    • Inspections of that structure are carried out periodically by competent persons in order to render the structure safe for continued use;
    • That the inspections contemplated in paragraph (a) are carried out at least once every six months for the first two years, and thereafter yearly;
    • The structure is maintained in such a manner that it remains safe for continued use;

    Mounted Solar PV Projects

    Structural Engineering is a small but critical part of the engineering for a rooftop solar project. It can make or break the feasibility of the project, or have significant effects on the system size and cost of racking.

    During the past 5 years, SiVEST has conducted more than 160 roof studies for a range of clients in various sectors. Our aim is to supply the client with an objective report that covers the condition of the sheeting and substructure, as well as the structure’s ability to support the additional load.

    Our methodology includes the following steps, however, these differ from building to building:

    • Site assessment to record the condition of the structure and sheeting, types of materials, structural member sizes and roof geometry.
    • Capacity calculations based on information gathered during the site investigation.
    • Report regarding the findings, recommendation and photo records.

    Our reporting will not only portray the amount of acceptable additional load, but should a roof has limited capacity, SiVEST will make recommendations to spread the load over certain areas, or suggest remedial works in order to increase the structure’s capacity.

    SiVEST has a team of Professionally Registered (Pr.Eng.) Structural Engineers who fulfil this requirement, and can carry out these inspections to assist our clients to get a clear understanding regarding the condition and capacity of roof structures and cover. Our team has carried out these studies for a variety of clients in the Public and Private Sectors for industrial, commercial, health, educational and residential buildings.
