The document discusses the use of unbonded post-tensioning for infrastructure projects. It begins with an overview of concrete versus asphalt pavements. Unbonded post-tensioning can be used for applications like airport runways, parking lots, and pedestrian bridges. The document then presents three case studies where unbonded post-tensioning was used: a road project in Wayzata Bay with poor soil conditions, an emergency vehicle operator course, and a reconstruction project on Buford Avenue. It concludes that unbonded encapsulated post-tensioning is an effective alternative to reinforced concrete or asphalt for infrastructure projects.CTBUH Innovation Award Nominee - Vertical Unbonded Post-Tensioning

This document discusses the advantages of post-tensioning slabs compared to reinforced concrete slabs. Post-tensioning slabs allows for larger column-free spans, faster floor-to-floor construction times of around 10 days per slab, and thinner slabs which reduce costs and increase seismic resistance. Additional advantages include earlier stripping of formwork below 10 days, reduced reinforcement and materials quantities, fewer workers required, potential for additional floors in height-restricted areas, reduced vertical structure costs, and greater flexibility for services, ceilings, and openings.Sustainability Advantage of Post-tensioning in Buildings

The University of Colorado Colorado Springs (UCCS)
needed more campus parking for the Alpine Village student
housing complex. In addition, the UCCS planning board
approved financing to expand their sporting complex.
This project served two purposes: a parking structure
that acted as a recreational field. The 1200-car, four-story
post-tensioned (PT) parking structure supported the
240 x 360 ft (73 x 110 m) artificial turf field on the roof

The high-rise building located at 111 W. Wacker Drive
in downtown Chicago, IL, was formerly known as the Waterview. The structure was originally designed as an 89-story luxury hotel located along the Chicago River. The construction of the conventionally-reinforced building progressed until the 27th floor, when it was shelved due to financing issues. In 2012, the hotel was redesigned as a 60-story residential apartment building and renamed OneEleven.OneEleven Tower - post tensioned transfer deck

The high-rise building located at 111 W. Wacker Drive in downtown Chicago was formerly known as the Waterview. The structure was originally designed as an 89-story luxury hotel located along the Chicago River. The construction of the conventionally-reinforced building progressed until the 27th floor when the 2007 economic recession hit the U.S. Ultimately, the original project was shelved due to financing issues. The unfinished building became a visible eye-sore in the heart of Chicago for several years. Fortunately, a consortium of creditors and lienholders (Clark Wacker LLC) took ownership of the project and formed a Joint Venture with Related Midwest in 2010.
In 2012, the hotel was redesigned as a 60-story residential apartment building and renamed OneEleven. There were several major design issues with converting a hotel into a 500-unit apartment with a smaller floor-plate and different column layout. Since the column were poured until the 28th floor, this floor was built as originally designed. The 29th floor was constructed with a 12-inch post-tensioned slab and functioned as an amenity level.
What separates this high-rise tower from others is the 60-inch transfer deck (located on the 30th floor). The transfer deck was designed to be a 72-inch conventionally-reinforced slab with the post-tensioned floors above. The PT Supplier and Concrete Contractor redesigned it into a 60-inch thick slab using post-tensioned to replace roughly 372 tons of rebar. The redesign saved around $380,000 from the cost of the transfer deck (excluding costs of other vertical elements). The reduced dead load of the slab also helped eliminate the reshoring requirements. The 12-inch building height reduction funneled into lower costs for all vertical elements and lower operational energy costs. A flat-plate was used in lieu of large beams and transfer girders in order to reduce forming costs.
The installation of the transfer slab and coordination of trades was extremely complex. Additionally, the coordination was fast-paced since the transfer slab was the second floor of the new construction. Construction trades and engineer spent almost one month on coordinating PT tendons, rebar and MEP piping/penetrations.
The transfer mat was poured in two lifts (20-inch and 40-inch lifts) for a total of roughly 2,250 cubic yards of 6000 psi concrete. One of the pours lasted 17 hours and had an increased degree of complexity due to being poured mid-air. In total, there was 60 tons of unbonded-post-tensioning (gross weight) used in the transfer deck.
The use of unbonded post-tensioning in the original design was also used to reduce the high-rise building height by at least 1 per floor as compared to mildly-reinforced concrete. PT helped make a stalled project more economical due to the reduction in material costs (concrete columns/walls, MEP piping, elevators/stairs and curtain-wall).Concrete International - Wayzata Bay Infrastructure

The One Museum Park West high-rise condominium tower in Chicago was originally designed with conventionally reinforced concrete slabs and transfer girders, but went over budget. A value engineering analysis proposed converting the structural design to unbonded post-tensioning, which would reduce costs by deleting some interior columns, transfer girders, and reducing girder depths. This option was chosen and resulted in $4 million in savings through reductions to concrete, rebar, forming costs, and other structure elements like caissons and walls. The post-tensioning supplier worked with the engineer of record to implement the new design, which increased PT usage from an initial 35,000 feet to 1.6 million feet and helped completePost Tensioning Review Session for Installers

Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands or bars, typically referred to as tendons. Post-tensioning applications include office and apartment buildings, parking structures, slabs-on-ground, bridges, sports stadiums, rock and soil anchors, and water-tanks.
