Abstract (eng): In this Master's Thesis fixed methods that enable renovation with prefabricated elements were formed along with three renovation concepts.
The concepts were a concept for renovating one type of components, renovating an entire building and many of its components and renovating several buildings that form a residential area.
For forming the concepts, two pilot buildings and a pilot residential area that were built during the 1960's and 70's were researched.

In this Master's Thesis different ways to renovate with prefabricated elements, their characteristics and ways to procurement them were researched.
The term concept generation was defined along with product concept generation and service concept generation.
A way to choose a concept was introduced and the prerequisites, threats and possibilities of concept generation were researched.
The pilot buildings and residential area were introduced and selection matrixes were formed for finding the best method of renovation for the customer.
The selection matrix needs to be formed for making the choosing of a renovation method as systematic and objective as possible.

For the procurement of one type of components design build contract of a single building part was chosen, for an entire building's renovation a fixed cost design and build contract was chosen and for renovation of the residential area design and build cooperation contract was chosen.
In all these, the contracts are tendered with preliminary plans so that possible solutions are not delimited too early.

Along with the procurement method and contract form, there are many matters that have impact on the final choice of the renovation method.
Those are the previous experiences of the parties of the contract, their willingness to try new ways to renovate, the expenses of the contract, the time it takes to renovate in situ with different methods, the time the whole contract takes time, the availability of suppliers, insurances and if the building is listed or if other reasons limit the changes in the appearance of the building that renovation with prefabricated modules usually requires.
Abstract (fin): Tämän diplomityön tavoitteena oli muodostaa vakioituja menettelyjä teollisen korjausrakentamisen mahdollistavaa korjausta varten.
Työn yhteydessä luotiin kolme konseptia, jotka käsittivät yhteen rakennusosaan kohdistuvan korjauskonseptin, yhteen rakennukseen kohdistuvan, useita toimenpiteitä sisältävän korjauskonseptin sekä useaan rakennukseen kohdistuvan alueellisen korjauskonseptin.
Konseptien luonnissa hyödynnettiin kolmea koekohdetta, jotka on rakennettu 1960-1970-luvuilla.

Diplomityössä perehdyttiin erilaisiin teollisiin korjausrakentamismenetelmiin, niiden ominaisuuksiin sekä hankintatapaan.
Työssä määriteltiin konseptoinnin käsite yleisesti sekä tuote- ja palvelukonseptit, ja esiteltiin konseptin valinnalle menetelmä, sekä tutkittiin konseptoinnin edellytyksiä, haasteita ja mahdollisuuksia.
Koekohteista esiteltiin perustiedot ja tehtiin valintamatriisit kohteita vastaaville konsepteille, joiden perusteella valittiin tilaajan kannalta paras konsepti.
Valintamatriisi tulee tehdä, jotta korjausrakentamistavan valinnasta tulee systemaattista ja mahdollisimman objektiivista.

Yhden rakennusosan korjaamiseen valittiin hankintatavaksi tuoteosakauppa, yhteen rakennukseen kohdistuvaan, useita toimenpiteitä sisältävään korjaamiseen muunneltu ranskalainen urakka ja useaan rakennukseen kohdistuvaan alueelliseen korjaamiseen yhteistoimintaurakka.
Kaikissa näissä urakat kilpailutetaan toiminnallisilla tavoitteilla, jottei mahdollisia teknisiä ratkaisuja rajata pois liian aikaisin.

Korjausrakentamistavan valintaan vaikuttaa hankintatavan ja urakkamuodon lisäksi rakennusurakan osapuolten aiemmat kokemukset ja erityisosaaminen, heidän halukkuutensa kokeilla uusia korjausratkaisuja, kustannukset, työmaa-aika, hankeaika, toimittajan löytyminen, vakuutukset sekä se, onko rakennus suojeltu tai rajoittavatko muut syyt rakennuksen ulkonäön muutoksia, joita teollinen korjausrakentaminen yleensä edellyttää.
