EPC in fire extinguishing system installation; It is a turnkey project management and implementation method that covers Engineering, Procurement and Construction items. In EPC contracts, the contractor is responsible for the entire project management from design to procurement and then to the planning, logistics, assembly, testing and commissioning stages. It provides great advantages to the project owner in terms of project manageability, especially since it provides a holistic approach to comprehensive projects where different fire extinguishing systems are combined. One of the advantages of EPC contracts is that they allow the project owner to reduce risks without being too involved in project management. Another advantage of EPC contracts is that they generally provide faster project delivery since all project stages are completed by a single EPC contractor under a single contract. For this reason, many project owners prefer to make turnkey contracts with EPC contractors when working to carry out highly program-oriented and comprehensive projects. As part of the agreement for EPC contracts, the EPC contractor undertakes three important components of a project:

• Engineering and Design – Detailed engineering design and planning of the entire project is carried out.

• Procurement – The EPC contractor supplies all necessary materials and equipment to implement the design and undertakes the logistics.

• Construction – The contractor carries out the mechanical assembly and installation of the systems and delivers the systems to the project owner after testing and commissioning.

Especially in the installation of critical fire suppression systems, a harmonized workflow from pre-planning to installation, completed by a single team, allows EPC contractors to overlap project phases and optimize the project as a whole, while also providing controllability for the project owner in comprehensive projects.
