Overall “Excellence” Award Winner/First Place – Mid-Rise Structures

Chau Chak Wing Museum, Sydney, NSW, Australia. The Chau Chak Wing Museum at The University of Sydney is the culmination of many years of strategic planning that consolidates the University's Nicholson, Macleay, Power, and University Art collections and showcases some of Australia’s most significant artistic, scientific, and archaeological artifacts. With a specified design life of 100+ years, the aspiration for the Museum was to be as highly regarded as the iconic Great Hall and Quadrangle, the symbolic and ceremonial heart of the University. The construction of the museum involved bulk excavation, construction of a six‐level building (including a plant level and two basement levels) with 7740 m² (83,300 ft²) of gross floor area. The choice of concrete as construction material was simple. It enabled the structure and cladding to be one, making engineering efficient and construction seemingly straightforward. Delivered by FDC Construction, alongside JPW, Northrop, and Mahaffey Associates, this was an incredibly complex project. Numerous innovative and bespoke construction techniques were devised and adopted to create the Museum’s most striking feature—the large, floating, concrete “Box” perched atop its glass and sandstone podium. The “Box” is a complete in‐place construction that was limited in terms of placement breaks, deflection, and propping to ensure the utmost quality was achieved with limited cracking and deformation. The podium is an array of carefully placed concrete elements that were precast off site, with the structure then built over it. All aspects of the concrete construction were carefully considered, from prototyping, concrete mixture designs, reinforcement detailing, and post‐tensioning, through to pumping strategies. From the tinted, precast elements featured in the lower half of the building, to the ceiling of the entry level with all the cast‐in services, through to the cantilevered box itself, concrete features prominently, and yet is unobtrusively elegant. This timeless construction project will endure for generations to come, just as the University intended.

Second Place – Mid-Rise Structures

Denver Water Operations Complex Redevelopment – Administration Building, Denver, Colorado, USA. The Denver Water Administration Building is part of a 4‐year project that demolished 15 inefficient/obsolete buildings, renovated two, and constructed seven new structures. The Administration Building was in the final phase of the redevelopment, completed in late 2019. The building is six levels at 196,000 ft² (18,200 m²), constructed of post‐tensioned (PT) structural concrete. The exposed concrete slabs serve as the main heating and cooling element by radiating chilled water in the summer and hot water in the winter. At the time of construction, this was known to be the only structure in the United States with this design. The structural slabs are 9 in. (230 mm) thick, with 5/8 in. (16 mm) radiant tubing on 6 in. (152 mm) centers, 3/8 in. (9.5 mm) reinforcing bars in both directions, PT cables in both directions, and 1 in. (25 mm) electrical conduit all within the slab. The structure required a 4 in. (102 mm) expansion joint and two 22.5‐degree bends where all systems had to be overlapped. Mortenson constructed the building with zero lost-time accidents; 10,616 yd³ (8120 m³) of concrete; 8356 tons (7580 tonnes) of reinforcing bars; 2355 stud rails; and 391,764 ft (119,410 m) of PT tendons. Additionally, the project received LEED Platinum certification.

First Place – Low-Rise Structures

Chai Château Haut‐Bailly (Château Haut‐Bailly Winery), Léognan, Gironde, France. The renewed winery building for Haut‐Bailly, one of most famous Pessac‐Léognan properties in Bordeaux vineyard, should preserve the heritage of the existing buildings and combined vine/garden scenery of the estate. The new complex should yet efficiently house the vinification, ageing and storage cellars. Three major challenges were addressed: 1) integrate the new modern building into its landscape, fitting into the existing volumetric continuity and complex arrangement, while retaining the central image of the château. However, the functional aspect of the building required large volumes of space. This led to a circular building integrating an ascending landscape; 2) ensure structural efficiency of the 38 m (125 ft) span vault which dominates the vat room at a height of 8.8 m (29 ft), without posts, and supports a 2400 m² (25,830 ft²) hanging garden. The use of concrete makes this architectural feat possible and gives the building its timeless style. Concrete offers a plastic, sculptural, monolithic aspect that allows several aesthetics to be explored; and 3) manage the spatial approach, the visitors’ flow and sensory experience. The circulation is gentle because the shapes are soft, and contribute to the feeling of wellbeing that the building provides. The sensory memory of visitors should be marked by the place, just as it is marked by the estate’s wines. The feeling of expansion, compression and suspension provided by the architecture then resonates with what one experiences during a tasting. The project is organized around a circular vat room that allows for optimized integration of logistical movement. Discovering the winery from above, we overlook the grape harvest reception area from a footbridge. Then, reaching the vat room, the visitor physically perceives expansion of the vat room and then compression while passing between the vats. This movement gently makes an impression, just as wine can provide an array of sensations and memories during a tasting.

Second Place – Low-Rise Structures

Brossard Aquatic Complex, Brossard, Québec, Canada. The Multipurpose Centre was built in Polyaréna Park, more specifically between Antoine‐Brossard School and Michel‐Normandin Arena. Located in a residential sector, this park currently includes several sports facilities such as a skate park, tennis courts, and baseball and soccer fields. The construction of the Multipurpose Centre included two indoor pools: one 50 m (164 ft) long competition pool with 10 lanes as well as 1 to 5 meter high concrete diving platforms, and one recreational pool with 5 lanes, spray fountains, and a waterslide. The building houses the following related facilities: changing rooms, multipurpose rooms, conference room, sports club, mechanical rooms, stands, and a room for judges. The footprint of the building is approximately 5,350 m² and it is built over two stories. An elevator provides access to the second story. The building is a mixed concrete/steel construction, with a steel roof, a concrete story, and concrete pools. The project was completed using slightly more than 5,000 m³ of concrete. The floor on the second story is composed of unidirectional slabs on concrete beams, thereby allowing the point load of the stories columns to be cantilevered. The concrete story includes cast-in-place concrete stands cantilevered with respect to the main structure to give the impression that they are floating. The ground floor portion above the basement features a bidirectional slab on concrete columns, while the section without a basement features unidirectional slabs on concrete beams. Both pools are made from cast‐in‐place concrete. Since it is located in ground water, the building stands on a concrete bed on piles allowing a waterproof membrane to be installed.

First Place – High-Rise Structures

100 Above the Park, St. Louis, Missouri, USA. One Hundred Above the Park is a thirty‐six story, 316‐unit residential tower located on the northeast corner of historic Forest Park in St. Louis, Missouri. One Hundred makes a bold statement on the skyline, featuring unique geometry and a sloping curtain wall façade designed by Jeanne Gang and Studio Gang Architects. The sloping façade was constructed using leaf‐shaped floor plates with jagged edges and angles around the perimeter. Each successive floor steps outward in a series of stacked 4 and 5 floor tiers forming the slope of the exterior curtain wall. The top floor in each tier creates a balcony for the first floor of the next tier connecting residents to the outdoors. The visionary design was achieved using a post‐tensioned concrete frame and central core to support the cantilevered floors of each tier. The resulting building shape is both beautiful and energy efficient. The geometry of the floor plate allows for multi‐directional views and an abundance of natural light through a 90‐degree corner in each living room. The unique sloping façade reduces solar heat gain and promotes stunning views of Forest Park to the west and the Gateway Arch to the east. The building also provides storefront retail space on the ground floor, an enclosed parking garage, and an amenity floor with a fitness center, patio deck, and swimming pool. Residential spaces are offered at varying sizes and include luxurious interior finishes and floor‐to‐ceiling windows in every unit. One Hundred Above the Park has re‐defined the St. Louis skyline to the west and will promote further development in the surrounding Central West End neighborhood. This project is iconic for the city of St. Louis; a city rich with history and stunning architecture.

Second Place – High-Rise Structures

Faria Lima Plaza, São Paulo, Brazil. The Faria Lima Plaza building represents a modern and innovative project, and it stands out mainly due to its differentiated architecture. The building is approximately 110 m (360 ft) high and has sloping pillars that change its direction along its length. The architectural concept of the project is based on two forms that intertwine with each other in an elegant and dynamic way, as in a dance. The bold architecture required high‐level engineering to be successfully built, considering not only the technical challenges of the project, but also the logistical difficulties of constructing a building of this size in a very busy region in São Paulo city. The building also obtained LEED Gold precertification, confirming a sustainable, efficient, and economical structure, with principles of smart growth and green construction. The study of the concrete was focused on obtaining optimized mixture designs with reduction of cement content and of CO₂ emissions into the atmosphere, also contributing to obtain a more sustainable construction. The structural solution for the foundation forecasted the construction of a combined footing with a volume of 1400 m³ (1830 yd³) of concrete and 3 m (10 ft) in height and required detailed thermal studies to define the concreting plan and the fresh concrete precooling levels. The inclined pillars designed by the architect made it necessary to perform several concrete tests, including creep tests for different concrete mixture designs. There is no record of another building project in Brazil for which this test was done. Faria Lima Plaza has already become a symbol among the many skyscrapers in São Paulo and has a huge potential to become an architectural and high‐level engineering reference in the largest city of South America.

First Place – Decorative Concrete

Aquatic Gallery, Ahmedabad, Gujarat, India. The Aquatic Gallery—India’s largest public aquarium—is a part of the Science City campus located in Ahmedabad, Gujarat, India. It serves as a platform to raise public awareness on the precious water world with its display of various species of fish. The facility is set up across 2.5 acres, and with a built‐up area of ~150,000 ft², merges science education with entertainment. Shapoorji Pallonji and Company Private Limited (SPCPL) was the General Contractor for this project. It was inaugurated on July 16, 2021. The building, designed as a shell, is symbolic of the aquatic life. The frame structure of the building is entirely in concrete, except the central atrium roof truss. The Aquarium, having 80.5-degree inclined conical exposed reinforced concrete (RC) walls with heights varying from 9.4 to 13.9 m (31 to 46 ft), forms a shell-like structure. Spread across four floors, the Gallery houses 72 exhibit tanks. The building consists of reinforced colored concrete exposed walls with Class F3 finishes. It is divided into seven segments and each segment is topped with an inclined slab with all corners at different elevations. The geometric design of the RC structure involved higher formwork material consumption and additional labor effort. The walls had many horizontal and vertical grooves that posed challenges in the formwork and concreting. The circular columns were cast using plastic formwork, and the curved walls were cast using customized aluminum formwork. The building elevation has curved fins with 3D‐slope matching the form‐finished walls in look and feel and durability for the operation phase of the structure. The project involved extensive high‐end architectural finishes, which required careful attention to detail and meticulous execution to achieve quality. SPCPL used building information modeling (BIM) to visualize the design details, avoid clashes between various services, and generate coordinated shop drawings.

Second Place – Decorative Concrete

Hollywood Park NFL Media Building, Inglewood, California, USA. The Hollywood Park NFL Media Building is a 450,000 ft² (41,800 m²) Class A office building comprising an eight‐story high‐rise tower with a rooftop mechanical penthouse, a partial basement, and a two‐story studio support base that includes a high‐bay studio building housing five broadcast studios. The form of the office building is derived directly from the unique character of its setting within the masterplan’s Sports and Entertainment District and an intentional relationship to the neighboring SoFi Stadium, resulting in a skewed parallelogram composed of two elegantly curving facades that culminate into two acutely pointed and visually powerful building angles. The upper mass of the tower in defined by a white glass fiber-reinforced concrete (GFRC) envelope with repetitive openings to provide uniform views and daylight for the open‐office functions within, with windows deeply recessed to provide optimized shading. The envelope is further enhanced with curving ribbon windows and glazed balconies strategically incised into the GFRC’s monolithic massing. Below the GFRC envelope is a dark gray cast‐in‐place shotcrete base that, being more solid, reflects the reduced daylight requirements of the broadcast functions within. The architectural concrete base wraps the entire façade to serve as a plinth upon which the white mass above lightly sits. Windows and building entries are carved deep into the solid concrete mass. The northeast façade boasts a ribbon window that stretches several hundred feet offering direct and unobstructed views onto the Stadium and Gameday Plaza. While the typical floor height of the office building is a generous 13 ft‐6 in., the plinth provides a 20 ft‐6 in. high‐span volume at ground level, highlighting the monumental nature of the architectural concrete as it turns into the sidewalls of the main lobby interior. The architectural concrete—through its rich character and visual presence—is the foundational material for the design concept.

First Place – Infrastructure

SCG‐CPAC Ultra‐High-Performance Concrete Bridge, Bang Sue, Bangkok, Thailand. In 2021, the first post‐tensioned ultra-high-performance concrete (UHPC) bridge in Thailand was erected at the SCG Headquarters in Bangkok. The concept of architectural design was a challenging low arch‐shape with a limited height at midspan of no larger than about 1.25 m (4 ft), while the span length was approximately 28 m (92 ft). Based on a small height‐to‐span ratio, the foundation on both sides had to carry extremely high-lateral forces from arching action. To overcome both architectural and engineering barriers, the “architecturally” arch bridge was redesigned by using two cantilever curved girders extending horizontally from each side of abutment. Therefore, the horizontal forces acting on both abutments were eliminated. However, as such long cantilever beams, both girders must resist high-bending moment, while slender beams are more desirable from the architectural point of view. The bridge was designed to carry a live load of 500 kgf/m² (100 lbf/ft²). Both girders had a tapered shape, where the minimum thickness at the tip end was 0.30 m (1 ft). To maximize the moment capacity, SCG‐UHPC material with a 150 MPa (21,755 psi) compressive strength and a capability to resist high-tensile and shear stresses was used for manufacturing the girders. The high-range water-reducing admixture used in the mixture was polycarboxylate ether-based, which was developed in‐house by the Research and Innovation Center of SCG Cement. After installation, the tendons were inserted from the tip‐end of individual beam, through the corrugated steel ducts inside the beam, and eventually footing. Thereafter, tendons were stressed with hydraulic jacks at the back side of the foundation. Due to a high flexural strength and a flexural hardening behaviors of UHPC, none of reinforcing bar was used in thin slab decks which had a thickness between 25 to 75 mm. With these superior performances aforementioned, UHPC offers the next breakthrough technology in the construction industry.

Second Place – Infrastructure

Rose Fitzgerald Kennedy Bridge, New Ross, Wexford, Ireland. The 887 m (2910 ft) long, nine‐span Rose Fitzgerald Kennedy (RFK) Bridge over the River Barrow includes a three‐tower extradosed bridge with two equal 230 m (755 ft) long main spans. The structure is impressive in scale and slenderness. It holds multiple records, including the longest concrete extradosed spans in the world and, during construction, the longest balanced cantilever for concrete deck extradosed bridges in the world. The three towers have different heights; the central tower is slightly higher but only 27 m (89 ft) high and 16 m (52 ft) for the lateral ones, while the deck has deck slenderness of L/65 at midspan, L/35 at the lateral towers, and L/27 at the central support. Proportioned to the golden ratio in height and span distribution, with a truly shallow single central plane of cables in a harp arrangement with cable numbers proportional to the tower, the bridge blends into the gentle hilly landscape of southeast Ireland, minimizing the visual and environmental impact on the Barrow. Its asymmetry and slenderness provide an iconic distinctive profile that has become already a symbol of engineering ingenuity. The deck, a single box with the appearance of a closed cross section, blending cast-in-place and precast elements, consciously designed as a full concrete deck to minimize maintenance, carries a dual motorway and ensures safe fluvial ship traffic crossing the river with a vertical clearance of 36 m (118 ft). As the River Barrow is a candidate Special Area of Conservation (SAC), due to rare habitats and species, and the River Barrow Estuary is a proposed Natural Heritage Area, careful consideration was given to the design of the scheme to ensure that it is sensitive to its surroundings. The design and construction of this bridge in the southeast Ireland required world‐class consultancy services in bridge and civil engineering and has redefined the expectations for bridge engineering, both nationally and internationally.

SoFi Stadium, Inglewood, California, USA. The sheer size of this project is notable. Nothing this large has ever been developed in the Los Angeles decorative concrete market, comprising over 720,000 ft² (66,890 m²) of decorative paving. Everything on this project was on a whole other scale, stretching decorative concrete flatwork placements to 300 yd³ (229 m³) a day back-to-back while maintaining consistent surface-retarder finishes. The stadium roof structure anchors to the ground at three locations around the site called the abutments; at each abutment location, Trademark built unique 14 ft (4 m) walls with batters ranging from 11 to 39 degrees and a surface-retarder finish. Most of the vertical elements around the site did not consist of a 90-degree vertical face; most walls used custom-cut foam to achieve custom batters and radiuses. The 6 in. (152 mm) planter curbs transitioned using foam to 18 in. (457 mm) tall battered seat walls while maintaining a surface-retarder finish. Every vertical wall on the site had a surface-retarder finish, meaning every wall had to be stripped and hand-finished to achieve the design team’s intent. Trademark detailers spent over 2400 hours detailing every site element to support the field with this project. All survey and layout was based off Trademark shop drawings.

First Place – Repair and Restoration

The Corniche Kennedy, Marseille, Bouches-du-Rhône, France. The Corniche Kennedy is an iconic road in the city of Marseille that runs along the Mediterranean Sea. It was widened in the 1960s to create a pedestrian promenade of 1.7 km (1 mile) corbelled over the sea. Renamed Corniche du Président John Fitzgerald Kennedy in 1963, the structure is made up of 384 corbels anchored in a retaining wall or in crossing structures, spaced every 4 m (13 ft), on which slabs rest. The superstructure consists of two sidewalks separated by a bench, known as “the longest in the world,” and a parapet. After 60 years of exposure to sea spray and splashing waves, many sections were distressed. The owner, Métropole Aix Marseille Provence, undertook a vast rehabilitation operation. The work consisted of reinforcing or replacing the structural elements according to their state of deterioration. As the structure is located near the Maregraphe, a listed monument, the new benches and parapets were designed in agreement with the architect of the Bâtiments de France Architectural restorations were done on the shape of the parapet. It was designed to meet the height standards while preserving the shadow of the existing. During the preparation period, several elements were submitted for the architect's to choose the perfect color. The location of the structure, between busy traffic lanes on one side and the sea and rocks on the other, required the adaptation of the traffic road and the development of a soft lane. Special means of access were used: a rolling negative platform, scaffolding anchored to the retaining walls, and a negative bucket truck. After four phases of work that started in 2018, the Corniche John Fitzgerald Kennedy was reopened to the public in spring 2022.
