East Granby, CT
Completion Date: 2005
Total Project Value: NA
Relevant Project Features:
- Prepared the Site Specific Work Plans for the Erection of the Approach and Main Spans
- Performed Slope Stability and Bearing Capacity Analyses
- Performed a utility impacts evaluation based on anticipated crane loads
RT Group, Inc. (RTG) was retained by the Hartland Building and Restoration Company of East Granby, Connecticut to prepare the Site-Specific Work Plans for the erection of Approach Span Nos. 1 through 15, Approach Span Nos. 17 through 22, and Main Span No. 16. The project included sizing the Temporary Erection Towers (TETs); performing slope stability and bearing capacity analyses (for the TETs and timber cribbing beneath the cranes); evaluating girder stresses during lifting; and designing all lifting cables, eyes, hooks, and clamps.
The Approach and Main Span picks weighed about 68,000 and 190,000 pounds, respectively, and were made immediately adjacent to an active AMTRAK line. Several crane types were utilized to make the picks, including a Manitowoc 4100, Manitowoc 2250, and 240-ton hydraulic crane.
At the Main Span, two (2) cranes were utilized, one on each end of the pick. In addition, TETs were utilized to support the Main Span girder during the pick and after setting to make the splice connections.
RTG prepared all of the submittals related to the above work, prepared written responses to RIDOT and AMTRAK comments, and provided periodic consultation during the erection process.
