Project Overview:

This project consists of providing design and construction services to properly ventilate the mechanical and electrical equipment rooms on the B1 level of Building 10A. Significant project features include:

• Mechanical System Ventilation Design: The Design-Build contractor must provide a mechanical system design that provides ventilation to the mechanical and electrical equipment rooms on the B1 Level of Building 10A. The existing equipment rooms include rooms B1-05, B1-20, B1-20A, B1-19, and B1-14. Keel’s Landing surveyed the existing conditions of the space and reviewed the existing mechanical ventilation system to determine what equipment needs to be replaced and detail new equipment requirements needed to properly ventilate the rooms.
• Ventilation Fan Design: Keel’s Landing provided a design to replace (2) existing supply fans, SF-3 and SF-4. Fans selected are direct drive fans, and fan motors are variable speed with VFD or built in adjustable/variable speed. Fans are able to automatically start and stop, and change speed, depending on the room temperature and humidity conditions, fire/smoke control as required.

Project Overview:

At Building 10, CRC, Room 5-3233, the National Heart, Lung and Blood Institute (NHLBI) is replacing (1) and adding (2) additional Bio Safety Cabinets (BSCs).  CNE and Keel’s Landing worked together for design and construction services to provide vacuum line connections to the BSCs and relocate an existing electrical raceway. Design services were provided to determine if the additional BSCs impact the acceptable heat load within the room.

Scope of Services:

This project consists of providing design and construction services to prepare Room 5-3233 for the new layout of the room due to additional BSCs. Significant project features include:

• Vacuum Line Connections for BSCs: Provide a design and construct (2) additional vacuum line connections for (2) Bio Safety Cabinets. Provide proper support for vacuum lines to meet proposed locations of additional BSCs as required.
• Heat Load Design: Validate the existing heat output of the (2) additional BSCs is acceptable for the proposed room and existing HVAC system.
• Electrical Raceway Relocation: Provided a design to relocate an existing electrical raceway that is currently hung from the ceiling.

Project Overview:

This project focuses on designing a system to modify return air handling units (AHUs) across multiple buildings to reduce pathogen spread. It addresses 87 discrete AHUs in Buildings 21, 22, 32, 51, and 66, supporting construction approaches that minimize disruption within these occupied buildings. Each AHU in the FDA facilities at the White Oak Campus is examined in detail. The system, designed and implemented for 87 units and associated ductwork, requires significant modifications based on findings from a comprehensive study on pathogen reduction capabilities. Current guidelines and standards guide the strategies, which include increasing ventilation, enhancing filtration, and integrating ultraviolet (UV) disinfection. The building automation system (BAS) will be modified to allow the UV disinfection and ventilation flushing controls to be enabled or disabled directly from the existing BAS workstation.

Project Overview:

Keel’s Landing provides specialized engineering and commissioning support to the National Institutes of Health (NIH) Office of Research Facilities, Division of Facilities Operations and Maintenance. As a subcontractor, we deliver consulting engineering services on a time and materials basis, with detailed monthly reports outlining the ongoing contributions of our engineering team members, David Carroll, PE, and Douglas Keel, BCxP, MBA. 

Our work includes documenting existing conditions, performing forensic analyses of equipment failures, developing system improvement reports, and designing repair and upgrade solutions with cost estimates. The Keel’s Landing team leverages extensive expertise in the design and operation of steam and high-temperature hot water boilers, chillers, cooling towers, cogeneration plants, pumps, air-handling systems, and plumbing systems. We serve NIH facilities across a range of environments, from offices and hospitals to data centers, laboratories, vivariums, and campus-wide utility systems.

Scope of Services:

As the technical representative for NIH, Keel’s Landing oversees a broad range of functions:

• Conducting detailed analyses of current conditions and identifying system deficiencies
• Preparing construction documents, reviewing submittals, and inspecting work in progress
• Coordinating technical aspects of projects with NIH’s operations and maintenance teams to ensure optimal mechanical, electrical, and plumbing (MEP) system performance

Project Highlights:

• Humidifier Clean Steam Generator Elimination – Building 10C, Clinical Research Center
• Chilled Water Service Upgrade – Nuclear Magneto Resonance Facility, Building 10, Clinical Center
• Reheat Hot Water Pump Replacement – Building 14D, Vivarium Facility
• Domestic Hot Water Return Balance Valve Replacement – Building 10C, Clinical Research Center
• Domestic Hot Water Heater Replacement – Room B1N232, Building 10, Clinical Center
• Heating Hot Water Treatment Replacement – Building 10C, Clinical Research Center
• Potable and Domestic Hot Water Temperature Sensor Installation – Building 10C, Clinical Research Center
• Thermal Mixing Valve Installation – Building 10C, Clinical Research Center

Project Overview:

This project includes comprehensive water parameter surveillance, supplemental chlorination, data analysis, and water safety consulting. Our team conducts quarterly water sampling at over 600 locations, reporting results in Excel for clarity and accessibility. We review and update the NIH Clinical Research Center Water Safety Plan, including a detailed Hazard Analysis, and meet regularly with the Clinical Center Water Management Team to ensure optimal performance. As part of our maintenance, we remove and clean all shower heads and handheld wands, improving water flow throughout the hospital. Patient sectors receive regular flushing as needed. We implement a 60-day supplemental chlorination program for the Clinical Research Center (CRC), maintaining the required free-chlorine level downstream from the injection point to sustain the domestic hot water return. Additionally, we perform all required MDE water sampling and promptly provide results to the Project Officer.
