Utility Mapping and Subsurface Utility Detection Salt Lake Community College Consultant Scope of Services and Proposal Requirements Project purpose Salt Lake Community College (SLCC) seeks consultant services to investigate, survey, and map existing utilities at the Redwood, South City, Larry H. Miller, and Jordan campuses. The completed work shall provide coordinated utility maps and geographic information system (ARCGIS) data for facilities management and future project planning. Survey products shall be delivered in PDF and editable AutoCAD. Civil 3D-dependent files are not acceptable.

Utility coverage The investigation shall address electrical distribution; culinary water; irrigation water mainlines; sanitary sewer; storm drainage; natural gas; telephone and communications; steam; and utility tunnels, where present within the agreed survey limits. Identify associated accessible features, including valves, meters, hydrants, manholes, inlets, cleanouts, vaults, and utility entry points. Distinguish utility tunnels entry and exit points and duct banks from the individual systems they contain. Clearly identify off-campus connections. Irrigation investigation and mapping are limited to mainlines and associated mainline appurtenances. Exclude lateral piping, branched distribution systems, sprinkler heads, and other downstream irrigation components.

Identify known active, abandoned, and out-of-service utilities when supported by records or field evidence. An unsuccessful detection attempt shall not be reported as proof that a utility is absent. Describe the proposed coverage, campus boundaries, building connection endpoints, and any excluded areas. Interior building distribution is not included in the survey.

Records review and coordination Review available utility drawings, previous surveys, record documents, and facilities information. Coordinate through the SLCC Project Manager (PM), with participation by each Campus Facilities Manager and relevant utility owners. Maintain a responsibility matrix identifying responsibilities for records, access, utility coordination, fieldwork, review, and delivery. Submit a work plan and campus sequencing schedule before fieldwork, including personnel, equipment, access requirements, survey control, and quality-control procedures.

Where the investigation includes utilities crossing city streets, obtain available location and depth information from the local authorities and private utility companies. Reconcile records with field observations and identify discrepancies for further investigation.

Investigation and survey methodology Subsurface utility detection Subsurface utility detection (SUD) means the field investigation used to identify buried utility alignments. Describe the proposed combination of electromagnetic locating, ground-penetrating radar, and other appropriate methods. Explain limitations associated with utility material, depth, soil conditions, congestion, inaccessible areas, and missing tracer wires. Select methods suited to each utility; reliance on a single detection method shall be explained.

Survey detected alignments and visible utility features into a common project coordinate system. Differentiate records research, surface observations, geophysical detections, and physical exposure. Reconcile conflicting evidence and preserve an investigation log identifying areas searched, methods used, unresolved features, and recommended follow-up work.

Utility information quality Identify the proposed and achieved utility information quality levels using the ASCE 38-22 framework, Quality Level A. Quality Level A establishes precise horizontal and vertical information at specific points through physical exposure and measurement.

Survey control and elevations Identify the proposed horizontal and vertical accuracy, coordinate reference system, datums, units, survey equipment, and verification procedures. Document the control points and benchmarks used, including their relationship to existing SLCC survey monuments. Verify the datum associated with SLCC’s USGS-based monument elevations before combining historical and new survey data.

Show utility depth or elevation as supported by the stated measurement method. Identify whether a value represents cover, top of utility, centerline, or invert, and distinguish instrument-estimated depth from exposed and surveyed measurements. Do not create assumed elevations to complete a three-dimensional model.

Additional investigation Identify unit costs for potholing or vacuum excavation needed to resolve critical uncertainties. Excavation, confined-space entry, utility operation, and service interruptions require specific authorization before proceeding. Describe any engineering services included and identify the responsible licensed professional.

Campus work requirements Access and occupied facilities Coordinate facility access with the SLCC PM and request keys or electronic access . Limit work in existing buildings to 7:00 a.m.–5:30 p.m., Monday through Friday, unless the PM approves another arrangement in writing. Coordinate weekend work and accommodate finals-week quiet periods, which may restrict work during normal business hours.

Provide at least two days’ advance notice of operations that create disruptive noise, vibration, or odors, and obtain the PM’s written permission before proceeding. Do not interrupt utilities serving occupied facilities without written approval. Give at least two days’ advance notice of a proposed interruption and identify any temporary service needed to maintain operations.

Maintain existing exits and access to walkways, occupied facilities, and emergency routes. Closures or obstructions require written SLCC permission and approval by the authority having jurisdiction. Provide durable, slip-resistant temporary walking surfaces where pedestrians must be rerouted and maintain accessible routes.

Excavation and site protection (as applicable) For authorized excavation, submit the SLCC digging permit request through Facilities Services Division Planning at least five working days before the planned digging date. Obtain a valid permit before digging. Complete utility-owner coordination and required excavation notifications before intrusive work; the mapping survey does not replace excavation clearance.

Protect open excavations outside an enclosed work area with a six-foot-high chain-link fence in good repair and locked access gates. Limit work and equipment to approved areas. Protect existing utilities, paving, landscaping, and irrigation, and repair damage caused by the work. Do not drive or park on turf without approved protective access measures. Locate and protect irrigation components before operating equipment nearby.

Review the field safety program with the SLCC PM before starting work. Provide appropriate protective equipment, signs, and barriers for the operations being performed. If hazardous materials are encountered, stop work in the affected area, notify the PM immediately, and do not resume until the PM authorizes it. Clean work areas and affected common areas daily and dispose of debris lawfully.

Project communication Keep the PM informed of progress, access restrictions, discrepancies, and conditions affecting scope or schedule. Document coordination decisions and distribute meeting notes. Obtain written approval before undertaking additional services or changing the agreed work limits, deliverables, or schedule.

Describe proposed departures from a stated requirement, the reason, the alternative, and its cost and operational effects. Submit the request through the PM for written disposition before implementing it.

Maps and digital deliverables Provide a composite utility map for each campus and separate utility layers or views. Include an Excel file of the campus, utility types, survey date, legend, investigation limits, and unresolved conditions. Show benchmarks and relevant known easements affecting the mapped utilities. Include north arrows, graphic and numerical scales, consistent orientation, and match lines where maps extend across sheets.

Deliver searchable PDF maps and an editable AutoCAD DWG , latest published version. Files shall remain usable without Civil 3D, Civil 3D object enablers, or unresolved proxy objects. Demonstrate compatibility with a representative sample before full production.

Draw CAD model geometry at full scale. Prepare sheet layouts for plotting at 1:1, with sheet origins at the lower-left border. Use coordinated origins, consistent utility layers and symbols, and filenames matching sheet identifiers. Supply original referenced files with XREFs attached rather than overlaid, plus bound archival DWG copies. Include linked images and other support files. Identify each delivery by project name, assigned project number, consultant, and issue date.

ARCGIS dataset and supporting information Provide georeferenced utility features with consistent identifiers linking maps and ARCGIS records. Include utility type, information source, collection date, verification method, quality level, and known size, material, and operational status. Mark unknown attributes explicitly. Supply a data dictionary, coordinate-system information, survey control records, relevant field photographs, and the investigation and limitations log.

Describe the proposed ARCGIS format and data structure, and confirm compatibility with SLCC before production. Check for duplicate features, broken or unsupported connections, geometry errors, and inconsistent attributes. Keep ARCGIS and CAD or Revit locations and identifiers coordinated. Identify hosting, software licenses, subscriptions, or ongoing support as separate services if proposed.

Review and completion Submit draft maps and data for SLCC review, correct errors, and address review comments before final delivery. Provide an itemized transmittal signed by an authorized consultant representative and a handoff meeting explaining file organization, use, and limitations. Completion requires usable files, agreed coverage and accuracy, coordinated attributes, and documented unresolved conditions accepted by SLCC.

Consultant proposal narrative Describe the proposed services in sufficient detail for SLCC to understand the investigation effort, resulting information, and limitations. Include comparable utility mapping experience, proposed personnel and subconsultants, applicable professional licenses, sample deliverables, and client references. Identify the personnel responsible for surveying, detection, ARCGIS development, and quality review.

Explain the methods proposed for each utility, the intended quality levels and accuracy, campus coverage, access assumptions, quality checks, and schedule. Identify anticipated SLCC assistance and any information needed to establish a reliable fee. Explain exceptions and additional services expressly, including any work dependent on utility-owner participation or separate authorization.

Cost breakdown by utility The fee proposal shall provide a separate total for each utility covering all four campuses: Taylorsville Redwood, South City, Larry H. Miller, and Jordan. For example, the electrical fee shall cover electrical utility work across all four campuses, and the culinary water fee shall cover culinary water work across all four campuses. A campus-only breakdown does not satisfy this requirement.

Each campus fee shall identify the cost of records, review and coordination, detection and survey, ARCGIS and drawing production, and quality review and final delivery. Allocate shared mobilization, control, and project management costs consistently, or list them separately once; do not duplicate them across utility totals.

Provide the combined base fee, exclusions, and separately priced optional investigations. For unit-priced work, state the unit, assumed quantity, unit price, and extended amount. SLCC will select individual utility assignments. Pricing is to be submitted by the submission deadline.
