IND$AN RIVE COUNTY DEPT. OF UTILITY SERVICES PR POSED ENGINEERING SCOPE AND BUDGET FOR WABASSO BRIDGES HANGING REUSE MAIN CROSSINGS INSPECTION, SURVEYING, AND REPORTING SERVICES November 17, 2015 PROJECT SCOPE, PARAGRAPHS A THROUGH H A. Inspection Scaffold - Design, bid and have new inspection scaffold manufactured specifically for newly constructed bridge railings. At the termination of this project, the Owner may, if desired, claim ownership of the newly manufactured scaffold upon execution of a release of liability. The scaffold may then be used for subsequent inspections on the Bridges. Design of the Scaffold is included as "Attachment No. 1". Quotes for the Scaffold and Scaffold Platforms are on Pages 12 and 13 of "Attachment No. 2". B. Survey Crew (3 man) - Using tape measure and temporary grease pencil , the crew shall layout stationing on each bridge wall for the 3,400 E linear feet. The crew shall also be used to transport and assist with the scaffold: installation; relocation; and removal. C. FDOT MOT Plans and Permitting - CAI shall prepare and obtain a FDOT, District 4, General Use Permit for the Field Inspection Work and the Maintenance of Traffic (MOT) Plans. D. Field Maintenance of Traffic - The CAI Inspection method anticipates no lane closures for the Survey or Inspection Services. All Inspection and Survey work, except surveying on the causeway bridge, shall be behind existing constructed barriers. CAI shall stagger the causeway surveying to limit exposure to less than 60 minutes at a time. These measures will reduce the signage requirements and project costs. Temporary MOT signage shall be provided, installed and removed each day while personnel and equipment are on the Bridges. E. Pipeline Inspection - The entire existing exposed length of both 12 -inch diameter Reuse Main pipes (approximately 3,400 linear feet each) shall be visually inspected, with pictures and notes taken of abnormal exterior wear and/or significant lengths of routine excessive wear. Pictures shall be related to the surveyed stationing. Additional inspection using ball -peen hammer for soundness and electronic coating thickness tester shall be utilized. In addition, the inspection shall include the tapping of each Main at two locations to produce "coupons" of the metal sidewall profile. Locations shall be coordinated with the Owner and taken as close to the top of pipe as can be conducted with the tapping equipment. We have made arrangements with Mr. Rick Sheltra of PRP Construction (license GC1510570) to supply the tapping materials and equipment needed to obtain the "coupons". A quote for, the Tapping Supplies and Services is on Page 14. F. Pre -Report Meeting — Upon engineering review of the field data, conducting alternatives analysis and preparing suggested conclusions, this material shall be presented to the Indian River County Department of Utility Services in raw data and calculations. CAIshall attend a review meeting •to discuss the raw data, calculations and conclusions with the Department representatives. Questions regarding any of these topics shall be discussed and if not resolved atthe meeting shall be clarified prior to Final Report production. Any new topics or analysis requested of the Engineer shall be considered additional services. Page 3 of 14 N:\SDS\15-541E (TRCUD Wabasso Causeway)\Proposal\Rev_Proposal.doc
