The Cannon Rotunda, an area of special architectural interest in the building's interior, is located at the main entrance of the building and has a diameter of 57 feet 4 inches. Eighteen Corinthian columns on a marble arcade draw the eye upward and support a richly detailed entablature and coffered dome. Members located in the Cannon Building's four construction zone phases were relocated in at the end of the Congressional session for the following session. All House members have a suite located in the Longworth, Rayburn or Cannon House Office Buildings.

There are a number of factors that make a city attractive for businesses to relocate or expand, as well as for investors to enhance their portfolios through local acquisitions. Among the most important factors to consider are the size and quality of the local office market, which is an essential component of the local economy. The campus creates a safe and nurturing environment with an abundance of resources for a population who struggles with access to basic needs. The Restorative Care Village represents an innovative new approach to providing medical, mental health and addiction, and housing services for underserved and vulnerable communities—providing the support needed to reintegrate into the community. It also serves residents of Lauderdale County from roughly Killen, west to the Mississippi line. This office serves Marshall (with the exception of Arab, Union Grove and Cherokee Ridge), DeKalb and Etowah counties.

Member offices will flank both sides of the corridor, as they do on the lower floors. Work includes demolishing the walls and roof, then rebuilding an entirely new fifth floor. The renewal process is scheduled to take approximately 10 years, with each of the five phases (0-4) aligned to fall between Congressional move cycles.

The Cannon Building's Refreshed Rotunda

"The columns are still beautiful," said Klee, "and they reflect a balance between safety and preservation that we needed to strike for this particular project." The building was designed in the form of a hollow trapezoid to admit light to inner offices. On each floor the mahogany doors of the offices flank a 12-foot-wide corridor. There were 397 offices, one for each representative in the 61st Congress, and 14 committee rooms.

MLK Child and Family Well-Being Center

On hand to discuss the renewal project were Architect of the Capitol Stephen Ayers; Superintendent of House Office Buildings William Weidemeyer; and Historian of the U.S. We testified on project status and cost estimates as part of our assistance with congressional oversight. In some cases, that meant removing loose bits of stone from the columns that could not be securely pinned in place. The small nicks and gaps left behind reflect a treatment where less is often more and any repair work done is seamless or not done at all.

The property is owned by McCarthy Cook and was built to attract LA’s tech and entertainment firms. The MLK Child and Family Well-Being Center will be the newest addition to the Martin Luther King Jr. County is that it has leveraged nearly all our firm’s capabilities—from architecture and engineering to construction, facility optimization, software development, workplace strategy, modular prefabrication and more. No matter the challenge, we bring our unwavering commitment to innovation to L.A. County, pulling from our vast array of integrated services to deliver transformational solutions that are benefiting all corners of the expansive region. It also serves the portion of Tuscaloosa County primarily north of the Black Warrior River.

The AOC's construction representative, Ryan Columbo, led a behind-the-scenes tour after the initial briefing. According to Columbo, the building’s chilled water valves are over fifty years old, and the steam valves are original to the 1908 building. Replacing the corroded steel pipes is not just a cost-saving measure, but it will allow greater control over the systems as deterioration has made it difficult for water to flow.

The Cannon Renewal Project, taking place from 2014 through 2025, involves a thorough renovation of the entire building and addresses accessibility and structural issues. The project will conserve and repair the exterior and interior stone and wood, rehabilitate office spaces, and complete a comprehensive infrastructure upgrade, including heating, cooling, lighting, plumbing, fire, and life safety systems. The work also includes the removal of the previous fifth-floor addition—the marble flooring was preserved, however—before building a new, more expansive fifth floor.

In January 2018, AOC updated its analysis of risks by undertaking an integrated cost-schedule risk analysis. AOC's 2018 analysis arrived at the same conclusion as its earlier analysis—that the project's estimated $753 million total cost was adequate to complete the project. However, AOC's 2018 analysis indicated that inaccurate estimates of costs for risk mitigations, unknown risks, and optimistic assumptions about the effect of risk mitigations on the project's cost and schedule could affect its total cost. AOC updated the analysis in December 2019 and estimated the project cost at $890 million. These new offices for Members of Congress dramatically changed how the House of Representatives worked.

During the Cannon Renewal, the rotunda's original plaster dome was repaired and painted the historic color, which carries the color of the stone columns up through the cornice and dome to the skylight. The intent is to make the Rotunda look as if it was all made of stone — similar to ancient Greek and Roman structures. The skylight, which was replaced during the project, now allows natural light to filter through the space, highlighting the rotunda's impressive architectural details.

In response to COVID-19, our Blue Cottage of CannonDesign team worked with L.A. County to rethink workplace strategies specifically aimed at reducing leased building space. Our team re-envisioned the county’s portfolio of administrative facilities, resulting in a six percent reduction in leased space and a 14 percent reduction due to alternate ways of working. Our work involved assessing individual departmental needs, evaluating leases, and analyzing and optimizing the total portfolio. County with the potential to realize annualized savings of up to $7 million through lease terminations. How can the Architect of the Capitol ensure the project delivers good value to the taxpayer?

The barriers at Washington Ave, SE and Independence Ave, SE are open at all times. The deal will see ELARC increase its footprint at The Alhambra by 23,345 square feet, bringing its total to just under 147,000 square feet. LA’s robust office market encompasses properties in major financial centers, including the Financial District and Bunker Hill in the city’s downtown.

U.S. Capitol Police closed several roads in the area Wednesday afternoon, but they have since reopened. At 5 p.m., the group was still in the Cannon rotunda chanting "Free Palestine" and singing. Within an hour, though, police announced the rotunda had been cleared and said they were continuing to process the arrests. Officers were still processing the arrests, so they don't have exact numbers yet.

As an authority on historic preservation, the Architect of the Capitol (AOC) follows conservation principles. The renewal of the Cannon House Office Building is an example of the AOC's commitment to preserving our nation's history one project at a time for future generations to appreciate and enjoy. L.A. County is the most populous county in the United States with 9.9 million residents spread across 88 cities.

The Architect of the Capitol is committed to maximizing taxpayer value, reducing the risk, and minimizing disruption to the work of Congress. Similar projects have been conducted throughout the executive branch including the Eisenhower Executive Office Building and the headquarters of the Departments of Interior, Justice, Treasury and Commerce. This office is located on the backside of the Cullman Dental Arts building up the handicap ramp.

In order to support the building with much of its foundation over this tunnel, engineers had to drive concrete pilings 26 feet deep. The Guastavino Company used patented techniques to construct a masonry vault in the building. The company brought to the U.S. a tradition of Catalan vault-building with roots in masonry techniques from around the Mediterranean. Multiple layers of thin tile laid with Portland cement in a herringbone pattern create a beautiful arch; more importantly, such vaults are strong and fireproof, quick to construct, and require fewer building materials. The Guastavino Company built a similar vault in the Russell Senate Office Building and completed structural tile vaults and a spiral staircase for the Supreme Court building. The vault in the Cannon Building supports the weight of the building's Rotunda.
