About this file

Written by GovTribe AI ·

This is an Appendix document containing estimated unit price quantities for the Sand and Spring Run Subsidence Repair project (F-001-260-004) in Maryland. The project encompasses stream restoration and environmental remediation work across multiple zones including in-stream structures, lower and upper stream banks, and forested floodplain areas. The scope of work includes site preparation, mobilization/demobilization, construction layout staking, installation of erosion control measures (compost filter sock, stabilized construction entrance, stream diversions), channel excavation and embankment placement totaling approximately 620 cubic yards, reconstruction of boulder structures (J-hooks and vanes), stream channel riffles backfilling (255 linear feet), grouted riprap channel backfill (60 cubic yards), and toe wood repair and extension with live brush layering (395 linear feet combined). The project also includes significant planting and revegetation components with 2,560 two-inch plugs, 138 one-gallon trees and shrubs, seeding using native meadow mix and habitat mix (totaling 47 pounds), biodegradable erosion control matting (1,900 square yards), temporary seeding (316 pounds), and straw mulching (189 bales). Material deliveries include AASHTO-specified stone aggregates and riprap in various classifications.

The document serves as a reference pricing schedule that outlines estimated quantities for bid preparation purposes. No specific pricing, contract terms, award dates, or renewal options are detailed in this quantity estimate appendix. The quantities are organized by work category and unit type (lump sum, linear feet, cubic yards, each, pounds, square yards, tons, and bales) to facilitate contractor estimation and bid submission. This reference document establishes the scope and scale of materials and labor required for the subsidence repair and stream restoration project without establishing final pricing terms or contract award conditions.
