O'Neill II, CPPO, FNIGP ector of Purchasing and Risk Management SA 10/2004 2 Description for Concrete Box Culvert Sections The City of Fort Collins will be replacing approximately 280' of an existing underground irrigation culvert. In order to accomplish this, the City plans on using a set of precast concrete box culverts to replace a majority of this ditch. The dimensions of the precast sections are 2.5 feet tall (interior dimensions) by 9.0 feet wide (interior dimensions). The thickness of the walls of the precast sections should ideally be 9" but must be built to support an HS-25 loading standard. Epoxy coated steel should be used as the reinforcing agent. The City plans on transitioning the single culvert ditch into two culverts to reduce the height of the ditch given existing pavement constraints. Therefore, there will be twice as many precast sections needed. The total distance of precast sections needed is 480 lineal feet (2 x 240' - the actual distance the sections will cover). As can be seen from the attached drawings, the two boxes will sit side by side, separated by 1". The following table summarizes the precast sections needed: Interior Height 2.5' Interior Width 9.0' Wall Thickness Ideally 9" Lineal Foot 480' Loading Standards HS-25 Reinforcing Epoxy Coated Steel The end pieces of the precast sections will need to be constructed with a smooth face on one side of the section so that concrete tie-ins can be constructed. The boxes should be constructed with lifting holes for ease in placement during construction. Along with the boxes, shop drawings will need to be supplied. PROJECT SCHEDULE: The project will be built in two phases. The first phase of the project is scheduled to begin on January 3, 2005 and will require approximately 318 lineal feet of box culvert. The second phase of the project is scheduled to begin on March 1, 2005 and will require 162 lineal feet of box. There will be an opportunity to store box sections on site. With your bid, please specify the earliest you expect to beginning shipping sections of box. SPECIFICATIONS ATTACHED: 1. Arthur Ditch CBC at Mulberry St. Culvert Details: Sheet BC2 and 2.
