]]> Last week, PC completed the replacement of the rubber dam bladder – the largest of its kind in the United States – at the Highgate Dam in Vermont. The original bladder, which was installed in 1992 by PC Construction, had reached the end of its lifespan and when time came for replacement, the Village of Swanton brought PC back to get the job done.

The new inflatable bladder, which was shipped from China, is 267 feet long and 57 feet wide, weighing a total of 47 tons. During installation, the bladder had to line up with the 576 existing anchor bolts on the dam’s concrete surface. To ensure precise placement, the bladder was laid out flat to allow PC Construction to work with a surveyor to punch holes along the bladder’s edge. It was then folded up for transport to the dam for final preparations.

Work began on July 1 with the construction of an access road to the river. Once the road was in place, crews removed the old bladder, donating the salvaged material to local farmers to be used as bedding under livestock.

After the new bladder was delivered to the site on July 29, it was unfolded and installed, bolt-by-bolt, until it was securely in place. PC completed the installation on August 13 and officially finished the project on August 24 after several rounds of testing.

Project partners included G.W. Tatro, CCS Crane Service, Barrett Trucking, HTE Engineering, H.L. Turner, and most importantly the Village of Swanton. They were an outstanding owner, partnering with PC at every opportunity.

]]> Over the course of three days, PC Construction worked with subcontractor G.W. Tatro to place an 83-foot stream crossing section of new 6 ½-foot-diameter penstock for Green Mountain Power. The penstock carries water from the Glen Dam to the hydroelectric station located on Route 7 in Rutland, Vermont.

PC Construction’s Special Projects Group is serving as the construction manager for the project and is also self-performing the associated concrete work. The project includes the replacement of approximately 1,700 lineal feet of existing 78-inch I.D. riveted steel penstock with new I.D. spiral welded steel penstock, as well as the removal and replacement of the existing concrete foundations. The section of pipe shown in the photo was especially challenging because the concrete piers are located on either side of an existing stream that could not be altered or disturbed. PC Construction and G.W. Tatro developed a plan to pre-fabricate and install the complete span, the longest of this type we’ve ever installed, in a way that it could be completed without working in the stream.

Work began in early August and substantial completion is expected by late November.
