SCOPE
ALL BIDS REJECTED: The proposed repairs include drilling and installation of (20) grouted tie-backs into the earth using pre-stressing strands which are anchored into a new cast-in-place concrete beam installed on the face of the seawall. The new beam will run continuous for 196 feet on the exterior of the seawall near the mean high tide line. The work will be performed in dry conditions, but the formwork and beam will be submerged by high tides during the construction period. Drilling debris and any excess grout will be entrapped at each work station for disposal. After the wale has cured the anchors will be pull-tested and if acceptable the anchor pockets grouted. Water turbidity will be controlled by a containment boom and silt curtain around the active work area. Work includes removal, temporary storage and installation or replacement of construction interferences including private improvements (docks, gangways, guide pile and decks) within the prescribed work area. Removed concrete guide piles intended for re-installation shall be identified by property location and then either; stored on a materials barge, removed from the jobsite and stored offsite in a Contractor controlled yard, or cleaned of marine growth within 24hrs of removal to control the smell and stored onsite within the 12 property work area in a stable manner which does not pose an adverse structural load, public safety or navigation risk.
