We welcome the opportunity to join development teams to solve building structural challenges. Our expertise in structural engineering focuses on site design, but our experience allows us to provide value added to support the design of structures, buildings, and infrastructure. From reinforcing an existing building/tunnel to designing foundations for sanitary sewer facilities, we are ready to develop and implement cost effective solutions for structural challenges. Whether your project involves a retrofit or new construction, demolition or expansion, failure analysis and damage repair or change of occupancy, we offer concrete engineering, structural steel engineering, building system engineering.

El Dorado Correctional Facility
Utility Tunnel Replacement

El Dorado, Kansas

This replacement project provided utility services to multiple locations throughout the correctional facility.  The utility tunnel system was designed for functionality, flexibility, and with consideration for maintenance issues.  Since the tunnel was within the confines of a correctional unit, security was a key issue.  Cook, Flatt & Strobel assisted an inmate labor crew in initiating the construction activities.  The project included:


» Over 4000 feet of utility tunnel

» Cross section up to 12’ x 9’

» Waterproofing including waterstop joints

» Complete drainage system

» Precast removable top

» Interface with existing building

» Utility support design

» Thrust restraints for pressure piping

» Water, electrical, steam, and condensate return         

    utility piping

» Security design and coordination
