Port Gardner Storage Facility Volume 7 Attachment O <br /> Page 28 <br />CITY OF EVERETT ⋅ 3200 Cedar Street ⋅ Everett, WA 98201 ⋅ (425) 257-8800 ⋅ Fax (425) 257-8882 <br /> <br />150 ksi is acceptable. Project specifications are designed for lower strength bars. <br />If alternative grade is used, splice length, development length, embedment depth, <br />and steel fabrication and testing must comply with applicable ACI standards for <br />150 ksi steel. <br />Q144 - Please confirm mill secondary micropile casing can be used for micropile casing. <br />Confirmed that secondary micropile casing can be used for micropile casing. <br />Q145 - Please confirm Type 1L cement can be used to prepare micropile neat cement <br />grout due to local availability. <br />Confirmed. <br />Q146 - Standard detail for Manhole Pile Supports C82001P calls out 9-micropiles while <br />the table on Sheet S-00-0005 only lists 8-micropiles at CSMH-15-01 and CSMH-15-02 <br />each. <br />Refer to Drawing S-00-0005 for the number of piles to be installed at each <br />structure. The number of piles show in in Standard Detail C82001P is intended to <br />be diagrammatic. <br />Q147 - Please confirm only the 10-micropiles at the Combined Sewer Debris Removal <br />building will be installed indoors while all other micropiles will be installed outdoors with <br />no overhead structure restrictions. <br />The 10 piles specified for Area 25 will be installed under a new addition that is <br />being added to the existing structure, not inside the building. Additionally, four <br />piles will be installed within the Area 40 Diversion Structure, see Drawing S-40- <br />1003. This project selectively uses micropiles in lieu of the 18" steel piles due to <br />limited overhead clearance areas on the project site. For example, the close <br />proximity of CSVT 10-01 to overhead power lines. <br />Q148 - Dwg S-20-3010 Detail “F” calls out “NEW TYPE E FILL CONC”. Can you please <br />provide a specification for that concrete type? <br />See specification 03 30 00 Paragraph 2.02.A <br />Q149 - Dwg S-20-3002, Key Note 2 refers to Specification Section 33 05 13, however <br />section 2.24 of the referenced spec section makes no mention of this location in the <br />“Manhole Schedule”. Please clarify. <br />Keynote 2 references Section 33 05 15 as it describes frames and covers. Cover <br />in question shall be 36”, pressure rated and watertight and shall be as <br />manufactured by EJCO or approved equal (per COE STDs). <br />Q150 - Dwg S-20-1002 Roof Plan lacks details for connection of new roof slab to the <br />existing exterior walls. Please clarify if structural connection is required.
