CITY OF GERMANTOWN ADDENDUM NO.5

COG2022-04 ELEVATED WATER TANK

The attached items on the above-named Project will be updated and adjusted (if required) by this Addendum No. 5 so as to reflect the revision to the Request for Bids: Clarification: Funding: There is a good possibility some of this project will be funded with ARP money, the awarded contractor will be required to provide their DUNS number and be registered with SAM.gov Questions: The following questions have been submitted: Question: What level of containment is required for this project? Answer: Due to the proximity of the tank in relation to surrounding structures and roads, full containment with top cap will be required. The Contractor shall supply, install, operate and maintain a Class 3A shroud conforming to SSPC Guide 6. Question: Will there be a laydown area identified? Answer: A laydown area of approximately 150 feet by 100 feet will either be utilized on the City of Germantown property to the east of the site or on the adjacent subdivision property. The final location will be somewhat dependent on the state of development of the subdivision at the time the laydown area is needed. Question: Could the number of load tests required be verified? Answer: Based on the recommendation of the Geotechnical Engineer, if auger cast piles are utilized with a Factor of Safety of 3, then a static load test is not required.
