FIRE PROTECTION SURVEY ASSISTANCE

Study phases

  Fire study steps.

Preliminary Design Phase :

During the Preliminary Design phases (APS – Preliminary Project Design and APD – Final Project Design), Nenyo conducts the essential technical and regulatory analyses required to define an efficient fire protection system compliant with current standards.

These studies include the development of initial plans, sections, functional sketches, as well as preliminary theoretical calculations to size sprinkler systems or other fire safety devices. They allow us to propose a solution that precisely meets the project’s needs while integrating applicable regulatory requirements (APSAD rules, NFPA, EN standards, etc.).

At this stage, the project remains flexible: close collaboration with the Project Owner is essential to validate technical assumptions, operational constraints, and economic objectives. This phase also includes consultation and communication with relevant administrative authorities and organizations (fire departments, insurers, environmental agencies, water utilities) to ensure the feasibility and future compliance of the installation.

Design Phase :

The PRO phase aims to consolidate and formalize all the technical, economic, and regulatory assumptions retained for the project, in preparation for the tendering of the construction works. It results in a complete dossier including detailed execution plans, hydraulic and technical calculations, as well as all written documents (specifications, cost estimates, schedules) necessary to precisely define the project’s objectives, stages, and resources.

In the field of fire protection, this phase is crucial to ensure that sprinkler installations or fire safety systems comply with regulatory requirements (APSAD, NFPA, EN standards, etc.) and the specific constraints of the site. It also allows for the validation of technical assumptions and obtaining administrative approvals from relevant authorities (government, insurers, fire departments, environmental agencies, water utilities, etc.), thus securing the project’s launch and execution.

Execution Phase :

The execution study is a decisive step in bringing a fire protection project to fruition. Its objective is to detail, size, and schedule all necessary interventions to ensure completion in accordance with client expectations, current regulations, and quality standards. This thorough technical phase helps minimize uncertainties, secure deadlines, and ensure perfect coordination of on-site work. By anticipating every aspect of the project—equipment selection, network layouts, detailed hydraulic calculations, and integration with structures—it significantly reduces the risks of errors or cost overruns.

Depending on the nature and complexity of the project, Nenyo may carry out these execution studies directly (partially or fully) or delegate their completion to the awarded contractors. In the latter case, we provide strict oversight through the VISA procedure, issuing approvals after reviewing plans and technical notes to certify that the selected solutions comply with project specifications and are compatible with all planned installations.

  Our tools.

   AutoCAD.

AutoCAD is a computer-aided design (CAD) software widely used in the field of fire protection to produce technical 2D drawings. It enables precise design of installations such as sprinkler networks, dry risers, fire hose reels, and fire detection systems. Thanks to its powerful tools, AutoCAD facilitates the creation, modification, and sharing of plans that are essential for ensuring the compliance and performance of fire safety systems.

  Revit.

Revit is a computer-aided design software dedicated to the building industry, renowned for its power as a BIM (Building Information Modeling) tool. It enables the creation of intelligent 3D digital models that incorporate all the technical data required for the design, coordination, and management of fire protection projects. By centralizing information, it facilitates collaboration among all stakeholders and optimizes future maintenance.

   SprinkCALC.

SprinkCALC is a hydraulic calculation software specialized for sprinkler systems and fire protection installations. Developed by SprinkCAD (part of the Tyco/JCI group), it automates and secures complex network sizing calculations in compliance with major international standards (NFPA, EN, FM, etc.). This software streamlines the design process by providing precise analysis of pressure losses, flow rates, pressures, and pipe sizing.

BIM, a valuable tool.

BIM (Building Information Modeling) is a collaborative method based on an “intelligent” 3D digital model that enables the sharing and management of all technical data throughout a construction project. It facilitates coordination among the various stakeholders, from design through to construction. Thanks to BIM, errors can be anticipated and corrected as early as the design phase, costs can be optimized, and precise execution plans can be prepared. These immersive tools also help to better understand potential hazards and define appropriate responses before any work begins on site.
