Denmark – Construction work – AAAB afd. 18 - Hørgården

Tender for a total enterprise concerning AAAB Department 18 demolition and reconstruction of existing low-rise residential buildings constructed in the Danalea module system. The demolition of dwellings, laundry and heating plant functions also includes related light structures, including sheds, garages and canopies. The project is carried out with support from Landsbyggefonden. The department comprises a total of 149 residential units equivalent to 12,211 m², plus laundry (96 m²) and heating plant function (93 m²), totaling 12,400 m². The buildings comprise 4 types of dwellings. Additionally, 309 m² of garages have been established, which must be demolished and re-established to the same extent. The buildings were constructed in 4 phases in 1979 (Phase 1 – Hørgård 217-327), 1980 (Phase 2 Hørgård 133-215), 1981 (Phase 3 – Hørgård 89-131) and 1982 (Phase 4 – Hørgård 27-87). The buildings comprise 3 types of dwellings + laundry and heating plant function:

• 2-room apartments - 69 units totaling 4,818 m²

• 3-room apartments - 54 units totaling 4,585 m²

• 4-room apartments (2-storey apartments) - 26 units totaling 2,808 m²

• Laundry (96 m²) and heating plant function (93 m²)

It is a prerequisite for the realization of the project that the existing bored foundations must constitute an integrated and essential part of the primary load-bearing foundation system of the building – this does not apply to the laundry and heating plant function, which are constructed as new buildings within the existing geometry and without a requirement to reuse foundations. Therefore, a project is desired that combines a purposeful and production-rational execution method with well-functioning residential functions and satisfactory building technical quality. The project is, in addition to the legislative framework, including the planning framework, subject to the following governing requirements:

• The total area of the dwellings (excl. sheds) must be exactly 12,211 m² gross floor area.

• The project must contain 149 dwellings of the same size as the existing dwellings + laundry (96 m²) heating plant function (93 m²)

• All dwellings must have heavy concrete ground cover, and a minimum overhang of 350 mm in accordance with Landsbyggefondens standard.

• The distribution of dwelling sizes and types must be in accordance with the existing types of dwellings. Reference is made to the Project Documents in the tender material for the complete content of the task. The total enterprise includes the design of layout proposals/project proposals, authority project and execution project. The total contractor is responsible for authority applications, project management, site management, specialist inspection, follow-up, IT management and work environment coordination (P+B), environmental and resource coordinator (MRK) etc. It has been decided to tender the project as a whole in a total enterprise. The reason for this is that it has been assessed to be the most optimal for the project both to avoid the coordination risks and reduce the lines of responsibility in the project, but also to achieve the best solution for the project by allowing the total contractor to propose optimizations during the tender period. It is assessed that the tendering form tender with negotiation can be used in accordance with the rules hereof, since it is a question of a total enterprise, where adjustments can be made in connection with the tender, for which there may be a need for prior negotiations.
