The
final beam was hoisted into place on April 6, 2017 topping off the new
Salesforce Tower in downtown San Francisco, which is the tallest building west
of Chicago. While the new Wilshire Grand in Los Angeles has a spire that actually
makes it higher in height, the San Francisco tower will hold the honor of
having the highest occupied floor. The
61-story skyscraper, located at Mission and 1st Street, and has been
under construction for four years.
The Conco Companies provided concrete services on the 1,070 ft. skyscraper. We announced last November that we successfully completed the final core wall pour and that it was now officially the tallest building in San Francisco. One year before that, we completed the 12,000 cubic-yard mat pour for the tower and set a record for the largest pour in San Francisco’s history.
Before
construction of the Salesforce Tower, the 853 ft. tall Transamerica Pyramid had
held the record as the tallest building in the city for 43 years. Another skyscraper, the Millennium, just a
block away from the Salesforce Tower is garnering attention for the fact that
it has sunk 16 inches from when it first opened its doors in 2009. To further complicate matters, the
condominium building is sinking unevenly.
While the Millennium’s foundations rest on 950 friction piles, they do
not go down to the bedrock as does the Salesforce Tower’s foundation, which is
anchored to bedrock.
The
developer of the Salesforce Tower, Boston Properties reports the opening will
be rolled out in phases beginning in July and continue through to 2018. Spokesperson, Michael Cantalupa, said,
"The steels been finished, concrete finished, the skin of the building is
coming up. In terms of later phases of construction, the building needs to be
fit out for its tenants. So, each tenant that comes in, its space is going to
be designed and constructed for its particular uses."
