Washington Street TAP Exhibit A Page 20 of 23 West Orange, Essex County, NJ Scope of Services - SUE A3080 — Conduct Subsurface Utility Engineering (SUE): The anticipated work to be performed by Taylor Wiseman & Taylor (TWT) includes: A. Mobilization, consisting of: 14. Review available as-built plans and utility record plans. It is assumed that GPI has secured these plans for design purposes and will provide them to TWT. 2. Assess site conditions and plan/layout required traffic control needs for both survey and SUE work. Apply for and obtain a HOP from Essex County for the proposed work. Obtain utility mark-out through NJ One-Call. Review Survey Control Report provided by GPI. Plan and discuss proposed work procedures and schedules with field survey and SUE crew chiefs, with focus on safety B. Perform Quality Level A SUE (Locating/Test Holes) five (5) test holes to locate various utilities as requested, TWT will identify the type and material, measure the size and depth and record the information gathered on a field sketch plan. *** Specific MPT costs are unknown at this point. For estimating purposes one (1) day of local police have been included in our estimate. Oar w Excavated areas will be backfilled as follows, based upon conditions encountered: = In non-paved areas: Backfill with the excavated material and raked to provide a smooth surface grade. = In asphalt paved areas: Backfill with the excavated subsurface material, with asphalt cold patch applied top 6”+ and tamped. * In concrete sidewalk areas: Backfill with the excavated subsurface material, with hand-mixed concrete applied to the top 4” +. Note: Test holes in asphalt and concrete will be sawcut to provide a smooth joint along patch lines C. Recover existing survey control, set supplemental control points as necessary, and survey the locations of the five (5) SUE Test Holes. It is assumed that the previously established survey control identified in the Control Survey Report will be recoverable, and not have to be re-established. D. Compile, review and summarize test hole results. Prepare CADD legal size Test Hole Plan for the five (5) locations providing x,y,z coordinates, a plan view with short ties to the test hole location, and a cross section sketch providing the size and type (material) of subsurface utility, and pertinent elevations (i.e. ground and top/bottom of

a plan view with short ties to the test hole location, and a cross section sketch providing the size and type (material) of subsurface utility, and pertinent elevations (i.e. ground and top/bottom of utility). E. Prepare a CADD file (microstation) the provides the location and number for each test hole, illustrated using the standard test hole CADD cell. A3999 — Administration & Invoicing: Under this Activity, TWT will coordinate/meet with Department in- house design staff as necessary, administer the work, and prepare/submit monthly invoices, with supporting back- up as required, Prepared by: Taylor Wiseman & Taylor 6/17/2025 Page 1 of 2
