The university needed a way to prevent smoke from traveling between floors through the grand atrium of a four story building. In order to achieve this, the general contractor recommended using a horizontal shutter to create a vertical shaft separation between floors. The custom shutter includes a proprietary smoke management system that prevents smoke and fire from taking over the entire building.

Over eight tons, the shutter is 20 feet wide and deploys horizontally 63 feet to create a smoke-proof barrier between floors. Each 8-foot track segment weighed in excess of 600 pounds. Despite its size, the unit must always be referred to as a shutter. This is so it is never confused as a floor door. Floor doors are used in similar horizontal applications. They can withstand the weight of people walking on them, like firefighters for instance. A horizontal shutter is not intended to support the weight of people walking across it.


DH Pace teams from multiple locations worked together to perform the installation and rigging. As you might imagine, installing a 17,000 pound door wasn’t easy. First, four levels of engineering specialists had to sign off on the installation plan. After the plan was finalized, DH Pace put it in action. They modified the dollies to reduce point loads on the floor, expertly rigged the shutter and positioned the unit to be hoisted.

The entire installation went smoothly. To the delight of the university, the shutter and smoke management system passed fire inspection. From start to finish, the installation lasted approximately ten days. This is another example of how DH Pace manages complex projects across multiple locations with combined expertise.

DH Pace Helps Hospital Meet Door Code Requirements

Category: Inspection and Maintenance
Products: FireCheck® Program
Industry: Health Care
Application: Inspection Services and Code Compliance


A not-for-profit health care network with over 550 beds wanted to meet door code requirements for The Joint Commission, also known as (JCAHO) accreditation.

National Fire Protection Association (NFPA) standards require building owners to have rolling, sliding, and swinging fire doors inspected and tested annually. NFPA standards also require to maintain written
documentation of such inspections.


In a previous year, the health care network performed a fire door certification inspection. In it, they found that most of the openings failed to meet NFPA 80 standards.

The following year, the customer wanted to re-inspect the doors. Knowing that doors that did not meet quality standards threatened their accreditation with The Joint Commission. The Joint Commission accreditation and certification is considered a quality symbol that reflects on an organization’s commitment to meet specific performance standards. Failure to maintain accreditation can result in a loss of federal funding and bad publicity, which can negatively affect their reputation in the community.


The medical center enrolled in the FireCheck® Program to identify all openings that did not meet the standard requirements. First, DH Pace met with the facility’s representatives to coordinate the inspection details. Then, certified technicians performed an opening survey with a visual inspection and functional tests. After the survey, DH Pace provided a deficiency summary outlining high-level details of the visual inspection and function tests.

Finally, DH Pace submitted a written inspection report of the facility’s openings with recommendations of how the facility could fulfill their legal obligation to maintain openings in compliance with the pertinent codes and standards. The written inspection report covers multiple code sources including the following list:

  • International Building Code (IBC)
  • International Fire Code (IFC)
  • NFPA 80 for the care and maintenance of fire doors and other opening protectives
  • NFPA 101 for life safety
  • NFPA 105 for installation, maintenance, and testing of smoke door assemblies and smoke dampers

Based on the results of the FireCheck® Program inspection, the medical center acted on DH Pace’s recommendations. They contracted with DH Pace to provide and install all the materials necessary to bring the facility to 100% compliance.

DH Pace provided the following products:

  • Approximately 8,000 feet of smoke seal
  • 85 Door kick plates in various sizes
  • Approximately 80 mortise door edges
  • 25 Continuous hinges
  • 100 Brush sweeps
  • 20 Fire bolt door hardware
  • 20 New closers

The team fully replaced ten openings and relabeled approximately 150 openings to be labeled in accordance with compliance.

In addition to the summary and written report, the FireCheck® Program includes an annual re-inspection for the following year to ensure continued code compliance.

All told, DH Pace updated nearly 500 openings across the medical center to be code complaint. With just a few weeks before the project was to be completed, representatives from The Joint Commission arrived to inspect the facility.

The inspection went so well, the medical facility stated that the inspection representatives said they had set the standard for any health care facility and that theirs was one of the best inspections they had ever done.

Global Manufacturer Addresses Loading Dock Safety Concerns

Category: Loading Dock Equipment
Products: Truck Restraints
Industry: Manufacturing
Application: Loading Dock Safety


A global parts manufacturer for the lawn and garden and agricultural markets needed to make capital improvements to address OSHA and safety concerns at their loading docks.


The manufacturer contacted DH Pace to inquire about budgeting for truck restraints at their 56 existing dock openings. The customer was concerned about the safety and liability in loading and unloading materials at their docks. To ensure a safe material handling operation, they wanted an effective and dependable truck restraining system that was approved by the Occupational Safety and Health Administration (OSHA).

DH Pace recommended an automatic truck restraint designed to automatically position itself and secure a trailer’s rear impact guard (RIG). It reduces the likelihood of premature trailer separation during the loading or unloading process. Also, this restraint system offered a lighted communication system inside and outside the dock. The parts manufacturer submitted DH Pace’s quote for capital funding for the following fiscal year and won the project. The Company installed the truck restraints in the summer.

In the fall, the customer contacted DH Pace again. They had just begun to ship and receive materials locally in smaller box trucks with lift gates which were not compatible with the automatic restraints they had installed at their dock positions.



With a new goal in mind, DH Pace worked with the customer to evaluate their options. The Company recommended to install two automatic surface-mounted wheel restraints at two of the loading dock positions. These restraints are compatible with pup and lift gate trailers. Also, they offered safety features like automatic wheel sensors, LED interior and exterior communication lights and an exterior audible alarm.

Since two of the originally installed truck restraints had not been used, DH Pace returned the restraints for credit and worked with the truck restraint manufacturer to transfer the warranty.



In any building project, it is ideal to identify all the potential uses a space may need to accommodate upfront. Since a facility’s needs may change over time, that is not always possible to do. Therefore, DH Pace helped the parts manufacturer reassess their requirements and offered a solution that met OSHA’s requirements, upheld their safety goals and interfered the least with business operations and the customer’s recent dock investment.

Customer Comments

Pharmaceutical Manufacturer Implements New Clean Rooms

Category: Automatic Doors
Products: Clean Room Automatic Sliding Doors
Industry: Manufacturing
Application: Clean Room Environment


A laboratory supplying compounded medications expanded operations and needed 42 clean room automatic sliding doors.


The interior of the building for the growing lab had to be gutted and redeveloped as a clean room environment. In addition, the specifications called for hands-free operation for the sake of convenience as well as moving fragile contents between rooms.

The lab also needed the doors to be programmed in a specific sequence where one door opened and then closed before opening the next doorway. Configuring the door operations in this manner was a vital requirement to optimize the integrity of the clean room.


DH Pace provided and installed the 42 clean room doors with access devices operated by hand wave to open functionality for hands-free use. The wave plates allowed employees to pass through doors without physically touching them. To further support the clean room requirements, the Company recommended to install the door operators facing the exterior of the opening, as opposed to the interior, to mitigate any potential contamination.

The Company also provided approved wiring specifically for clean room applications. Both the clean room doors and the wiring met International Standards Organization (ISO) standards for operational requirements.

Overcoming Tight Installation Space for a Combination Rolling Steel Door

Category: Commercial Overhead Doors
Products: Rolling Steel Door, Solid Curtain, Perforated Curtain, Full Flush Steel Entry Door and Frame
Industry: Manufacturing
Application: New Opening for a Building Expansion


A global food products manufacturer added on to an industrial building and needed a commercial overhead door that allowed ventilation.


The food manufacturer added on to an existing industrial air compressor building. Their facility was undergoing upgrades to larger compressors and needed the extra space to accommodate the larger units.

The addition called for a new opening for a commercial overhead door. Because the facility manufactured food, the overhead door needed to be secure against potential contaminants like birds and rodents. It also needed to be able to withstand the high negative air pressure created by the constant operation of the building’s large air compressors. Because most bird and rodent screens are mesh, they were not a good option for this high-pressure environment. The manufacturer needed a deterrent solution that could withstand the pressure created by the compressors and not be sucked out of the door guides.

The big hurdle to overcome would be installing a commercial door that met these requirements and still fit within a snug 42 inches of back room space. That was the distance from the wall to an obstruction. Because of space considerations around the building, the customer was insistent on adding exactly the amount of space required to fit the components.


DH Pace installed a combination rolling steel service door in the building’s addition. The door design was configured to provide two different curtains in one door assembly. The door featured a solid curtain for use during extreme weather, as well as offering a level of security. It also had a perforated curtain to allow for air ventilation and pest control.

The door’s opening was 12 feet tall and the barrel assemblies were 4 feet tall. Since the end plates were 20 inches deep, that left only 22 inches of space within which the installation technicians could install the door. To comply with the customer’s fall protection safety rules, technicians were required to use a scissor lift during installation. This further limited the space the technicians had to operate within.

Traditionally, a project of this type would call for a duct lift or fork lift to bring the components into position. The luxury of space to do so was not available. Instead, the installers hoisted the door materials with manual
ratchet lever hoists attached to the building’s structural components and completed the installation.

To manage the flow of foot traffic, DH Pace also installed a full flush steel entry door and frame next to the rolling steel service door.

Airport Expansion Calls for Sliding Doors with Limited Sound Transmission

Category: Automatic Doors
Products: Revolving Doors, Sliding Doors, Walk-Off Mats
Industry: Transportation
Application: New Construction Project with Sound Transmission Class (STC) Requirements


An airport added new amenities and transportation options for over 54 million travelers that annually pass through its facility.


The airport partnered with a general contractor for a design-build project that expanded the airport, created new amenities including
a new hotel and connected the two by light rail transportation.

Because of the sensitive nature of the project, the airport requested all partners adhere to a non-disclosure agreement to keep project details confidential before the project became public knowledge. The project’s design called for minimal door frames by using all glass sliding doors.

The project also had to meet Sound Transmission Class (STC) requirements to reduce sound vibration. The problem was that the glass sliding doors originally specified for the project did not meet STC criteria. They lacked interlocking frames.

Additionally, the plans called for walk-off mats to be installed under the entryway revolving doors of the hotel’s main entrance to help control dirt, debris and moisture accumulation. Typically, revolving doors sit on a finished floor. In this application, the revolving doors needed to accommodate removing the mats for periodic cleaning. The mats trap debris and water below the surface and needed regular attention. The walk-off mats were also a safety feature. They help minimize the risk of slip, trip and fall accidents. Therefore, it was imperative to find a solution that worked with the revolving doors.


The DH Pace project team recommended using a proprietary fine-frame automatic sliding door with interlocking frames. The recommendation greatly improved the STC performance. This was an ideal door option in that it provided a very similar aesthetic to an all-glass, full-view door with minimal frame lines. In addition, this option created a better weather seal and the laminated glass glazing offered a better STC performance.

The customer approved the recommendation and the Company installed a total of 17 all-glass sliding doors. The doors were installed between the airport terminal and its new amenities, in an elevator lobby and in a train hall for light rail transportation.

In addition to the 17 sliding doors, DH Pace also provided and installed two automated revolving doors at the hotel’s main entrance. The team coordinated extensively between the general contractor, architect and mat manufacturer to devise an installation plan for the doors and walk-off mats. The installation plan called for elevating the revolving doors by two inches to allow for the installation and maintenance of the walk-off mats. Ultimately, all the materials were installed and seamlessly integrated together.

A close partnership between DH Pace, the architect, contractor and owner was critical in realizing the aesthetic vision for the design while still providing safe and secure doors systems for the project. Although requirements call for exacting precision, getting the right visual appeal is equally vital.

New Key Security System for Large School District

Category: Key Services
Product: Core Locksets, Keys
Industry: Education
Application: Rekeying Doors


One of the oldest and largest school districts tackled rekeying 28 school locations in one summer.


The district has over 100 school, administrative and support buildings which serve approximately 96,000 students in their system. They recognized their key systems were outdated, which could represent a security threat. The longer a key system is in use, the greater the chances are of losing control of the system.

The district planned a phased approach to rekey all schools. Phase one included 28 different schools and called for core replacements in nearly 4,000 openings.


The school district was familiar with DH Pace’s Key Services division. They had provided service in maintaining the school’s existing key systems. To be the least disruptive to normal school activities, DH Pace recommended to complete the work for the first phase over the summer months. This allowed for the school system to plan the repairs in a cost-efficient manner. If they had scheduled the work to be completed during the school year, they would have incurred additional costs to work outside of normal hours or on weekends.

Over the course of two months, the DH Pace team produced the pinned core, cut corresponding keys and then dispatched technicians to remove the existing cylinders and install the new system. During this time, approximately 4,000 openings were updated among the schools in phase one.

DH Pace turned over the used cores back to the school district. In the spirit of sustainability, the district keeps them on hand and reuses them in certain situations, like needing a door rekeyed in an emergency, turning a property over to another organization or installing in a new building they have purchased or taken over.

The school district’s first phase was completed on time and within budget. Completing the work across the thousands of openings in numerous school buildings went so well that the district is planning the second phase of the project with DH Pace to address the next set of buildings to rekey. The school district plans to continue working with DH Pace to rekey the rest of the district over the next few years.

New Power Plant Building Needed Massive Opening Quickly

Category: Commercial Overhead Doors
Products: Rolling Steel Commercial Overhead Door and Operator
Industry: Manufacturing
Application: Nuclear Power Plant


A power plant serving 1.2 million customers needed a massive door to help house new equipment.


The power plant was bringing in new equipment related to refueling the reactor. They needed an opening to be 40 feet wide and 30 feet tall to accommodate the machinery.

The power plant needed the door to secure the building. Unfortunately, they had a tight time frame. And, they weren’t having success finding someone to engineer it. Also, they needed the door to be installed in only two weeks.


DH Pace sourced an option for a rolling steel door and an operator. The heavy-duty overhead door was exactly what the power plant needed to enclose the industrial building. Due to the sensitive nature of the operations, the power plant required that the installation technicians attend four days of training. Also, they required the technicians to submit to background checks.

First, DH Pace engineered the door and issued the shop drawings. Then, they had the door manufactured to meet the customer’s requirements.

The components shipped directly to the job site. Once there, it was rigorously inspected to be allowed into the protected area. After the training, the four-person installation team had the massive door and operator installed in three days.



The project went off without a hitch. Ultimately, it ended up being one of the largest installations for the Company. The door and operator were produced and installed in only two weeks’ time. Afterward, the new refueling technology was secured appropriately.
