Since June 2016, The Conco Companies have been supplying concrete services for The Mark at 5th & Columbia project. As a reminder, the project consists of a 528,000 sqft office space, hotel, and spa scheduled to be completed by April 2017. The building boasts a number of green building features and hopes to seek LEED Gold certification. The initial concrete mat foundation pour, completed in June 2015, required 500 truckloads of concrete alone.
The project is progressing beautifully. As of August 2016, the concrete core stood at its final height (48 stories) and the focus shifted to completing the remaining concrete pours for the structural decks and garages. Remaining concrete pours for the month of August commenced at a pace of 2 per week until Level 28 was reached. Structural steel was installed in August and roof steel was installed shortly after, bringing an end to the steel erection process.
The project really ramped up in September when concrete pours were increased from 2 per week to 3 per week with the goal of completing all concrete decks up to level 4. This pace continued through October until level 45 concrete cement decks had been successfully poured.
Parts of the garage, which have been poured, are being polished with final paint and signage. The next major project milestones include the rooftop mechanical and structural assemblies, podium construction for levels 1 through 5, mid and high-rise elevators, and the removal of cranes as the project moves onward.
