Construction Update June 24 2016 Tower Crane

ST. LOUIS - The tower crane will be constructed from July 7 to July 12. Parking Lot K will be closed to both automobile and pedestrian traffic during that week. On Saturday, July 9, the Priest House, the Pearson House and parts of the East Academic Building will need to be empty as a safety precaution.

Once erected, the tower crane will move large loads and steel girders into place for the Interdisciplinary Science Building (ISB) construction project.  It will remain on site until early next year.

“This is the first time that a tower crane has been used for a construction project on Webster University’s campus, and I know they are an unusual site in Webster Groves,” said Craig Miller, Sr., Webster University’s ISB project director. “Safety is our top priority and we want to make sure the community knows we have studied this closely, are working closely with the city, and have systems and protocols in place to keep everyone safe.”

The tower crane will be brought to campus in pieces and will be partially assembled and laid out in the Parking Lot K. The jib of the tower crane will be 220 feet long and therefore will take up much of Lot K as it is assembled. A smaller mobile hydro crane will be brought in to help hoist parts of the tower crane in place.

The hydro crane will arrive on July 6 and will be parked inside the area of Lot K that is currently fenced off. Starting at 6 a.m., July 7, the lot will be closed and the construction crew (flagmen) will be on site to direct trucks into the area, as well as to help direct all other traffic into Lot J (located west of the Thompson Music Building) or out of the lot.

On July 9, the Priest House, the Pearson House and the entire north wing of the East Academic Building will need to be empty when the hydro crane hoists parts of the tower crane into place. Here is a timeline of the project:

Wednesday, July 6th 

  • The parts of the hydro crane will arrive on-site in the morning and be parked inside of the fenced staging area in Lot K. 

Thursday, July 7th

  • Lot K will close to all non-construction traffic starting at approximately 6 a.m.  Red danger/barricade tape and cones will be placed at all sidewalk and driveway entrances that lead to Lot K to prevent vehicular and pedestrian access. 
  • The hydro crane erection will begin and approximately 15 trucks will arrive with the crane pieces necessary. The erection of this crane will take most of the day.

Friday, July 8th

  • The tower crane components will begin to be delivered.  The jib sections will arrive first, and they will be assembled on the ground in Parking Lot K.  Approximately mid-morning, the tower crane sections will be hoisted into place and stacked vertically on the tower crane base, just east of the Priest Carriage House.  By the end of Friday, the tower and house sections will be in place.
  • No loads will be flown over any occupied buildings during this day.

Saturday, July 9th

  • The tower crane’s jib will be lifted into place and it will be lifted over the ISB building’s footprint. However, if the wind does not cooperate, there is a small chance it may swing over the Priest House, the Pearson House and the north wing of the EAB.  Therefore, these buildings and areas will need to be closed on Saturday, July 9th, from 5 a.m. until 6 p.m.

Sunday, July 10th

  • Day off.

Monday, July 11th

  • The tower crane will be tested and calibrated, and will begin operation once everything checks out.
  • The hydro crane will begin to be disassembled and reloaded onto the trucks.

Tuesday, July 12th

  • The northern portion of Lot K will be used by staging trucks until the late afternoon. As a result, the lot will be closed for the entire day.

During the rest of the construction project, the tower crane will not be allowed to swing loads over the Priest House, Pearson House, EAB or the carriage house. The arm of the crane, because of its length, will occasionally pass over these buildings, but any loads being carried will be adjusted to only be carried over the footprint of the ISB.

By early January, 2017, the ISB should have its exterior “skin” installed and construction work will then move indoors so that workers can complete the interior. Once that phase is reached, the tower crane will be deconstructed.

The ISB is expected to be finished during the summer of 2017 and open when students return for the fall 2017 semester.
