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. Services
by the Engineer shall also include survey for design and Right-of-Way (ROW)/easement document
preparation.
