CATSKILL — The Greene County Legislature’s Public Works Committee passed two resolutions Monday to accept formal proposals for design and construction inspection services for two bridge projects.
These are for the South Road Bridge over Glen Brook in Cairo and the Hervey Street Bridge over Thorpe Creek in Durham.
The South Road Bridge is a 31-inch, steel multi-girder, single-span Jack Arch bridge with an asphalt-wearing surface. It was built in 1927 and was last rehabilitated in 1998.
The Hervey Street Bridge is a 32-inch, steel multi-girder, single-span bridge with an asphalt-wearing surface and a hand-laminated timber deck, which was last replaced about 19 years ago. The bridge was constructed in 1974.
Replacement of the superstructure, bridge and guiderail design and limited pavement improvements are needed on both spans. The Hervey Street Bridge needs repairs to the substructure, while the South Street Bridge needs a substructure replacement.
Engineering service contracts for both projects will be awarded by Sept. 20. Design and approvals have to be completed by March 16, 2018. The construction contractor’s bid proposals are due by April 3, 2018. The construction contract will be awarded in April 2018. Construction is expected to start in June 2018 and both projects will be completed by October 2018.
Latham-based Clark Patterson Lee Design Professionals is performing the inspection and design services for the Cairo bridge, while the Albany-based Barton and Loguidice, D.P.C., is working on the Durham bridge, Greene County Administrator Shaun Groden said.
“Those things are for the engineering design work,” Groden said. “This is the first step in the bidding process of construction.”
The resolutions have to be passed by the Finance Committee and at the regular monthly legislature meeting next week, Groden said.
“This will be approved in its entirety this month,” Groden said.
The county took proposals from both firms and Groden said they have done work on county projects before. The firms will make a proposal once they’ve finished their site visits to determine what is needed for the project. The information will then be passed to the approved contractor.
“We still go through the process of them [the engineering firms] going out in the field,” Groden said.
When the construction work is awarded to a contractor, inspection contracts are reviewed and certain procedures have to be met, Groden said. If the contract states 3 inches of concrete need to be poured, it cannot be any less than that.
“The contractor will be held to that standard,” Groden said.
The reason two separate firms are working on each of the bridges may come down to price.
“They [the bridges] may be so far separated that there may be no economy of scale,” Groden said.
Each year, the county’s bridges are inspected and an engineering evaluation is done on the steel, bulkhead and embankment of the bridge, Groden said. When bridges age, restrictions are placed on them and some may be weight limits.
“They all have cycles, just like your car,” Groden said. “Eventually, they’ve got to go.”
Many of the county’s bridges have received repairs over the years because of Tropical Storm Irene. Groden said county roads could use more treatment to extend their lifespan.
“Our bridges, in large part, are in better condition than our roads,” Groden said.
Cairo Town Supervisor Daniel Benoit has not been made aware of the bridge project in his town.
“The county didn’t send a letter about it,” Benoit said.
Durham Town Supervisor William Carr Jr. has some inkling on what the bridge project in his town is about and said typically county officials will inform him of the project and how much disruption might be caused by construction.
“They give us a heads up,” Carr said. “It wouldn’t be surprising that we would simply be notified a few days before the work began.”
The roads near the bridge have little traffic and Carr said disruption from construction would be minimal.
“It should be modest in the grand scheme of things,” Carr said. “We have nearly no impact on their project.”
