SUBJECT:

APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO SOLICIT

CONSTRUCTION BIDS FOR THE INSPIRATION SHUTTLE EXHIBIT AND EDUCATION BUILDING, CAPITAL IMPROVEMENT PROJECT (CIP) NO. 21-18

EXECUTIVE SUMMARY

The City Council will consider approving plans and specifications, and authorizing the solicitation of construction bids for the Inspiration Shuttle Exhibit and Education Building, Capital Improvement Project (CIP) No. 21-18. The expansion of the existing Columbia Memorial Space Center will create two new buildings, the larger of which will be home to the Space Shuttle Inspiration mock-up and several education exhibits. Full construction is anticipated to begin in February 2026 and be completed by December 2027. The City will be holding a groundbreaking ceremony prior to the start of construction, which will occur on November 17, 2025. Site preparation will occur between November 2025 and February 2026.

RECOMMENDATION

That the City Council:

Approve the plans and specifications, and authorize the solicitation of construction bids, for the Inspiration Shuttle Exhibit and Education Building, Capital Improvement Project (CIP) No. 21-18.

BACKGROUND

The Columbia Memorial Space Center is embarking on a second building expansion project (Project) to create a hub of creative and critical thinking for the youth and families of Southeast Los Angeles. This Project intends to create an integrated campus that includes a new building dedicated to bringing the community together through hands-on, minds-on learning to serve the region. The expansions includes: (1) a 39,725 square-foot building that will house the Space Shuttle “Inspiration” along with several exhibits, (2) a 15,300 square-foot building that will include two youth STEM classrooms, and (3) outdoor gathering spaces.

To date, there has been significant work to get the project ready for construction bid, including:

In January 2022, LPA, Inc, the project Architect, began the design of the Project.

Also in 2022, Rachlin Partners LLC/Huckabee, the Project Management/Construction Management firm, began providing its management services.

In 2023, UltraSystems, Inc, the Environmental Consultant, began the environmental analysis of the Project.

In 2024, Knight Building Systems, the Pre-Engineered Metal Building (PEMB) manufacturer, began its design of the PEMB structure for the building.

Today, the environmental analysis and design of the project are completed, while Knight Building System is currently completing the fabrication of the PEMB structure offsite.

ANALYSIS

Staff has completed the preparation of plans (Attachment A) for the expansion Project. The work consists of the removal of vegetation, demolition, grading, drainage, utilities, walkways, driveway approaches, lighting, landscaping, a 39,725 square-foot exhibit building standing approximately 55 feet in height, and a 15,300 square- foot STEM classroom building standing approximately 17 feet in height.

The plans are currently going through review and permitting. Staff anticipates advertising the project for bid in November 2026. Due to the complexity of the project, staff intends to keep the bidding period open through the middle of January, as there will be many construction trades that will need to review the plans to provide accurate proposals. In order to receive the most competitive bids, staff also needs to provide additional time for bidding during the holiday season.

It is anticipated that staff will return to the City Council for the award of the construction contract by the first meeting in February 2026. Construction is anticipated to begin in February 2026 and be completed by December 2027. A groundbreaking will be held prior to the start of construction on November 17, 2025. Site preparation, including clearing and grubbing, irrigation removals, fencing, and stormwater BMPs, will occur between November 2025 and February 2026.
