LONG SPAN STRUCTURES C H I N Q U I H U E S TA D I U M CASE STUDY CHINQUIHUE STADIUM ARCHITECTS: CRISTIAN FERNANDEZ ARQUITECTOS YEAR: 2013 MANUFACTURERS: ARMSTRONG CEILINGS, HUNTER DOUGLAS, LINEA OFFICE ETERSOL, METECNO, POLYTAN THIS PROJECT IS CONCEIVED FROM THE LOGIC OF A CONSTRUCTIVE, MODULAR AND PREFABRICATED SYSTEM, SUITABLE TO BUILD THE PROJECT IN PHASES. THEY ARE CLAD IN ALUMINUM PANELS, OPAQUE OR MICROPERFORATED, GENERATING OPAQUE OR SEMI TRANSPARENT PLANES. THE ENTIRE SYSTEM OF NEW BLEACHERS IS DESIGNED BASED ON PRECAST REINFORCED CONCRETE ELEMENTS, MOUNTED ON PREFABRICATED COLUMNS AND BEAMS OR ON A FEW ELEMENTS MANUFACTURED ON SITE. THE GALVANIZED METAL TRUSSES ARE REPEATED RHYTHMICALLY, SETTING THE CLOAK THAT COVERS THE STADIUM. THERE IS A STRONG FORMAL ANALOGY BETWEEN THE CONSTRUCTIVE METHOD OF THE STADIUM AND THE CONSTRUCTION OF BOATS ... THE ROOF, STRUCTURED BASED ON TRUSSES, AND ENVELOPE OF THE STADIUM, ARE IN THE CONSTRUCTIVE LOGIC OF A BOAT, WITH ITS RIBS, FRAMES AND PLATING. AMENITIES 2 GENERALLY SPEAKING, A HIGH PERCENTAGE OF WHAT IS BUILT IS MODULAR, REPETITIVE AND PREFABRICATED, WITH LOCAL CHILEAN MATERIALS AND ENGINEERING, MAKING IT FEASIBLE AND REALISTIC TO KEEP THE PROJECT WITHIN THE PROPOSED COST AND SCHEDULE. A STADIUM WITH CHARACTERISTICS THAT EMBODY THE IDENTITY AND CREATE A STRONG IMAGE TO PUERTO MONTT. CHINQUILLUE STADIUM IS SET ON THE EDGE OF THE CANAL AND OPPOSITE THE ISLAND OF TENGLO. THIS SITE PROVIDES THE STADIUM WITH A PRIVILEGED VIEW, THIS BECOMES A PARTICULAR AND UNIQUE FEATURE, WHICH IS ALREADY PART OF THE IDIOSYNCRASY OF THE CURRENT STADIUM. THE ELLIPTICAL DESIGN OF THE NEW PROJECT MAKES A GESTURE OF OPENNESS TO THE LANDSCAPE, AS THE EAVES IN THE ACCESS AREA ACROSS THE STREET, WHICH CLOSE THIS GREAT FIGURE, ARE AT A LEVEL BELOW THE VIEWING ANGLE FROM THE BLEACHERS, ALLOWING A CLEAR AND FRAMED VIEW OF THE CHANNEL AND THE ISLAND. AMENITIES 3 THUS, BESIDES MEETING ALL THE PROGRAMMATIC AND FUNCTIONAL REQUIREMENTS, THE MORPHOLOGY OF THE NEW STADIUM FRAMES ITS PRIVILEGED VIEW OF THE CANAL, AND GIVES THE CITY AN EMBLEMATIC BUILDING THAT ACCENTUATES THE PUERTO MONTT IDENTITY. A BUILDING THAT MEETS IN A CLEAR MANNER, THE PROGRAMMATIC AND FUNCTIONAL REQUIREMENTS OF THE COMMISSION. FROM OUR PERSPECTIVE, IT IS FEASIBLE TO PARTIALLY REDUCE THE REQUIREMENTS AND AREAS FOR THIS STADIUM WITH A CAPACITY OF 10,000 IN THE LOGIC OF A DESIGN COMPETITION, WHAT MATTERS AT THIS STAGE IN RELATION TO THE PROGRAM AND ITS FUNCTIONAL ASPECTS, IS TO GIVE A SIMPLE AND CLEAR STRUCTURE TO THE BUILDING, WHICH HAS THE POTENTIAL TO RECEIVE THE INEVITABLE AND NECESSARY AMENDMENTS AND ADJUSTMENTS TO THE ORIGINAL PROGRAM..THE PROGRAM IS STRUCTURED IN THREE LEVELS; COURT LEVEL, BLEACHERS LEVEL AND ABOVE BLEACHERS LEVEL, IN ADDITION TO DISTINGUISHING THE CENTRAL OR NEUTRAL SECTORS, AND THOSE FOR DIFFERENT TEAMS. AMENITIES 4 THE CLOSED AND ELLIPTIC FORM PROPOSED IN OUR DESIGN ALLOWS THE BUILDING TO LEAN STUNNINGLY TOWARDS THE AVENUE, WITH A LARGE HORIZONTAL FACADE, DISPLAYING THE NEW STADIUM AND MAKING IT MORE TRANSPARENT.THIS MEETING POINT BETWEEN THE STADIUM AND THE STREET BECOMES THE MAIN ACCESS, BOTH VEHICULAR AND PEDESTRIAN, TO THE SITE. THIS GIVES THE STADIUM A NASCENT URBAN AND SYMBOLIC PRESENCE FOR THE ENTIRE CITY OF PUERTO MONTT.THE 90° ROTATION OF THE TRUSSES GENERATES A PROTECTIVE OVERHANG IN THE ACCESS, AND A LONG FACADE WHERE THE PUBLIC ACCESSES AND TICKET OFFICES ARE LOCATED.
