Pegasus Engineering Whether it is sports stadiums, hospital buildings, factories, or heritage buildings Pegasus Engineering has the skills and experience to complete all structural steel work to the highest standard. Pegasus Engineering’s excellent skills were recently recognised in the 2022 Steel Construction New Zealand awards, where it was a finalist for its work on the Upper Village project in Queenstown. Brett Dodds, a project manager with Pegasus Engineering, says the build was challenging in a number of ways, but with careful sequencing and planning the build came together seamlessly. On the Upper Village project Pegasus Engineering was engaged to provide around 209 tonnes of structural steel across the two buildings which make up the two-level shopping complex. The buildings consist of structural and architectural steel with a mixture of moment frames, braced frames, and cantilever and canopy sections. The canopy sections slotted in and around precast concrete, which made it an interesting project for Pegasus Engineering to fabricate, transport and erect. Brett Dodds says the project involved a lot of architectural metalwork, in the form of overhanging glass canopies which took a lot of coordination to get in and erected on site and looking good. The building was designed by BSPN, and the structural engineering by ENGCO. The main contractor was Cook Brothers Construction, who contracted Pegasus Engineering to supply and erect the structural steel. The Upper Village building is in the heart of Queenstown, on an elevated site with impressive views out over the CBD, Lake Wakatipu and The Remarkables off in the distance. But that spectacular site presented one of the challenges for the Pegasus Engineering team who had to navigating up Queenstown’s hilly narrow roads with their large trucks and trailers to deliver the various oversized components. The crane position and laydown areas were also very limited, so deliveries had to be carefully coordinated to make the most of the available room. Brett says the coordination between Cook Brothers and Pegasus Engineering was paramount to make sure they could have the right workflow. Steel Construction New Zealand (SCNZ) has announced the winners in the 2022 SCNZ Excellence in Steel Awards - which celebrate the sector’s commitment to innovation, best practice and collaboration. SCNZ chair David Moore said the high calibre of projects presented at the awards was a reflection of the skills, experience and commitment of our industry’s people. “It’s what sets our local structural steel sector apart from the rest of the world, which is so important in a post-COVID environment when local expertise continue to be in high demand.” The 2022 winners are: Supreme Winner and $1.5M-$3M category winner: D&H Steel Construction for NL2A Shared Pathway Steel features heavily in the Shared Path, which follows the geometry of the existing KiwiRail tracks. The pathway comprises several different steel applications including elevated helical boardwalks, balustrades and handrails, and a new pedestrian bridge. Sited over rough terrain and waterways, D&H Steel provided value engineering to make the 2.9km mostly off-road pathway buildable and practicable. Under $500K category: John Jones Steel for Te Aika Sculpture The sculpture, which is 8m high and 10m wide, was fabricated in one piece to ensure it was symmetrical before being split apart for transport and painting. Designed by two Ngāi Tahu artists, it will sit on the Avon riverbank and form a ngutu, or entranceway, to the Te Pae convention centre in Christchurch. $500K-$1.5M: John Jones Steel for the Ōtākaro Avon River Corridor Bridges The three architecturally designed bridges that cross the Avon River in Medway, Avondale and Snell, are an important feature in the area’s regeneration. To achieve the desired look, the hollow steel sections were induction bent and an anti-graffiti, UV-resistant topcoat of paint was applied. The 45m-long, 4.5m-high, 3m-wide bridges were trial assembled in John Jones Steel’s workshop to ensure accuracy before being seamlessly installed. Over $3M: Aurecon and D&H Steel Construction for Puhinui Station Interchange Puhinui interchange is a striking transport hub that supports the shift to low-carbon transport options. The steel structure was driven by bold architectural requirements, which included complex structures like curved welded beams, V-shape columns, three-dimensional trusses and difficult connection geometries. Earthquake Strengthening: Petone Engineering for Generator – Waring Taylor The façade of this heritage building in Wellington has been retained and character features including exposed structural steel, timber and brickwork have been incorporated into the design. Strengthening work brought the structure up to 100 percent of the New Building Standard and involved adding new five-storey shear walls and a full-height structural steel K-frame. The new skeleton preserves the original 1920’s steelwork and adds substantial strength in a visually appealing way. Standalone Residential: VIP Structural Steel for Rocking Horse Road The home’s design references Christchurch buildings of the 1960s with its use of embossed blockwork and structural steel. The external spiral staircase and internal floating stairs are the main structural features of this build and could only be achieved using steel. Both staircases were completely assembled off site and transported as one. The home’s design has resulted in a smart structure to overcome the challenges of building in a floodplain. “It was a mixture of structural steel and precast concrete and in-situ poured concrete, so there was a lot of coordination between the companies to make it a successful project. “The main thing was the sequence of how the building was erected to allow it to be built. “There’s overhanging canopies and they couldn’t be installed until other parts of the building were erected. The sequencing was really important on this one.” The Pegasus Engineering team installed the many architectural canopies and facades clockwise on the way around the building, as the builders were installing precast panels and in-situ concrete floors. The finished project brings together wood, glass, and steel to add another impressive building to the ever-growing Queenstown. Pegasus Engineering works throughout the South Island and has been involved in many of the area’s most significant buildings. These include the Forsyth Barr Stadium in Dunedin, the new Outpatients Building at Christchurch Hospital and restoration work on Christchurch’s historic Isaac Theatre Royal. Brett says Pegasus Engineering always ensures it keeps up with the latest technology to make sure they are always at the forefront of innovation. This includes ensuring they can offer quality assurance and full traceability on all of their materials. “We can trace exactly where every piece of material was manufactured, in terms of when the stock material was made overseas, and we can trace it right through to the end product in the building.” In addition to fabricating all it is own materials at its Rolleston site, Pegasus Engineering also do all its own detailing, painting, delivery, and erection on site. Brett says it is all just part of Pegasus Engineering ensuring that every job is done well and done to its exacting high standard. “It was a mixture of structural steel and precast concrete and in-situ poured concrete, so there was a lot of coordination between the companies to make it a successful project.” Proud to supply quality welding wires and machines to Pegasus Engineering Ltd Ph 09 634 1949 | www.weldingengineers.co.nz LORCH 500 Amp MicorMIG • Up to30%fasterwelding speeds • Designed for ease of use • Futureproof, upgradeable with Paywave • 100%German manufacture, quality assured • Industry 4.0 capability Proud to support Steel Construction New Zealand
