Step 3- Final Documents and Assist with Bidding <br />A�er we have reviewed the report with the City we will: <br />� Prepare final design documentsincluding drawings and specifications for the Oval's chiller renovation <br />and refrigeration system improvements. Specificationswill include general project conditions, <br />construction contract, form of agreement between the City and the contractor, bid proposal <br />requirements and forms, and technical sections. The documents will include an alternate bid item for <br />replacing the existing chiller vessel with a new vessel. <br />Provide a final estimate of probable construction costs. <br />Provide recommendations on bidding and award schedule. <br />� Answer questions during the bidding phase of the project. <br />�e present at bid opening <br />Review bids submitted by the contractors <br />� Recommend award of contract. <br />Prepare construction contracts for review by the City. <br />Step 4 - Construction Services <br />We will pr�vide Construction Engineering Services as requested by the City. We will perform site <br />observations throughout the duration of the project. The number of inspections and involvement during <br />construction �i�l vary depending on the experience level of the selected contractor and condition of the <br />chiller vessel. <br />If the chiller vessel shell is found to be corroded we will assist the City in selecting a materials testing firm <br />to the level of corrosion and thickness of the steel wall. The cost of the material testing will be paid for by <br />the City. <br />We will also perform contract administrationtasks such as shop drawing review of all materials and <br />equipment, processing pay requests and change orders and will answer questions irom the contractor. <br />Step 5—�valuate the Option of a Plate and Frame Chiller Type System <br />If this option is selected the evaluation will be performed between Steps 2 and 3 listed above. <br />During this step we will: <br />■ Evaluate the feasibility of installing a plate and frame type chiller system in place of reconditioning the <br />existing shell and tube condenser type system. <br />Write a letter report including and discussing the following: <br />� A description of the plate and irame system that would best fit the existing refrigeration <br />system including space needs and code related issues. <br />f1 Discuss the feasibility of separating the single refrigeration system into two separate <br />systems to create redundancy in the system. <br />�� A comparison of the existing shell and tube chiller design to a plate and irame chiller <br />system including efficiency, capital costs, life expectancy, operational and maintenance <br />costs and any other advantages and disadvantages for each system. <br />Reviewthe findingswith the City. <br />If the City approves this type of system in place of renovating the existing shell and tube chiller system <br />we will provide the City with a revised design proposal to include this change. <br />�Ir.
