Eleni Antoniades Snell ViceChair of the Institution of Environmental Sciences Trustee and Board Member of the IES Project Environmental Lead- Aviation and Infrastructure Construction Environmental Management and Assessment Started career coordinating transport related EIAs in 2002 (highways, roads, bridges, airports, railways) then went on to being EIA project manager and reviewer Started carrying out construction monitoring in early career and went on to be construction environmental lead on site Now- work mostly on Antarctic EIAs and environmental lead for aviation and infrastructure- mostly in defence email: e.antoniades@eaenvironmental.com linkedin.com/in/eleniantoniadesenvironmental
- 3. Launched officially inJune 2020 Fourth community debate: 1) Competency in EIA, June 2020 2) Net Zero by 2050 and EIA ,October 2020 3) EIA for Better Design, March 2021 EIA Working group established October 2021 Preparing paper Workshop Nicola Parker- IES Trustee and Board Member, DIO Senior Environmental Planner Tim Snell – Infrastructure Planning Lead IES EIA Community Group
- 4. From concept toconcrete: Bridging the gap between EIAs and construction Why is there a gap?
- 5. A) TIME Typical timelineof infrastructure and development project… varies hugely but can take a minimum of 12 months for a small development project with planning permission EIA Stage and Planning Process Planning Permission Tender Stage Construction Stage
- 6. EIA Stage andPlanning Process Maximum periods required by regulations for the planning process 21- 24 weeks= 6 months •EIA Screening Opinion Request to Local Planning Authority (LPA) •EIA Screening Opinion from LPA •3 week Period to provide Screening Opinion •If Developer Disagrees with Screening Opinion Can Request Opinion From Secretary of State (3 Week Period) Screening Opinion 3- 6 weeks •Baseline Data Gathering, Initial Surveys and Identification of Key Constraints (Public Consultation Optional) •Preparation of Scoping Report by Developer •Request of Scoping Opinion from LPA •Request Additional Information/Opinion from Statutory Consultees •5 Week Period for LPA to Provide Scoping Opinion Scoping Opinion 5 weeks •Additional Data Gathering, Detailed Surveys, Assessment of Environmental Impacts •Preparation of EIA Report by Developer •Submission of EIA Report and Planning Application •EIA Report Published and Distributed to Stat. Consultees •16 Week Period for LPA to provide Determination EIA Report 16 weeks
- 7. B) DIFFERENT REGULATORYFRAMEWORKS The regulatory framework and guidance related to environment and sustainability governing each stage is differs EIA Stage •Town and Country Planning Regulations (EIA Regulations) •EIA Directive •Other environmental regulations such as Net Zero, Biodiversity Net Gain, Water Framework Directive •EIA Screening •EIA Scoping •Environmental Surveys and Assessments •EIA / Environmental Statement Preparation •Outline CEMP Planning Stage •Permitted Development Rights •EIA Screening Opinion from Local Planning Authority with environmental requirements •Planning permission with conditions •Development Consent Order (DCO) with requirements •Hybrid Bill/ Act with planning permission and series of conditions Tender Stage •Developer’s own sustainability and environmental policies •UK Government procurement requirements •National Net Zero requirements Construction •Contractor’s own Environmental Management System •e.g. ISO 14001:2015 •Contractors Energy Management System •e.g. ISO 5001 •Contractor’s own sustainable procurement policy •Voluntary assessments e.g. BREEAM, CEEQUAL •Additional environmental regulations for construction e.g. related to emissions, PPC, environmental permits, waste permits, consents
- 8. C) Different professionalsat each stage Even though Developer will be the same through out process, the organisations involved at the EIA and the Construction stages will differ Most professionals work either in EIA or Construction EIA Stage • EIA Reviewer/Project Lead • EIA Co-Ordinator • Topic Specialists/Chapter Lead • May or may not include early contractor involvement Construction stage • Environmental managers of contractor or HSE managers • Environmental monitoring and survey specialists e.g. contaminated land specialists, air quality monitoring, ecology team, noise and vibration specialist
- 9. Participant survey, allanonymous • Do you work in EIA and/ or construction? • a) I work only in EIAs and not construction • b) I work only in the construction phase • c) I work in both EIA and construction phase • 2) If you work in EIA, which of the following is true: • a) I don’t generally visit or work on construction sites, mostly office based • b) I may have meetings but stay in the compound/office • c) I do have a hands on role during construction • 3) If you work mainly in construction, which of the following is true: • a) I have been involved with EIA and/or the planning process • b) No/ limited experience in EIA, focus on construction C) Different professionals at each stage
- 10. We will breakout into three groups with two themes: EIA or Construction… pick a side • We will break out into three groups • Group (1) and (2) mainly EIA and Planning Stage- Nicola and Tim • Group (3) mainly construction phase -Eleni • In groups, the task is to work out the environmental budget for the construction stage Construction team: Aim to win the tender • EIA team: Aim is to minimise potential impacts and get project through planning Results and Workshop
- 11. Workshop: the hypotheticalproject…development of an existing military runway The hypothetical project is an existing airfield with a single runway with a length of 2,800 meters : It has been used as a military runway since the 1940s Trees and vegetation will need to be cleared prior to construction The project will include demolition of existing runway, taxiways and apron The existing airfield operating surfaces (i.e. runway, taxiways, apron) will be completely broken out, crushed, processed and recycled on site The project will involve excavation below ground for new drainage
- 13. Potential adverse environmentalimpacts from construction which were identified during EIA 1. Ecology: There are potentially nesting birds present in the trees
- 14. Potential adverse environmentalimpacts from construction which were identified during EIA 2.Contamination: There is potential for contamination from hydrocarbons and PFAS on site due to previous use of the runway. There is no ground investigation or desk study available
- 15. Potential adverse environmentalimpacts from construction which were identified during EIA 3. Air quality and dust: There will be dust arising due to demolition and crushing of concrete on site
- 16. Potential adverse environmentalimpacts from construction which were identified during EIA 4. Environmental management: The project will require a Construction Environmental Management Plan (CEMP), Site Waste Management Plan (SWMP), Materials Management Plan (MMP)

- 19. Construction environmental impactswhich arose during construction but were not identified in EIA Screening Report • EIAs are focussed on the site based impacts of construction and less focussed on the “transboundary impacts” of materials and energy • Where are the materials and fuels coming from? • Fuel use -of asphalt plant and concrete batching plant. EIAs do not include this level of detail or focus on White Diesel 0.00 20,000.00 40,000.00 60,000.00 80,000.00 100,000.00 120,000.00 140,000.00 160,000.00 180,000.00 Gas Oil/Red Diesel (ltr) Site Plant/ Equipment Heating oil (ltr) Asphalt Plant White Diesel (ltr) Site Vehicles
- 20. Construction environmental impactswhich arose during construction but were not identified in EIA Screening Report • Water use in concrete batching plant. For concrete production during a runway refurbishment project, the concrete batching plant used 9,182,000 litres over a one year period whilst site compound used 213,000 litres over the same period • Underestimate of energy requirements of construction with focus on the site compound office rather than heavy plant and machinery, often require generator use • No assessment of lighting requirements during construction • No previous ground investigation for contamination. Elevated levels of contaminants in groundwater and groundwater required remediation on site, as well as discharge consent • Dewatering strategy- groundwater information was not obtained and there was no identification of the dewatering strategy. Programme allowance for discharge consent applications or at least potential options should be identified
- 21. Construction environmental impactswhich arose during construction but were not identified in EIA Screening Report • Materials Arising – quantity of excavated materials arising on site was not assessed. Some time is required for either a waste permit or for the preparation of a Materials Management Plan under the Construction Code of Practice. • For example, RAF Marham runway refurbishment re-used 320,000 tonnes of arising on site • Environmental impact of importing materials- quantities of concrete materials such as limestone may be imported from far. At EIA stage rarely possible to know where materials will come from and volume estimates are approximate. • For example, for RAF Marham runway refurbishment used 241,147 tonnes of aggregates to the site for the on-site production of concrete and asphalt.
- 22. Conclusion • Early contractorinvolvement during EIA Stage • Contractors could identify how practical the environmental mitigation measures proposed are to implement • Cost estimate of environmental mitigations should be included • Tenders should explicitly list the environmental mitigation measures to be priced, as well as permits • Clients/ Developers would save costs if contamination investigations are carried out as early on as possible in a project • Develop any remediation strategies in advance • Environmental professionals working in construction phase should have a beginners course in EIA to understand regulatory framework • EIA professionals should have experience in the construction phase and understand the construction process • Work placement or work exchange between office and site based work
