LocationLocation


Alexander Hamilton Bridge HistoryAlexander Hamilton Bridge HistoryA new eight-lane arch span was

proposed - the Alexander Hamilton Bridge – to connect the Trans-Manhattan and Cross-Bronx

Expressways.

Currently, estimated traffic over the Hamilton Bridge is over 188,000 vehicles

per day.

The Alexander Hamilton Bridge has not undergone

major repair since it opened on January 15, 1963.

In 1955, Robert Moses determined that the 181st Street Bridge would not be able

handle the anticipated traffic demands from the proposed lower level of the

George Washington Bridge.

Scope/Elements of WorkScope/Elements of Work


• Remove and replace existing deck• Fill in median framing• Widen deck by 11’ each side• Continuity splices in approach spans – make 2 span

continuous• Some floorbeam and stringer replacement• Eliminate some deck joints – reduce number of deck joints by

50% • Construct new cap beams at piers• Replace bearings • Repair substructure concrete• Retrofit substructure to meet current seismic requirements • Paint steel superstructure • Replace drainage, overhead sign structures & lighting

– Keeping schedule relevant– Able to use schedule– Tracking schedule impacts– Modeling mitigation – Modeling acceleration


Weekly Update ProcessWeekly Update Process• Contractor physically updates

schedule with progress and prepares PDF prints for schedule meeting:– Weekly Update Critical Path– Weekly Update Look Ahead (3-4 months)– PDF of any proposed changes

• Also discuss additional changes that need to be made to schedule for monthly update


Weekly Update Schedule Weekly Update Schedule MeetingMeeting

• Status of schedule for the week• Why did milestone dates move?• Who is responsible?• Key issues

– Important submittals and how they are or can affect schedule

– Construction Issues and how they are or can affect schedule



• Driving Critical Path activities– Do they make sense?– Are we working on them every day?

• Look ahead– Review low float or negative float activities

• Why?• Can the schedule be adjusted to fix float?

• Review upcoming changes– Direct Contractor to adjust schedule based on

approved changes– Allow Contractor to input changes – subject to

review with monthly submission



• Who attends?– NYSDOT Scheduler– Resident Engineer– Engineer in Charge– Area Supervisor*– Submittal Coordinator*– On-site Design Coordinator*– Contractor’s Scheduler– Contractor’s Engineering Management** Available on an as-need basis

AHB – Contractor Baseline TimelineAHB – Contractor Baseline Timeline


• Split up Stage 2 – start Stage 3 early

• Start Stage 6 west approach work early• Speedy review of critical submittals• Early opening of Temporary Bridge 7

Mitigation EffortsMitigation Efforts


• Eliminate Stage 3 Phase 2• Acceleration program• Used schedule to show how acceleration could

mitigate impacts and move bridge decks for remaining stages into preferred construction season

Additional Mitigation EffortsAdditional Mitigation Efforts


Lessons LearnedLessons Learned• Buy-in by Project Team and Management is

key• Provide Design Schedule/Template to

Contractor in enterprise system• Schedule Specification• Minimum bid price for scheduling• If you maintain the integrity of the schedule

you can actually use it to manage the project
