21 Cost Estimate Report Project Notes Page ii Date Author Note 12/5/2012 Losak LEVEL OF DESIGN: Pilot Feasibility Study. LEVEL OF COST ESTIMATE: Class 3. SYNOPSIS: The purpose of this project is to manage (reduce) the flood damages to structures in low lying areas along upper Wilson's Creek and Jordan Creek within the city limits of Springfield, Missouri. The work for this alternative includes channel excavation (earth and rock), bridge and culvert enlargement or replacement segmental block retaining walls, highway bridge pier reinforcement, and utility relocations interfering or blocking the flow area within the enlarged channels section within Reach E1 and construction of flood water detention basins in. Some sections of the channel are concrete lined with vertical side slopes. The work area land use for this alternative is to sparsely developed industrial areas in west central Springfield. Excavation quantities are thought to be well quantified since they were derived by the civil designer from over five hundred cross sections. These cross sections were first used for the hydrology and hydraulics studies.assumptions: 1. There will sufficient land easements for working room for trucks to drive through access so that the hydraulic excavators may continue to work at near optimum rate.2. All excavated material is required to be hauled off site for disposal. 3. Waste excavated material (earth and rock) is assumed to be disposed of within 10 miles of the worksite. The sponsor has stated that there are always contractors wanting fill material. 4. Hazardous, toxic, and radiological waste (HTRW) will be removed by the Springfield from the work area before construction begins. 5. The working room for construction of the Phelps Street reinforced concrete box culvert is too little to accommodate using pre-cast concrete boxes units so it was assumed that utilizing cast in place construction is required. X. See folder notes with in the cost estimate for additional notes.inclusions IN THE COST ESTIMATE:1. Job Office Overhead (JOOH) of 13.0 percent in the Class 4 estimates and calculated JOOH in the two (Plans F & G) final alternatives. 2. Home Office Overhead of 8.0 percent in all alternatives based upon common rates. 3. Profit of 9.38 percent derived from the weighted guidelines method. 4. Bond of 0.98 percent based upon the MII embedded bond table.
