• 10 new bridges
• 200,000 cubic meters of embankment
• 8,000 square meters of MSE retaining walls

Taxiway B East, Portland International Airport
Owner: Port of Portland

This airport improvement project met stringent FAA specifications and included:

• 4,000 lineal feet of concrete taxiway, 75 feet wide, 18 inches deep

Phillip Harris Bridge
Owner: Washington County

• 40 feet wide with 24 precast, prestressed, 60 inch, bulb-T concrete beams (BT60)
• 2,400 cubic yards of poured-in-place concrete used to complete the balance of the new larger structure
• 4,350 psi high performance concrete mix design in the bridge deck
• 13,900 square feet of concrete block walls in five locations to form the approaches to the bridge. This type of wall was used to widen the road within a limited right-of-way and to protect environmentally sensitive wetland areas
• Architectural concrete elements were added to concrete bollards on the ends of the bridge in raised symbols of plowed fields, corn, grapes and strawberries

• 24” drilled piling on the west bent
• 726 cwt of driven HP 14x89 and 14x117 piling on the east
• 49 tons of black and epoxy coated rebar
• Approximately 860 CY of structural concrete and 580 CY of HPC 5000 deck concrete
• A total of 8 bulb-T girders set in 2 stages
• A single-span 84-inch bulb-T girder - previously set the longest girder fabricated in Oregon at 163 feet
• Each beam weighed 132,500 pounds
• Incorporates a rock MSE wall at the east abutment

Isthmus Slough
Owner: Coos County

• Project finished a year ahead of contract schedule
• The new bridge structure is a four span, 700 foot long by 34 foot wide cast in place post-tensioned box girder
• Required the placement of over 1,200 cubic yards of concrete on false work. Substructure construction required over 10,000-ft of 24” diameter driven pipe piles and 4,000 cubic yards of concrete
• Three large cofferdams were used to construct the in-water footings, which are well below the river bottom
• The work was accessed from a 300-foot long work bridge and floating barge
