Construction Update Sept 9 2016
A rendering of what the completed Interdisciplinary Science Building will look like.

This is a regular update of the construction work for the Interdisciplinary Science Building (ISB) and the Parking Garage expansion on the home campus of Webster University in Webster Groves, Missouri:

Parking Lot K (located between Big Bend Boulevard and the East Academic Building) will be closed from 5 a.m. to 3 p.m. Saturday, Sept. 10. The closure is necessary as structural steel will be delivered to the ISB site. A 30-ton hydraulic crane will be temporarily constructed on Lot K to help unload the structural steel delivery truck and hoist the steel in place.  Because of forecasts of rain and possible lightning storms early Saturday, the steel delivery and erection may need to be rescheduled Sept. 11, 2016 or possibly to another date later in the month. If it is rescheduled, a new date will be published in a future construction update in Webster Today and Webster Weekly, the student newsletter.

Work crews are building a functional building enclosure (B.E.) mock-up of critical BE material interfaces at the south-west corner of the construction site, just inside the fence on Lot K. The mock-up will include the air and vapor barrier, fenestrations (windows and curtain wall systems), masonry, and metals panels systems, etc. that will be used on the building. The B.E. mock-up will be onsite throughout the construction of ISB building enclosure systems.  The construction duration for this mock-up is 9/1/16 to 10/14/16

The Functional B.E. mock-up will be used for several purposes:

  1. It will allow the inspection and testing of the critical B.E. material interfaces, air and vapor barrier, and fenestrations to make sure there are no constructability deficiencies or water and air infiltration issues prior to the construction of the ISB’s B.E. systems.  A third-party testing laboratory will visit the ISB job site and test the B.E. mockup. This process will help determine if modifications are needed before the full building is completed.
  2. It will allow the architects to visually inspect the aesthetic qualities of the B.E. materials and make sure they comply with the basis of design and construction documents.
  3. It will be used as an education tool for on-site tradesmen so they have a reference for how the B.E. systems must be constructed.

In other ISB construction updates:

  • The installation of grade beams at Level 0 (lowest level) at backfill area should be completed in the next few days
  • Foundation walls at Level 0 backfill area will be installed starting next week.  
  • Steel erection will continue through Oct. 25
  • Concrete slab-on-grade will be poured at Level 1 Area B at the end of the month.
  • Starting Sept. 28 and lasting through Nov. 3, mechanical, electrical, and plumbing rough-in will occur at slab-on metal decking at Levels 2 thru 4.

At the garage expansion construction site:

  • The barriers blocking access to the sidewalk in front of the bookstore have been removed and sidewalk access to the book store and garage entrance has been restored. Some fencing will remain in place to protect landscaping.
  • Workers will be spreading straw and seed in the area to minimize the spread of dust and mud in the near future.
  • Construction crews have completed three of the 40 drilled piers needed for the garage.
  • The installation of the new storm water mains are complete. The old sewer lines will be abandoned and filled with grout.

Construction traffic will remain high on Garden Avenue as each pier placed will require several loads of concrete.  Flagmen and safety monitors will be in place to direct traffic.
