This project is the reconstruction of the existing four-lane, each-way coupler streets of Shepherd and Durham, major thoroughfare streets, and selected cross streets from 15th Street to IH-610 (Phase I) and from IH-10 to 15th (Phase II). As a subconsultant, A+ Services provided technical support services to Jones & Carter (Prime) for the related water/wastewater improvements including need/condition assessment of lift stations for diversion, alignment evaluation, and reconnections of utilities. A+ Services provided the following engineering services:

• Assessment and route evaluation of existing sanitary systems, for the future abandonment of the lift stations through a flow diversion.
• Diversion and abandonment (as needed) of the existing sanitary sewer system from Shepherd LS and Durham LS through proposed 24” sanitary, approximately 1500 LF.
• Micro-tunneled of proposed 36” sanitary sewer, approximately 3,300 LF, to connect to an existing 84” trunk sewer line on 12th Street.
• Replacement, upgrade, and reconnection (as needed) of the existing 6” to 36” sanitary sewer, approximately 48,000 LF, and related appurtenances within the project area.
• Aerial crossing structural retrofit design for the replacement of a 12” waterline, approximately 200 LF, attached under the existing Shepherd bridge across the White Oak bayou.
• Replacement, upgrade, and reconnection (as needed) of the existing 6” to 24” waterlines, approximately 33,000 LF, and related appurtenances within the project area.
• Development of project-specific traffic control plans including the construction phasing plan and support of the construction schedule
• Support for constructability consideration as related to the construction phasing plan.
• Development of plans, specifications, and estimates for the proposed water/wastewater improvements.
