MULTI-UNIT HOUSING
The range of our housing projects include Apartments, Condominiums, Senior Housing and Student Housing.
Apartment buildings with Post-Tensioned concrete can be built in a cost-effective manner and thus maximize the payback to the developer or asset-manager. The 1-3 day concrete pour cycles can expedite the construction schedule so that residents can quickly occupy units.
1620 S. MICHIGAN
Project Name: 1620 S. Michigan
Location: Chicago, IL
Contractor: Adjustable Forms
PT Quantity: 600,000 feet
Facts: The 14-story, 350,000-square-foot structure features 10-foot ceiling heights. AMSYSCO provided value-engineering ideas that converted the project to a PT system and saved $2.00 per square-foot.
High-rise and mid-rise condominiums can benefit from the reduced building height from a Post-Tensioned structure. This benefit reduces the cost of other vertical elements. Additionally, the reduction in columns can offer flexibility in the Architected floor plan.
340 E. RANDOLPH
Project Name: 340 E. Randolph
Location: Chicago, IL
Contractor: McHugh Construction
PT Quantity: 1.2 million feet
Facts: The 64-story, 975,000-square-foot luxury condominium tower is one of the tallest residential PT projects in the U.S. Each floor had a three-day cycle and curtainwall/MEP embeds that had to be coordinated with the PT system.

VILLAGE GREEN
Project Name: Village Green Condominium
Location: Arlington Heights, IL
Contractor: Corrigan Construction
PT Quantity: 375,000 feet
Facts:The low-rise building had a large footprint that was originally designed in conventional rebar. AMSYSCO proposed an alternate flat-plate PT slab system. In addition to a reduction in the slab thickness by 3.5”, the PT system deleted many beams. This resulted in a considerable savings to the owner and more open layout for the architect.
600 N. FAIRBANKS
Project Name: 600 N. Fairbanks
Location: Chicago, IL
Contractor: Adjustable Forms
PT Quantity: 750,000 feet
Facts:The 41-story, ultra-luxury condominium tower has 12 parking levels and a lap pool. The 60-foot curved façade required detailed coordination drawings since there was no access for stressing on two sides of the building. The use of thin PT slabs resulted in roughly $2.0 million savings in the vertical window-wall system.
Monolithic Post-Tension concrete can reduce floor deflections within your senior housing facility. The vibration-control occurs due to the draped Post-Tensioning tendons transferring dead-load directly to the columns.
ADMIRAL AT THE LAKE
Project Name: Admiral at the Lake
Location: Chicago, IL
Contractor: Adjustable Forms
PT Quantity: 1.0 million feet
Facts: This retirement community consisted of one post-tensioned building with a staggered roof up to the 31st level. The first six floors include a parking structure, a swimming pool and residential areas. Each senior-living apartment unit has a balconies and other amenities.
GARLANDS OF BARRINGTON
Project Name: Garlands of Barrington
Location: Barrington, IL
Contractor: Pepper Construction
PT Quantity: 2.0 million feet
Facts: This senior living project consisted of four PT low-rise buildings. Each building had a large footprint and a column layout that was not aligned. This caused the tendons to have extensive curves in the plan. Extra length was added to the tendons to achive simplicity in the field.
Two-way Post-Tensioned concrete slab can eliminate costly drop capitals and increase the floor-to-ceiling clearance. PT reinforcement
UNIVERSITY CENTER
Project Name: University Center of Chicago
Location: Chicago, IL
Contractor: Adjustable Forms
PT Quantity: 900,000 feet
Facts: The 20-story student housing structure used a 9.5” PT slab in order to eliminate the need for drop heads. In order to accelerate the concrete schedule, expansion joints were eliminated in favor of one pour strip. This shaved two months off the original schedule.
