Follow up - from planning to operational status


Created in 2008 within the Grillo-invest holding company, G-invest is engaged in the study and management of projects entrusted to our sister companies.

Thanks to the expertise of our engineers and CAD designers, we offer our customers a high quality service covering all project stages, from initial study to site supervision, in the construction of steel structures, pipelines and boiler works.

Our engineers are also there to co-ordinate your sites, however large they are.

We have recently invested in several new software tools such as Autocad Plant, allowing us to further expand our scope.

Placing your trust in G-invest brings the assurance of unparalleled service from first contact to the end of construction.

Our procedure


Our experienced team, bringing together designers and engineers, allows us to cover all your industrial projects from start to finish, according to an optimal procedure.

This method starts from our first meeting, with the preparation of budgeted preliminary studies, leading to a full quote.

Once the quote is accepted, we perform a thorough study of your requirements and prepare comprehensive tender specifications in order to ensure the project proceeds seamlessly. We then envisage and detail all the procedures you will require.

Once construction has started, we regularly conduct on-site monitoring and coordinate all site progress. This approach ensures the success of your project.
