Goldwin Smith Roofing & Klarman Hall Groundwork Project Photos

April 9, 2014 // by Jason Henderson


There’s been some considerable equipment mobilization on this site since late March with the addition of a boom crane and a pile hammer, possibly a vibratory model for noise and speed considerations. The pile hammer is for beam shoring (geo-shoring) along East Avenue, in order to hold the hill together once the site is dug out quite far down for Klarman’s footprint. After the steel beams are in ground, they are followed-up with lagging boards, which are affixed to the beams for soil retention.

Goldwin Smith Hall’s central eastern-side roof has progressed with re-slating and new metal roofing installation, which will continue along that end, and also the south wing’s southern side. The schedule indicates that underpinnings on the south wing of Goldwin Smith Hall have been completed, and will continue along the rotunda area this month.

Klarman Hall Schedule & Goldwin Smith Roofing for March

March 26, 2014 // by Jason Henderson

Cornell University’s Klarman Hall project has posted a schedule for the next six months, while LeChase Construction and Welliver have completed more roofing work throughout the month of march. The southern wing’s roof looks nearly complete, along with most of the southern portion of the main building, as the previous slate and metal roofing has been completely removed, re-surfaced with synthetic underlayment, and replaced with new slate and metal.



Underpinnings for Goldwin Smith and Klarman’s foundation have begun installation as indicated on the schedule. They’re typically used to support an existing foundation by digging underneath section by section, and backfilling the trench with concrete to provide additional support and stabilization. The crews will be digging all along Klarman’s future footprint, and along East Avenue. The future weight of Klarman Hall would likely have an adverse affect on existing footings as the new building settles into the soil, so the work will ensure that the existing foundations are safe and sufficient. For certain situations (especially repairing unlevel settling), a building’s foundation is actually jacked up with hydraulics to fix the level.

Goldwin Smith / Future Klarman Hall February Site Photos

February 24, 2014 // by Jason Henderson

A few more windows on the east side of Goldwin Smith Hall have been boarded-up, and roofing work as part of the enabling work scope for the Klarman Hall project has been proceeding (LeChase Construction), as the entire existing slate and metal roofing materials are replaced with new metal, flashing, and slate pieces. If I’m not mistaken, I believe by this point, the entire north wing, the northern-central section, and the southern and northern slopes of the south wing have new slate installed. The Cornell Chronicle posted an article about how the temperatures have been affecting the project.

The target completion for Klarman Hall is late 2015, with 33,250 square feet of new space going for LEED Platinum certification, a 350 seat auditorium, and a large inner-atrium space, opening-up the Goldwin Smith rotunda for cafe-service areas and entry/egress into Goldwin Smith. Embedded images for each of the four floor plan levels are here in the previous post. Welliver is the general contractor on this project.






Klarman Hall, Goldwin Smith Project Photos & Updated Floor Plans

February 3, 2014 // by Jason Henderson

Goldwin Smith Hall’s windows are completely boarded-up on the east sides facing East Ave, which has been closed to vehicular traffic minus bikes and busses starting a couple weeks ago. Construction fencing has been bumped-out into the western lane, and temporary lights have been installed to manage the traffic flow across the one lane. Roofing work on Goldwin as part of the enabling project is still progressing, but once that’s complete, we should see some further excavation work towards the very edge of East Ave, in order to install the retaining wall for the the eastern side of Klarman Hall that will be below ground level.
Cornell has setup a project page here with newly released floor plans, an FAQ section, and some additional information. Floor plan images posted below.

Goldwin Smith Hall Roofing

January 1, 2014 // by Jason Henderson

Slight progress since November, but I would bet that much of this is on hold until the holidays are over or once the weather is a bit more forgiving. The roof of Goldwin Smith Hall is being replaced as part of the enabling work for the Klarman Hall project. The new electric and telecom concrete duct along East Avenue has been covered over now, so further excavation and the remaining enabling work will probably be completed early this year to prep for construction season.



Klarman Hall Progress, Goldwin’s Roof Replacement

November 30, 2013 // by Jason Henderson

Goldwin Smith Hall’s roof replacement project is well underway, and there’s a new concrete electric and telecom duct along East Ave. that has been run and poured as part of the enabling work for the Klarman Hall project. There’s a photo grab of the section below, showing the new service area, and where the new building’s retaining wall will sit. The future sidewalk area will be directly above the duct, and then offices will be built-in beneath this grade right beyond the retaining wall.



Klarman Hall: Goldwin Smith Electric Duct and Scaffolding

October 17, 2013 // by Jason Henderson

The electric duct running around Goldwin Smith from East Ave. has been wrapped and is being covered-up again with soil and stone. It’s hard to tell from the photo, but the inner southern wing of Goldwin Smith has scaffolding running all the way up the side of the building. It looks like there’s new metal standing seam roofing material along the roof edges (the old lead coated copper stuff is going away), as called for in the roof replacement documents. Also, the plan is to cover all of the windows with sheathing to minimize any damage from the construction, especially the blasting of the hill to excavate for the retaining wall along East Ave.





Klarman Hall Site Prep Photos

October 8, 2013 // by Jason Henderson

More site prep is underway at the future site of Klarman Hall on East Ave for a construction mobilization in early November. There is a series of concrete manhole access forms on the northeastern corner of the site, and there’s a long section of walkway that has been excavated in front of Goldwin Smith Hall on the southern side, revealing the concrete-encased electric duct (according to the utility & demolition plan, embedded below) running from the southeastern corner clockwise around the building to the front. I’m spotting a couple generators outside the in-ground electric room, which will be re-worked as part of the project as well.
It will be interesting seeing this hillside blasted and dug out for the new retaining wall. Part of the building will literally have offices sited underneath the new sidewalk runs along East Avenue running the length of Goldwin Smith Hall, with lit skylight arrays running north-south that protrude above ground several feet. The excavation will be going quite deep, almost right up to the edge of East Ave.

Klarman Hall Site Prep-Work Updated Photos

September 19, 2013 // by Jason Henderson

The future Klarman Hall’s eastern side along East Ave. has some preliminary excavation work with a small excavator and a dump truck. We’ll probably see a relatively level surface work its way down as the excavator chips away at this steep grade so that it can stay stable. Lots of soil to move though- all the more reason a concrete retaining wall will be going in this February.


Klarman Hall, Goldwin Smith Roof Replacement

September 10, 2013 // by Jason Henderson

In addition to the Klarman Hall project, Goldwin Smith Hall’s roof will be undergoing a replacement at the cost of around $5 million (including some Klarman Hall enabling work). First, the metal and slate material will be removed, then a series of minor geometric changes will be made (from the drawings, it looks like they’re intended to provide better drainage and snow drip to the eave corners, preventing buildup and eventual leakage). The eave and dormer details look about the same, so once the roof is replaced, it will be hard for someone to spot the difference coming back as an alumni.. nothing like what it will be like to look at the East Ave side and see Klarman Hall consuming the former dead space on the eastern side. The roof replacement draft details are embedded below.
