lab program including:

• ABiosafetyLevel3highcontainmentlab• General,isolated,andinfectiousautopsysuites• Indoorfiringrangewithammunitionstorage,firearmsreference library,andbulletrecoverytank• Druglaboratoriesand• ScanningElectronMicroscopelabs

biM was integral to moving the complex pieces of the program into the strict zoning and anti-terrorism/force protection envelope to develop the blocking and stacking for the building. From there, multiple design studies were completed in biM to develop the skin and exterior fenestration. studies were presented to the owner and Mayor of dC using images developed from the biM model. these images were then used to get local and federal approvals for the building.

“The Navisworks model allowed us to visualize the conflicts and therefore helped us provide more comprehensive solutions.”

due to restricted floor-to-floor heights, tight urban constraints, and a fast-track schedule, biM was a critical component to maintaining the project budget and schedule. While the 1st district Police station was being razed and excavated, the structural and mechanical/electrical/plumbing coordination was well underway. the entire team worked their way up the building, sleeve and penetration drawings were prepared and implemented as concrete was placed at a rate of over 1,000 cubic yards/week. alternative design solutions were evaluated to facilitate construction while maintaining design intent. as clashes occurred, snapshots could be distributed quickly and web-based meetings were held to show and walk through the actual model.

the model is currently being used for fabrication. Many components can be prefabricated in the shop and brought to the site to be erected dramatically saving time and money while maintaining quality.

“It is a proactive approach to build electronically first so that our coordination team can prepare sketches and renderings to enable timely and focused decisions by the design team and or our client, the District of Columbia. The process encourages a collaborative effort between the drafting/coordination teams and the design teams to resolve spacing conflicts before the equipment, materials, and systems are procured. As a project team, we benefit significantly with respect to schedule and reduce costs having the confidence that most of the potential clashes are identified and resolved.”

“Using Navisworks and BIM for coordination on this project aided our team in identifying critical controls, serviceability, access concerns and coordinate between the numerous pieces of equipment. The model supported the subcontractor and design teams coordination meetings for the proper analysis of problems and allowed for practical solutions to unforeseen problems. The structural, architectural, mechanical, and electrical components were integrated to anticipate components that are adjacent, layout the connections, and determine absolute tolerances for the various components.”

three models were used during the design of the project; architectural, laboratory planning, and interior design. the architecture model served as the host for the others and was used as a reference to accurately coordinate the different systems used in each model. Concurrently, the architecture model was referenced into the models of the lab planners and interior designers to identify the extent and ownership of each design teams work.

at the beginning of the project and at each milestone, the design team and biM managers (local and corporate) sat down to discuss the critical protocols for the next phase of the project. For example:

• Determiningthecorrectmodelbreakdown• Settingworksetnomenclature,and• Identifyingtheresponsiblepartyforthatparticularpieceofthemodel

each subcontractor was responsible for their individual model. these models were created in autocad, revit, and other 3-d software packages. the models were then compiled by the general contractor to run clash detections.

“BIM is an important tool for the success of this fast track project. Knowing that the mechanical, piping, and electrical systems can be prefabricated supports efficiency and site logistics concerns so that as soon as racks are delivered on site they can be immediately installed in its proper place. On the field level, our foremen are able to visualize spacing constraints to identify phasing plans and study the means and methods of their installation in tight spaces.”

the design architect used an automated file transfer process that assured both the architectural team and the lab planning team were working in the most current version of the model. internal models were exchanged daily while subconsultant models were exchanged weekly throughout the design and documentation process. additionally, remote access to the architectural model was also provided through a remote desktop application that allowed off-site team members to access the central revit model for reference or even to make changes as needed.

When construction began, the contractor and sub-contractors met every week to review progress and clashes. each sub-contractor posted their most current models at the end of each week so the general contractor could compile them and run clash detection.

additionally, multiple teams working on different floors were able to expedite the process and keep up with the site, civil, and structural progress.

Communication, Collaboration, and Contribution are three fundamental factors to successfully design and construct a project of this complexity. Given the fast-track nature of the Consolidated laboratory Facility project, the design and construction team needed to work together in the most efficient and effective way possible. the use of biM contributed to the project’s success by making it easy for all parties to constantly be in communication and proactively problem solve throughout.

CoMMUniCationthe design teams met regularly to review the model and coordinate with all of the disciplines involved to successfully accomplish the design objectives. the model was presented to the owner and used as a visual aid to obtain user buy-in and approval. since the beginning of construction, the owner, design team, and contractor have weekly meetings to review the coordination progress and proactively resolve conflicts and potential clashes.

Collaborationalthough the Consolidated Facility laboratory is not a true integrated Project delivery project, biM allowed all parties to work closely together within the design-bid-build procurement method. all parties involved came to weekly meetings to work in partnership to keep the project on time and on budget.

ContribUtion Perhaps the most telling attribute of the successful use of biM in this project is the deeper appreciation and understanding each party has of each other’s role and how their own contribution benefits the overall success of this project. through this joint participation, all parties felt an increased ownership of the project and proactively came to each meeting with solutions.

“We [The Mechanical Contractor] have been implementing a process that is now described as the 1st Generation of BIM, a 3D Coordination process, for the past 10 years. The Coordination processes require an object oriented 3D model be produced for spatial coordination and the development of fabrication spool drawings. When required, we have developed Structural and Architectural elements of highly congested areas to assist us in resolving coordination conflicts. With the adoption of the BIM process becoming more commonplace in the A/E segment, more advanced and detailed CAD files are now available for our use on many projects. Five of our Coordinators are classroom trained in the most widely used BIM software, Navisworks Manage.

Our purposes for utilizing a BIM process are twofold: 1. Generate Spool Drawings for Fabrication2. Reduce the number of Field Observed Conflicts and Field Generated RFIs

As the cost of Labor increases, and project durations and schedules decrease, prefabrication of piping systems and components into installable “assemblies” reduces the required number of field personnel.

The utilization of a BIM Coordination process has allowed for the resolution of many of the conflicts and collisions that are not discovered in a “light table overlay” coordination process that are then found during the installation of work. These issues resulted in ‘lost’ and non-productive work days prior to the BIM Coordination Process, impacting the project schedule.”

—Coordination and Engineering Manager Mechanical Contractors

QUantiFYthe quality of the schematic and photo realistic images from the biM model enabled the project to move through the design approval process with very few impediments.

the contractor is already five days ahead of schedule within the first quarter of the construction schedule.

the original design estimate was $165 million versus the actual contract value at $135 million resulting in a savings of 19%. Part of this was due to the ability to shorten the schedule by 6 months.

energy modeling achieved 26% energy reduction over the asHrae 90.1 standard.
