Fire Protection

Design is the deliberate act of considering the building, requirements and limitations at hand to produce the systems needed for safe, code-compliant and cost-effective operation. Antinomy recognizes that well-designed solutions require all these in addition to close coordination with design team and building ownership.

From simple horn & strobe fire alarm systems to complicated multi-zone voice evacuation systems, Antinomy is capable of designing your emergency evacuation solution. Fire alarm systems are often neglected during the building design process, despite the fact that they interface with major utilities in the building (HVAC, elevators, security, lighting, etc.) Antinomy views fire alarm as a key component of life safety and therefore designs for code compliant coverage and reliability. Due to the many interfaces involved, it is important for your fire protection engineer to have a holistic understanding of how the myriad other utilities should react to a fire event and control them accordingly.

Many combustible and non-combustible buildings require fire sprinkler systems to be installed to control the growth and spread of fire. Typically, buildings of four stories or more in height will also be required to provide a standpipe system as a source of water for the fire department to use with their hoses. Antinomy can design new, replacement and upgraded systems, as well as provide design documents for head relocation for interior buildouts.

We are thoroughly versed in Autodesk Revit and the building information modeling paradigm to provide coordinated, accurate and three-dimensional representations of building systems to work with your design team. Alternatively, we can perform in Autodesk AutoCAD (DWG and DXF formats) for projects designed in that space.

Building design is a complicated process with innumerable points capable of introducing error. Antinomy can review design drawings for new & existing buildings to assess code compliance and design appropriateness. As state-licensed fire protection engineers, Antinomy is also able to review documents for federal government projects.

Smoke Control & Rational Analysis

No system is as demanding upon the building or designer as smoke control systems. We have the experience to construct a solid foundation, specify interconnections and verify that operation is correct.

Antinomy uses state-of-the art computational fluid dynamics modeling techniques complying with NFPA 92 to design atrium smoke control systems. This methodology sets the standard for accurate results and generates clear, visual output to demonstrate the efficacy of the system design over the course of the fire scenario. This technique also permits us to gauge the impact of various architectural or mechanical system design choices on the smoke performance of the atrium. With modern building codes relying upon the fire protection engineer’s rational analysis to prove the value of the design concept to the authority having jurisdiction (AHJ), this visual proof has gained importance in the permit approval process.

Newly-constructed high rise buildings today require a means of protecting exit stairs to provide a safe path of egress to the grade level. Some of these buildings also require pressurized elevator hoistways. Antinomy’s network modeling approach constructs a digital model of the whole building to capture the effects of floorplan, elevation (height), weather and the competition between stair & elevator pressurization systems within the building to produce reliable and operational stair & elevator pressurization system designs.

Many themed amusement attractions and theatrical seating arrangements require removal of smoke from the show areas. Antinomy applies cutting edge fire modeling techniques and deep understanding of codes to provide the right solution depending upon occupant load, egress time and characteristics of the show. Our specialty is effective systems that approach invisibility, blending into the background to not detract from the performance or theming.

New smoke control & stair pressurization systems require initial testing or commissioning prior to being placed into service or the building receiving a certificate of occupancy. Older buildings may not have had this step performed, or may have had significant renovation since then and need a comprehensive test of smoke control, fire alarm and mechanical systems to ensure they are operating properly. Antinomy performs these tasks as well as regularly-scheduled annual and semi-annual testing required by code.

Code & Review

Codes and standards are in a state of perpetual motion. Whether you are designing within your ordinary framework or pushing your boundaries, we can help keep your project safe and compliant.

Codes are complex and are only increasing in complexity. We routinely consult on the Florida Building Code, Florida Fire Prevention Code, International Building Code (IBC), EPCOT codes (local to central Florida), NFPA codes & standards, and local codes & ordinances.

High Rise buildings, which typically are those of seven stories in height or greater, present several fire protection and code challenges. Choices such as construction type, structural fireproofing, exiting strategy and protection of elevator hoistways have substantial impact on safety, cost and floor plan leasable area. Let Antinomy’s experience work for you.

Most building codes in the United States require submission of egress plans for building permits. These plans depict the distribution of people within the structure and indicate how they exit from the structure and into the public way. Typically, these plans will also show various types of fire-rated separations, such as those between occupancies or for rooms of special hazard. A clear presentation of this material and early development promotes life safety and reduces the likelihood of redesign for exit purposes.

Building and Fire codes express a minimum acceptable level of safety in the built environment, but they do so indirectly with prescriptive requirements. Occasionally, these requirements can be infeasible or impractical and other solutions should be sought to achieve that level of safety. Antinomy’s deep understanding of code and experience in the field helps us to propose an equivalent method and provide analytical support to justify this course for approval.

Speciality & Performance-Based

Codes are written for general application to all building types, but this broad reach can result in design inefficencies. In these cases, a little analysis can go a long way towards reducing expense or improving performance.

Antinomy has extensive fire modeling capabilities that enable us to predict the result of fire on spaces and structural elements within them. This allows us to perform advanced “hourly” fire resistance rating calculations for steel, concrete and composite members as well as wall, floor/ceiling and roof/ceiling systems.

Smoke detection technology is evolving and takes several forms: photoelectric spot detectors, air-sampling pipe networks, video cameras, projected-beam detectors and new multi-beam detectors are increasingly common. The choice of detector used depends on the characteristics of your space, fuels present and the sometimes the need to conceal the system from view or provide access to for maintenance. Antinomy has experience in high-end and conventional smoke detection techniques.

Model building codes require that many warehouses and industrial buildings be fitted with smoke & heat vents to relieve combustion products, or be provided with exhaust fans in a regular pattern. Your insurer may prohibit either method. Antinomy has modeling techniques to align venting performance requirements with the hazard actually present in the building, rather than the one-size-fits-all approach of the codes.

Buildings with smoke control systems generally require a control panel that allows firefighters to alter the operation of the system. Such panels are to be used in emergency situations and need to be designed with care and simplicity in mind. We can provide a design for existing and new smoke control systems as well as review the work of other designers for correctness and conformance to best practices.
