Project Location: General Cargo Pier; Chiriquí Grande, Panama
Client: Dillon Construction, Inc.; Panama
Dates: January-1996 to March-1996

The City of Austin is extending the existing South first Street for a total length of about 10,000 ft south of its current termination. The roadway covers a total width of 120 ft, carrying four lanes of traffic, two bike lanes, two pedestrian sidewalks, and a median of 20-ft width. Two bridges of about 500 ft and 400 ft lengths are necessary for the crossings of the new roadway over Slaughter Creek and Nichols Branch Creek. The roadway crossings are designed with twin-bridge structures over the creek, each bridge with a width of 39 ft, each carrying two lanes of traffic, a bike lane, and a pedestrian sidewalk.

Reaction beams with a recoverable system of high-strength reaction bars were designed for the axial load test of two 42 in. o.d. steel piles at the site of a proposed general cargo pier in the southern shore of the Laguna de Chiriquí, in the Atlantic Coast of Panama. The reaction beams were designed for maximum axial loads of 1,000 Tons on 29-ft spans. The complete reaction structure, including 240 ft length of 42-in. o.d. steel casings for the reaction shafts and 2,500-ft length of dywidag bars were designed to be recoverable.
