The chambers are often located under sidewalks, green areas or near subscriber substations and can be identified by their characteristic cast-iron or concrete covers. 1. Dimensions and construction The dimensions vary significantly depending on the number of pipes passing through and their diameter: • Typical dimensions: They are usually rectangular or square. Small chambers start at 2.0 х[IM5.1] 2.0 metres, while large distribution nodes can reach 5.0 х 8.0 metres or more. • Depth: They are usually buried at a depth of 2 to 4 metres to ensure minimum cover over the pipes and space for servicing beneath them. • Material: They are constructed of reinforced concrete (cast-in-place or prefabricated) with waterproofing. 2. Other technical characteristics • Equipment: Inside are steel gate valves, drainage systems, air vents, and U-shaped or lyre-shaped expansion joints to absorb thermal expansion. • Access: Access is provided through standard manholes. Entering them without authorization and protective equipment is extremely dangerous due to the risk of high temperatures (up to 150°C in the event of accidents) and the presence of gases. The time limit for performance of the subject of the procurement is 48 (forty-eight) months or until the stated estimated value is reached, whichever event occurs first. Procedure: open. Estimated value: 1,100,000 EUR. Review the original TED notice for the complete requirement, lots, amendments and attachments.
