L\u2019h\u00f4pital cantonal d\u2019Aarau (KSA) est l\u2019un des plus grands centres hospitaliers en Suisse. Le b\u00e2timent neuf sur le terrain existant est le fruit, d\u2019une d\u00e9cision prise, en 2019 et garantira, \u00e0 partir de 2027, la conformit\u00e9 continue de l\u2019h\u00f4pital aux hautes exigences de l\u2019encadrement m\u00e9dical. Construit selon la norme Minergie P Eco, il est form\u00e9 d\u2019un socle \u00e0 quatre \u00e9tages, sur lequel a \u00e9t\u00e9 \u00e9tablie, une structure d\u00e9cal\u00e9e vers l\u2019int\u00e9rieur haute de six \u00e9tages. Le b\u00e2timent est plac\u00e9 au sein d\u2019un vaste espace de stationnement.<\/p>\n\n\n\n

Le nouvel h\u00f4pital couvre une surface de plancher totale de 110 000 m\u00b2, abrite 472 lits stationnaires et 18 blocs op\u00e9ratoires. Les zones ambulatoires, stationnaires et d\u2019intervention, avec leurs flux de circulation, sont clairement s\u00e9par\u00e9es par un boulevard \u00e0 quatre \u00e9tages, inond\u00e9 de lumi\u00e8re. Celui-ci constitue le coeur du b\u00e2timent et facilite l\u2019orientation des patientes et patients, des visiteurs et du personnel.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Un partenariat \u00e9prouv\u00e9 pour le projet int\u00e9gr\u00e9<\/h2>\n\n\n\n

L\u2019ancienne BAM Swiss AG, reprise en 2021 par Implenia Suisse SA, a oeuvr\u00e9 comme entreprise totale. D\u00e8s la phase d\u2019appel d\u2019offres pour le projet int\u00e9gr\u00e9, H\u00e4lg Group s\u2019est vu confier la conduite globale dans le domaine de la ventilation, de la climatisation<\/a>, du chauffage, et du froid<\/a>. Le partenariat \u00e9tait d\u00e9j\u00e0 concluant dans d\u2019autres projets, par exemple pour l\u2019h\u00f4pital Felix Platter \u00e0 B\u00e2le, et s\u2019est poursuivi avec succ\u00e8s sous le toit d\u2019Implenia Suisse SA. Les succursales d\u2019Aarau et de Zurich \u00e9taient impliqu\u00e9es dans le projet. Pour la premi\u00e8re fois, un chef de projet global a assur\u00e9 du c\u00f4t\u00e9<\/a> de H\u00e4lg Group la coordination des travaux au sein d\u2019un consortium avec Implenia Suisse SA.<\/p>\n\n\n\n

\n

\u00abTraiter un projet aussi grand et complexe dans les d\u00e9lais, avec une haute qualit\u00e9 et conform\u00e9ment
aux co\u00fbts convenus est vraiment exceptionnel. H\u00e4lg et Implenia y sont parvenus en partenariat.\u00bb<\/strong><\/p>\nJochen Dietmeier, directeur Construction de laboratoires et d\u2019\u00e9tablissements de sant\u00e9 chez Implenia Suisse SA, Division Buildings<\/cite><\/blockquote>\n\n\n\n

Ventilation et climatisation exigeantes pour l\u2019h\u00f4pital<\/h2>\n\n\n\n
\"L\u00fcftungsanlagen<\/figure>\n\n\n\n

H\u00e4lg & Cie SA Aarau<\/a> a r\u00e9alis\u00e9 la ventilation et la climatisation. Le traitement de l\u2019air s\u2019effectue par plusieurs appareils de ventilation, regroup\u00e9s selon l\u2019affectation en installations autonomes. Les affectations principales englobent les domaines suivants: op\u00e9rations, processus, gastronomie et zones g\u00e9n\u00e9rales. Le syst\u00e8me de ventilation doit r\u00e9pondre \u00e0 de tr\u00e8s hautes exigences dans les blocs op\u00e9ratoires. Dans ces locaux sont mont\u00e9s des plafonds \u00e0 flux laminaire qui produisent un courant de refoulement \u00e0 faible turbulence. Ils cr\u00e9ent une zone de protection st\u00e9rile au-dessus du champ op\u00e9ratoire et refoulent les germes. Les blocs op\u00e9ratoires sont \u00e9quip\u00e9s de monoblocs s\u00e9par\u00e9s pour l\u2019air fourni et l\u2019air vici\u00e9. Des rapports cibl\u00e9s de surpression et de d\u00e9pression emp\u00eachent des transmissions d\u2019odeurs dans les zones sensibles.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Alimentation d\u2019\u00e9nergie efficace pour la chaleur et le froid<\/h2>\n\n\n\n
\"Heizung<\/figure>\n\n\n\n

H\u00e4lg & Cie SA Zurich<\/a> a r\u00e9alis\u00e9 les installations de chauffage et de froid. Ses prestations comprenaient notamment l\u2019ex\u00e9cution de la centrale d\u2019\u00e9nergie pour l\u2019alimentation en chaleur et en froid \u00e0 partir de la chaleur \u00e0 distance, l\u2019installation de deux machines frigorifiques pour le froid de process, ainsi qu\u2019une pompe \u00e0 chaleur pour l\u2019eau sanitaire, qui intervient dans la production d\u2019eau chaude. Sur l\u2019\u00e9tage socle, la chaleur et le froid sont diffus\u00e9s par des plafonds chauffants et rafra\u00eechissants, tandis que sur les \u00e9tages \u00e0 lits, le chauffage et le refroidissement sont assur\u00e9s par un syst\u00e8me au sol. L\u2019ordre incluait aussi le refroidissement des locaux techniques et des salles IRM (tomographie \u00e0 r\u00e9sonance magn\u00e9tique) ainsi que le raccordement des monoblocs.<\/p>\n<\/div>\n<\/div>\n\n\n\n

La cl\u00e9 du succ\u00e8s: une planification num\u00e9rique et une coordination \u00e9troite<\/h2>\n\n\n\n

Outre la complexit\u00e9 et l\u2019envergure du projet, la collaboration interdisciplinaire entre la planification, l\u2019ex\u00e9cution et l\u2019exploitation de l\u2019h\u00f4pital ont pos\u00e9 des d\u00e9fis particuliers. Tous les travaux se sont appuy\u00e9s sur une planification et une ex\u00e9cution BIM (Building Information Modeling)<\/a> rigoureuses. Le jumeau num\u00e9rique du b\u00e2timent a permis de r\u00e9aliser des tests, des v\u00e9rifications de processus, des corrections pr\u00e9coces et une optimisation de la disposition. Ce projet compte ainsi parmi les premiers grands chantiers en Suisse \u00e0 se baser sur un processus enti\u00e8rement num\u00e9rique.<\/p>\n\n\n\n
