• Temporary Shoring: if this is needed, there must be a submittal by the contractor for review. JA recommends that an access plan be submitted for review. • Soldier Pile Grout: I have no problem with the strength of the concrete or CDF, but there is NO discussion of time before excavation. Lean concrete takes time to achieve its strength and there should be a restriction on when the face of the piles can be excavated. • Shop Drawings: the designer refers to an ARCHITECT.... Is there an architect on this project, if so WHO? The real question is who is the project manager of this project and who is answerable if the plans are not being followed. Is it the owner and are they knowledgeable enough to control the contractor's operations. I think the City should require one person be designated at the project manager. • Lagging: the 2 inch clean crushed rock needs to be specified with a WSDOT material so everyone knows what is being used. Sheet 52.1 • More detail is needed on the Wall Plan that contours the backfill into the existing ground at both the north and south ends. Water coming around the ends must be controlled properly so erosion does not take place at the ends. A surface water runoff plan is needed. Sheet SM • The low permeability material must be specified by a WSDOT material. • The removal of material in the front must be designed as to the amount and a plan of how and where it is to be removed, General Comments • These are structural drawings and for that they are adequate if my comments above are incorporated; however, there are NO civil drawings concerning earthwork. The areas not discussed or described are: o the ends of the wall and how they are to be stabilized from erosion; o the adjacent and damaged properties below. Are these properties just being Icft as they are? • Where is the planting plan being presented? • Who is designing the stonnwater collection and piping? That is typically NOT left to the geotechnical engineering firm but done by a civil firm. • Repairing the hillside below the area where the wall is located is as critical as the top. They should be permitted at the same time and the wo ust be tied together and enforced by the City.
