Task II.	Preliminary Design

1.01	Data Collection

A.	Attend pre-design meeting.

B.	Develop design criteria for the project; prepare design memorandum.

C.	Develop detailed design schedule including the following due dates:

1.	Notice to Proceed

2.	Preliminary plans due

3.	City Review Complete

4.	90% Plans Due

5.	City Review Complete

6.	Final Plans Due

D.	Field data collection

1.	Field surveys (spot-checks of information provided by the City, including lane widths, sidewalk locations, existing pavement markings, and box locations in areas near future poles). Review the condition and location of existing signal poles and service boxes. The City shall provide the bolt pattern for the mast-arm connection located on the existing signals posts located in the median on Metcalf Avenue.

2.	Contact utility companies or one call center as appropriate for field marking of utility locations.

E.	Coordinate power location with Kansas City Power & Light Company. Copy the City of Overland Park with all correspondence to KCP&L.

F.	Obtain from the City current daily traffic volumes and peak period turning movement counts.

G.	Determine the required lane configurations, signal phasing, and traffic control for the project. Examine the existing lane geometrics along the project and determine traffic control and/or geometric improvement recommendations as might be warranted. (No level of service analysis is included.) Meet with the City to review the recommendations.

H.	Coordinate design of the traffic signals with the existing and proposed development in the surrounding area.

1.02	Prepare base map at a scale of 1 inch = 20 feet.

1.03	Develop preliminary plans (standard details and sheet elements will be provided electronically by the City):

A.	Cover sheet

B.	Plan sheets:

1.	Traffic signal layout including location of all proposed poles, loop detectors and detection zones, service, junction and fiber optic boxes, and the signal controller.

2.	Proposed signal phasing.

3.	All wiring details and diagrams.

C.	Quantity sheets

D.	Detail sheets (using standard details provided by the City).

E.	Intersection lighting design – incorporation of intersection lighting onto traffic signal poles. (No detailed lighting analysis is included.)

F.	Preliminary traffic control (using standard details provided by the City).

G.	Preliminary pavement marking and signing.

Prepare detailed wheelchair ramp design layout sheets.

1.	Consultant shall assume that the ADA ramps recently constructed with Truncated domes on the east side of Metcalf Avenue at 137th and 138th Street meet current standards and do not need to be modified.

The consultant shall verify that the existing wheelchair ramps on the west leg of 137th Street meet current design standards and upgrade to such as required. If the current grades for the ramps are adequate then only truncated domes “adhesive type” will be added to the current ramps.
