The Reed at Southbank

Location: Chicago, Illinois

Award: Architectural


Project Team

Owner: Lendlease

Contractor: McHugh Concrete Construction

Architect: Perkins and Will

Engineer: MKA

Concrete: Oremus Material

Slag Cement: Skyway Cement



The Reed at Southbank is a 43-story cast-in-place concrete structure that required over 30,000 yd3 (23,000 m3) for the first high-rise using low-carbon concrete in Chicago, IL, USA. Oremus Material and Master Builders Solutions collaborated to provide concrete that had great performance, pumpability, and finishability, and also an aesthetic finish for the exposed columns and ceilings.


The use of slag cement aided in the low heat mass placements, improved pumpability, improved sustainability, and achievement of high-strength concrete with aesthetic appeal.


The use of concrete mixtures with low GWP allowed for obtaining 18-hour high-strength concrete for post-tensioning applications necessary for 3-day deck cycles to maintain McHugh Concrete’s efficient high-rise schedule.
