DDOT requires preparing design plans for the installation or modification of the Accessible Pedestrian Signals (APS) devices. Work under this scope would include the following but not limited to:

C.3.3.1 Maintain and Update the DDOT APS Framework

DDOT is currently developing a ranking and prioritization framework for deployment of APS devices at all signalized intersections in the District. The selected Consultant shall continually update and maintain the District’s APS Implementation Framework. Key tasks shall include maintaining and updating the master APS inventory and evaluation spreadsheet; incorporating newly available data, completed installations, and changes to intersection conditions; and removing locations affected by construction or other programmed improvements. The Consultant shall periodically re-evaluate intersections for APS compliance using the established evaluation framework and update complexity classifications (low, medium, and high) as conditions change. The prioritization and ranking methodology shall be reviewed and adjusted as needed to reflect updated inputs such as pedestrian volumes, accessibility generators, High-Injury Network status, operational characteristics, stakeholder requests, and DDOT policy direction. Updated rankings, deployment matrices, schedules, and supporting graphics shall be prepared in electronic format and coordinated with DDOT to support informed decision-making and annual APS programming and implementation.

C.3.3.2 Prepare Design Plans and Plans, Specifications and Estimates (PS&E)

The Consultant shall prepare design plans, including but not limited to signal drawings (S-Drawings), design work orders, traffic sequence of operations (TS) drawings, dial sheets, PS&E packages, etc. to support the field implementation of APS devices.

DDOT anticipates following three (3) major categories of the APS designs:

C.3.3.2.1 Simple Retrofit (Low Complexity) APS designs

Revise or modify the existing S-Drawings or develop new aerial-based work order designs for the installation of APS for Low Complexity locations. These locations would presumably require minimal design details as only existing field signal equipment, other than the proposed APS devices, will be required. The modified/revised existing S-Drawing or work order design will show the applicable existing equipment as well as proposed APS and necessary wiring required for the field implementation. Revised TS drawings and dial sheets will be developed for each location to indicate the addition of the APS device.

C.3.3.2.2 Minor Retrofit (Medium Complexity) APS designs Revise or modify the existing S-Drawings, new S-Drawings, or develop new aerial-based work order designs for the installation of APS for Medium Complexity locations. Work order designs may be possible where the proposed new field signal equipment (e.g. poles) can be placed with minimal constraints (e.g. underground, surface level, overhead, or right-of-way conflicts). Depending on the condition of the existing S-Drawing or the required placement of new field signal equipment (e.g. poles), a new S-Drawing may be required for Medium Complexity locations though most of the equipment on the new S-Drawing would be existing equipment to remain. Utility record plats and field utility information will need to be collected for most Medium Complexity locations. When prepared for Medium Complexity locations, communications plans will not be included since the communications design will not be modified. The modified/revised existing S-Drawing, new S- Drawing, or work order design will show all applicable existing and proposed signal equipment as well as proposed APS and necessary wiring required for the field implementation. Revised TS drawings and dial sheets will be developed for each location to indicate addition of APS device.

C.3.3.2.3 Major Retrofit/Rebuild (High Complexity) APS designs Prepare new S-Drawings for High Complexity locations to include full reconstruction of all signal equipment including poles, manholes, conduits, mast arms, lighting, vehicle and pedestrian signal heads, APS pushbuttons and signage, traffic cabinet and controller, and connections for communications equipment. DDOT anticipates following tasks for preparing new S-Drawings:

• Obtain existing utility record drawings.

• Conduct utility record search from various utility companies, including but not limited to DC Water, PEPCO, Comcast, Verizon, and local cable service vendors, such as Comcast, AT&T, etc. Further, coordinate with Miss Utility for marking utilities in the field.

• Prepare Base-Mapping at a scale of 1” = 20” showing existing site features, geometrics, markings, ramps, utilities, signing, lighting and right-of-way lines based on the Utility Record Research and other available references.

• Perform Field Review including tape and wheel survey to confirm base mapping. During this process, we will review the existing pedestrian features for ADA compliance. Existing utilities that can be identified in the field such as manholes will be located.

• Prepare ultimate Signal Plans (S-Drawings) and Wiring Sheets at a scale of 1” = 20” to include all known existing and proposed underground appurtenances (shown on Utility Plan), intersection curb lines (both existing and proposed) and geometry, curb ramps, streetlights, signing and markings consistent with the modified signal operation for a total of (2) sheets.

Temporary signal plans may be required at some locations.

C.3.3.2.3.1 The Consultant shall submit Project Deliverables for major signal retrofit/rebuild projects that conform to the following requirements:

• Submit Utility Plan at a scale of 1" = 20'.

• Submit Communication Plans (scale 1" = 50') showing required changes to the traffic signal system communications network interconnected with the existing signal system. Need to prepare up to three (3) sheets.

• Submit ADA Ramp Design Detail Sheet at a scale of 1"=5' showing existing and proposed curb lines, ramp dimensions and slopes. One (1) Sheet will be required.

• Submit photometric analysis of proposed intersection design.

• Submit Sequence of Operation (TS) Drawings to detail the operation of the signal in Phase-Based format consistent with software requirements of the intersection controller and the central traffic signal system.

• Submit Dial Sheet in OMNI format to show the amount of time allocated to phases, clearance intervals, the offset relationship between adjacent signalized intersections and the time-of-day coordination.

• Submit Construction Cost Estimate (based on DDOT's latest price index) with an itemized list in the Excel format provided by DDOT.

C.3.4 Traffic Signal System Modernization

As part of its mission to improve traffic safety and mobility, DDOT is replacing the following: (i) existing 1,601 signal controllers (model 170 & 2070) with FLeX II ATCs, and, (ii) existing QuicNet traffic signal control system (TSCS) with the MyCity central system. Below is the summary:

• TSCS Procurement – DDOT has contracted with Swarco/McCain to provide installation, operations and maintenance support for the new MyCity TSCS.

• Signal System Manager – DDOT will procure services of Signal System Manager for developing CCPs, supervising test activities performed by the EC, and, supervising installation of new ATCs at all signalized intersections in the District.

• Construction Phase – DDOT will procure the services of Electrical Contractor (EC) to furnish and install new ATCs under two (2) separate phases – Phase 1 (1,580 “Typical” intersections) and Phase 2 (10 “Complex” intersections).
