Construction crews began securing the project perimeter, an entire city block, Sunday night with steel, chain-link fences and large yellow barriers along the sidewalks, preparing for the two-year construction process of the glass-faced, 400,000 sq. ft. structure. World-renowned architecture company Pelli Clarke Pelli (PCP) aims to bring San Antonio's skyline into the 21st century with its design.

The project is slated for completion by late 2018 or early 2019.

For now, a few piles of rubble dot the site, which was the Frost Bank motor bank and parking lot. A few construction workers in bright vests and hard hats work to weld large steel gates together to mark the entrances to the future construction zone while a dozen or so others are erect tall fences around it to keep out overnight intruders and pedestrians. The entire site is expected to be secured by Tuesday night, one construction worker told the Rivard Report Monday morning.

PCP has been working with Weston Urban, the project's developer and investor, and local architectural consultant Alamo Architects on the high-profile tower project that is part of a multi-million-dollar real estate deal with the City of San Antonio. The City will take over the former Frost tower Houston Street once current tenants move out and the building is renovated.
