Asset Management
A systematic process to cost effectively maintain, upgrade and operate an organization’s infrastructure by inventorying assets (roads, bridges, utilities, equipment, facilities) and evaluating specific data (condition, value capacity) in order to make critical infrastructure decisions based on fact rather than assumption.

Innovative Contracting Methods
• Contracts with cost and time components (A+B) versus exclusively low bid contract
• Performance contracting with specific performance requirements
• Design-Build-Finance alternatives being investigated
“ABC” Accelerated Bridge
Construction• Precast bridge
elements
• Building bridges and moving them into place
• Scheduling to reduce customer delays
An Illustration of ABC (Accelerated Bridge Construction)
Parkview Avenue over US-131
Demolition Took Place at Night with Maximum 5 Minute
Freeway Closure
Beam removal was done at night allowing for a maximum of 5 minute lane closures
All Bridge Components were Precast Concrete
Abutment Placement
This abutment segment took 8 minutes to place
Placement of the Pier Caps
Prestressed I-Beams were Placed at Night
The Bridge Deck was Made of Precast Concrete
Panels
48 deck panels were placed in four days
A Hot-Mix Asphalt Wearing Surface was Placed on
the Deck
Waterproof membrane and 1 ½ inch lift of hot mix asphalt (HMA) placed on top of the concrete deck panels
Parkview over US 131
Before After
Self-Propelled Modular Transporters
• Used to move entire bridge spans into place
• Reduces roadway closure time• Less impact to the traveling public
Bridge Preservation
• Epoxy Overlays on bridge decks
• Zinc-based primer paint systems for steel beams
• Acrylic coatings for concrete elements
