Orange Coast College Community Planetarium

  • Owner: Coast Community College District
  • Location: Orange Coast College, Costa Mesa, Ca
  • Description: New 12,124 sq. ft. Planetarium Building on the Orange Coast College Campus (Includes 100 seat Planetarium Theater, an Exhibit Ares, and a 60 ft. tall Foucault Pendulum Tower.

 

Kern Steel fabricated and installed Structural steel framing (columns, beams, braces, girts etc.), extensive concrete embeds and AESS Steel Framing.

The project manager on this job stated that some of the challenges faced were in the detailing, layout and erection of the structural steel due to the extensive use of embeds located in curved concrete walls and in the planetarium dome itself.

The placement of these embeds and their connection plates was critical to making the steel structure assembly properly. KSF employed a survey crew to assist with the placement of the concrete embeds as well as locating the field welded connection clips at precisely the right elevations and angles.

The Foucault Pendulum tower is fabricated from tube steel ellipses, sloping columns, and 'V' braces. Due to the complexity of the tower, it was completely assembled in Kern Steel's fabrication shop to ensure everything fit correctly before disassembling it and shipping it out.

 

 

Exposed skylight braces were fabricated using "Castconnex" universal pin connectors on the ends to provide a unique architectural look at the 10 curved skylights just outside the main theater area.

Finally, AESS components were a critical part of this project since there are numerous steel columns, skylight braces, canopies, and exhibit hangars that are exposed in the final construction.

The planetarium is set to open in the fall of 2018.

 

UC Davis Large Lecture Hall

  • Owner: Coast Community College District
  • Location: Orange Coast College, Costa Mesa, Ca
  • Description: New 12,124 sq. ft. Planetarium Building on the Orange Coast College Campus (Includes 100 seat Planetarium Theater, an Exhibit Ares, and a 60 ft. tall Foucault Pendulum Tower.

Project includes fabrication and installation of the following items:
• Structural Steel Framing (columns, beams, braces, girts, etc.)
• Buckling-Restrained Braces
• Stairs
• Handrails & guardrails
• Steel ladders
• Concrete embeds
• AESS Steel Framing
• Structural Mock-Up Frame

 

This project contains some logistical challenges because it is on a very tight site in the middle of an active University Campus. Deliveries had to be coordinated precisely because there are only specific times trucks can be received and the jobsite was not large enough to allow for all the steel to be delivered and shook out.

This project also included design and engineering of a mock-up structure that needed to incorporate many of the structural conditions found in the lecture hall building scaled down into a very small footprint. The mock-up structure was used by the design team to test the buildings finishes ensuring that moisture and wind would not affect the building.

AESS components were also a crucial part of the structure since there are numerous steel columns, cabana beams, and eyebrow features that are exposed in the final construction.

West Valley College

West Valley College

Location: Saratoga, CA
Contractor: Kwan Wo Iron Works
Square Footage:
Tons: 437

Kern Steel fabricated and erected columns, beams, braces and AESS rolled tubing for West Valley College, the building is a student service center consisting of classrooms, conference rooms, offices, as well as several unisex bathrooms. This project took 6 months to complete. Some of the requirements included CVN testing, MTR’s and Welding procedures.
