Project Location and Background: This Statement of Work is to take place at Facility 2110, Vehicle Maintenance at the Maryland Air National Guard (MDANG) of Martin State Airport, Maryland Air National Guard, 2701 Eastern Boulevard, Baltimore, MD 21220. For several years the weight of vehicles going in and out of the maintenance bays has caused the asphalt to sink where it meets the concrete at the maintenance bays. This repair will create a smooth transition for the vehicles entering into the bay and maintain the structural integrity of the pavement over time.

2.0. Specific Project Background:

2.1. Supply all equipment, material, and labor required to remove approximately 2,665 sf of existing pavement and replace with 6 inch thick reinforced concrete slab apron. This project is for the Maryland Air National Guard, Martin State Airport, and Baltimore, MD 21220.

2.2. Cost Proposal:

Provide a detailed cost proposal indicating costs and breakdown for: Saw-cut existing asphalt pavement to depth of 9 inches as defined on the site plan and removing pavement in proposed work area. Compaction of base to receive new concrete. Concrete type to be MDSHA Mix #6, reinforced with 6 x 6 – W1.4 x W1.4 (10X10) 21lb C.S.F. welded wire fabric as defined in Typical Slab Downturn detail on Site Plan. Expansion joints must be formed for every 15ft length of concrete apron and surface application of silcure (a clear water soluble, sprayable, and inorganic, sodium silicate based compound) by soft-bristled brush or broom to achieve curing.

New apron grades must match existing pavement to achieve positive drainage away from entrance areas.

2.3. Description of Work:

Saw-cutting existing asphalt pavement to depth of 9 inch as defined on the site plan and remove pavement in proposed work area. Compact base to receive new concrete. Provide a 3 inch compacted layer of #57 stones for sub-base. Contractor is required to submit no less than two test cylinders of concrete mix for laboratory testing. Acceptable compressive strength for concrete is 4500 psi at 28 days in accordance with ASTM C78 and ASTM C 192. This testing will be conducted by an independent accredited agency. The concrete pad is to be brushed/broom finished. The contractor shall develop and institute approved measures to prevent plastic shrinkage cracks from developing by adherence to proper curing process. Reinforcement will be as shown to include 6 x 6 – W1.4 x W1.4 (10X10) 21lb C.S.F. with 2 inches cover. See Typical Slab Downturn detail on Site Plan. Expansion joints must be formed for every 15ft length of concrete apron and surface application of silicure (a clear water soluble, sprayable, and inorganic, sodium silicate based compound) by soft-bristled brush or broom finish to achieve curing. Expansion joints to be rubberized asphalt fuel resistant, hot applied, except at location where perimeter wall is adjacent to pour use asphalt impregnated fiberboard. The isolation joint at the perimeter walls must go all the way through the slab starting at the subbase. The top part of the preformed filler will be cut off and the space filled with elastomeric sealant.

New apron grades must match existing pavement to achieve positive drainage away from entrance areas. All disturbed areas must be graded to provide positive drainage to the catch basins.

Contractor will maintain the integrity of all existing bollards within the excavated areas and provide thirteen (13) new bollard sleeves (safety yellow) 8.75inch dia. installed after the concrete apron completion. Sleeves covers (4’-6” approx. height) to be Impact-resistant HDPE firmly installed. All touch-up, repair or replacement of damaged products to be achieved before substantial completion.

The work shall be installed in accordance with this specification and best industry practices.

2.5. Cutting and Patching Proposal: Submit a proposal describing procedures at least 7 days before the time cutting and patching will be performed, requesting approval to proceed.

2.5.1. Cut in-place construction to provide for installation of other components or performance of other construction, and subsequently patch as required to restore surfaces to their original condition.

2.5.2. Use materials identical to in-place materials. For exposed surfaces, use materials that visually match in-place adjacent surfaces to the fullest extent possible.
