Construction Services and Part-time Construction Observation Services <br /> 11 , Project Close-Out Services <br /> These services are discussed in more detail below . <br /> B . Eneineering DesiEn Services and Surveying Services — Prepare detailed engineering <br /> design calculations and sketches as necessary to replace the existing spillover gate at each of <br /> the four existing radial arm water control structures , with an overshot gate . Base the designs <br /> on an overshoot gate manufactured by Armtec , Limited (contact Mr. Frank Stang of Armtec <br /> at 800-955 -9587) . Work closely with Armtec and provide all Structural Engineering services <br /> required for a complete installation of an Armtec overshoot gate and appurtenances , at each <br /> of the four locations . Such services shall include, but are not limited to structural slab <br /> thickeners ; a concrete upstream laminar flow channel ; pier extensions (if necessary) ; a <br /> downstream energy dissipation pool ; sill design ; vibration dampeners ; and gate base hinge <br /> plate and side- swipe plate connections . <br /> In conjunction with the engineering design services , provide surveying services as necessary <br /> to accurately draw and dimension each of the four existing radial arm water control <br /> structures . Prepare existing condition drawings for each of the four existing structures , with <br /> plan view, section views , and details . For each of the four structures , the existing condition <br /> drawings shall indicate existing structural components , dimensions , and location of the gate <br /> to be replaced. In addition to using this information for the structural engineering design, <br /> these drawings shall be included in the bid package for the use of bidders for their bid <br /> preparation. <br /> Establish Permanent Bench Marks (PBMs) at each of the four existing radial arm water <br /> control structures . The Contractor will use these PBMs during construction. Show PBMs on <br /> the Construction Drawings . <br /> Determine if the existing concrete structures at each of the four locations require "stiffening" <br /> in order to accommodate the new overshoot gates . Working with a geotechnical engineering <br /> firm selected by the COUNTY, determine the types of tests , quantity, and test locations <br /> necessary to provide the information required to make these decisions , and coordinate said <br /> testing with the geotechnical firm. Based on this information, for each structure, recommend <br /> whether or not additional stiffening is required . Because it will not be known if such <br /> stiffening is required until said testing is complete, any Structural Engineering design <br /> services required to "stiffen" the structures based upon said test results are not included in <br /> this Scope, and shall be considered an additional service. It is estimated that additional <br /> Structural Engineering design services , if necessary, will be in the range of $ 3 , 000 to $ 5 , 000 <br /> F:\Public Works\KeithM\stormwater ProjectsTast IRC\Contracts\Consultant Contract with Carter & Associates\Werk Order No. 2 - Replacement <br /> of Radial Arm Gates\Work Order No. 2 - Latest Revision .doc 2 <br /> EAST INDIAN RIVER COUNTY MASTER STORMWATER MANAGEMENT PLAN <br />
