Box 746 Salina, KS 67402-0746 Ref: Oakdale Bridge NW of Bicentennial Building Dear Mr. Hoff: Thank you for giving us this opportunity to propose and provide our suggestions concerning rehabilitation of the existing bridge at the location referenced above. We look forward to serving the citizens of Salina. (A) INSPECTION: Our cursory inspection of the existing structure indicates the following: 1. There is some leakage of water through the concrete deck. It appears that this deck does not need to be entirely replaced, although surface deck repairs are needed at this time. The last inspection on June 26, 1987 shows a Suffi- ciency Rating of 99. We suggest a more thorough inspection by chain -dragging and 3/4 inch chloride sampling in order to make application for Federal participation. The chain -dragging will indicate the total extent of deck delaminations to date, plus those expected in the next few years. Chloride concentrations in excess of two pounds per cubic yard of concrete indicate a future rapid deteriora- tion of the deck. This will determine the salvage value and whether to replace the total deck. If the deck inspection results in a structure sufficiency rating of 50 to 80, the structure is illegible for Federal Bridge Rehabilitation Funds; if the structure sufficiency rating is less than 50, the structure is eligible for Federal Bridge Replacement Funds.

There is erosion at the abutment berms due mainly to the failure of a storm outlet structure (headwall). This can be corrected with proper backfill compaction, and erosion control. (B) INSPECTION PROPOSAL: ------------------- We propose to inspect the existing structure in accordance with and report the results to the Rural and Urban Highway Department. Fees for these engineering services shall be: 1) Basic Structural Inventory and Appraisal $300 2) Chain -drag deck and prepare drawing showing delaminated areas (City to provide Traffic Control) 2,700 3) Drill for ten (two in each span) 3/4" dia. chloride samples and report test results (City to provide Traffic Control, hammer drill, & one laborer 1,200 Inspection Fee $ 4,200 (C) BRIDGE STUDY DESIGN ALTERNATIVES: -------------------------------- Rehabilitation of the bridge (a) or Replacement of the bridge (b) will depend on the test results obtained during inspection. We propose to study the inspection results, prepare cost estimates and comparisons and obtain a new Sufficiency Rating from the Kansas Depart- ment of Transportation, Department of Rural and Urban Highways. We will also then make recommendations to the City. Fee for performing Study $ 400 TOTAL (B) + (C) $ 4,600 (D) FINAL PROJECT DESIGN: We propose to negotiate with the City and enter into a contract (an agreement) for the necessary engineering design plans as desired by the City and agreed to by both parties. We envision these future costs not to exceed $10,000. - 2 - In conclusion, Mid -Continent Engineers has the experi- ence and qualifications to provide the City of Salina this needed bridge expertise. If you need other information or desire a different approach to this project, please advise. We are available to commence work immediately. AGREED: MAYOR � Stephen C.
