The Region

Superstructure work continues to advance toward Vermont as the contractor continues formwork for overhangs. Shear stud placement and grouting have been completed and rebar installation will continue in earnest beginning on Monday, July 8th after the holiday. Dewatering and treatment tanks that have been awaiting removal have been tentatively scheduled to be cleaned and taken away sometime next week.

Work continues to progress toward the Vermont abutment on the remaining overhang formwork, placing shear studs into girders, grouting deck panels, and placing rebar. Grouting of deck panels in Vermont will take place on Monday, July 1st, with the concrete delivered to a pump truck located beneath the bridge in the Barrows & Fisher’s property.

Increased construction traffic is anticipated adjacent to the work zone on Vermont Route 142 while the large crane is disassembled. Motorists should remain vigilant.

Due to current work on New Hampshire Route 119 associated with the project, the eastbound lane shift on NH 119 shortly after traveling over the twin bridges remains active. Signs and barrels are in place to assist motorists through the work zone.

Work has continued on the cap for Pier 1 with the rebar being flown into place and tied atop the stem. Form work for the cap will be completed, bearing seats fully constructed, detail work finished, and everything fully adjusted to match plan location and elevation prior to the scheduled concrete placement next Tuesday.

Additional crews may begin work on the drainage installation required in the Barrows and Fisher yard late next week.

Crews have stripped all forms for the Pier 1 footing and stem. The footing has now been backfilled with clean stone and the cofferdam sheets have been pulled. Work has begun on the cap for Pier 1 and forms are being placed. Next Tuesday, the cap rebar will be placed on top of the stem and the remainder of the week will be spent tying the cap to the stem, installing formwork, and making final adjustments to be ready for concrete. Another crew may begin work on drainage installation required in the Barrows and Fisher yard next week as well.

The placement of 105 CY of concrete for the Pier 1 stem was accomplished efficiently yesterday and is now in its cure period. Crews are continuing work on the Pier 1 cap and will begin stripping the footing forms and conducting clean up of the Barrows and Fisher site. An additional crew is back at the VT Abutment site to make improvements to the bearing seats prior to structural steel placement. The pedestals will need to be brought up in elevation approximately 1.5″ so they will be chipped out and re-cast cleanly.

Next week, if early strength tests are adequate, work will begin on placing the Pier 1 cap steel and forms atop the stem, stripping stem formwork, possibly backfilling the footing, and removing the cofferdam sheets.

Recent favorable weather has helped the cure of the footing at Pier 1 and the strength of the concrete has allowed crews to move forward with the work on the Pier 1 stem and cap. As the stem rebar is placed and tied, form walls and corners will be set. Once the stem rebar is complete, crews will finish the cap rebar. The next concrete placement will be for the Pier 1 stem and is scheduled for Wednesday, March 6th.
