Fire Sprinkler
System Installation

New construction, a building never previously sprinklered, or a full system replacement. We design and install fire sprinkler systems to NFPA 13, sized to the actual occupancy and hazard, not a generic layout.

Direct Answer

Firemax Fire Protection designs and installs fire sprinkler systems for new construction, previously unsprinklered buildings, and full system replacements throughout South Florida. Every system is hydraulically calculated to NFPA 13 for the building’s actual occupancy hazard and water supply, permitted through the local AHJ, and commissioned with full flow testing before handoff.

What Goes Into a New Sprinkler Installation

A fire sprinkler system is not a standard kit applied to any building. NFPA 13 organizes buildings into hazard classifications, light, ordinary, and extra hazard occupancies, each requiring different sprinkler density and spacing, and the correct design depends on accurately classifying the specific building and its use before a single pipe run is drawn. A warehouse storing palletized goods needs meaningfully different protection than an office building or a light manufacturing space, even at similar square footage.

Water supply is the other half of the equation, and it is the part most often assumed rather than verified. A system’s design has to be matched to what the site’s actual water supply, whether municipal or a dedicated fire pump, can deliver under demand. A design that looks correct on paper can fail in practice if the available flow and pressure do not support it, which is why we verify supply directly rather than relying on general assumptions about municipal capacity.

We manage the complete installation project: hazard classification, hydraulic design, plan submission and AHJ permitting, physical installation, and commissioning with flow testing, so a general contractor or building owner has one point of accountability for the fire sprinkler scope rather than coordinating design, permitting, and installation across separate parties.

The Standard

The building’s hazard classification determines the design. Getting that wrong undermines everything that follows.

NFPA 13 defines light, ordinary, and extra hazard occupancy classifications, each requiring different sprinkler density and spacing.

What Our Installation Service Covers

Hazard Classification and System Design

We classify the building’s occupancy hazard under NFPA 13 and design sprinkler type, spacing, and density accordingly, whether the project calls for a wet pipe, dry pipe, pre-action, or deluge system.

Water Supply Verification

We verify actual site water supply against the hydraulic demand the design requires, identifying early whether a fire pump or other supply enhancement is needed.

Hydraulic Calculation

We hydraulically calculate the system to confirm actual delivered density and pressure at the most demanding point, not a general estimate.

Plan Review and Permitting

We prepare and submit the design package to the local AHJ, respond to plan review comments, and coordinate final inspection.

Physical Installation

We install piping, sprinkler heads, control valves, and monitoring devices per the approved design, coordinating with other trades on the construction timeline.

Commissioning and Flow Testing

We flow test and commission the completed system, verifying actual performance against the hydraulic design before issuing final documentation.

Planning new construction or a full sprinkler system replacement? We handle hazard classification, design, permitting, and installation as one coordinated project.

Common Installation Mistakes We Correct

01

Hazard Classification Based on Building Type, Not Actual Use

A warehouse classified generically without accounting for what is actually stored, or a mixed-use building treated uniformly across genuinely different occupancies, can end up under-protected in the areas that carry the highest actual hazard.

02

Water Supply Assumed Rather Than Verified

Designs based on general municipal supply data rather than a site-specific flow test can look correct on paper while falling short of actual deliverable pressure and flow, especially in older infrastructure areas.

03

System Type Selected for Cost Rather Than Suitability

A wet pipe system installed in a space subject to freezing risk, or a dry pipe system used where a simpler wet system would suffice, both represent a mismatch between system type and actual site conditions.

04

Coordination Gaps With Other Construction Trades

Sprinkler installation that is not properly sequenced with ceiling, mechanical, and electrical trades can result in costly rework when conflicts surface late in construction.

05

Commissioning Skipped or Abbreviated

A system installed correctly on paper still needs actual flow testing to confirm real-world performance, and skipping or rushing this step leaves genuine questions about system performance unanswered.

A design that looks correct on paper still needs a verified water supply behind it.

We test actual site supply before finalizing any design, avoiding the costly discovery of a supply shortfall after installation is complete.

Our Design and Installation Process

1

Site Survey and Hazard Classification

We survey the building, classify its occupancy hazard under NFPA 13, and document existing conditions relevant to the design.

2

Water Supply Testing

We conduct or obtain a current flow test of the site’s water supply to confirm actual available flow and pressure.

3

Hydraulic Design and Permitting

We hydraulically calculate the system, prepare the design package, and submit it to the local AHJ for plan review and permit approval.

4

Installation and Trade Coordination

We install the system, coordinating with general contractor and other trades on sequencing and access.

5

Commissioning and Final Inspection

We flow test the completed system, correct any deficiencies, and coordinate the final AHJ inspection and system acceptance.

Why Hydraulic Calculation Beats a Standard Layout

It is possible to lay out sprinkler heads on a grid that looks reasonable without ever calculating whether the system actually delivers the required density where it matters most.

Density requirements vary by hazard, and so does the hydraulically remote area. NFPA 13 does not just specify how far apart sprinkler heads can be. It requires calculating actual water delivery at the hydraulically most demanding point in the system, accounting for pipe friction loss and elevation across the full route from the water supply. A layout that spaces heads correctly can still fail to deliver adequate density at that remote point if the piping was not sized and calculated to support it.

Water supply is the constraint that design has to work within, not around. A hydraulic calculation is only meaningful if it is checked against what the site’s actual water supply can deliver under demand. This is why we test supply directly rather than relying on general municipal data, since supply capacity varies meaningfully by location and can be lower than general assumptions suggest, particularly in areas with older infrastructure.

Commissioning is where the calculation meets reality. A hydraulic calculation predicts system performance; flow testing during commissioning confirms it. Skipping this step means trusting the paper calculation without verification, and we treat commissioning as a required step for every installation, not an optional final check.

Applicable Codes and Standards

Every system we design and install is engineered and documented against the specific standards governing fire sprinkler systems.

Frequently Asked Questions: Fire Sprinkler System Installation

Timeline depends heavily on building size and complexity, with design and permitting typically taking longer than physical installation. We provide a specific project timeline after the initial site survey and hazard classification.

This depends entirely on whether your site’s available water supply meets the hydraulic demand the design requires. We verify this through direct flow testing rather than assuming based on building type or size.

Each system type suits different conditions: wet pipe for standard heated spaces, dry pipe for areas subject to freezing, pre-action for spaces where accidental discharge is a particular concern, and deluge for high-hazard applications requiring simultaneous discharge from all heads. We recommend the type matched to your specific building conditions.

Yes. We prepare and submit the full design package to the local AHJ, respond to plan review comments, and coordinate the final inspection as part of the installation project.

Yes. Retrofitting a previously unsprinklered building is a common project type, and we design around the building’s existing structure and any access constraints that come with retrofit work.
