David Dupree..is the "SFP" Design Manager. He is a superb designer with great attention to detail. He oversees and manages our designers schedules and makes sure the projects are submitted in a professional and timely fashion. Dave is also a design himself and one of the best in the business. He has worked in almost every area of the fire protection industry which gives him a wide knowledge base to pull from. Dave never sees a problem, only an oppurtunity with an easy solution.

John A. Denhardt, P.E. (FSFPE)..is the "SFP" Quality Control Manager and a qualified one at that. John holds a NICET Level III certification and a Fire Protection Engineering Degree, and has over 20 years of experience in the fire protection industry. Our designers are continually educated in the ever changing field of the fire protection industry. He oversees all drawings and calculations outgoing to make sure the necessary steps are addressed and taken.


We are capable of creating detailed gnatt chart schedules and numerous colored phase drawings for better project management.This is especially helpful when working in occupied buildings which stay in operation during construction hours. We are experienced in working with difficult logistical conditions (i.e. remote project locations, extreme weather conditions, top secret/high level security projects, high end finishes and accelerated schedules, above and around sensitive equipment such as computers or servers, irreplaceable collections such as historical books, records and artifacts) and are excited to do so.


Our engineering staff utilizes Computer Aided Design (CAD) for all our new or retrofit projects. We are capable of Building Information Modeling (BIM) and coordination with building elements and other trade disciplines. We specialize in retrofit installations while also performing all of our own hydraulic calculations in‐house. Where necessary we can perform a water flow test and/or detailed analysis on the water supply that supplies your system. We are more than capable of sizing and selecting fire pumps, underground water supplies, risers and bulk piping. Our designers are NICET (National Institute for the Certification in Engineering Technologies) Certified Designers (www.nicet.org).

Building Information Modeling (BIM)

Strickland Fire Protection uses a software package that conforms with the definition of BIM. Typical CAD software is vector based in that it does not recognize any group of vectors as anything other than that.  In other words if a designer draws a door in the CAD program it does not recognize the lines as a door. This is defined as "unintelligent." In an "intelligent" software instead of recognizing just the vectors, the program actually recognizes the lines as a door if stored in the database as such.  All designers at Strickland Fire Protection exclusively use this software package. The software is highly compatible however and CAD files can easily be integrated as well as exported. 

What is BIM?

     "A digital representation of physical and functional characteristics of a facility that has shared knowledge resource for information about a facility forming a reliable basis for decisions during it's life-cycle; defined as existing from earliest conception to demolition. A basic premise of BIM is collaboration by different stakeholders at different phases of the life-cycle of a facility to insert, extract, update, or modify information in the BIM to support and reflect the roles of that stakeholder."
