GPP Training toolkit 7.7. Road D esign, Construction and Maintenance

This toolkit module provides an overview of the environmental impacts of road design, construction, and maintenance. It covers topics such as material choice, resource efficiency, water and habitat conservation, noise reduction, and procurement models. The module also includes information on EU GPP criteria, procurement stages, and verification methods.

  1. GPP Training toolkit7.7. Road Design, Construction and Maintenance

  2. GPP Training Toolkit Module 2: Strategic Aspects of GPP Module 4: Needs Assessment Module 1: Introduction Module 7: Operational (Roads) Module 5: Circular Procurement Module 6: Market Engagement Module 3: Legal Aspects of GPP Module 7.7 – Road Design, Construction and Maintenance

  3. Environmental impacts Key choices about road design with environmental impacts Construction: • Material choice • Materials production • Materials transportation • Earthworks and groundworks Use: • Rolling resistance • Congestion • Drainage • Noise Module 7.7 – Road Design, Construction and Maintenance

  4. Scope What is included in the EU GPP Criteria • Road construction: the preparation and building of roads • Road maintenance: all actions undertaken to maintain and restore the serviceability and level of service of roads • Road reconstruction: work performed to upgrade the network or replace the entire road section Module 7.7 – Road Design, Construction and Maintenance

  5. Scope What is included in the EU GPP Criteria (cont.) Criteria related to: • Ability of the tenderer • Pavement-vehicle interaction • Resource efficient construction • Water and habitat conservation • Noise • Congestion • Maintenance and rehabilitation strategies Module 7.7 – Road Design, Construction and Maintenance

  6. Procurement Models Procurement model and contract types Road contract types Procurement Models: • Separation of design and build • Combination of design and build (DB) • Design, build and operate (DBO) or design, build, finance, operate (DBFO) • Delivery consortia • Development/ delivery partners • Alliancing • Framework agreements • PPP/PFI • Early contractor involvement More information in: • Procurement Practice Guidance Document for Roads Module 7.7 – Road Design, Construction and Maintenance

  7. Procurement stages Points where environmental criteria can be added • Preliminary scoping and feasibility • Detailed design and performance requirements • Construction and major extensions • Use of the road • Maintenance and operation • End-of-life i.e. road decommissioning More information in: • Procurement Practice Guidance Document for Roads Module 7.7 – Road Design, Construction and Maintenance

  8. Overview EU GPP road design, construction & maintenance approach Material use • Design, specification and site management to maximise the on-site re-use of excavated materials and soils, and use of construction materials with a high recycled or re-used content • Design and construction to achieve low rolling resistance and associated fuel consumption (plus monitoring during the use phase) • Design and specification to reduce embodied impacts and resource use associated with construction materials. • Increasing material durability and reducing maintenance needs Module 7.7 – Road Design, Construction and Maintenance

  9. Overview EU GPP road design, construction & maintenance approach Management • Maintenance and rehabilitation strategies including a monitoring plan and a maintenance plan • A Traffic Congestion Mitigation Plan evaluated by LCC. • Introducing water pollution control components and storm water retention capacity in the drainage system • Specification of approaches to lower noise emissions during construction, use and maintenance phases Module 7.7 – Road Design, Construction and Maintenance

  10. EU GPP Criteria Road design, construction and maintenance (2016) Examples: • Selection criteria (SC) – main contractor shall have relevant competencies and experience • Technical specifications (TS) – maximum temperature for laying bituminous mixtures shall not exceed 140 degrees Celsius • Award criteria (AC) – points awarded in proportion to the reduction of CO2 emissions per tonne of aggregates • Contract performance clauses(CPC) – contractor will implement a system to monitor and report on actions involving excavated materials and soil during work on-site. For full criteria see: • EU GPP Criteria for Road design, construction and maintenance Module 7.7 – Road Design, Construction and Maintenance

  11. Verification What to ask for? When? Compliance with GPP criteria needs to assessed both at the time of selection of best offer and during the contract execution phase. Checking compliance with GPP criteria for roads • Third party auditing • LCA/ LCC analysis • Monitoring data • Management plan • Design plan • Modelling and test data • Technical reports For full verification instructions see: • EU GPP Criteria for Road Design, Construction and Maintenance Module 7.7 – Road Design, Construction and Maintenance

  12. Verification Examples from the criteria C3: Incorporation of recycled content When materials are delivered to the work site, recycled content claims with clear traceability shall be verified for each batch of product Verification: The main construction contractor or the DB contractor or the DBO contractor shall verify claims by providing: • An independent third party certification of the traceability and mass balance for the product and/or recyclate • Or equivalent documentation provided by producer(s) Module 7.7 – Road Design, Construction and Maintenance

  13. Verification Examples from the criteria C4: Monitoring of the low temperature asphalt The laying temperature of the low temp. asphalt shall be verified for each batch of product at the worksite. Verification: The main construction contractor or the DB contractor or the DBO contractor shall verify claims by providing: • An independent laboratory certification of the maximum laying temperature of the asphalt • Or equivalent documentation provided by asphalt producer(s) Module 7.7 – Road Design, Construction and Maintenance
