Expired Tender for Road Paving Works by the Local Government Committee of Ames City Council, Spain

Tender Title: Road Paving Works in Coira

Type of Procurement Procedure: Simplified Open Tender

Nature of Contract: Works Contract (Construction)

Main Classification (CPV): 45233251 - Road resurfacing works

Project Location: Ames, Province of A Coruña, Autonomous Community of Galicia, Spain

Project Overview: Paving works on roads in designated areas, part of municipal infrastructure maintenance and upgrading projects.

Scope of Works and Main Content

Pavement Demolition and Clearance: Removal of existing damaged or aged pavement layers (may include asphalt concrete or cement concrete pavement), and transportation of waste to designated disposal sites.

Subgrade and Base Course Treatment: Inspection of the exposed subgrade, with compaction, leveling, or partial replacement as necessary to ensure bearing capacity meets design requirements.

New Pavement Layer Installation:

Materials: Specific technical requirements such as asphalt grade, aggregate gradation, thickness (e.g., total thickness may be between 5-20 cm, divided into base course, binder course, and wearing course) must be clarified.

Construction Process: A series of standardized operations including mix production, transportation, paving (using a paver), compaction (using steel-wheeled and rubber-tired rollers). Compaction degree, smoothness, and thickness are core quality control indicators.

Ancillary Works: May include adjustment or repair of curbs and edge stones; cleaning and repair of gutters and catch basins; re-marking of road lines; and smooth connection treatment with existing pavements, manhole covers, and entrances/exits.

Preliminary Preparation and Demolition Phase:

Precise Survey and Marking: Use of equipment such as ground-penetrating radar to confirm the location of underground utilities (water supply, drainage, electricity, telecommunications) and coordination with relevant municipal departments for protection or relocation plans.

Selective Demolition: Possible use of cold milling machines for precise thickness removal of the original asphalt surface layer. Milled material requires on-site screening and testing, with planned recycling rate (Spain typically requires ≥70% for base courses or temporary roads).

Subgrade Defect Treatment: Excavation of areas with subgrade defects such as pumping or settlement, potentially using lime/cement in-situ stabilization, graded crushed stone replacement, or geogrid reinforcement.

Base Course and Structural Layer Construction Phase:

Base Course Materials and Process: May require the use of cement-stabilized aggregate or asphalt-stabilized base courses, with clear standards for 7-day unconfined compressive strength (e.g., ≥3 MPa) and compaction degree (≥95% of standard Proctor density).

Drainage System Integration: Repair or construction of shoulder ditches and permeable base course drains to ensure proper drainage within the structural layers and prevent water damage.

Surface Course Paving and Finishing Phase:

Asphalt Mixture Performance: May specify SBS-modified asphalt to improve rutting and cracking resistance, especially at intersections and bus stops. Mix design must comply with Spanish standard gradation requirements such as F-20 or F-12.

Paving and Compaction Process: Requires the use of pavers with ultrasonic sensors to ensure smoothness (gap ≤3mm when checked with a 3-meter straightedge), and specific temperature ranges and pass counts for initial, intermediate, and final compaction.

Joint Treatment: Hot joints or specialized sealants must be used for joints between new and old pavements and daily construction joints to ensure smoothness and waterproofing.

Application of Smart and Quality Control Technologies

Digital Construction Monitoring: Use of intelligent compaction systems to monitor roller passes, temperature, and compaction degree in real-time, with data uploaded directly for supervisory review.

Material Traceability: Asphalt mixing plants must provide electronic delivery notes for each batch of mixture, enabling full-chain traceability from production to paving.

Comprehensive Traffic and Logistics Management Plan

Time-Phased and Segmented Dynamic Planning: Requires a plan for switching construction segments adjusted hourly or daily, with real-time coordination with municipal traffic management for signal timing. Night work (22:00-06:00) may be required to maximize efficiency, but must comply with noise limits (e.g., ≤45 dB at night).

Emergency Access Guarantee: Clear designation of 24-hour access routes and contact information for emergency vehicles such as fire trucks and ambulances.

Environmental Compliance and Sustainability Implementation

Carbon Emission Calculation and Reporting: May require calculation and reporting of the project's embodied and operational carbon emissions per Spanish Royal Decree 105/2023, and the use of low-carbon materials (e.g., asphalt with high RAP content).

Real-time Noise and Dust Monitoring: Installation of networked environmental monitoring equipment at the site boundary, with publicly accessible data.

Water Resource Management: Establishment of rainwater sedimentation ponds, with required standards for construction water recycling rate.

Duration and Schedule Management

6-Month Duration: The contractor must develop a detailed construction schedule, considering influencing factors such as weather (e.g., rainy season), material supply, and holidays, to ensure completion within the contractually stipulated 6 months.

Phased Delivery: Construction may need to be carried out in sections to restore traffic in some areas as soon as possible, which must be clearly defined in the plan.

Commissioning, Acceptance, and Warranty

Preliminary Acceptance: After project completion, a preliminary inspection by the technical department of the City Council to verify compliance with technical specifications.

Final Acceptance: Conducted after the specified defects liability period (typically 12 months, subject to contract) ends.

Warranty Period: The contractor is typically required to provide a warranty of at least 12 months for the works, responsible for repairing issues arising during this period due to material or workmanship defects.

Community Relations and Public Service Commitment

Structured Communication Mechanism: Establishment of a project-specific hotline and weekly community briefings, providing affected residents with 48-hour advance notice of construction activities, temporary water/power outages.

Accessibility Guarantee: Continuous and safe passage for pedestrians, tactile paving, and ramps must be maintained during construction, with compliant temporary accessible facilities.

Full Lifecycle Operational Data Delivery

Digital As-Built Documentation: Delivery of an L3 precision model compliant with Spanish UNE-EN ISO 19650 standards, containing material properties, thickness, test data for each pavement layer, and precise locations of underground utilities.

Preventive Maintenance Recommendation Report: Based on pavement condition index surveys, provide a 5-year forecast for maintenance cycles and costs.
