Steel Erectors at Work on Klarman Hall

October 8, 2014 // by Jason Henderson

Cornell’s future 33,250 square foot Klarman Hall project being built by Welliver has finished-up the north and south foundations, and steel erectors are on site craning and bolting steel columns and beams in place on the south end. The columns are anchored to each foundation footing cap or pier, then the beams between each column are bolted and welded to the proper connection. The north end’s steel work should be completed by early November, and we’ll see the atrium steel assembly commence and complete throughout November.

Klarman Hall Mid-August Photo Update

August 16, 2014 // by Jason Henderson

Here’s a photo update (July 29th to August 14th) for Cornell’s 33,250 square-foot Klarman Hall project, a new Humanities building to be situated between the wings of Goldwin Smith Hall along East Avenue. Over the past few weeks, rebar and concrete forms for the south end and north end footings have been assembled and the south end footings and western foundation walls look partially completed. The shoring wall along East Ave is being prepped for pouring concrete as well, as large steel concrete forms are craned into position to sandwich the rebar assemblies between the form and shoring wall. Steel erection over top of the south end’s foundation walls begins later this month, and by mid-September, the north end foundation walls will be completed and ready for structure assembly.

The building is designed by Koetter | Kim & Associates, with construction by Welliver.

Klarman Hall Project Digs Bedrock, Constructing Footings

July 26, 2014 // by Jason Henderson

Excavation work for Cornell’s Klarman Hall Project between the wings of Goldwin Smith Hall has been making its way into bedrock, as Maine Drilling and Blasting has removed stone in the northern and southern blast zones. The foundation footings follow-up after the rock blasting, and it looks as if Welliver has constructed a series of rebar bends to form the reinforcement for some of the southern footings below. It’s been interesting getting a glimpse of the outside wall of Goldwin Smith Hall’s foundation: just a combination of stone, brick, and mortar, probably well over 2 feet thick. The building was originally constructed in 1892, around the time the two-way telegraph was invented to put things into perspective.

Klarman Hall Digs Deeper

June 18, 2014 // by Jason Henderson

Rock removal and blasting began late May by Maine Drilling and Blasting, as the project reaches further into the ground, removing rock and soil for the future foundations of Klarman Hall, which will sit between the wings of Goldwin Smith Hall. The shoring beams are tied with lag boards to support the hillside as the digging goes deeper, but the blasting should be finished-up by July. Here’s an updated project schedule from the project page:

18 Jun 2014 | East Ave Shoring complete
24 Jun 2014 | Complete Rock removal South
01 Jul 2014 | Complete Rock removal North
16 Jul 2014 | South Footings complete
06 Aug 2014 | North Footings complete
27 Aug 2014 | South Foundation walls complete
28 Aug 2014 | Steel erection begins
17 Sep 2014 | North Foundation walls complete
01 Oct 2014 | South Steel Complete
05 Nov 2014 | North Steel complete
19 Nov 2014 | Atrium steel installed

All the underpinnings were completed last month, and we should be seeing foundation work start in the next couple weeks. Concrete forms will be situated starting at the south end, then steel reinforcement tied in-place, then concrete poured into the form. The foundation walls and steel erection phases will also go from south to north, so by the time northern foundation walls are being formed, structural steel will have begun placement on the south end. Should be a nice one to watch as it goes up. Quite an elevation change too; this one starts well below-grade, a lot like the recent Law School Expansion, constructiom which was also managed by Welliver. The design for Klarman Hall is by Koetter | Kim & Associates.

Cornell Klarman & Goldwin Smith Hall Photo Update

May 18, 2014 // by Jason Henderson

An excavator has been removing soil in front of the shoring wall along East Ave, and re-roofing work on Goldwin Smith has progressed to the west side of the building, facing the Arts Quad. I’m not positive, but in looking at the drawings, there must be another shoring wall to go in closer to East Ave. in order to excavate another section of soil for the future building’s foundation. The project schedule shows rock removal beginning about a week from now, so there’s probably a solid layer of bedrock underneath the excavated area. The lowest floor of Klarman Hall will sit nearly equal with Goldwin Smith’s lowest floor, so the excavation will be going down much further.

Klarman Hall will be a new 33,250 square foot Humanities Building, designed by Koetter | Kim & Associates and built by Welliver to be completed around the end of 2015. Goldwin Smith Hall was built in 1892, designed by Charles Osborne (an architecture professor), Carrère and Hastings (a prominent Beaux-Arts/neo-classical architecture firm).

The metal shoring beams along East Ave appear to have been completed since early April, and the slate and metal re-roofing of Goldwin Smith Hall has progressed to the far southern edge. Foundation underpinnings for Goldwin Smith Hall will continue for the rest of this month, then further excavation of the hillside will take place along East Ave to prepare for structural foundation work for the future Klarman Hall.

Goldwin Smith Roofing & Klarman Hall Groundwork Project Photos

April 9, 2014 // by Jason Henderson

Goldwin-Klarman-Cornell-Ithaca-040614-22

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.

Klarman-Construction-Schedule

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.
