Water Supply Improvement on Ciaurriz Street, Mairena del Aljarafe

This Spanish public works tender concerns upgrading the water supply infrastructure on a specific section of Ciaurriz Street in Mairena del Aljarafe (near Tomares), Andalusia. The project focuses on the segment between Herradura and Muérdago streets. Given the 'plumbing' trade classification and the project description, the work likely involves excavation, pipe laying (new or replacement), connection to existing mains, backfilling, and reinstatement of the road surface. It probably includes all necessary fittings, valves, and testing to ensure a functional and compliant water supply system.

The estimated contract value is €87,725.14, which suggests a relatively small-scale project, likely involving a localized section of pipework rather than a large network upgrade. The absence of detailed CPV codes makes a precise assessment of complexity difficult. Contractors should investigate factors such as the pipe diameter, material specifications, traffic management requirements, potential for unforeseen ground conditions, and interface with existing utilities to properly gauge the project's demands. The deadline for submission is April 13, 2026, providing approximately one month for tender preparation.

Before bidding, prospective contractors should seek clarification on the design specifications, including pipe material, diameter, pressure requirements, and testing protocols. Clarification on any existing underground utilities that may affect the excavation and construction work is critical. Understand the contract terms related to payment milestones and potential penalties for delays to assess any risk. Any specific environmental or permitting conditions applicable to the area needs understanding as well.
