Mezzanine Structural Assessments

Our structural engineers are frequently asked to carry out structural assessments of existing mezzanines. These are often needed to confirm load capacity and define recommendations for the management of the mezzanine. This information allows our clients to decide how the area should be used.

Often, we are asked to carry out a structural review by clients who are planning to change how they use the mezzanine, for example after a company expansion or change in ownership.

Often, we find that additional shelving or equipment can be safely added, allowing our clients to maximise the use of the space. In other instances, we have found mezzanines that have been built without any apparent structural design being undertaken first. In these cases, we have been able to advise on measures to increase the stability of the construction and improve the safety of the structure.

Our chartered structural engineers can also be engaged to carry out structural appraisals that are stipulated by mezzanine management schemes. These are voluntary schemes, most frequently used for mezzanines that do not comply with the imposed loading requirements specified in BS 6399 Part 1. This does not mean that the mezzanines are not safe for their current use, but instead, these schemes are used to give building owners the flexibility to use designs with a variety of operating limitations and minimum imposed loads. Typically, this type of appraisal is carried out every 3 years.

Our mezzanine capacity assessments include reviews of dead loads, imposed loads, the capacity of existing structural elements and a review of current loading. Lateral stability is also assessed, and fire protection measures are considered.

Importantly, if the mezzanine has been extended or altered, different calculations should be carried out for each distinct area.

Our assessments are done against the requirements of BRE Digest 437 Industrial platform floors: mezzanine and raised storage (and associated current structural codes of practice), which sets out requirements for loading, structural form and stability of lightweight mezzanine floors.  We also include recommendations for a voluntary Management Scheme in line with the guidance set out in BRE Digest 437 to ensure that the safe operating limitations are fully appreciated by the building owners and users.

The findings or our inspection are presented in a report complete with supporting calculations to justify the load capacity, appended to the document for future reference.
