BROAD & RACE - JULY 2008 (START OF CONTRACT 1)


BROAD & RACE - DECEMBER 2009


The Keating Joint Venture (KJV) is a partnership between Daniel J. Keating Company and Keating Building Corporation

KJV is a unique combination of builders with large project experience and hard bid general contractors

Awarded Contract 1 in June 2008 and Contract 2 in October 2008

Total current combined contract value $470,998,117


Site turn over from Demolition Contractor in 2 phases, East to West, split at Juniper Street

Contract 1 milestones with liquidated damages ensure readiness for Contract 2 and set initial sequence and schedule

Drilled pier operations needed to begin immediately. Two shifts for two rigs,6 days/week

Starting point of Concrete Superstructure is T line with Expansion Hall slab to the North and 5 story Arch Street Concourseto the South


Schedule is divided along expansion joints.

Presentation

The best planning aid we had were photographs of the original construction and the world’s largest mock up, the existing Center.Studied difficulties encountered by original contractor in forming waffle slab. Constructing and poured full scale mock ups of waffle slab, done off site.

September 2008Expansion Project

Presentation

Work initiated September 3, 2008

Work planned to progress on East sidefrom South to North, starting at T line

After drillers reached Race Street,The rigs would return to the West side at T line and progressSouth to North again

October 2008


Demolition of the West side of the existing Center also progressesfrom South to North, as does sewerReplacement in 13th Street

November 2008



In October and November of 2008 the redesign of the southwest corner of the Expansion building requires rethinking of the schedule

Caisson rigs will now complete East half of site and work West half from Northto South

December 2008


January 2009


February 2009


February 2008


February 2009


The new construction sequence requires change in logistics planning. Demolition of the existing façade and 13th Street utility work is accelerated.

This allows for an earlier start and completion of Area 2, which in turn allows construction of temporary ramps to the Exhibit Hall floor.

Materials and equipment now flow through the loading dock.

The Mechanical/Electrical nerve center gets a much earlier start in Contract 2.

Presentation

August 2009


Once enough waffle slab is completed, steel trusses are constructed on the deck and lifted into place in sections by tower cranes.

Steel also progresses in both directions.

August 2009


Steel for trusses is

delivered via the loading

dock


Presentation

September 2009



Presentation


Economic conditions benefit the schedule as skilled labor is more readily available and material and equipment lead times are significantly reduced

September 2009

October 2009


With steel, equipment and labor all available, a third crane is added to the erection effort

October 2009


November 2009



The project is currently a few weeks ahead of schedule

The critical path for the remaining work runs through the Broad Street Curtain Wall and Lobby

The Curtain Wall is currently in the mock up stage and construction should begin in the spring.
