Hot water is prepared for the ground floor using the existing hot water preparation centrally in the boiler room. On the first floor, hot water is prepared using instantaneous water heaters. Sanitary installation: Waste water pipes will be re-laid and connected to the new toilets and washbasins. Hot water is prepared decentrally using instantaneous water heaters. Cold and hot water is supplied to the individual taps using copper pipes and metal composite pipes. Prefabricated wall installations will be installed in the washrooms. The prefabricated wall installations must be integrated using drywall.

Measures before work begins: Before scaffolding work begins, the contractor must determine whether there are any systems in the planned work area that could endanger insured persons. If the contractor accepts orders that are to be carried out at the same time and place as orders from other contractors, he is obliged to coordinate with the other contractors to the extent that this is necessary to avoid mutual danger. Electrical systems and equipment: If electrical equipment with a mains connection is used for scaffolding work, it must be operated via a special feed point in accordance with DIN VDE 0100-704. Electrical equipment includes, for example, electrically operated construction hoists and drilling machines.

Restricted invitation to tender with public participation competition Vob/a demolition and dismantling work 1. The construction project involves the new extension of the fire station with 4 vehicle parking spaces and the necessary social rooms. The existing building will be partially demolished and rebuilt. The additional base for the vehicle hall, including the foundation and upstands, will be built using solid construction. The social wing on the ground floor and the building dividing wall to the hall will be rebuilt using solid construction. The upper floor of the social wing and the roof and walls of the vehicle hall will be made of wood. The "sports center" part of the existing building will be retained and in use during the construction period. Fire service access roads, the access to the construction yard (fire service location during construction) and escape and rescue routes must be kept clear throughout the entire construction phase, see appendix. Everything else must be agreed upon with the construction management, particularly exceptions. 2. During the project, some work may be carried out by construction yard employees and fire service members on their own. This may result in various items being omitted altogether or quantities in certain areas of various items being reduced. The omission or reduction in quantities of these items does not entitle the contractor to make claims for lost profits or claims for an increase in unit prices. The price inquiry or requirement items must be filled out without fail, as it is possible that these items will also be implemented. The bidder acknowledges these preliminary remarks by signing the list of services. 3. The construction site toilet and break rooms must be provided by each contractor themselves. Energy, water and electricity are provided free of charge. 4. Upon acceptance of the order, the contractor acknowledges the dates stated in the preliminary remarks and the construction schedule as binding and will, if necessary, carry out the necessary work outside of working hours at no extra cost so as not to jeopardise the deadlines for subsequent work. The contractor undertakes to ensure that the number of workers is adequately available based on the amount of work and the number of working days. 5. The contractually binding partial deadlines are set out in the attached construction schedule. 6. The work advertised must be carried out in installments as construction progresses. This does not entitle the contractor to make additional demands. 7. Services that exceed the order amount require prior written approval; otherwise no payment will be made! Accordingly, supplementary offers must be approved in good time (at least 3 weeks) before execution. 8. Depending on the trade, the following documents must be enclosed with the final invoice in paper form and digitally (copied onto a CD or data carrier).

Flexible action with fast reaction times and short arrival and departure times is essential for this construction project. In view of the short execution time, this also applies to instructions from the construction management to carry out work at short notice in order not to hinder or delay subsequent trades and the overall construction process. Any additional work resulting from this must be included in the unit prices. D. General information on the service description Each item shown is to be understood as a finished job and as a service that complies with the regulations, is properly crafted and is ready for use and operation, including all ancillary services. - Additional technical contract conditions - Electrical installation DIN 18 382 The general technical regulations (ATV) for construction work of the Vob, Part C, become part of the contract. Measurements and quantity compilations as the basis for calculation are only to be prepared on forms from the engineering office. The forms are provided free of charge and must be requested in good time. The presence of a contractor employee with technical and local knowledge during the acceptance of the high and low current technical systems, in accordance with the construction certificate and the applicable building inspection regulations, by a building inspector-approved expert, is covered by the unit prices. The contractor must coordinate the provision of his services with - previous and subsequent - trades that technically affect his own services, so that his own services and his own execution dates are carried out correctly in terms of the detailed execution steps and functional accuracy.

Everything else, especially exceptions, must be agreed with the construction management. 2. During the project, some work may be carried out by municipal yard employees and firefighters themselves. This may result in various items being omitted altogether or quantities in parts of various items being reduced. The omission or reduction in quantities of these items does not entitle the contractor to make claims for lost profits or claims for an increase in unit prices. The price inquiry or requirement items must be filled in without fail, as it is possible that these items will also be carried out. The bidder acknowledges these preliminary remarks by signing the list of services. 3. The material costs and wage cost components requested in the individual items must be filled in without fail.
