Technical Specifications Summary: 7th Street Drainage Improvements
This technical specifications document, prepared for the Borough of Red Hill in Montgomery County, Pennsylvania, outlines the comprehensive requirements for the 7th Street Drainage Improvements project. The project scope includes the installation of stormwater infrastructure along W. 7th Street between Gravel Pike (S.R. 0029) and Graber Alley, consisting of replacement of existing storm pipe with 18-inch Reinforced Concrete Pipe (RCP), connection to existing storm structures, installation of a new storm manhole and inlet, and restoration of pavement, concrete curbs, and sidewalks. The specifications detail 16 major construction sections encompassing general requirements, landscaping, excavation, erosion control, drainage structures, asphalt paving, concrete work, and record documentation. The project requires completion within 30 calendar days from issuance of the Notice to Proceed. The base bid includes mobilization, maintenance and protection of traffic, temporary erosion and sediment controls, drainage improvements, concrete improvements, asphalt pavement restorations, and grass restorations, with mobilization capped at $10,000 and maintenance and protection of traffic charged as a percentage of lump sum based on project completion progress.
The specifications require the contractor to furnish all necessary insurance, performance bonds, and payment bonds prior to mobilization and physical construction commencement. All work must comply with Pennsylvania Department of Transportation (PennDOT) Publication 408 specifications and standards unless otherwise modified herein. The contractor bears responsibility for construction layout, utility coordination, preconstruction video documentation, and compliance with Pennsylvania Act 172 excavation protection requirements, including notification to PA One Call at least 72 hours prior to excavation. Costs for all incidental work, including traffic control, dust control, grading, erosion control, and cleaning and restorations, must be included in unit prices for various bid items with no separate compensation. The contractor provides a 24-month maintenance bond guaranteeing materials and workmanship for asphalt resurfacing work and must provide record documents prepared through field surveying to verify as-built conditions prior to project closeout.

a. All areas designed for lawn shall be clean and free of all weeds and debris. Any debris greater than 3/4" in diameter, such as stones, sticks and construction waste material, shall be removed after tilling and discing so as to leave the surface smooth, even and free of roots.
b. It shall be the responsibility of the Contractor to see that all areas designated for lawn have a minimum of 4" of topsoil. Any areas not meeting this requirement will be brought up to minimum standards by the Contractor before proceeding with the work.
c. The subgrade must be loosened to a depth of 4". All debris over 3/4" in diameter brought to the surface by this operation shall be removed before proceeding with the spreading of the topsoil. No heavy equipment will be permitted on the lawn area after this work has been done.
d. If compacted, those areas which already have the required 4" minimum of topsoil shall be loosened to the 4" depth. Any debris 3/4" in diameter or over, brought to the surface by this operation, shall be removed.
e. Soil Improvements: Upon all areas for lawn, apply agricultural limestone uniformly with a mechanical spreader at the rate of 50 lbs. per 1,000 sq. ft. Incorporate these elements into the 6" of topsoil. Then apply complete 10-6-4 fertilizer at the rate of 20 lbs. per 1,000 sq. ft. Rake the entire area lightly before sodding and seeding.

8) Lay fabric smoothly on surface, bury top end of each section in four (4) inch deep excavated topsoil trench. Provide 12 inch overlap of adjacent rolls.
Backfill trench and rake smooth, level with adjacent soil.
9) Secure outside edges and overlaps at 36" (thirty-six inch) intervals with stakes.
10) Provide seed mixture in containers showing percentage of seed mix, year of production, net weight, date of packaging and location of packaging.
11) Prepare subsoil to eliminate uneven areas and low spots. Maintain lines, levels, profiles and contours. Make changes in grade gradually
12) Remove foreign materials, weeds and undesirable plants and their roots.
Remove contaminated subsoil.
13) Scarify subsoil to a depth of four (4) inches where topsoil is to be placed.
Repeat cultivation in areas where equipment, used for hauling and spreading topsoil, has compacted subsoil.
