ACI Excellence in Concrete Construction Award Winner

Overall “Excellence” Award Winner/First Place – Category: Decorative Concrete

 

Palazzo Italia (Italian Pavilion Expo 2015). Milan, Italy. The Italian Pavilion is the throbbing heart of Expo 2015. The architectural design envisages the construction of a complex structure whose exterior and some interior spaces recall the shapes of branches in a thick forest. The entire outdoor surface and part of the interiors consist of i.active BIODYNAMIC cement panels, obtained using Styl- Comp technology from the new material developed at i.lab, the heart of Italcementi’s research and innovation. The “bio” component is given by the product’s photocatalytic properties, originating from the active ingredient TX Active, patented by Italcementi. In direct sunlight, the active principle contained in the material “captures” certain pollutants present in the air and converts them into inert salts, helping to purify the atmosphere from smog. The “dynamic” component is a specific characteristic of the new material, whose particular fluidity allows the creation of complex shapes like those found in the Palazzo Italia panels.

Description of Project and Project Demographics: Project Size: 13,000 m², 2500 tons biodynamic cement, Construction Duration: 10 months

Project Team Members: Owner: Expo 2015 spa; Architect: Nemesi & Partners srl; Engineering Firm: Bms progetti srl and Proger Spa; General Contractor: Italiana Costruzioni; Concrete Contractor: Styl-Comp; Concrete Supplier: Italcementi.

First Place – Repair and Restoration

 

The Strand, American Conservatory Theater (A.C.T.) San Francisco, CA. The transformation of an abandoned, century-old movie theater into a highly visible, alternative, experimental performance space for San Francisco’s preeminent theater company is a major milestone in the regeneration of the midsection of Market Street. The new structural system consists of a metal deck roof diaphragm over the original auditorium trusses, ductile reinforced concrete and reinforced masonry shear walls integrated with the spatial expression of the interior spaces, and a mixture of reinforced concrete slabs and beams and steel and composite metal deck floor framing all supported on new, shallow reinforced concrete foundations and grade beams. Useable area was created for actors’ changing rooms and other support functions by excavating to create a reinforced concrete basement structure below the stage between existing foundations. The project team worked closely with historic preservation architects to retain and reuse as many of the original materials and features as possible, including the masonry façade and internal finishes. To restore the façade, decorative glass fiber-reinforced concrete panels were cast from molds made from the existing relief and installed below the building’s canopy to extend the ornamentation to the ground.

Brisbane West Well Camp Airport (BWWA) EFC Geopolymer Pavements. Wellcamp, Queensland, Australia. Brisbane West Wellcamp Airport (BWWA) is Australia’s first public airport to be built in 48 years. BWWA opened on November 11, 2014, marking a very significant milestone in engineering: the world’s largest modern geopolymer concrete project. Construction of the heavy-duty 435 mm thick aircraft pavements at BWWA was undertaken using a geopolymer concrete that contained absolutely no portland cement. The finished pavements are now in service and provide an excellent example of achieving massive environmental improvement with concrete without compromise on strength, durability, or cost. Achieving an exemplary environmental outcome along with cost competitiveness, durability, and structural performance were key criteria of the project brief. The environmental benefit of EFC is achieved through the replacement of carbon-intensive portland cement with two major recycled wastes from industry—blast furnace slag from steel production and fly ash from coal-fired power generation.

Description of Project and Project Demographics: Project Size: 50,500 m², 45,560 tons of concrete, Construction Duration: 4 months

Stealth. Atlanta, GA. Stealth is a contemporary urban sculpture. The monolithic cast-in-place reinforced concrete form stands 33 ft tall in the plaza of the Promenade Tower in the Arts District of Midtown Atlanta. The piece is a spatial work of cognition, illusion, and transformation. The sculpture acts as an urban instrument, binding neighboring spaces through visual corridors. The sculpture was analyzed with SAP finite element program, using a generated mesh and varying thicknesses of elements to simulate the elliptical cross section of the sculpture. The upper portion is 7 in. thick and is dominated by shell behavior with relatively low stresses and is reinforced with a two-way mat of No. 5 reinforcing bars at 4 in. on center. The lower portion is 14 in. thick and is dominated by bending behavior with high stresses resisted by two No. 7 reinforcing bars at 4 in. on center vertically with No. 5 horizontal ties at 4 in. on center. The structure is founded on a 16 in. thick mat foundation to support its 65,000 lb weight and resist overturning wind loads.

First Place – Category: Low Rise Buildings

 

Museo Internacional del Barroco. Puebla, Mexico. Three main concepts have been addressed while designing the museum: one—from a rigid order, space melts and creates fluid spaces; two: beautiful light; and three: an ecological mechanism and the care of the environment. Conceptually, it is imagined that the building flows out from the land as a spring and grows. The structure was based on a system of apparent white concrete prefabricated walls and smooth finish acid, with the purpose to finish quickly, deleting the process of casting and curing concrete, and reduce labor with little investment in equipment. A challenge was to get the aesthetic finish—which was intended to be perfect, unblemished, and homogeneous in appearance—for which steel formwork were used with an exhaustive control of joints between pieces.

McCord Hall at ASU W.P. Carey School of Business. Tempe, AZ. The W.P. Carey School of Business added a new state-of-the-art building to their current facilities on Arizona State University’s Tempe campus. McCord Hall is the new home for the graduate, MBA, and Executive Education programs. A monumental four-story concrete arcade frames the entrance to the school from both sides of the campus at the northeast corner, while to the southwest, the plaza opens up to welcome visitors and the business school community. McCord Hall is designed to be a reusable structure that can be re-purposed without having to be demolished for up to 100 years and possibly longer. Each building has a unique post-tensioned solution that consisted of a two-way flat plate design for the north building and a one-way slab with shallow dropped beams at each radial grid on the south building. The buildings were linked at each floor with a long-span open skyway constructed with radiused cast-in-place concrete T-beams supported on haunches at the expansion joint. The lateral system consisted of intermediate concrete shear walls which were designed using the simplified analytical method and redesigned using dynamic analysis procedures, which resulted in the removal of one wall from the first floor to the roof and reduced the overall cost of the lateral system by 15%.

Viktoria. Seattle, WA. The Mission Bridge is a major four-lane, 1-km long crossing of the Fraser River in British Columbia, Canada. It was opened to traffic in 1973. The bridge is located in a high seismic zone and is a critical lifeline link in the Province’s disaster recovery network. The crossing is one of the nine major crossings prioritized for seismic retrofit, spurred in large part by the 1989 Loma Prieta earthquake in San Francisco. This project exploited the unique properties of UHPC to solve a significant challenge in the seismic retrofit of large concrete columns. A novel UHPC column jacket as a seismic retrofit was a critical last step in this retrofit project.

The "Ring of Memory" International Memorial of Notre-Dame-de-Lorette. Ablain-Saint-Nazaire, Paris, France. The "Ring of Memory" International Memorial has been built to celebrate the first World War Centennial at the very place of one of its most murderous battlefields near Arras (Northern France), close to the largest French War Cemetery on the crest dedicated to Notre-Dame de Lorette. The International Memorial is an outstanding architectural achievement, but it is also a technical challenge. The Ring is composed of two distinct structures. The first one consists of standard precast segments with thin walls (4 cm thick), resting directly on the ground. The second is a three-span curved bridge, 125 m in length with a main span of 56 m, realized using precast segments assembled by post-tensioning. Indeed, its very particular geometry is associated with very high flexural-torsional stresses. Only ultra-high-performance fiber-reinforced concrete, namely the BSI® (Béton Spécial Industriel) developed by Eiffage Group, made it possible to meet the special structural, durability, and architectural requirements to create this impressive fence favoring meditation.

3rd Bosphorus Project. Istanbul, Turkey. Eight lanes of motorway and two lanes of railway will be located at the same level on the 3rd Bosphorus Bridge. A bridge of firsts, the 3rd Bosphorus Bridge is going to be the widest suspension bridge in the world with a width of 59 m and the longest spanning bridge that has a rail system on it, with a main span of 1408 m. Another first for the bridge is that it is the suspension bridge with the highest tower in the world, with a height of more than 322 m. The tower structures are built with reinforced concrete up to a height of 305 m, and the rest is a steel saddle for main cables. The compressive strength of the concrete used in the project is classified as C50/60 and it fulfils various durability requirements because it needs to provide at least 100 years of service life under rough environmental conditions. Including foundations, 104,000 m³ of concrete was used for the construction of the four pylons of the bridge.
