Rutgers-BEAST_Civil-Engineering-MagThis month’s edition of Civil Engineering Magazine highlights the world’s first accelerated testing facility for full-scale bridges: the Bridge Evaluation and Accelerated Structural Testing Lab (BEAST).

The BEAST was designed by a team of Rutgers engineers and other bridge experts, with assistance from Applied Research Associates, Inc. (ARA). ARA constructed some of the massive components of the BEAST, especially a set of parallel steel I beams 120 ft long by 7 ft deep, at its plant in Randolph, VT. DuBois & King supported ARA with civil/site design, permitting, and structural engineering services including design of concrete abutments and foundation design for the environmental simulation enclosure. Site engineering included utility relocations, coordination of electrical design for 1200 KVA and as-built survey of the rail system.

Ryegate Design-Build ProjectRyegate Design-Build ProjectRyegate Design-Build ProjectDuBois & King is the Lead Design Engineer for a $15.2M culvert replacement design-build project in Ryegate, VT. Deteriorated undersized culverts have contributed to flooding of US Route 5 and the backwater jeopardized the integrity of the roadway and rail embankments. The design-build team of DuBois & King and Engineers Construction (ECI) are working with the Vermont Agency of Transportation to construct two buried 32-ft-wide by 16-ft-high, cast-in-place, reinforced concrete arch culverts beneath the roadway and rail line. The new culverts are 144 ft and 128 ft in length, and will increase the hydraulic capacity by 25 times the existing capacity.

Excavations up to 70-feet deep have been completed and concrete is being poured. All of the footings have been completed and ECI is now forming and pouring the cast-in-place concrete arches. Concrete pours are expected to continue throughout the winter. The contractor is utilizing special cold-weather procedures, including heating and blanketing the fresh concrete to protect it from freezing as it cures.

Waitsfield-Covered-Bridge_CompleteWaitsfield-Covered-Bridge_CompleteWaitsfield-Covered-Bridge_CompleteD&K designed repairs for the Waitsfield Covered Bridge which have been completed. Improvements included:

  • removal of the former sidewalk and replacement with a new self-supporting sidewalk on widened abutments
  • replacement of rotting floor beams
  • replacement of the timber wearing deck
  • repairs to the abutments
  • repairs to the roof
  • improvements to approach railings and signing

The project also included the complete reconstruction of Bridge Street between Main Street and the Covered Bridge. This work included:

  • new pavement and subbase
  • replacement of the sidewalks
  • new curbing
  • new drainage pipes
  • the installation of decorative benches, bricks, and street lights

With the widening of the abutments on the downstream side of the bridge, the Town of Waitsfield is going to be installing decorative railings so the public can use the areas behind the wingwalls as scenic overlooks.

Wil's PumpkinWil's PumpkinDuBois & King’s Wil Horton took first place in the 2015 Vermont Giant Pumpkin Growers Weigh-off. Wil hauled his 1438-pound pumpkin from his patch in Springfield to Colchester, Vermont for the September 26th event. Wil’s green thumb also extends to field pumpkins and long gourds and took first place with his 101-pound field pumpkin and his 110” long gourd.

Wil also made it to events in Massachusetts and New Hampshire this year. Wil ranked 11th in the New England Pumpkin Growers Association event at the Topsfield Fair in Topsfield, Massachusetts, with his 1278-pound pumpkin. In late August, his 748-pound entry won second place at the Champlain Valley Fair in Essex Junction, Vermont. Wil’s 1278-pound pumpkin won second place at the Giant Pumpkin Weigh-off in Goffstown, New Hampshire. Wil donated the pumpkin to the Goffstown Mainstreet Program to be turned into a boat for the Pumpkin Regatta. The following link shows the proud grower with his first place pumpkin, field pumpkin and long gourd. Wil is an electrical engineer who works out of the firm’s Springfield office. Congratulations Wil!

On October 14, Rutgers Center for Advanced Infrastructure and Transportation (CAIT) in Piscataway, New Jersey, unveiled the Bridge Evaluation and Accelerated Structural Testing Lab (BEAST), the world’s first accelerated testing facility for full-scale bridges.

Applied Research Associates, Inc, (ARA), an international research and engineering company, designed and built the core of testing facility in their Randolph, Vermont location. DuBois & King supported ARA with civil/site design, permitting, and structural engineering services including design of concrete abutments and foundation design for the environmental simulation enclosure. Site engineering included utility relocations, coordination of electrical design for 1200 KVA and as-built survey of the rail system.

According to the CAIT website, the BEAST will be used to “quantitatively measure stresses and deterioration caused by extreme traffic and environmental loading on full-scale bridge systems—and do so in an extremely compressed time frame. Data from the BEAST will allow us to project future performance and longevity of bridge materials and components. The BEAST subjects bridge specimens to rapid-cycling environmental changes and extreme traffic loading to induce and speed up deterioration as much as 30 times, making it possible to simulate 15 to 20 years of wear-and-tear in just a few months.”

“We anticipate being able to validate how various bridge designs, construction materials, and elements can be expected to perform decades from now and give bridge owners empirical evidence to support decision making,” says CAIT research engineering project manager Andrés Roda.
