Services

Tetra Protection uses a specialized software, as an overlay program for AutoCAD® allowing a fully integrated fire sprinkler design along with pressure loss and sprinkler flow calculations.  The following services are offered to Engineering Firms and Contractors:

Quick Estimate

Preliminary hydraulic calculations will be provided to the Client to help determine whether a fire pump is required or assist a Contractor in bid proposals. Information required from Client include:

  • Type of system: Grid, Loop, Tree, or Standpipe

  • System type: Wet or Dry

  • Occupancy

  • Water supply information

  • Sprinkler requirement (sprinkler head spacing, branch spacing, riser height)

  • Pipe sizes and location

Hydraulic Calculations

Used by Clients that design the sprinkler layout but require assistance with hydraulic calculations

Complete hydraulic calculations will be provided to the Client along with marked drawings with hydraulic reference points and pipe sizes.  In addition to the information noted above (Hydraulic Estimating), Clients must provide the following:

  • CAD drawings showing systems layout with pipe location and sizes

  • We will calculate requirements based on the most remote area and provide suggestions to Client with regards to sprinkler system design: sprinkler spacing, branch/main feed pipe sizing, etc.

Fire Protection System Design

Used by Clients that would like the drawings, specifications and hydraulic calculations to be prepared by Tetra Protection. Note, Architectural and structural drawings must be provided for obstructions interference with sprinkler coverage.
