About this file
This is a Surveying Specification Document (Section 01 17 21) for the Circuit 680 UG Cable Replacement Construction Services project administered by JEA (Jacksonville Electric Authority) in Jacksonville, Florida. The specification outlines comprehensive professional surveying and mapping requirements for approximately 1,200 feet of 69 kV underground cable replacement work occurring within the Dillion Substation, generation facility, and along Talleyrand Avenue and Wigmore Street in Jacksonville. The contractor must retain a Florida-licensed Professional Surveyor and Mapper, approved by JEA, to perform control surveys, construction layout, and As-Built drawings throughout the project. All surveying work shall comply with Florida Administrative Code 5J-17 Minimum Technical Standards and use NAD 83 as the horizontal and vertical datum. The surveyor must document existing utilities including water, wastewater, reclaimed water, storm water, communication, fiber optic, electric, and gas infrastructure, recording elevations and coordinates to two decimal places. Specific deliverables include a boundary survey with certified map and report, construction layout plans, and comprehensive As-Built survey documentation in both AutoCAD 16 (soft copy) and PDF (hard copy) formats submitted as preconstruction and closeout submittals.
Quality assurance measures include JEA's right to conduct random spot checks to verify survey accuracy, with requirements that if more than 10 percent of checks are inaccurate, the surveyor must uncover and reverify all work at their own expense and restore surfaces accordingly. The surveyor must coordinate with JEA to establish control points before field work commences and provide specialized support for horizontal directional drill (HDD) installation, including staking at minimum 10-foot intervals with depth identification and grade elevations. Any work installed but not recorded during construction must be surveyed post-construction at the contractor's expense, including surface restoration. The surveyor is responsible for locating, referencing, and preserving existing control points and property corners, resetting any disturbed monuments at the contractor's expense, and ensuring all construction layout staking is easily verifiable. All survey work products become the property of JEA upon completion.

SECTION 01 17 21
SURVEYING
08/26
1. GENERAL
1.1. Description: Professional Surveyor: Provide professional surveying and mapping work required for the execution of the Contract including, but not limited to, verification of existing survey data, construction layout, and production of the As- Built Drawings. All work shall be performed by a Surveyor that is licensed by the State of Florida as a Professional Surveyor and Mapper pursuant to Chapter 472, F.S.
Boundary Survey: Boundary survey, map, and report certified by a Surveyor and Mapper shall be provided that meets the requirements of Chapter 5J-17 'Minimum Technical Standards', FAC.
1.2. Requirements: The Contractor shall retain the services of a Professional Surveyor and Mapper licensed in the State of
Florida, approved by JEA, to provide professional surveying and mapping services necessary for investigation and/or construction including, but not limited to, a control survey. An As-Built survey shall be created and maintained during construction. The original survey was completed by Johnson Surveying, which used field monuments as the basis of the control points. The control points shall be verified by the Contractor prior to start of construction.
1.3. Submittals:
Provide qualifications of the Surveyor and Mapper:
SD-01 Preconstruction Submittals
Registered Surveyor and Mapper who is proposed by the Contractor to provide the services for this scope of work shall be acceptable to JEA prior to field services being performed.
Submit name, address, and telephone number of the Surveyor and/or Mapper, as appropriate, to JEA for acceptance before starting survey or mapping work.
Submit written acknowledgement from the Surveyor and Mapper stating they have the hardware, software, training, knowledge, and ability to provide the scope of services in the agreement with the Contractor to fully comply with the requirements of this specification and project requirements.
Submit copies of current licenses and registrations.
Submit proposed construction layout.
SD-11 Closeout Submittals
Submit documentation verifying accuracy of survey work
2. SURVEY DOCUMENTS
2.1. Survey Description:
2.1.1. All work, in all forms, shall become property of JEA.
2.1.2. The Surveyor and Mapper shall record elevation and coordinates (location) of all new and existing utilities, known and exposed, including, but not limited to, water, wastewater, reclaimed water, storm water, communication, fiber optic cable, electric, gas, and any other structures located within the limits of construction.
2.1.2.1. Piping/conduit shall be measured to the centerline and to the top of the pipe (T.O.P) or conduit and at every change in direction or elevation.
2.1.2.2. Slopes, where applicable, shall be recorded.
2.1.2.3. Valve elevations shall be measured to the nut operator (not the extension).
2.1.2.4. The top (T.O.D.B) and bottom (B.O.D.B) elevations of electrical duct bank shall be recorded.
2.1.2.5. Provide existing grade shots along the centerline of the utility route.
2.1.3. The Surveyor and Mapper shall record, to 2 decimal places, the elevation and location of all:
2.1.4. The Surveyor and Mapper shall submit a certified survey in both hard and soft copy version. Soft copy versions shall be submitted in AutoCAD 16 format. Hard copy versions are to be submitted in PDF format.
2.2. Quality Assurance:
2.2.1. NAD 83 shall be used as the horizontal and vertical datum.
2.2.2. The Surveyor and Mapper shall coordinate with JEA and schedule the establishment of the survey control points at the onset of any field work.
2.2.3. JEA intends on making random spot checks to verify accuracy of all survey work. If more than 10% of the spot
