Professional Well Installation Services: White Marsh Park

Revised Scope of Work, Section I, of the Invitation to Bid: 11.5.25

This revised document shall replace the original Section I in its entirety.

I. SCOPE OF WORK (Addendum 1 revisions shown in red.)

This Invitation to Bid is to obtain licensed professional well installation services to establish a potable water source for a restroom at White Marsh Park.

The restroom will be fully conditioned and will serve a public athletics park year-round. Park usage is estimated at approximately 181,000 visits per year, for approximately 500 visits per day.

However, peak usage can reach 2,000 visits daily when tournaments are hosted. Based on a similar park with similar usage rates and the opinion of our Sanitary District staff, sewer and water service of 250 gpd will be adequate, but our system requirements must be capable of scaling to 500 flushes per day.

The successful bidder will be responsible for all aspects of well installation, including permitting and inspections from AHJ’s, excavation, connection to a constant pressure pump, and stubbing the water line for future connection. Fixtures to be served by the well will include a urinal, 5 toilets, 4 sinks and a wash sink, water fountain and exterior hose bib.

Manufacturer’s specifications for connections to the restroom building are provided in the

Appendix. A draft site plan, architectural drawings and a separate sheet for plumbing details, P2.01 labeled PLUMB2.pdf (new as of this Addendum 1) are provided as Appendix items.

All work shall comply with local codes, and the contractor shall be responsible for all necessary permits and inspections. The contractor shall provide all labor, tools, supplies and equipment necessary to complete the required work.

Work will be required prior to and following installation of the concrete building in May 2026.

All work leading up to the final connection to the new building will be completed no later than

April 1, 2026.

The successful bidder will be responsible for the following tasks:

1. Site Assessment and Planning

1.1 Conduct a site assessment to determine optimal well location based on soil conditions, water table depth, and engineering specifications provided in the bid package.

1.2 Develop a work plan that includes the layout of the well, pump, and water line, ensuring it complies with local regulations and best practices for park facilities.

1.3 Well is to be completed, developed and grouted according to state regulations.

Flow Test is to be done to determine permanent pump setting. Supply and install one pitless adapter capable of handling both the pump weight and flow rate needed of 40 15 gallons per minute.

1.4 Provide a timeline for permits and the construction schedule within 2 weeks after notice-to-proceed and weekly status updates thereafter to the Project

Manager.

1.5 Access to the site shall be provided by Queen Anne’s County with a gravel entrance just west of (approx. 450 linear feet from) the future well location. That distance is an unused field.

1.6 Electrical power to the site is expected to be installed and available for connection in early 2026. Beginning January 2, 2026, the Contractor will receive regular updates should any delays beyond that date emerge.

1.7 Site stake-out will be handled by Queen Anne’s County.

2. Permitting and Application Management

2.1 Obtain all necessary permits for well drilling and water service installation at the park site, including any health department and environmental clearances as required.

2.2 Submit applications for establishing a new well, manage inspections, and ensure that all regulatory requirements are met for well activation on April 1, 2026.

2.3 The Contractor shall provide to the Project Manager copies of permit application paperwork at the time of application and advise of the ongoing status of all necessary applications on request.

2.4 Application to Maryland Department of the Environment for an

Appropriation Permit shall be completed by December 1, 2025 or within 2 weeks of the Notice to Proceed, whichever is sooner.

3. Well Drilling and Casing Installation

3.1 Drill and install a well to the specifications outlined here, considering optimal depth and yield for a public restroom facility.

3.2 Install well casing and other structural supports to ensure stability, meet all code requirements, and protect the water source from contaminants.

4. Constant Pressure Pump Installation

4.1 Install a constant pressure pump suitable for public restroom use, ensuring it is compatible with the well specifications and provides consistent water pressure to meet expected usage.

4.2 Connect the pump to a power source as needed and integrate it with the plumbing lines and an 80-gallon bladder tank of the restroom.

5. Water Line Installation and Stub-Up

5.1 Run a water line from the well to the restroom location, following engineering specifications for depth, pipe type, and insulation (if required).

5.2 Stub up the water line at the restroom site according to manufacturer’s specifications, leaving it ready for future connection to restroom fixtures. Note that a 1.25” water line at the point of building entry is specified on the plans.

6. Testing and Water Quality Assurance

6.1 Conduct initial testing of the well to verify water flow, pressure, and pump functionality.

6.1.1 Initial Pump Run: Run the well pump for a 24-hour clean-out period to flush out any drilling sediments or debris and to allow the well to stabilize.

6.1.2 First Flow Test: Before the 24-hour clean-out period, conduct a 4-hour flow test to assess the initial yield of the well under normal pumping conditions. Please note any changes in flow during this period.

6.1.3 Clean-out Period: After the initial 4-hour flow test, allow the well to continue running for a 24-hour clean-out period to ensure that all fine materials are removed from the well.

6.1.4 Second Flow Test: After the clean-out period, conduct another 4-hour flow test to assess the well's performance once it has been fully cleaned out and stabilized.

6.2 Perform water quality testing according to local regulations to ensure compliance with public health standards.

6.3 Submit results of flow and quality tests to the City/County for approval.

7. Documentation and As-Built Drawings

7. 1 Provide complete documentation of the well installation, pump setup, and water line route, including as-built drawings showing the location and specifications of all components.

7.2 Include a final report with testing results and recommendations for future maintenance or expansion.

8. Site Clean-Up and Restoration

8.1 Restore all disturbed areas to pre-construction condition, including filling trenches, leveling ground, and removing any debris.

8.2 Ensure the site is safe and accessible to the public upon completion of work.
