Methodology

To properly evaluate the roof structures of CDM, a team from Royal HaskoningDHV travelled to Beira for a kick-off meeting with CDM and a 2-day guided site visit through the whole brewery.

The kick-off meeting was vital to understand the concerns of CDM regarding the condition of the buildings and what they expected from this inspection.

A representative of CDM guided the RHDHV team composed of a structural engineer and a mechanical engineer while visiting all buildings (except the residences which are not being used due to their degrading state) and inspected the roofs from the inside of each building and from the outside. The inspection outside the building was done using a drone as most roofs were not accessible. The drone made it easier to inspect the gutters, considering that almost all buildings suffer from water infiltration.

Although the purpose of the visit was to inspect the roofs, CDM also expressed concerns about the cracks on the walls during t he kick-off meeting, hence RHDHV also conducted a high-level inspection of these elements.

The inspection included the identification, registration and diagnosis of anomalies that occurred. The anomalies were observed and classified, in order to assign a classification to their state of conservation and maintenance. A general classification of the roof was attributed for each building.

Special attention was paid to Pack Hall, Un/Loading Bay and Old Cellars buildings as these were the most affected.
