The objective of this requirement is to evaluate the effectiveness of a single layer armor system and compare its performance to the two-layer system required by the Department of State Armored Vehicle Specification. This effort will determine if there is opportunity to reduce the weight and overall armoring cost of DEAV AVs while maintaining equal protection from ballistic and blast threats by removing one of the specified armor layers.

ITB #22079 - Manho le Lining The City of Independence, Missouri (herein referred to the “City”) requests sealed bids from qualified firms to install a monolithic multi-layer/component manhole lining system to provide infiltration and corrosion protection. The protective lining system will be a multi-layer protective lining system consisting of a (1) polyurea adhesion coating, (2) a polymer surface layer and (3) a final polyurea armor layer.

Place cap consisting of two layers, Layer A and Armor Stone. Layer A cap consists of dredged material from Duluth Anchorage Area navigation channel. Place Layer A cap and then place with Armor stone.  Ongoing surveys by the Government will be done after each construction feature is installed to Demobilize. Remedial footprint: 2.8 acres

All sections are composed of three layers of stone: armor, core, and bedding. The armor layer is comprised of minimum two layers of ten (10) ton rock at the head sections and five (5) ton rock at the trunk section with structure side slopes varying from one (1) vertical on three (3) horizontal at the head section to one (1) vertical on two (2) horizontal at the trunk section.

The armor stone thickness will be increased from one armor stone layer to a minimum of two armor stones at all locations within the repair area for an armor stone depth of approximately 9 feet. Existing 6–10-ton armor stone in the repair area in good condition will be reused in the jetty structure, and existing 3-4 ton armor stone will be used to construct the new toe.
