Lavori di realizzazione di un impianto di digestione anaerobica per il trattamento della frazione organica dei rifiuti urbani nel comune di teramo. Affidamento congiunto dei servizi di progettazione esecutiva comprensiva del coordinamento per la sicurezza in fase di progettazione, e dell'esecuzione dei lavori (ai sensi dellart. 44 Del d.Lgs 36/2023)

The contract timeline involves several phases with specific durations, but no explicit fixed start or end dates are provided, rather durations from specific events. The contract is anticipated to be stipulated in the year 2026.

Key durations and phases are:

• Executive Design Phase: The useful time for completing and delivering the executive design, including any improvements offered, is 60 natural and consecutive days. This period begins from the date of contract stipulation or from the early service delivery report.
• Work Execution Phase: The useful time for completing all works included in the contract is 324 natural and consecutive days. This period starts from the date of the work delivery report.

Other mentioned phases and milestones include:

• A "Cronoprogramma" (timeline) will detail all implementation phases, including the executive design, project approval, work assignment, work execution, and final testing or issuance of the regular execution certificate.
• A "Fase di avviamento" (start-up phase) is mentioned.
• "Fase 2" refers to support and training services, measured by KPIs and concluded with a "Verbale di chiusura affiancamento" (accompaniment closure report) upon achieving defined KPIs.

The total duration of the entire contract is not explicitly stated as a single sum but can be derived from the durations of the executive design and work execution phases. Contract start and end dates are not stated as fixed calendar dates.

The core scope of work for this tender involves a comprehensive range of activities across several major categories, aimed at delivering a complete and functional project. The statement of work summary encompasses the following key areas and deliverables:

1. Structures: This includes works related to external areas, service networks (such as crossing points, first rain collection, water accumulation, and pipe racks), a treatment shed (including external paving, fences, process water and drainage networks, civil black water networks, and prefabricated structures), a biofilter and storage shed (including prefabricated structures), a purifier room (paved areas, green areas, purification systems, and tanks), offices and control room (green areas and external paving), and various external structures.

2. Civil Works: This category covers similar elements to structures but with a focus on civil construction aspects, including external areas (paved areas, green areas, external paving, fences, and prefabricated structures), a treatment shed (including fixtures and finishes), a biofilter and storage shed (internal paving), a purifier room (internal paving), offices and control room (fixtures and finishes), digestion and external technical areas (anaerobic digestion), and morphological arrangements (paved areas and roads).

3. Electromechanical Works: This significant portion of the work includes the supply and installation of machinery and equipment. Key deliverables here are treatment machinery, anaerobic digestion systems, biogas valorization systems, and aerobic maturation systems. Specific machinery mentioned includes a pre-treatment, mixing, and screening section (bag opener, overbelt magnet, dosing/reception tank, rotary drum screen, green shredder, mixer), and various transport systems (conveyor belts and augers).

4. Subservices and Electrical Systems: This covers various networks such as those for process water, civil black water, purified water discharge, ingestate/digestate lines, rainwater, and the overall electrical system.

5. Other Key Deliverables:

• Capannone prefabbricato (Prefabricated Shed): Construction of a prefabricated shed, including specific concrete and reinforcement specifications.
• Depurazione (Purification): Implementation of a purification section, including screening, homogenization, biological section, ultrafiltration, reverse osmosis, reagent dosing, and storage tanks for concentrate and purified water.
• Cogeneratore (Cogeneration Unit): Installation of a cogenerator with specified electrical power (500 kWe nominal), electrical efficiency (41.1%), thermal power (307 kW), and noise/emission levels. This also includes a biogas upgrading section with pre-treatment, upgrading, compressor, measurement cabin, piping, electrical connections, and control system.
• Air Treatment Network: Installation of an air treatment network, including aspiration network and scrubber.
• Antincendio (Fire Protection): Fire protection systems.

The overall project has a total cost for works of €29,371,751.69. Additionally, there are sums available for direct administration works (e.g., mechanical shovel supply), IT management services, utility connections, land acquisition, environmental surveys post-remediation, demolition of the former incinerator, archaeologist assistance, publicity, acceleration premium, technical functions, preliminary design and works supervision, executive design and safety coordination, technical-administrative and static testing, support for verification and validation, support for VIA-VAS (Environmental Impact Assessment - Strategic Environmental Assessment), SCIA VVF (fire prevention certification) expenses, cadastral registrations, social security contributions, and contingencies.
