Specifications include, but are not limited to: This project consists of, but is not limited to job meetings, submittals, removal and disposal of existing brick and granite pavers and subbase, complete removal of two trees, subbase excavation and installation of new gravel base and installation of new concrete sidewalks. Limits of new concrete sidewalk will be the same as the existing brick pavers. Fencing and/or barricades will be required to protect both construction work and the public. Cleanup, topsoil, seeding, and mulching will be done as soon as possible. All work shall be coordinated with BGS and the State Rest Area representative, and access to the building must be maintained at all times, utilizing the rear entry door on a limited basis. Work shall be substantially complete by 05/08/20 and progress uninterrupted until completion. The contactor shall restore the lawns, including repairs, grading, seeding and mulching as needed. Sidewalk work shall consist of constructing sidewalks of Portland Cement Concrete s on a prepared subgrade, in accordance with 2018 Vermont Standard Specifications and in reasonably close conformity with the lines, grades, and typical cross-sections shown. • The total existing square footage of brick pavers to be removed is approximately 1,100 square feet (sf) with an anticipated installation of approximately 1,100 sf of new Portland cement concrete sidewalk. Concrete shall be 4000 psi with 5% - 7% air entrainment. • Excavation shall be to a depth of twenty-one (21) inches from existing grade. • Sixteen (16) inches of three-quarter (3/4) inch minus crushed stone sub-base shall be installed and shall be thoroughly compacted in two (2) eight (8”) inch lifts. Compact gravel to 95% Modified Proctor Density. • New Portland Cement concrete sidewalk shall be installed at a depth of five (5) inches, including #4 rebar, 18” on center, each way, centered in slab. Sidewalks to have a fine broomed finish and tooled edges, and a cure and sealer shall be applied, Euclid Everclear VOX or equal. • A nine (9) by nine (9) foot by 5” thick concrete pad shall be poured over 16” of compacted gravel subbase where the existing picnic table exists, including #4 rebar, 18” on center, each way, centered in slab. • Place a tooled construction joint every 5’ to a depth of 1”. • Place expansion joints as needed and approved, not to exceed 20’ apart, with dowels 18” on center, and ½” thick resilient non-bituminous expansion material to a depth of 5”, Homex 300 or equal. Place expansion materials against foundation wall also. Revision Date: February 27, 2019 Page | 2 • Sidewalk to be doweled to the building foundation at 18” spacing. One end of the dowel to be greased. • A ½” galvanized eye hook shall be cast into the concrete pad to allow for securing of the picnic table. • A one (1) foot by five (5) foot Portland cement concrete pad (at a depth of five (5) inches) shall be installed at the gazebo entrance for pedestrian access. • Forms shall be of wood, metal, or other suitable material and shall extend for the full depth of the concrete. All forms shall be true to line, free from warp, and of sufficient strength to resist the pressure of the concrete without springing. Bracing and staking of forms shall be such that the forms remain in both horizontal and vertical alignment until their removal. • The Contractor shall construct, place, and maintain such barricades and protection devices as are necessary to keep pedestrians and other traffic off the sidewalk until it has fully cured. • Two (2) medium-size crab apple trees are to be removed and the stumps completely removed. • Landscaping shall be expected after forms and trees are pulled and sidewalk installation is complete, to restore the area to its original condition. Install a minimum of 4” of topsoil, and seed, mulch, and water as needed.
