Lab and Research – Phased Commissioning Services SEA resolved historic and ongoing building systems operations through a phased commissioning approach within six weeks – resulting in optimal conditions for the forensic lab. About the Facility The Robert Clinton Hatch Hall Forensic Sciences Building is shared by the Alabama Department of Forensic Sciences and Alabama State University (ASU). The 50,000 square foot, eight year-old facility incorporates state-of-the-art forensic science laboratories, computer labs, a mock courtroom, instrumentation laboratory and a criminal logistics laboratory for instruction in techniques used to examine evidential materials. Challenges Facility owners were specifically concerned with the operations related to the forensics lab spaces. Overall, the building was allowing substantial amounts of water infiltration during rain fall and the current HVAC system was unable to provide a positive pressure environment. Additionally, the facility’s temperature and humidity lab requirements were not desirable and coordinated air space was inconsistent. Because of these issues, the forensic labs were experiencing a high concentration of airborne fungi particles. Any one of these issues could greatly impact and compromise forensic testing. It was important to determine and resolve root causes quickly so as to not impact or delay lab testing. Scope of Work To achieve overall building success, all systems needed to operate optimally. Ongoing preventative maintenance of the building envelope and the HVAC system also needed to be consistent. SEA was hired to quickly implement a phased commissioning process and worked to develop contract documents for system repairs and replacement. SEA also ensured that all building systems were operating optimally during the construction phase. The commissioning activities were broken down into four key phases. Phase 1: The team worked to investigate all systems and conduct control assessments. This included Testing, Adjusting and Balancing (TAB) the Chiller and ASU – resulting in an Investigative Report. Phase 2 : In this phase, the SEA team defined the necessary solutions for all of the operations and worked to rewrite code controls. This documentation included a master schedule, costs analysis and responsibility matrix. Phase 3: SEA worked to upgrade controls and make all final repairs with additional TAB measures. Phase 4: SEA provided the final commissioning report of all activities conducted in the previous phases and included a roadmap for future operations and maintenance. Download Project Profile

Retro-Commissioning Services SEA resolves humidity issues for unique structure and provides necessary documentation for future operations and maintenance. About the Facility J.B. Taylor Diagnostic Laboratory (Elba Labs) is owned and operated by the Alabama State Department of Agriculture and Industries (ADAI). The lab provides a wide range of regional diagnostic services for Alabama livestock and poultry producers. Occupied in 2005, the current building was experiencing difficulty controlling humidity 15 years later. The building consists of two areas, a lab and conference area. At A Glance 50% Targeted Site Humidity 15 Years – Age of Infrastructure 10k Square Feet Scope of Work Sain Engineering Associates, Inc. (SEA) was initially engaged to evaluate the existing building’s HVAC and controls, building automation system and envelope to identify the cause of the humidity problem. The desired result was to maintain and enhance predetermined air flow quantity in the appropriate direction between the adjoining lab and office spaces. One of the early challenges faced by the team was the lack of documentation supporting existing systems on-site. Additionally, many of the parts needing repair were no longer available. SEA’s Commissioning Provider (CxP) not only conducted the necessary assessments to determine and resolve the issues, but also worked to provide documentation of the systems for assisting with ongoing operations and maintenance. SEA began its work with an initial review of what few design drawings were available and toured the facility to gather historical information pertinent to the evaluation. Initial review of the HVAC and controls system revealed that the operation of the boiler, Phoenix Air Valves (PAVs) and reheat coils were no longer reliable or effectively controlled. Numerous PAV control components had failed and were being set manually as an interim measure. Additionally, the boiler had been offline for some time causing loss of reheat and resulting in abnormally cold discharge air temperatures and condensation on ductwork, grilles and registers. SEA collaborated with the PAV support representatives to: Perform a comprehensive condition assessment of each air valve and its controls, taking corrective measures where feasible Develop a course of action to restore and correct air valve controls and operation Provide recommendations and budgets for PAV control replacement As a result, the following items have been completed: Replaced PAV controls and reheat valves, strobe exhaust fan controls and damper actuators, air handler discharge and temperature sensors to return airflows to design values Installed a Java Application and Control Engine (JACE) to interface between the PAV controls and the BMS, a control point to cycle power, 12 additional VAV DAT sensors, as well as a sensor to the air handler to indicate preheat leaving air temperature Relocated the outdoor air sensor, adjusted BMS controls and tuned the PAV system; cleaned strainer on heating water pump This initial work has resulted in well controlled humidity of 40-50% within the space, even when outside relative humidity is at 100%. Commissioning repairs also greatly reduced the need of repeated support calls. Additionally, SEA has continued to support the owner with project management activities and the creation of documentation required for preventative maintenance on key elements and systems.
