Downtown Pavement Maintenance Project

2008 Mill & Overlay

Meeting with Downtown Lawrence Inc.

7:30 AM, April 9, 2008

Project - Mill & Overlay

· Massachusetts – 6^th to North Park

· Kentucky – 6^th to 12^th

· 7th St – Vermont to New York

· Alternate Section (if funds are available)- Kentucky- 12^th to 19^th

General Goals for Paving Projects

· Most economical process possible

· Best finished product possible (smooth, min. no. joints)

· Minimize construction schedule

· Minimize impacts on traffic and adjacent properties

Potential Implications of Increased Restrictions

· Higher costs with lost efficiency

· Lower quality of finished product if done piecemeal (rougher, more joints)

· Longer construction schedule

· May or may not minimize impacts on traffic and adjacent properties

· Lack of interest by contractors

Proposed Approach for Massachusetts

· Milling of entire length can occur under traffic

o Some obstructions from parked cars could slow down progress

· Close 2-3 block segments at a time for patching and paving

o Cross streets will be closed except 9^th – no work through the 9^th St intersection i.e. if 6^th to 8^th or 9^th is closed, then 7^th and/or 8^th will be closed at each edge of Mass

o Perform all patching and then paving

o Reopen segment

· Move to next 2-3 block segment

· Concrete collars around manholes and water valves in pavement will be done after paving is complete. Contractor will provide traffic control to minimize traffic impacts.

· Similar approach is suggested for paving 7^th St and Kentucky

· No closure of Kentucky or 7^th St. while any segment of Mass is closed. Some work may be allowed on Kentucky and 7^th as long as traffic is not significantly impeded

Approximate Time Required

· Milling & cleanup – 2-3 days

· Closure for each segment – 3-4 days depending on amount of patching required

· Total Time on Mass (if closures allowed) - 12-15 days

· Contractor will be required to work continuously on Mass until complete

(Remember – Construction is weather dependent. We will try to avoid starting work when weather forecasts indicate completion may delayed for several days)

Project Schedule Assumptions/Questions

· Work on Mass must be completed before Sidewalk Sale (July 17)

· Will contractor be permitted to work on weekends- Sat and/or Sun?

· Are there other scheduled events in the downtown area that need to be considered?

· Need to have contract awarded and ready to start by June 1 to provide adequate “contingency” in the schedule for weather impacts and still meet July 17 date
