BL Harbert International’s team on the U.S. Embassy project in Ankara recently achieved a major project milestone in the successful completion of a large, monolithic concrete placement for the Support Annex building (SPX). The monolithic placement, which occurred over a 15-hour period, was for the mat slab foundation and contained just over 3,300 cubic meters of concrete.
The first concrete ready-mix truck arrived on site the morning of Saturday, March 10th at 8:00 am, and the last truck left the site at 11:00 pm. The work was completed using five concrete pump trucks, with boom lengths varying from 38 to 56 meters, strategically set up around the SPX footprint. Now complete, the mat slab is one meter thick and contains roughly 367 tons of rebar. On average, BLHI’s Ankara team placed 264 cubic meters of concrete per hour, with the best hour reaching 319 cubic meters!
Team members worked in multiple shifts throughout the placement without incident.
Project Manager, Brian Kosoglow sees the success of this concrete placement as a major milestone in the project and a sign of good things to come. The BL Harbert team is currently planning an even larger monolithic concrete placement for later this summer. This placement will be for the parking garage mat slab and is estimated to contain over 4,350 cubic meters of concrete, and the team is looking forward to this challenge.
