PRE-BID QUESTIONS AND ANSWERS

Q1. How does the contractor determine when dewatering is complete?

A1. Refer to Section 9.3.1 of the Technical Specifications regarding construction methods of Mine Dewatering. According to the specifications, “Dewatering operations may cease when the water level in the existing piezometers indicate 1 foot or less of water from the mine floor.”

Q2. Why do the specifications require boring into the coal pavement for the dewatering holes?

A2. Refer to Section 9.3.1 of the Technical Specifications regarding construction methods of Mine Dewatering. According to the specifications, the bottom 20 feet of the 12-inch PVC casing pipe shall be perforated and shall socket 10-feet into the coal pavement to allow for placement of the Rotating Magnetic Ranging System (RMRS) sensor as described in the Specification Section 18.2.9.

Q3. How does the contractor abandon the vertical dewatering holes?

A3. Refer to Section 9.3.3 of the Technical Specifications. The piezometers and boreholes must be removed and abandoned by a person who has been certified by the State of West Virginia in accordance with 47CFR59 “Monitoring Well Regulations”.

Q4. Will there be any leniency in specs for HDD – for example using welded casing instead of threaded casing?

A4. Changes can be requested and submitted to the engineer for review.

Site is a former AML project that has continued to reveal additional concerns.

There are existing mine drainage features and grouted riprap channels that remain from the former project.

There are two Stabilized Construction Entrances. One is on the access road on the way up to the meeting area and the other is the access road that is to be used to access the underdrain located behind Mr. Lambert’s house.

Landowner’s have requested no work during Thanksgiving week and that we always provide a few days’ notice of when anyone will be at the site.

A MM109 Highway Occupancy Permit has been obtained for the Project. Traffic Control is to follow West Virginia Division of Highways Case A-6 which includes flaggers, cones, signage, etc. based on location and duration of working equipment.

Electric fence and controller are to be removed and provided to POTESTA.

If asphalt at bottom of Mr. Huffman’s road is damaged it will need repaired, same goes for existing gate. Gravel access road is to be regraded and surfaced with stone after construction. Concrete portion of access road is slated to be repaved with concrete.

Overview of Project Includes:

o Construction of HDD pad access road and removal of soil mass in area of landslide and cut slope above HDD access road. Soil removed from those areas shall be backfilled against highwall in accordance with design plans with drainage installed as noted on the plans. HDD Pad includes installation of Temporary Trap to be utilized during mine dewatering and HDD. This temporary trap is to be removed after HDD is completed with area being regraded as noted on plans for drainage control.

o Dewatering Mine prior to HDD. Dewatering Plan must be submitted to Potesta for review as a submittal. Two dewatering borings are proposed at each of the two HDD target locations. Depending on the findings of the first boring at each location, contractor is to discuss with POTESTA the need for the second boring. It is possible that only two dewatering borings will be required or there could be as many as 4 borings. Quantities are based on four borings but Contractor will only be paid for actual footages installed. Updated water levels compared to last year?
