SCOPE of WORK

The scope of professional land surveying and survey monumentation services for the 2026 Overlay and Resurfacing Program (CI 5735) will encompass areas in Attachment A. Based on a preliminary search of recorded maps, there are estimated to be 824 survey monuments requiring preservation including 814 center monuments and 10 ties on curb ramps to be reconstructed.

Reports, memoranda, and other documents furnished under this Scope of Work must be of a quality acceptable to the City. Deliverables must: be of neat appearance, complete, accurate, error-free as possible, organized and technically and grammatically correct, reflect the incorporation of City and other agency review comments, and be checked to meet all of the contract requirements. Final documents shall be submitted to the City in hard copies, along with electronic files, upon completion or as otherwise directed by the City.

Below is the scope of work envisioned by the City. Based on the program budget the program scope of work may change (See Attachment A).

Task 1. Pre-Construction Surveying requirements

This task is to be completed prior to the commencement of construction activities:

1.1 Describe the type of survey instrument proposed for the surveying work.

1.2 Research and analyze existing centerline monuments and their associated centerline ties within the streets of the project and submit to the City a survey work plan and schedule for approval.

1.3 The preconstruction survey work shall set a minimum of three (3) centerline ties for each found existing recorded centerline monument and categorize in the following scenarios:

1.3.1 Found existing recorded monument that has three (3) ties. – No new ties required.

1.3.2 Found existing recorded monument that has two (2) ties. – Set one (1) new tie.

1.3.3 Found existing recorded monument that has one (1) tie. – Set two (2) new ties.

1.3.4 Found existing recorded monument that has no ties – Set three (3) new ties.

Optional Services (under Task 1.3):

Attachment C

1.3.5 Set a minimum of four (4) new centerline ties for each found centerline monument. This in essence requires one additional tie to set in each scenario above.

1.4 Provide the City with Pre-Construction Corner Record including depth information and sketch for each found monument and their associated ties with supporting documents on or before February 1, 2026.

1.5 Patch all holes caused by removing asphalt for preconstruction survey activities with cold patch material as approved by the City.

1.6 File the Pre-Construction Corner Record for each set centerline monument with the County Surveyor Office after City approval.

1.7 Provide the City with copies of all filed Corner Records.

Task 2. Post-Construction Surveying requirements

This work is to commence after construction of the project:

2.1 Describe the type of survey instrument proposed for the surveying work.

2.2 Re-establish the centerline monuments and set centerline monuments within the Project as directed by the City.

2.3 Edit the field sketches, where needed, to identify the re-established centerline monument.

2.4 Provide the City with Post-Construction Corner Records and sketches for each set centerline monument and their associated ties.

2.5 File the Post-Construction Corner Record for each set centerline monument with the County Surveyor Office after City approval.

2.6 Provide the City with copies of all filed Corner Records.

Task 3. Curb Ramp Monuments Preservation

This task is to be completed prior to the commencement of construction activities:

3.1 Describe the type of survey instrument proposed for the surveying work.

3.2 Provide a detailed proposal for preservation of the Curb Ramp Monuments.

3.3 Research and analyze existing curb ramp monuments within the streets of the project and submit to the City a survey work plan and schedule for approval.

3.4 Perform curb ramp ties preservation and provide the City with Corner Record for each found monument with supporting documents on or before February 1, 2026.

3.5 File the Corner Record for each monument with the County Surveyor Office after City approval.

3.6 Provide the City with copies of all filed Corner Records.

Task 4. Project Meetings:

Consultant shall prepare for and conduct the following meetings (may be via Zoom or Teams, or in person at City hall at sole discretion of the City), and shall prepare and distribute meeting agendas and minutes:

4.1 Project Kickoff meeting (allow 3 hours) – shall include project team introduction, and consultant presenting the project approach, schedule, etc.

4.2 Project progress meetings (three meetings at 2.5 hours each) – to be scheduled as deemed necessary by the City.

Assumptions:

1. Project construction start date is expected in March 2026.

2. Project construction completion date is expected by December 2026, or sooner.

3. All set monuments shall have the tag of the Professional Land Surveyor (PLS) in charge.

4. Any found ties that do not have a tag shall be tagged by the City’s contracted PLS in charge.

5. Lead, Tack and Tag is an acceptable tie for this project.

6. Replacement centerline monuments shall consist of a 2-inch Bronze (or ferrous-compatible) disc set flush in pavement, with a stamped cross or center punch, detectable by metal detector, or as otherwise directed by the City.

7. The paving contractor is required to protect well monuments. The City’s contracted PLS shall verify that well monuments are undisturbed from the paving contractor’s activities.

8. Corner Records or sketches shall be prepared on the County Surveyor approved form.

9. Proposed fee schedule should include all costs and materials, including but not limited to all necessary traffic controls, preparation and filing fees with the County Surveyor’s Office.

10. Each invoice will be paid after the corresponding Corner Record has been filed with the Office of the County Surveyor or six months after final Corner record submittal to the County Surveyor, whichever comes first.

11. Portion of area 290 (See Attachment B) only needs post-construction since pre-construction Corner Record for this area is already filed with the County Surveyor’s Office.

12. ALL ties should be set outside of the Curb Ramps.

13. Consultant shall be responsible for research and analysis of existing centerline monuments and their associated centerline ties within the streets of the project. Any preliminary information provided by the City as part of this proposal is based on a search for budgeting purposes only and must be verified and researched by the City’s contracted PLS in charge.

14. Consultant shall be responsible for the preservation, recovery, and re-establishment of all survey control monuments impacted by this project. All monument preservation work shall comply with applicable State of California laws, including, but not limited to, the California Professional Land Surveyors Act, the California Public Resources Code, and the California Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG) Rules and Regulations and including the Rules of Professional Conduct.

15.The City reserves the right to verify any monument preservation work, including third-party review, and may request access to all supporting field data, computations, and deliverables for audit purposes.

16.Accuracy: Each centerline monument shall be established or re-established with a horizontal position accuracy of 0.03 feet (1cm) at 95% or better. The stated accuracy is consistent with GNSS Surveying Standards and Specifications, 1.1, published by the California Land Surveyors Association (CLSA) and the California Spatial Reference Center and the CalTrans Survey Manual, Chapter 5, Figure 5-1A Positional Accuracy for a Network Accuracy. The use of RTK or RTN GPS will not achieve the requested accuracies.

Meeting these standards will require the use of post-processed static GPS baselines, integrated with total station observations through a network adjustment.

17.Acceptable survey methods include Total Station Survey System (TSSS) and

Global Navigation Satellite System (GNSS). The procedures, equipment, and specifications shall conform to the Caltrans Surveys Manual: Chapter 7 for Total Station Survey System (TSSS), Chapter 6 for GNSS Survey Specifications, Chapter 5 for Positional Network Accuracy and/or GNSS Surveying Standards and Specifications, 1.1, published by the California Land Surveyors Association (CLSA) and the California Spatial Reference Center (CSRC).

18.Consistent with the Caltrans standards the use of Total Station Survey System

(TSSS) to perform monument recovery and centerline monument preservation is the preferred method for measuring monument to monument for distances under 450 feet. Each monument must be occupied or measured from two locations i.e.

double determined. This is considered best practice for achieving the required horizontal position accuracy, particularly for public right-of-way control monuments and future retracement purposes.

19. Monument Preservation costs will be on a per monument basis, assuming 824 monuments. Of these 824 monuments, 10 will need only one pre-construction corner record (curb ramps) and 814 will need two corner records, one for pre-construction and one for post-construction (CL monuments).
