Building installation work

Description

Sund Eigedomsutvikling KF, Sund municipality shall construct sheltered accommodation flats — 20 units over 2 floors. The project shall be constructed together with Sundheimen nursing home on the ground floor. 4 contracts will, thus, be announced for architect and building, constructional engineering and landscape, electro and HVAC and sanitation respectively. According to the original plan, the notice should have already been published, but as the basis had not been completed, it has taken longer. The notice will be published before the general staff holiday, but as it will be published just before the holiday, we are publishing a prior information notice that describes our intentions. According to the plan, the notice will be published in week 27 and the tender deadline will be 24.8.2017. The contracting authority will also hold a site inspection. V01 – Plumbing installations including sanitary, heating, cooling and sprinkler installations for 20 sheltered accommodation flats with the accompanying communal areas. In addition a pipe system shall be delivered for any future removal of radon gas. A rock heat pump plant shall cover the building's basic need, whilst an electrical boiler will cover peak loads. The plumbing contractor will be responsible for the drilling and plumbing work for the energy wells. The heat pump plant shall supply the underfloor heating system that will cover the ground and first floors, ventilation heating and tap water heating. The heat pump system shall be able to prioritise heating tap water, so that the highest possible amount of energy consumption for heating hot water can be obtained from the heat pump. It shall be possible to use free-cooling from the drill holes for ventilation cooling. V02 – Air treatment plant consisting of a balanced ventilation installation for the entire building, as well as some minor extraction systems for kitchen ventilators and the medicine room. One aggregate placed in the technical room in the basement will ventilate the entire building. When the extraction systems are used, supply air from the aggregate is regulated up or extraction down to the zone in question so that the balance is maintained. The air amounts in the communal rooms are controlled by the CO₂/temperature. The “pull-out” system will be used as the fire strategy for the ventilation installations. A bypass shall be assembled passed the aggregate and smoke fan on extraction/rejection. Channels shall not be insulated against fire, as all the channel fees have sprinklers (see the fire concept).
