We support the design process with regard to all environmental aspects. The evaluations we conduct apply both to the project stage and the subsequent operational stage, and may be supplemented by experimental measures and simulation calculations using dedicated software. Together with the environmental prefeasibility/feasibility studies and environmental impact studies, we also set out the subsequent environmental monitoring plans to control each and every stage of a project.

With regard to predictive simulations, we analyse noise, vibrations, air and electromagnetic fields, using instruments such as SoundPLAN, Caline, Calpuff, WinDimula and Magic. From an experimental point of view, we measure noise levels and vibrations in accordance with current regulations.

We provide support to public entities and businesses with the aim of preserving and improving the environment we live in.

Predictive simulations

Acoustic studies are carried out using the SoundPLAN simulation software to create horizontal and vertical noise maps and to map noise at façade level at the receptors and to make calculations on sensitive receptors. It is also possible to establish and design a series of noise mitigation measures to resolve any critical issues detected with regard to the regulatory limits established.

Predictive analyses are carried out using the proper instruments, selected based on the sources to be assessed: for linear noise sources, such as roads, the Caline software is used, while for aerial or particular noise sources, we use Calpuff (with a Langrangian model approach) or WinDimula (with a Gaussian model approach). The model produces colour maps of the isoconcentrations for the main pollutants and precise table values of those pollutants as calculated on discrete receptors.

MAGIC (MAGnetic Induction Calculation) software can be used to calculate the colour map of the magnetic induction generated by a series of conductors in which an arbitrary current is applied.

Environmental studies

Each phase of a project requires a detailed examination of the related environmental issues. The purpose of environmental pre-feasibility studies (for the preliminary project phase or the technical and economic feasibility project) and feasibility studies (for the final design phase) is to establish the expected impacts, starting out from the existing situation, and to design the pertinent mitigation and compensation systems. The environmental impact studies, necessary for some types of works, provide the key to determining the intervention required and the solution for integrating it into the environmental and territorial fabric it will be interacting with. A multi-disciplinary approach is used to directly and exhaustively determine the pressures regarding noise/vibrations/the air, taking account of the surrounding landscape and nature detailed in the Landscape Report and the Environmental Implications Assessment. Assessments are also conducted regarding the vulnerability and climate risk of the works.

Diapason Ingegneria supports the decision-making framework of Strategic Environmental Assessments, introducing considerations of an environmental nature into plans and development programmes to improve the overall quality of the planning process.

These involve establishing how environmental quality surveys are to be carried out, and the environmental matrices to be examined, as well as the monitoring stations for the aspects examined in the environmental studies and for which it has been possible to estimate an impact and subsequently define mitigation/compensation measures. The aim of the measures is to assess the initial conditions, the modifications expected while the works are being carried out and the situation after they have been completed, verifying the efficacy of the mitigation/compensation actions proposed and the actions for the recovery and restoration of the places compared to the initial conditions. The estimated bill of quantities for the proposed Noise Mitigation Plan is also determined.

Analytical methodologies are studied and designed to assess the environmental footprint of a product or service, taking account of the environmental impacts generated throughout its life cycle (from the raw materials through to production, distribution, use and ultimately disposal).

The AIA applies to the activities in the second part of Annex VIII of Italian Legislative Decree no. 152/2006 as amended, and requires the use of the Best Available Techniques (BAT) to reduce air, water and soil pollution, and waste production, as far as possible. Diapason Ingegneria provides support for the drafting of all the necessary documentation for the submission of the procedure to the regional authorities, or, for particular limits, to the Ministry of the Environment and Energy Security. The industrial categories it applies to include energy, production and processing of metals, mining products, the chemical industry, waste management and other manufacturing activities. The environmental authorisations that form part of the AIA regard emissions, authorisations for the discharge, disposal and recovery of waste, and other aspects of an environmental nature.

Plants not subject to the AIA measures, and specifically the categories of businesses mentioned in article 2 of the Ministerial Decree of 18 April 2005, must initiate a Single Environmental Authorisation procedure. For this procedure, to be submitted to the SUAP (the single business advisory centre), environmental documentation must be drafted regarding discharges, effluents, sound and air emissions, the use of sludge in purification processes and communications regarding waste.
