On plan sheet C420 there is a callout for an air and vacuum valve assembly on the 24"steel Air Vac Assembly to be 1-inch outlet line of the West Reservoir.Note 6 calls for the assembly to be per City of Everett detail 512.This detail is for a 1 inch air/vac assembly.This detail says any air/vac assembly of another HD Fowler size shall be designed and approved by the City.Please provide a size and design for this assembly if it is In fact larger than 1 Inch. I'd like to submit our F1 Restrained Expansion Joint for this bid.It meets all of the specifications Expansion joints to be per specification. laid out in the project document,except for the expansion requirement.The specification says that for 12"nominal sizes they require 8"of expansion,and for greater than 12"they require 16"of expansion. Just a couple of thoughts on this requirement.In my experience,sometimes the specifications Romac are written for extreme scenarios and the project may not require that much linear expansion. The other scenario I've run across is that in some cases it is the offset which is actually the most critical,not Just the linear expansion,and we can make the F1 to accommodate 4"to 20"offset. There are two hatch openings on each tank,a 12'x14 equipment hatch and a 4'x10'access hatch.The 4'x10'access hatch is located In detail 3 on drawing Ell we the hatch openings and it appears to be one on the North Tank next to the overflow pipe,requiring an overflow switch.Detail 3 on Ell shows the required electrical layout for each hatch. and one on the South Tank?Please let us know if there is one hatch opening on the south tank Dalton Electric and one on the north tank,or is there 2 hatches on the north tank and 2 on the south tank? In detail 1 on drawing E3 it only shows 1 conduit going up to 1 junction box on each of the tanks. Conduit shall be run from the 1-box to each hatch.Response to the above question shall clarify what equipment is at each hatch. Please show/identify the conduit going to the second hatch on each of the tanks if there are 2 Dalton Electric Contractor shall determine most efficient route in field. hatches on each tank?Please clarify?
