Utility Locating Sample Clauses

Utility Locating. UIA will provide utility locating services directly or via sub-contractor for the City Network through the duration of this Contract.

Utility Locating. Contractor is responsible for contacting the utility location service and verifying completion of inspection prior to commencing work. Stipulations regarding entrance electrical service and rights-of-way are to be referred to the Director of the corresponding City of Ocala Department.

Utility Locating. Our subconsultant, SiteScan, who has an office in Rancho ▇▇▇▇▇▇▇, will investigate and mark depths of existing utilities within the 9 streets identified on the attached spreadsheet potentially requiring full reconstruction. These depths will be used to evaluate conflicts between shallow existing utilities and the proposed reconstruction alternatives. SiteScan will also identify the locations of the underground utilities on Rossmoor Dr from Bronwood Wy to ▇▇▇▇▇▇▇▇▇▇ Wy. SiteScan will perform an investigation of existing utilities within the roadways identified on the spreadsheet. Their technicians will utilize various non‐destructive techniques to identify the location of existing utilities. Geophysical equipment may be used including GPR, Electromagnetic Locators, Ram Rods, etc. to assist in locating lines. Where geophysical equipment is utilized, the investigation will be performed to identify utilities to quality Level B as defined by the University of Purdue guidelines for quality levels produced by Ground Penetrating Radar. The utilities identified during the investigation will be marked out onsite following the American Public Works Association (APWA) guidelines for the marking of utilities. APWA industry standard colors will be used to mark the locations directly on the surface. Nonpermanent water‐ based paint will be used where permitted. Where paint is not permitted (such as finished decorative surfaces or high traffic customer areas) chalk, wax or other materials may be used.

Utility Locating. Vacuum Excavation (potholing of potential utility conflicts) o Vacuum excavate 16 pothole locations to confirm underground utilities per conceptual 30% drawings. Backfill potholes with class II aggregate and repair 16 asphalt locations with cold permanent patch. o Asphalt repairs will be 1' x1' only or size of potholes with cold permanent patch hot asphalt restoration not included. o Pricing assumes eight hour working window and night work. o Work is assumed to be outside of surface “paint” areas of roadway and paint removal and replacement is not included. o Permit fees will be billed to and paid directly by City. • Alternate Utility Locating Options o If Vacuum Excavation is deemed not feasible or if alternative methods are better suited based on site specific conditions identified during 30% design (i.e. ground penetrating radar, sonde locating, etc.), Consultant shall present option to Client for approval in lieu of vacuum excavation.

Utility Locating. The Contractor is responsible for contacting the utility location service and verifying completion of inspection prior to commencing work. Stipulations regarding entrance electrical service and rights-of-way are to be referred to the Director of the corresponding City of Ocala Department. The maximum acceptable lead time on materials is two (2) weeks. The City shall issue a Notice to Proceed (NTP) upon notification of receipt materials by Contractor.

Utility Locating. Before performing any subsurface exploration work, we will make a one-call utility locate request to mark publicly-owned on-site utilities. It should be noted that any privately-owned underground utilities at the site will not be marked by the public locating service. For this reason, we will also hire a private utility locating service to supplement the public locate. Private utility locating services are able to mark electrically conductive utilities, such as power lines, steel water and gas lines, and plastic pipes with clearly visible trace wires. This proposal includes costs for completing a shallow vacuum truck assisted shallow excavation at each boring location. The vacuum truck assisted excavation will be completed to depths of about 4 to 6 feet and will have a similar dimension to the proposed borings. This excavation method is proposed due to the presence of numerous underground utilities in the project vicinity. Even private utility locators are not able to mark non-conductive utilities, such as plastic water and sewer lines, plastic irrigation and drainpipes, plastic gas lines, fiber optic cables, and concrete

Utility Locating. For streets that require full depth reconstruction, where excavation will extend below the existing structural section, ▇▇▇▇▇▇ will gather utility depths by electronic locating and potholing. Scope of this work will be deter- mined based on the treatment selections in previous task.

Utility Locating. 1. Perform or cause to be performed utility locating services to generally locate subsurface utilities utilizing not destructive techniques and the following equipment. The utility locating services is not a substitute for completely exposing subsurface utilities by means of hydro‐excavation which may be required upon completion of the locating services and commencement of engineering design services where conflicts should come to light. Hydro‐excavation services is not included in the utility locating services. • 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. • 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.
