QUESTIONS AND ANSWERS

1.Previous projects have required a concrete pad, labeled UFAS Units, for selected trailer locations. Please clarify if these are required for this project. If so, provide detail and count of how many required.

UFAS concrete pads as installed on previous sites are not required as part of this contract.

2. Will you provide the wastewater treatment plant drawings so we can price the install?

See revised plans and specifications. WWTP will be furnished and installed by government.

3.Site Supervision – I do not see specification 01-45-00.00-10 Quality Control or specification 01-35-26 Governmental Safety Requirements in the SOW. These specifications typically outline the need for full time SSHO, QCM and Site Superintendents.

Are we required to supply all (3) full time managers or is site management at our discretion?

See revised specifications.

PART 3 EXECUTION

3.1 PROOF ROLLING

All road, MHU or RV pads, parking pads, areas below structures (i.e. treatment plants, bus stop shelters, etc.) will be proof rolled with a loaded dump truck in the presence of the Government’s on site QA representative.

Proof rolling shall consist of 1 pass in each traffic lane, or 1 pass for each 12’ width of road way (10’ road = 1 pass, 14’ road = 2 passes, 25’ road = 3 passes, etc.). One continuous pass, parallel to the road and perpendicular to lots, will suffice for MHU or RV pads and parking pads where road subgrade did not require repair or replacement.

Where failing deflection is observed within the footprint of an MHU/RV pad and associated parking pads during single pass perpendicular proof rolling, additional passes covering the entire footprint may be required at discretion of the Government’s on site QA representative.

Observed deflections, both recoverable (pumping) or non-recoverable, exceeding the following shall constitute a subgrade failure which necessitates repairs.

Road Subgrade: 2”

Parking Pads: 2”

MHU/RV Pad: 3”

Below miscellaneous structures: 2”

3.2 COMPACTION

Unless otherwise specified on the drawings or noted herein, compact soils as required to meet minimum proof roll testing. In areas where proof rolling is not required, compact soils to provide a surface suitable for the intended use.

At a minimum, track in all fills in lifts not to exceed 12” thick. Additional compactive effort, such as drum rolling or vibratory plate type equipment may be required in order to stabilize fill areas in order to exceed minimum compaction/deflection testing limits.

Where compaction efforts are required, prepare and compact a test area in the presence of the on-site QA. Vary speed and vibratory frequency to achieve effective compaction in a single pass. Where wet soil conditions are present, begin test with no vibratory efforts. Maintain speed and vibratory settings while soil conditions remain constant. Where a change in soil conditions are observed, repeat test procedure and continue with new speed and vibratory settings.

Exercise caution to avoid over-working / vibrating soils, particularly in wet conditions.

Refer to LDOTD requirements for compaction testing methods, densities, and frequency for all encroachments into public R/W, such as driveway or utility connections.

3.3 ROAD SUBGRADE

Refer to plan notes for subgrade preparation. Where additional repairs or stabilization to subgrade is required, refer to methods in LDOTD standard specification section 305- Subgrade layer.

3.4 MOBILE HOME / RV SITES

All work shall implement best management practices for erosion control and in accordance with applicable permits, state, and local requirements.

3.6 EROSION & SEDIMENT CONTROL

The Contractor shall be responsible for sediment and erosion control, including payment of any fines leveed by state or local authorities. The contractor shall procure all necessary sediment and erosion control permits. Any erosion and sediment control measures shown on the Plans are for the contractor’s convivence in obtaining required permits and are not intended to be representative of the extent of requirements to comply with permits or regulatory authority requirements.

PART 3 EXECUTION

3.1 EXCAVATION

Unless otherwise indicated, trench excavation shall be by open cut except that short sections may be jacked or bored if the utility can be safely and properly installed and ground loss can be properly controlled. All excavation shall be constructed in accordance with the Safety and Health Requirements Manual (EM 385-1-1) and OSHA Standards (29 CFR 1926). Allowable trench widths, depths, side slopes, sheet and bracing requirements, and other considerations are given in the OSHA Standard; and an abbreviated version is given in the Safety and Health Requirements Manual. During excavation, material satisfactory for backfilling shall be stockpiled in a neat and orderly manner at a sufficient distance from the banks of the trench to avoid overloading and to prevent slides or caving.

Topsoil shall be stockpiled separately from suitable backfill material. Grading shall be done as may be necessary to prevent surface water from flowing into the excavation, and any water accumulating therein shall be removed to maintain the stability of the bottom and sides of the excavation.

3.2 BOTTOM PREPARATION

The bottoms of trenches shall be accurately graded to provide uniform bearing and support for the entire length of pipe. Remove all rocks and other materials which may cause pressure points.

Hand excavate for bell ends. Pipe shall not bear on bell ends.

3.3 BACKFILLING AND COMPACTION

For trenches backfill, common backfill above the bedding shall be placed in 6" lifts and compacted with special purpose compaction equipment. Compaction equipment shall be selected to avoid damage to the pipe.

3.4 BURIAL DEPTH

Unless otherwise shown on the plans, trenches shall be of a depth listed by the local government to provide the minimum specified cover from indicated finished grade to the top of the pipe, cable or conduit. In the absence of plan notations or local guidance minimum burial depth of specific utilities is given below:

Water lines: 18 inches Sanitary Sewer: 18 inches Electrical wiring in conduit: 18 inches or as required by other governing authority
