Traffic Signal Design. Traffic Signal Modification (Koeblen Road at FM 2977) This task will provide design services for traffic signal modification (adding a widened fourth leg to the intersection) on FM 2977 at Koeblen Road. The basic scope of services for this task of the project will require that HJ Consulting supply electronic copies of the design files for the subject intersection to 500’ on all approaches of the intersection. HJ Consulting shall also provide topographic survey showing all above-ground features and all existing and/or proposed underground utilities to at least 500’ on all intersection approaches. See attached for traffic signal survey requirements.
a) Work with client, TxDOT and Fort Bend County staff to determine the scope of traffic signal modification; Xx. Xxxxxx Xxxxx, P.E., CFM May 5, 2021
b) Conduct site visit to scope the project with client, TxDOT and Fort Bend County staff, as necessary, to document existing conditions and confirm scope of modification;
c) Contact CenterPoint Energy and AT&T for underground utility information at the intersection;
d) Prepare existing conditions diagram;
e) Prepare plan sheet(s), including as needed pedestrian treatments and traffic signal related pavement markings and signing for full traffic signal operation;
f) Prepare applicable notes and general specifications;
g) Prepare index of standard sheets for signal, pavement markings, traffic control and work zone for traffic signal work;
h) Prepare summary of estimate for materials for traffic signal modification;
i) As needed, obtain private utility (CenterPoint Energy and AT&T) signatures to reflect utilities are shown properly on the plans;
j) Prepare cost estimate; and
k) Seal and sign final drawings. Xxxxx Associates reserves the right to negotiate for additional services. Possible additional services may include additional CADD drafting, additional signal or stop warrant studies, other traffic engineering studies, signal design or design tasks not covered in the basic scope above. Other additional services for this project could include, but are not limited to, intersection modifications, including geometric roadway or drainage design and meetings with any agency or group. The estimated schedule and proposed fee, by task, is listed below. Xxxxx Associates, Inc. requests that any additional services be negotiated upon request.
