Version 6-8-2017 21 v.Once the field information is completed and checked by the field crew supervisor, the SUE Field Supervisor will perform a quality control (QC) check of the project by cross checking the proposed scope of work to verify that all designating is complete. The test hole locations will be surveyed and incorporated into the topographic base map. b.Quality Level A: Air/Vacuum Subsurface Utility Locating performed as follows: i.Call the appropriate Indiana Plant Protection prior to digging any test holes. ii.The number of test holes will be determined during design. iii.Excavate test hole to expose the selected utility at a specific point indicated by the CONSULTANT. iv.Excavate the test hole by vacuum excavation or hand digging in order to prevent damage to wrappings, coatings, or other protective coverings. v.Minimum excavation assumed to be 8”x 8” (64 square inches). vi.Follow ASCE Standards for Collection and Depiction of Existing Subsurface Utility Data: •The horizontal and vertical location of the top of the utility referenced to the project survey datum. •The elevation of the existing grade over the utility at a test hole referenced to the project survey datum. •The outside diameter of the utility and configuration of non-encased, multi-conduit systems. •Type of utility (e.g., fiber optic, gas, water, sewer, telephone, etc.). •The utility structure’s material composition, when reasonably ascertainable. •The paving thickness and type, where applicable. •An above ground marker (i.e., PK nail or 5/8” capped rebar) will be placed above the centerline of the utility; to be used for horizontal and vertical reference information. •Such other pertinent information as is reasonably ascertainable from each hole site. vii.Back fill and compact test holes in accordance with LPA standards for concrete patching. Restore all locate holes to the condition they were in before, or better. Replace asphalt/concrete with equal or greater thickness as needed to repair roadway. Provide cleanup of work site to equal or better condition before excavation. viii.Provide reference points for surveyor. ix.Once the field work is complete, the CONSULTANT shall review the data and develop a conflict resolution plan to avoid existing utilities where feasible. E.Roadway Design Plans The CONSULTANT shall provide engineering and design services to prepare plans, calculations, cost estimates, and other submittal documents in accordance with requirements outlined in the INDOT LPA Process Guidance Document for Local Federal Aid Projects, dated March 2022 and IDM. The project limits are along Bendix Drive from just south of the intersection with Voorde Drive to approximately 480’ north of the centerline of Lathrop Street, for a length of approximately 4,100 feet. The CONSULTANT shall prepare roadway plans in accordance with the following: 1.Reconstruct Bendix Drive, along the current alignment, within the limits described above to be a 3- lane curbed roadway with an 8-foot multi-use path on the east side of the corridor. 2.Lathrop Street and Voorde Drive approaches to Bendix Drive will only be reconstructed as far back as necessary to transition from their existing configuration to the proposed Bendix Drive layout. 3.The CONSULTANT shall develop Maintenance of Traffic Plans along Bendix Drive based on a one-way detour. It is anticipated that southbound traffic flow will be maintained through the project limits during construction. Full road closure may also be considered as a possible alternative to reduce costs and construction schedule. Also, a temporary closure may be required for installation of the proposed storm sewer and water main under the NICTD railroad track. The CONSULTANT shall coordinate the maintenance of traffic plans and detour route with the LPA.
