The premises of Helsinki Vocational College on Prinsessantie street in the Roihuvuori district were modernised in multiple phases. The College remained in operation throughout the modernisation project. Now, approximately 1,000 students in the fields of hospitality, catering, food industry, tourism, nature and the environment are studying in professional-level facilities.<\/p>\n

Helsinki Vocational College is one of the largest vocational schools in Finland.\u00a0<\/span>Helpa, built in 1978, is one of the five campuses of the College.<\/span>\u00a0<\/span>This protected building was designed by the same architects as the Temppeliaukio Church:<\/span>\u00a0Timo and Tuomo Suomalainen.<\/span>\u00a0<\/span><\/p>\n

\u201dHelpa\u00a0was reaching the end of its service life, and the new study programmes also needed new kinds of facilities,\u201d says Project Manager<\/span>\u00a0Jari Rosanti<\/span><\/strong>\u00a0from the Construction Contracting Services of the City of Helsinki, responsible for the construction of infrastructure and public spaces in Helsinki. The most significant changes included the addition of 13 new, modular teaching kitchens and bakeries designed together with the teachers to meet the needs of modern working life.<\/span>\u00a0<\/span><\/p>\n

The school remained in operation thanks to successful phasing<\/h4>\n

One of the most central challenges was the phasing of the project. The 46-million-euro project was implemented in three years, with each phase lasting approximately a year and covering approximately 7,000 square metres. The College stayed in operation throughout the modernisation project.<\/span>\u00a0<\/span><\/p>\n

\u201cThe phasing of the work was a big challenge, and there were a lot of surprises in the demolition phase, in particular,\u201d\u00a0Rosanti says.\u00a0\u201dHowever, Sweco quickly gave us feasible additional plans.\u201d According to Rosanti, smooth co-operation between users, designers, contractors and the client organisation is an absolute requirement for a successful and phased implementation of a project as extensive as this one.<\/span>\u00a0<\/span><\/p>\n

\u201dThe\u00a0project stayed on schedule and within the budget, even if it was hard sometimes,\u201d says\u00a0<\/span>Tommi Mutanen<\/span><\/strong>, Sweco\u2019s Project Manager for the structural design and the person in charge of the worksite.\u00a0\u201dThe\u00a0first phase was the most extensive and difficult one, and we were only a little behind after that. But we managed to pick up the pace in the other phases.\u201d<\/span>\u00a0<\/span><\/p>\n

The old building set the pace for the modernisation. For example, the HVAC routings were embedded in the existing structures, while weather protection required special attention. \u201cWe couldn\u2019t let the structures get wet at any point,\u201d Mutanen states.<\/span>\u00a0<\/span><\/p>\n

The project team also performed air leakage tests and prepared the necessary moisture control documents in connection with the waterproofing renovations. The structures were dismantled down to the load-bearing frame,\u00a0<\/span>and the College got a new facade and roof. \u201c<\/span>In addition to this, half of the 700 windows were\u00a0renovated\u00a0and half were replaced.\u00a0<\/span>All\u00a0<\/span>thermal insulations were also renovated to meet today\u2019s standards,\u201d Mutanen says.<\/span>\u00a0<\/span><\/p>\n

Building services equipment on the roof and in the basement<\/h4>\n

There was no room for modern technology in the building due to the low ceilings and long distances between pillars. The solution was building new HVAC machine rooms on the roof.\u00a0<\/span>During the design process, the size of the machine rooms increased: As a result, there are more than 1,000 square metres of HVAC equipment on the roof.<\/span>\u00a0<\/span><\/p>\n

\u201cThe load-bearing structures also needed to be strengthened since, on a flat roof, the edges of the machine rooms may have piles of snow on them,\u201d Mutanen says. The roof\u2019s prestressed double-T slabs made of reinforced concrete were strengthened with adhesive steel plates. \u201cAdhesive reinforcing of double-T slabs means reinforcing a structure in class 1, which is considered an exceptionally demanding design project.\u201d<\/span>\u00a0<\/span><\/p>\n

The electrotechnology control centre was placed in the basement, which was an efficient way of using the indoor spaces. \u201cWe designed a technical channel under the base floor, which is partly ventilated and partly on the ground,\u201d Mutanen says. \u201cThe solution is cost-efficient since we in any case needed to remove the floors to be able to install sewer lines, drains, radon piping and thermal insulation.\u201d<\/span>\u00a0<\/span><\/p>\n

Better indoor conditions with less energy consumption<\/h4>\n

Since the College was in operation throughout the project, the teaching facilities and temporary facilities had to be carefully protected. \u201cIn addition to weatherproofing, the construction site was isolated so that the impurities wouldn\u2019t enter the teaching rooms,\u201d Mutanen says. The planning also aimed to reduce the disturbances caused by the worksite. \u201cThere\u2019s always noise, but we managed to reduce the levels with airproof noise walls.\u201d<\/span>\u00a0<\/span><\/p>\n

The renovation project improved the indoor conditions and the functionality of the facilities significantly. \u201cThe users are happy with the modern facilities, and we have received particularly positive feedback for the teaching kitchens with the new appliances,\u201d Rosanti says. \u201cThe indoor air conditions of the College are now at a new and better level. It is also consuming substantially less energy.\u201d<\/span>\u00a0<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n
