Description of the job
- Asbestos removal and reconstruction of the building's roofing
- Installation of a photovoltaic system
Our client decided to install a crystalline silicon photovoltaic system on the curved roofing of their Cologno Monzese offices.
First of all, asbestos was removed and disposed of and a new corrugated sheet roofing was installed, on which the photovoltaic modules were fitted. Because of the curved shape and the exposure of the roof, the modules had been installed on the top part only, to optimise productivity (see picture). A permanent life line was installed to complete the works.
Technical data
- Removal of 1,025 m2 of cement-asbestos
- Roofing reconstruction with 8/10-thick corrugated sheets and 50 mm mineral wool insulating mat
- Installation of 406, 245 W poly-crystalline silicon photovoltaic modules
- Power of the photovoltaic system installed: 100 kWp
- Estimated return on investment time, including remediation and roofing reconstruction: 5 years
- Work duration: 2 months

Description of the job
- Asbestos removal and reconstruction of the building's roofing.
- Installation of a photovoltaic system
The Quinto di Treviso plant is an industrial building with non-walkable shed roofing. The interventions included first of all the removal of the two-layered asbestos from the roofing. For safety reasons, safety nets had to be installed on the entire surface. The roofing reconstruction included the installation of pre-painted galvanised-steel sandwich panels with 50 mm mineral wool insulating mat, as required by the new fire brigade regulation. A permanent life line was installed to complete the building operations.

Description of the job
The reclamation of the former Valtanaro dyeworks which currently hosts the new Miroglio logistic centre, required asbestos-removal work on machinery, pipes and roofing. Tecnologie Industriali & Ambientali carried out the asbestos and mineral fibre removal operations, but also mechanical demolitions and re-roofing on a surface of approx. 17,000 m2.
Interventions were carried out on:- some dying machineries containing friable asbestos mainly in their gaskets. A static-dynamic confinement was required
- pipes of approx. 11,000 ml coated with mineral wool
- cement-asbestos roofing 17.000 mq.
- machineries, tanks, silos, brackets and pipes
The intervention also included the selective sorting of waste materials (mineral wool, steel, aluminium, electrical cables, etc.), iron recovery and disposal of materials in authorised landfills. The roofing reclamation was carried out on a surface of 17,000 m2. The reconstruction included:
- steam barrier recovery
- installation of new insulating systems
- installation of new roofing
- eaves waterproofing
- installation of new pitches
Critical points
In order to respect the timing set for the reclamation of the whole complex, demolition, remediation and reconstruction works were carried out in only 6 months. This required a huge organisation and coordination work.
Amount of the contract: € 900.000

Description of the job
Inspection and evaluation of the state of conservation of asbestos-containing materials (ACM) and man-made vitreous fibres (MMVF), that are present in different areas of the ILVA plant in Taranto, in order to carry out a risk assessment.
- inspection of the working areas to assess the state of conservation of asbestos-containing materials, already known and listed, the presence and the state of conservation of asbestos-containing materials and the presence of MMVF (man-made vitreous fibres)
- assessment of the risk of exposure to airborne asbestos fibres and man-made vitreous fibres, by means of sample-taking and analysis by scanning electron microscopy (SEM)
- preparation of the inspection and assessment report, photographic documentation, sample analysis certificates and assessment of their results, including samples of materials which may contain asbestos
In particular, our intervention included:
- Installation of 2 office containers and storage for equipment and PPE
- Samples were taken and sent to the Accredia accredited laboratory, to be analysed by Scanning Electron Microscopy (SEM), certificates were issued for the analysis of airborne fibres and large samples of materials which may contain asbestos
- Samples were taken and sent to the Accredia accredited laboratory, to be analysed to determine the average diameter of alkaline oxides and alkaline/earth oxides, certificates were issued for the analysis of large samples of MMVF (man-made vitreous fibres)
- Assessment of the state of degradation of ACM by means of the methods required by applicable regulations (VERSAR)
- Preparation of a final document for each area, including the inspection report - photographic report - application of methods to be used for the evaluation of the state of conservation of ACM by means of the methods required by applicable regulation - Plans identifying the sampling points - Analysis certificates - Tabulation of results
