The Greater New Orleans Expressway Commission (GNOEC) sought to improve the safety of the 23.83 mile Lake Pontchartrain Causeway Bridges by adding shoulders and emergency pullover areas on both spans.
The GNOEC chose a Construction Management at Risk (CMAR) delivery method for a solution to meet their stated goals of:
- Increased emergency stopping areas
- Cost effective solution
- Least Impact to Commuters
Boh Bros.’ experience in the CMAR process facilitated concurrent design and construction of twelve (12) – 1,008-foot-long pullover lanes comprised of precast components which were fabricated offsite and subsequently transported and installed from the water, thereby drastically minimizing work zones on the bridge and traffic impacts.
Twelve (12) – 1,008-foot-long by 16-foot-wide safety shoulders, comprised of:
- 192 – 54” diameter Precast concrete spun cast cylinder piles, varying from 54’ – 104’ long
- 192 – Precast concrete caps, varying from 11’-15’ in length, 4.67’ wide, 3.58’ depth
- 216 – Type III Girders, 53’–8” long
- 144 – Type IV Girders, 83’-11” long
- 180 – Precast deck sections complete with barrier rails
Avondale Marine Project
Boh Bros. assisted Avondale Marine in rebuilding Dock No. 2 so that Host can use the dock’s existing pile–supported ship ways to construct a suspended roadway. Once operational, trucks will be able to carry heavy loads from dock to land, and vice versa, as the roadway will have a 100-ton capacity.
The Florida Avenue Project
The Florida Avenue Canal improvement project, as part of the Southeast Louisiana Urban Flood Damage Reduction Program (SELA), consists of widening the existing concrete flume and box culvert sections of the Florida Avenue Canal from Drainage Pump Station 19 to Drainage Pump Station D. Boh Bros.
Ft. Lauderdale-Hollywood International Airport
Boh Bros. traveled to Ft. Lauderdale, Florida to work as the paving contractor on Ft. Lauderdale-Hollywood International Airport’s $64 million rehabilitation effort. Boh Bros.’ scope included nearly $16 million in concrete paving and involved both the replacement of the North Runway and sections of Taxiway B.
