RE: |
PW1503 Bob Billings Parkway Corridor Improvements, negotiation of scope and fee for engineering design services. |
Project Description
Bob Billings Parkway between Kasold Drive and K-10 Interchange to the west has been identified as a corridor that needs improvements with the projected additional traffic following the completion of the K-10/Bob Billings Parkway interchange (see attached project map). City staff has gone through an extensive public process with adjacent neighborhoods to identify and prioritize improvements in the corridor. A summary of the process can be found at: http://lawrenceks.org/bbp-improvements.
The scope of the project will include the following:
1.) Mill & Overlay – A mill & overlay of Bob Billings Parkway from Kasold Drive to Wakarusa Drive with full depth patching. Review and design the ability to reconfigure the width of the existing lanes between Kasold Drive and Crossgate Drive to accommodate a center turn lane. Currently the roadway width between Kasold Drive and Crossgate Drive is approximately 52-53 feet wide. In addition, remove the median island to provide a dedicated left turn for the business on the southwest corner of BBP/Kasold.
2.) St. Andrews Drive & Bob Billing Parkway Grading– Review and design of improvements for intersection sight distance with grading improvements to the southwest corner of the intersection.
3.) Eastbound Right Turn Lane/Bus Turn Out – Geometric improvements to provide a right turn lane/bus turn out for eastbound traffic on the west approach of the intersection of Bob Billings Parkway and Kasold Drive. Bob Billings Parkway will need to be widened near the intersection to the south to construct this right turn lane. The existing bus stop and sidewalk would need moved to the south as well. Some right-of-way or sidewalk easement would need to be acquired.
4.) Stone Meadows Drive & Bob Billings Parkway Traffic Signal – Traffic signal shall be installed at the intersection with geometric improvements on Stone Meadow to accommodate a dedicated right turn lane. Upgrade existing sidewalk approaches, ramps and crosswalks to allow for ADA compliance.
5.) Inverness Drive (south) & Bob Billings Parkway Traffic Signal – Traffic signal shall be installed at the intersection with geometric improvements on the north and south approaches to accommodate a dedicated left turn lane. Upgrade existing sidewalk approaches, ramps and crosswalks to allow for ADA compliance.
6.) Bob White Drive & Bob Billings Parkway Traffic Signal – Traffic signal shall be installed at the intersection. Upgrade existing sidewalk approaches, ramps and crosswalks to allow for ADA compliance.
7.) Sidewalk Gap (Monterey Way to Inverness Drive) – Install sidewalk on the south side of Bob Billings Parkway from Monterey Way to Inverness Drive. Minimize conflicts to landscaping and utilities with use of retaining walk where needed.
Consultant Selection Process
A 5-member selection committee reviewed the Qualification Statements and rated each firm’s proposals on criteria listed below on a 0-10 scale, 10 being the best. Scores were totaled and firms were ranked by best score in order to select the design consultant. Consultants who submitted proposals included (Bartlett & West, BG Consultants, CFS Engineers, and Landplan Inc.). The committee members were: Chuck Soules, Public Works Director; David Cronin, City Engineer; Zach Baker, Project Engineer; Nicholas Voss, Project Engineer; and Steven Lashley, Project Engineer.
Firms were evaluated on the following criteria:
|
1. |
Commitment of staff, equipment and facilities |
|
2. |
Ability to perform the desired services within the time prescribed |
|
3. |
Past performance of firm |
|
4. |
Staff’s training schools attendance |
|
5. |
Previous experience with similar work |
|
6. |
Work commitment which could limit performance |
|
7. |
Accessibility of firm’s office |
|
8. |
Firm’s familiarity with project area |
|
9. |
Firm’s knowledge of project procedures |
|
10. |
Firm’s consideration of project problems/issues |
|
11. |
Thoroughness of presentation |
|
12. |
Communication issues |
|
13. |
Ability to work with public |
|
14. |
Professionalism, comfort level with firm |
|
15. |
Overhead costs |
Based on a thorough evaluation using the above mentioned criteria, the selection committee is recommending that the city negotiate an Engineering Services Agreement with BG Consultants.
Project Cost / Funding
The original proposed estimated design and construction cost was $2,250,000. The choice of using the alternate design of signal installation at the Bob White intersection with Bob Billings will increase that total construction cost. Currently $1,650,000 from infrastructure sales tax and $600,000 in general obligation bonds is budgeted.
Project Schedule
Scope and Fee Negotiations: January 2016
Engineering Design and Construction Plans: Winter/Spring 2016
