The Critical Role of Drainage Inspections in Rerfurbishments
As part of a wider refurbishment project, we were instructed to conduct a drainage inspection in Shirley for our established client, Orchard.
Refurbishments can significantly boost asset profitability by increasing rental income, attracting higher-quality tenants and adding long-term value.
However, if there are unaddressed issues within the drainage system, it significantly increases the risk of unexpected problems arising. These usually result in costly repair work, operational disruption and asset damage – all of which undermine profitability and ultimately compromise the objectives of a refurbishment.
Our Findings
In this case, the drainage system was found to be in good overall structural condition, with no major drainage repairs identified. However, we did discover some blockages and accumulation of silt and debris.
As this drainage system in Shirley had been well maintained, only minimal and low cost remedial work was required. This included high pressure jetting to remove the silt and debris from the system and restore the full capacity.
Summary Points
Compared to some of the serious defects we often uncover during inspections, these were relatively minor. However, without an inspection, they would have gone unnoticed – potentially escalating into more significant problems which could adversely affect the intended return on the refurbishment investment.
The human eye cannot see what is going on beneath the surface which is why regular inspection is crucial to detect issues before they escalate. Drainage problems rarely show visible signs until they become severe – such as surface water flooding or back-flow – and are expensive and disruptive to resolve.
Additionally, unaddressed drainage liabilities can lead to environmental breaches and legal non-compliance issues which may only be realised when the landlord or tenant receives a (potentially substantial) fine. It can then be costly and disruptive to rectify these issues, and also damage the reputation of the property owner or tenant. This will further undermine the aim of a refurbishment.
Relying on the assumption that the drainage system is in good working order is a risk.
The potential costs – financial, operational and reputational – make speaking to a drainage consultant a smart and proactive step to mitigate risk, safeguard assets and protect investment.
