Multi-modal improvements


Planning and Schematic Design› Project Data

Posted speed: 25 mph North University ADT: 7200 Pedestrian crossing peak hour volume: 1000 Pedestrian peak hour volume along N. University: 700 Bus volume along N. University: Approx 75 per hour

› Scope of Work Project budget: $4,000,000 Maximize project goals Accelerated schedule


Planning and Schematic Design› Options explored & studied

Bus storage area needed Pedestrian travel patterns Pedestrian capacity analysis and bus loading evaluation Shelter capacity analysis and expansion considerations Traffic and turning movement study Roadway improvement options & recommendations Sustainable design studies & recommendations Bicycle lane configuration and location


Planning and Schematic Design› Options explored & studied (Continued)

Lighting options & recommendations Options to enhance median area Wayfinding opportunities Options for dynamic signs and kiosks Construction staging and temporary bus stop options Options to reduce scope to meet budget Evaluation of bidding project (lump sum versus unit

price) Project justification report for University Regents


Detailed Design› Schedule:

March 2009 – Notice to proceed August 2009 – Schematic design complete January 2010 – Final plans complete

› Infrastructure Improvements Watermain replacement Storm sewer improvements Road reconstruction


Detailed Design› Multimodal improvements

Consolidate pedestrian crossings Provide bicycle lanes Improve University plaza areas Consolidate bus stops (AATA and University) Provide ADA Accessible site Install bicycle racks to meet demand Construct bus stop shelters on both sides Wayfinding (static & dynamic signs, kiosks)


Detailed Design› Custom Bus Stop Shelters

Drilled piers & steel structure Glass enclosures Translucent panel roof

› Maintenance of Traffic & Construction Staging Full road closure Coordination with City and University Work not to start until after school (May) Road to be open during Ann Arbor Art Fair (July) Work to be complete prior to school start (September)


Detailed Design – Layout Plan


Construction› Aggressive schedule

Pre-purchased steel Infrastructure improvements & site work Structural elements Roof panels Amenities (bike racks, wayfinding, pavers, etc.)

› Site constraints & requirements Small project area Road open by Art Fair Maintain ingress/egress to University buildings


Construction› Challenges

Unanticipated utilities Material changes Delays

› Solutions Fast-track decisions & design changes Contract negotiations Overtime and additional manpower
