ST16-01A-CS170406 EXHIBIT “A” SCOPE OF SERVICES PROFESSIONAL ENGINEERING SERVICES AGREEMENT BETWEEN CITY OF COPPELL, TEXAS, AND HALFF ASSOCIATES, INC. S. BELT LINE ROAD FROM NORTH OF I.H. 635 TO SOUTH OF SOUTHWESTERN/DENTON TAP (#####) I.PROJECT DESCRIPTIONS S. Belt Line Road – I.H. 635 to Southwestern/Denton Tap The project involves improvements for the reconstruction of approximately 8,450 linear feet of Belt Line Road, an existing 6-lane concrete roadway, from the northern curb line of the westbound I.H. 635 frontage road to the southern intersection curb radii of Belt Line Road and Southwestern/Denton Tap. The new pavement section will be a 6-lane concrete divided roadway, P6D Principal Arterial (Boulevard) per the City of Coppell Thoroughfare Plan (Coppell 2030) north of Dividend Drive, transition to an 8-lane concrete divided roadway south of Dividend Drive, and will be reconstructed to generally the same lines and grades as the existing roadway. The project also includes renewals of the City’s water and sewer infrastructure within Belt Line’s right-of-way, new traffic signals at Lakeshore Drive and Airline Drive, and modifications to other signals based on construction needs. Other project improvements include new concrete paving for driveway/cross street adjustments, continuous concrete sidewalks, drainage, street lighting, pavement markings, signing, erosion control, traffic control, median landscaping and irrigation. Services provided by the Engineer include preparation of construction documents for the aforementioned improvements; geotechnical investigation and design recommendations for new roadway pavements and miscellaneous structures such as junction structures and monuments; subsurface utility engineering (SUE); and traffic studies of the existing street intersections within the project limits including recommendations for left-turn lane storage lengths and associated intersection improvements.
