Tompkins Financial Corporation HQ Construction Update, 12/2016

18 12 2016

The future headquarters of Tompkins Financial Corporation is starting to rise from the ground at 118 East Seneca Street. The elevator core and south stairwell are being poured section by section. Forms are being put into place to build the next level of the core. It looks like structural steel surrounded by concrete fortified with steel rods (rebar). The small holes within the elevator core are where the structual steel of the superstructure will tie in. The basement appears to be fully excavated with all the wood lagging in place. The four H-shaped steel bars next to the elevator core are piles, which will carry the building load. More on those in a minute.

The basement for the TFC HQ is a bit of an unusual setup. The excavated portion (12-13 feet deep) only encompasses the floor plate for the basement and ground floor. The second to seventh floors will have larger floor plates. The elevator core actually sits at the northeast corner of the ground floor’s floor plate – the area between it and the Hilton Garden Inn will be the driveway, and behind it, the customer parking lot. Stairwells to the upper levels will also rise on the northeastern boundary of the property, and the northwest corner of the first floor, close to the parcel’s lot line with the DeWitt Mall. The upper floors will have the support of additional load-bearing columns along the perimeter of the property (they will tie into the end-bearing steel foundation piles seen here in August, which seem to be capped and at ground level now).

Along with the perimeter piles and the piles within the ground floor plate, four support columns will rise from through the parking area to the floors above. Those appear to be pile caps for two of those support columns in the second to last photo. The four H-shaped steel bars are capped with a thick block of concrete from which the support columns will tie into, and use as their base. The weight of the building will be transferred through the steel structure, through the pile cap and evenly distribute the weight into those piles, which will transfer the load down into very firm soil 65-70 feet below ground level. This is what will give the building its stability.

Anyway, seems like I forgot to take photos of the drive-thru bank branch under construction across the street – which is probably close to completion at this point, if not already. The $31.3 million office building will open in March 2018. LeChase Construction is the general contractor, and HOLT Architects is responsible for the design.

Good stuff. Can’t wait to see the Seneca Street canyon (or should I say gorge…wink-wink) when this building is completed. Now if only something similar would happen on the SE corner of Seneca & Tioga. Thanks BC.
