RE: Utility Locating Services – 905 State Road 436 in Casselberry, Florida

Ms. Kovach, GeoTek Services is pleased to respond to your request for Utility Locating services at 905 State Road 436 located in Casselberry, Florida. We will scan a (10’ x 10’) area around the five proposed bore locations with the goal of locating underground utilities.

We can only scan the easily accessible open areas for utilities. Note that we cannot scan beneath fixed objects such as landscaping, fencing, buildings. We will scan as close as reasonably possible to fixed objects such as walls, landscaping, fences, etc.

Our deliverable will be marking paint and/or flags indicating the location of potential underground utilities. It is the client’s responsibility to protect and preserve all marks.

We will use both Electromagnetic Induction instruments as well as Ground Penetrating Radar (GPR) to detect objects below the surface. Due to the nature of sub-surface detection and the physical laws governing radio wave propagation, some buried objects may not be detectable due to depth, obscuration, or a weak radar signature. GeoTek Services will use industry standard best practices to locate sub-surface objects, however some objects may not be detectable. Geotek Services does not guarantee that all underground objects can be found. GeoTek Services assumes no liability for any damages.

We request access to any as-built site plans of the scan areas prior to rendering services. Our fixed price quote for this effort is $750.00. No out-of-pocket expenses are expected for this project. This quote is valid for sixty days.

Best Regards, Martin (Bud) Connor GeoTek Services, LLC

Quote Number: GPRSQUOTE-260714 floridainfo@gprsinc.com GPRS Opportunity Name/Number: 905 Florida Highway 436, Casselberry, Florida 32707 utility scan

GPRS appreciates the opportunity to provide this proposal. We encourage you to visit our website (www.gprsinc.com) and contact any of the numerous references listed. Our insurance certificate and W-9 can also be downloaded here. Please feel free to contact us if you have any questions or need additional information.

Scope of Work

Soil Bore Scan: We understand the scope of work on this project is to search for underground utilities around soil bores, as listed in the table below. We will attempt to trace any utilities for which structures are visible from the work area. Utilities will be marked on the surface using spray paint or other appropriate means. The client will be responsible for providing drawings or notifying GPRS of any utilities known to be entering the work area for which there are no apparent surface features or structures that are visible from the work area. To avoid additional charges, the areas should be laid out, marked, and cleared of obstructions prior to our arrival.

Soil Bore Count Scan Area Radius 5 Soil Bores 10 ft. radius around each

Equipment

• Underground Scanning GPR Antenna. This GPR Antenna uses frequencies ranging from 250 MHz to 450 MHz and is mounted in a stroller frame that rolls over the surface. Data is displayed on a screen and marked in the field in real-time. The surface needs to be reasonably smooth and unobstructed to obtain readable scans. Obstructions such as curbs, landscaping, and vegetation will limit the efficacy of GPR.

The total effective scan depth can be as much as 8’ or more with this antenna but can vary widely depending on the soil conditions and composition. Some soil types, such as clay, may limit maximum depths to 3’ or less. As depth increases, targets must be larger to be detected, and non-metallic targets can be challenging to locate. The depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link

• Electromagnetic Pipe Locator. This receiver can passively detect the signals from live AC power or radio signals traveling along some conductive utilities. Operators can connect a transmitter directly to accessible metallic pipes, risers, or tracer wires to generate a current at a specific frequency. The receiver can then detect the resulting signal along the pipe or tracer wire. Various factors may impact this device's effectiveness, including (but not limited to) access to the utility, conductivity, grounding, and interference from other utilities.

The depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link

• Traceable Rodder. The rodder consists of a copper wire encased in fiberglass. This device is pushed through a pipe with direct access, such as a sewer line at a cleanout or a storm drain catch basin. Operators then induce a current on the wire and trace the signal from the surface. The maximum traceable depth is 10’ depending on the soil conditions, and the maximum distance is 200’. Inserting the rodder into deeper pipes within manholes may not be feasible depending on site conditions. GPRS will not access electrical conduits. The signal is not detectable through metallic pipes. For more information, please visit: Link

• GPS. This handheld unit offers accuracy down to 4 inches; however, the accuracy achieved will depend on the satellite environment at the time of collection and is not considered survey-grade. Features can be collected as points, lines, or areas and then exported as a KML/ KMZ or overlaid on a CAD drawing. For more information, please visit: Link

Project-Specific Assumptions

• Standard full-day rates are based on an 8-hour workday. Time-on-site in excess of 8-hours will be billed at overtime rates.

• This price assumes that we will be given access to perform the work during weekday business hours (6am-5pm). Work performed outside of this is billed at time and a half.

• All of our technicians have OSHA-10 safety training or greater. Site-specific safety training is not included in this quote. Please notify us if this project requires additional safety training.

• As-builts and any other applicable drawings shall be made available to GPRS prior to the project.

• The equipment listed in this proposal is the standard recommended equipment for your project. Depending on site conditions, your GPRS Project Manager may use all of the equipment listed or a subset thereof on your project. At their discretion, they may also employ additional tools not listed above to provide you with the best results possible.

• A thorough utility search can only be completed if GPRS is given access to all utility structures, interior and exterior. This service is never a replacement for the use of the state One Call system (811).

• If your project includes scanning an elevated concrete slab: Some slabs may not be completely penetrable from the top only and would need to be scanned from both top and bottom and should be considered an unforeseen circumstance that would incur additional time onsite and charges.

• If your project includes scanning a wall or elevated concrete slab: Ladders, manlifts, or safe access for scanning wall or ceiling locations is the responsibility of the client.

• If your project includes scanning a concrete slab with roofing material or other surface obstructions, these obstructions should be removed by the customer or customer's representative prior to our arrival. GPRS will need direct access to the surface of the concrete to obtain optimal results.

• These rates assume that there are no certified payroll requirements. GPRS has not been notified of any PLA, DIR, or Certified Payroll requirements. If GPRS receives notice that any of these conditions exist, there will be additional costs.
