Division I – Special Provisions

I Location/Site Description

The project is located Northeast of the City of Weston, Lewis County, WV, off Berlin Road. The main area of concern is a large drainage channel that is capturing water from above the Harrison property and depositing at a point near their garage/outbuilding and it is scouring out an area, fills it with water, then overflows, flooding the building on the Harrison’s property. This same drainage has undermined the pumphouse for the Hicks residence and may cause the structure to fail.

During heavy rains, water overflows a DOH culvert on Berlin Road and an adjacent access road for property owners.

The purpose of this project is to install above grade drainage channels and a below grade stormwater system to divert water away from the properties and structures. The highwall and unstable areas will be reclaimed with toe key foundations and bonding benches. The contractor will be responsible to plan the repair and revised drainage conveyance. The contractor will also be responsible to plan the sequencing of their Work and access considerations such that the

Contractor can comply with these requirements, the Limits of Disturbance shown on the Plans, and all other requirements in these Specifications or in the Plans.

3.2 Materials

The Contractor shall submit a minimum of two (2) copies of shop drawings, catalog cuts and material certifications (as applicable) to the Engineer for all offsite materials to be incorporated into the Work. At least 1 copy submitted must be electronic. Written approval from the Engineer will be required prior to incorporation of these items into the Work.

The Contractor shall submit a copy of the certifications of all technicians prior to any testing and at least two (2) copies of the results of all tests conducted on in-situ material, concrete, and grout to be used in this project. At least 1 copy must be electronic.

At a minimum, the pipe / fill compaction tests will include moisture content and density tests of the soil in accordance with the provisions of ASTM D698 (Standard Proctor) field density tests following compaction. A new Standard Proctor will be run when soil type changes occur on site and/or at the direction of the Engineer or State representative.

Soil tests shall determine the optimal additives required for areas of soil disturbance to be fully re-vegetated (see Section 6.0 of these Specifications). Normally, this includes – at a minimum – soil pH test results as well as available nutrients within the soil, including, at a minimum: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (MG), and Sulfur (S). At a minimum, the soil testing report will recommend what soil amendments in which concentrations are ideal for regrowth. If problems with re-vegetation occur, additional, more specialized tests may be required to be performed at the Engineer’s discretion and the Contractor’s expense.

Limestone and Sandstone shall be subjected to a Sodium Sulfate test in accordance with

AASHTO T104. Limestone shall be tested for calcium carbonate equivalent. Stone shall have a maximum weighted loss of twelve (12) percent when subjected to five (5) cycles of the Sodium Sulfate Soundness Test – ASTM C88 (ASTM C88-05 Standard Test Method for Soundness of Aggregates by Use of Sodium Sulfate or Magnesium Sulfate), as modified by AASHTO T-104. All stone shall be commercially supplied and shall be tested for calcium carbonate equivalency.

Limestone shall be commercially supplied and have a calcium carbonate equivalency of

70% or greater and be certified as such. The stone shall consist of particles of clean, hard, tough, durable rock, free from adherent coating. The State reserves the right to reject limestone based on a visual inspection without waiting on testing results.

Sandstone shall be certified to be non-acid producing. Sandstone to be sound, non-acid producing, durable, non-calcareous sandstone from a State approved source. Shale is not acceptable. The sandstone shall consist of particles of clean, hard, tough, durable rock, free from adherent coating. The State reserves the right to reject sandstone based on a visual inspection without waiting on testing results.

Note that the WVDOH Standard Specs and the MM-109 (if applicable) specify quality control and testing procedures that ARE REQUIRED for any applicable asphalt replacement repaving, shoulder stone, guardrail replacement, etc. The Contractor is to ensure these are implemented, that materials and installations permanently installed meet or exceed all required tests, and the Contractor shall provide the results to the State and the
