Tenders Are Invited For Soil-Decontamination Work – Execution Of Works - Contaminated Site Remediation For T ... in Romania

Work Detail

Soil-Decontamination Work – Execution Of Works - Contaminated Site Remediation For The Project Establishment And Development Of The Urban Garden Corvinia Hunedoara. According To The Technical Project Developed By Total Business Land S.R.L., The Intervention Plan Combines Two Minimally Invasive Complementary Technologies, Distributed Over Two Clearly Delimited Contamination Areas: • Area A (North): Area Of ​​22,187 Sqm (Perimeter 654 M) Treated By On-Site Washing Of The Granular Material. • Zone B (South): Area Of ​​11,816 Sq M (Perimeter 593 M) Treated By Isolation And Geotechnical Encapsulation. Description Of The Works 1. Preparatory Works And Site Organization Before Starting The Actual Remediation Phases, Landscaping Works Will Be Carried Out To Ensure Waste Traceability And Control Dust Emissions: • Deforestation And Chopping: Cutting And Chopping All The Abundant Spontaneous Vegetation On The Site, Followed By Transporting The Material For Recovery Or Composting. • Technical Platform: Setting Up A Platform For The Organization Of Containerized Offices And The Location Of The Treatment Facility. • Tire Control: Installation Of A Wheel Wash Ramp To Prevent The Dispersion Of Pollutants Outside The Construction Site. • Perimeter Security: Fencing The Work Areas On The South And Southeast Side For Physical And Acoustic Isolation From The Active Neighborhoods (Terraces, Parking Lots). 2. Technological Flow In Area A: Soil And Subsoil Washing (2,218 Ha) The Method Is Applied In The Sector Of The Former Coke Chemical Plant, Where Laboratory Investigations Have Revealed Severe Exceeding Of Intervention Thresholds For Uses Sensitive To Heavy Metals (Arsenic, Manganese, Lead), Sulfates And Petroleum Fractions. Phase A.1: Selective Excavation And Slope Support Phase A.2: Crushing And Granulometric Sorting Phase A.3: Aggregate Washing And Technological Water Treatment Phase A.4: Backfilling And Restoration Of The Site 3. Technological Flow In Area B: Isolation And Encapsulation (1,181 Ha) The Method Is Applied In The Area Of The Former Furnale Plant, Characterized By A Very Large Volume Of Physical Waste From Massive Demolitions (Large Blocks Of Reinforced Concrete, Underground Voids, Refractory Bricks). Phase B.1: Preparation Of The Support Layer Phase B.2: Realization Of The Impermeable Barrier Phase B.3: Execution Of The Upper Protective Structure 4. Management Of Hazardous Materials (Asbestos) During The Execution Of Excavations, Strict Attention Will Be Paid To Materials Containing Asbestos (From Former Cooling Towers And Industrial Insulation) 5. Quality Control And Monitoring Program Monitoring Compliance With The Ecological Targets Established By Order No. 756/1997 For Sensitive Uses Is Carried Out On Two Axes: • Soil Verification • Groundwater Monitoring All Operations Will Be Certified Through Monthly Reports Sent To Apm Hunedoara And Validated At The Final Reception By The Reception Commission. 6. Synthetic Indicators Of Geotechnical And Environmental Compliance In Order To Effectively Track The Results Of Decontamination, The Contractor Has The Obligation To Reach The Quality Targets At The Level Of The Matrixes
