Denmark – Works for complete or part construction and civil engineering work – Rammeaftale om renovering af fire (4) højhuse i Brøndby Strand Parkerne

With this tender notice, the contracting authority is awarding a framework agreement for the renovation of four (4) high-rise buildings in Brøndby Strand Parkerne. The procurement is conducted as a competitive dialogue in accordance with §§ 67-72 of Act No. 1564 of 15 December 2015, as amended ("the Public Procurement Act"). The framework agreement covers the complete renovation of four high-rise buildings, including facade renovation with renovation of the high-rise buildings' facade system consisting of a climate screen with facade panels, window elements, and additional insulation, as well as a steel structure to support the climate screen, internal renovation, and energy optimization, etc., carried out by a main contractor. The high-rise buildings are located at Ulsøparken 1 (UL1), Hallingparken 1 (HP1), Hallingparken 2 (HP2), and Hallingparken 7 (HP7), 2660 Brøndby Strand, and are essentially identical in terms of appearance, construction, and number of dwellings. A picture of one of the high-rise buildings is inserted in section 1.1 of the Descriptive Document. The complete renovation is carried out as part of the overall plan HP4. The framework agreement is awarded and entered into with one tenderer, cf. section 8.7 on tender evaluation in the Descriptive Document. The contracting authority places orders and enters into contracts under the framework agreement by direct award. The framework agreement and the individual contracts are based on AB 18 with the specifications that appear from the framework agreement, cf. section 3.1 in the draft framework agreement. The contracting authority intends to use the framework agreement to carry out the complete renovation of all four high-rise buildings. The contracting authority intends to place orders under the framework agreement so that the renovation of all four high-rise buildings can be carried out in accordance with the contracting authority's overall renovation schedule for the high-rise buildings (Overall Schedule, cf. document and drawing list, cf. item 3.1 litra f) in the draft framework agreement), and as four (4) successive orders – Draw 1-4 – covering one high-rise building at a time. It is intended that Draw 1 covers HP7, Draw 2 covers HP1, Draw 3 covers HP2, and Draw 4 covers UL1. The Overall Schedule is indicative and not binding for the contracting authority as stated in section 1.1 of the Descriptive Document. The contracting authority has chosen to structure the procurement of the overall renovation task for the four high-rise buildings as a framework agreement, as this – if the cooperation with the winning tenderer (the contractor) proceeds satisfactorily – provides the opportunity to optimize the renovation process from high-rise building to high-rise building by utilizing the experiences that the contractor builds up under the previous draws on the framework agreement. It is also crucial for the contracting authority that the renovation of the four high-rise buildings is carried out in a satisfactory manner in terms of quality and time and in accordance with the framework agreement and the individual contracts. This is particularly important as the contracting authority, as a general housing organization, has limited ability to handle cost increases without consequences for the rent level. By structuring the procurement of the overall renovation task for the four high-rise buildings as a framework agreement, the contracting authority gains the opportunity to avoid further orders if the cooperation with the winning tenderer (the contractor) does not proceed satisfactorily, cf. sections 6-8 and section 27 in the draft framework agreement. The framework agreement has a duration of four years, cf. section 4 in the draft framework agreement. The scope and content of the framework agreement are described in the draft framework agreement with attachments. The contracting authority has, in accordance with the Public Procurement Act's § 49, paragraph 2, considered dividing the renovation task for the four high-rise buildings into separate contracts. Due to the nature and complexity of the renovation project, including the significant need for coordination of interfaces between trades, the contracting authority has assessed that a main contract is most appropriate. A division into trade contracts and separate framework agreements would result in a significant risk of coordination challenges, delays, and unclear allocation of responsibility. The renovation project is therefore carried out as a main contract based on a single overall framework agreement. The framework agreement is tendered with a system supply, which includes the high-rise buildings' facades. The system supply includes (1) the high-rise buildings' facade system consisting of a new complete climate screen with facade panels, window elements, and applied additional insulation of the underlying facade, and (2) the high-rise buildings' steel structure, which constitutes a new supporting steel system for supporting the entire climate screen. Reference is made to the Job Description for the System Supply for the high-rise buildings' facades, cf. document and drawing list, cf. item 3.1 litra f) in the draft framework agreement, for a more detailed description of the system supply. The facade works constitute a central and technically complex part of the overall works, as it concerns the renovation of high-rise buildings in 16 storeys with an existing construction, which the new facade system must be integrated into and built together with. The tenderers' choice of technical and construction-related solutions within the areas that are tendered as a system supply has a direct influence on the execution process, execution rate, and coordination. These circumstances can therefore not be determined precisely enough in advance for the tender to be carried out as an open or restricted tender without dialogue with the tenderers. The tenderers, with their market knowledge and technical expertise, have a significantly better basis than the contracting authority for identifying and projecting suitable solutions. Competitive dialogue is therefore necessary to determine and optimize the conditions regarding execution process, execution rate, and coordination, which depend on the tenderers' system choice. The tender is therefore carried out as a competitive dialogue in accordance with the Public Procurement Act's § 67, paragraph 1, litra a and b. The dialogue is carried out to clarify and specify conditions regarding execution process, execution rate, and assembly technique, which follow from the tenderers' system choice within the framework of the specified functional requirements.
