AMENDMENT 0001

Interested Contractor Questions and Answers (Q&A)

Q1: Is a Master Plumber license required?

A1: See Revised SOW, Paragraph 1.5 Submittals, Section SD-03 that deletes “Master Plumber Qualifications”.

Q2: If you do require a Master Plumber on this project, are we allowed to outsource that requirement?

A2: See A1 above. No Master Plumber is required.

Q3: Am I correct in understanding that the septic tank will be fully pumped 24-hours prior to our project start time thereby ensuring two project starting conditions: no sludge or grease will be in the tank and local permit filings for septic pumping will have been completed?

A3: See revised section 1.4.2 (highlighted) of the SOW.

Q4: Are there any specifications regarding the septic tank visual inspection?

A4: The Corps is unaware of standards for a septic tank inspection. The goal is to get enough pictures and video of as much of the tank interior as possible to determine the structural integrity of the tank;

pictures for cracks and deterioration, video for seepage/flow.

Q5: Is there a standing "waste disposal plan" or a pre-coordinated dump site?

A5: See revised (highlighted) SOW.

Q6: If the disposal plan is approved post-contract award, do you already have a relationship with a local dump site that we can leverage?

A6: The Corps does not have any relationships with a local dump site.

SCOPE OF WORK

PART 1 GENERAL

1.1 SCOPE OF WORK

The US Army Corps of Engineers, St. Paul District (Corps) requires a Contractor to provide all labor, material, and equipment necessary for condition assessments of the Mel Rieman Recreation Area (MRRA) Visitor Center sewer pipeline and septic holding tank that supports shower and restrooms only. The MRRA Visitor Center and Campground is a 70-acre facility on the shoreline of Lake Ashtabula, 114th Ave SE, Valley City, North Dakota.

The MRRA septic holding tank and much of the pipe are below the water level of the dam. The septic holding tank has a history of becoming full in decreasing time intervals. Significant Infiltration/Inflow (I/I) of groundwater is suspected. When the tank is pumped out, Corps staff can hear water immediately pouring in. In addition to I/I Inspection to determine the reason for the increasing rate of fill, the Contractor must determine the overall condition of the sewer pipeline and septic holding tank. The work includes remote televising and recording via closed-circuit television (CCTV).

1.2 SYSTEM DESCRIPTION

The sewer pipeline runs from the Mel Rieman Visitor Center to a septic holding tank. The pipeline consists of seven (7) straight segments with turns at six (6) manholes. The original pipe was 1021 ft of 8 in.

vitrified clay pipe installed in late 1971. In July 1995, the clay pipe was slip-lined with 6 in. SDR-35 PVC pipe, except for the 240 ft section between MH3 (manhole #3) and MH4.

The 10,000-gallon septic holding tank is a component of a decommissioned sewage treatment system.

1.3 DEFINITIONS

1.3.1 Cleaning

To remove soil or solid deposited materials from a pipe segment when the pipe is less than half-full to full of deposited materials.

1.3.2 Defects

Defects in the pipe, manholes, structures, and services include cracks, separation of joints, collapsed pipe, grade irregularities, leaks, roots, grease buildup, offset joints, reverse grades, obstructions, delamination, missing pipe, restrictions, fractures, and similar structural irregularities.

1.3.3 Entry Point

The leading edge of the access point or the manhole or structure wall where the pipe segment begins. Only the pipe is video inspected from manhole or structure wall to manhole or structure wall and does not include any portion of the manhole or structure.

1.3.4 Exit Point

The point where the downstream access manhole or structure wall is encountered. Only the pipe is video inspected from manhole or structure wall to manhole or structure wall and does not include any portion of the manhole or structure.

1.3.5 Hydraulically Propelled Cleaning Tools

Tools that depend upon water pressure to provide their cleaning force.

1.3.6 National Association of Sewer Service Companies (NASSCO)

National Association of Sewer Service Companies (NASSCO) identifies the generally accepted industry standards for CCTV inspection, observation coding, and certification.

1.3.7 Pipe Segment

The length of pipe from entry point to exit point along the main or service.

1.3.8 Pipeline Assessment and Certification Program (PACP)

A CCTV Inspection standardization certification and observation coding system sponsored by NASSCO.

1.3.9 Point Repair

The location of a failure where a repair has occurred.

1.3.10 Re-TV Inspection

Refers to rework for a CCTV inspection that has video interruptions, gaps, or is not continuous.

1.3.11 TV Inspection Log

Information collected and recorded by the CCTV operator for each CCTV inspection effort and includes pertinent information for the respective inspection section, such as; date of inspection, location of site, CCTV technician, direction of CCTV inspection with manhole or structure identifiers, weather conditions, pipe size(s), pipe materials, conditions found, locations where the conditions were found.

1.4 ADMINISTRATIVE

1.4.1 Pre-Quote Site Visit

Contractors are encouraged to visit the site prior to quoting. Visits must occur during normal business hours and must be scheduled in advance with:

Joel Zietz

Maintenance & Repair Coordinator Mel Rieman Recreation Area

(701) 845-2970 Ext. 5613 Joel.E.Zietz@usace.army.mil

Hours: 8:00 am – 3:00 pm, Monday – Friday, excluding weekends and Federal Holidays

1.4.2 Pre-Inspection Meeting

The Contractor will contact the Contracting Officer’s Representative (COR) and arrange a virtual pre-inspection meeting.

a. Scheduling of work. A Work Schedule must be submitted and approved by the Contracting Officer to allow the COR to arrange delivery of portable restrooms during Visitor Center closure. The Contractor will not be responsible for portable restrooms.

b. Timing of Visitor Center water shut-off. The Visitor Center is the only source of flow into the sewer pipeline, other than I/I. The outdoor shower near the beach percolates water into the ground and does not drain into the sewer pipeline.

c. Timing of emptying the septic holding tank. After Visitor Center water shut-off, the septic holding tank will be emptied. The Corps has a contract with a pump truck service and will schedule this service at Corps’ expense to be performed at the optimal time(s) agreed upon by the inspection Contractor and the Corps during this pre-inspection meeting. The timing of this action can be used to determine the existence and rate of I/I by checking water depth after a prescribed waiting period.

d. Access to electricity and water valves in the Visitor Center.

e. Reservation of vehicle and equipment parking areas.

1.4.3 Disposal Plan

Disposal of all waste materials shall be done in accordance with all applicable Federal, State, and local waste disposal requirements. Note that this sewer and septic system is for showers and restrooms only.
