Although annual shutdowns are not legislated as compulsory, Lydia stresses that it is best practice in risk management when assets are serving critical systems of the organisation, or in ageing buildings.
“It’s the same as when you’re changing the engine oil or fixing a flat tyre. Even though your car is able to drive for a while, you know you’re doing it to allow for optimal performance, to avoid costly repairs later on and you’re gaining a lot in efficiency and safety at the same time.”
Lydia provides insights into the most frequently asked questions relating to complete facility shutdowns:
Medium voltage (MV) switchgear and transformer upgrades are the only services that would require a full shutdown to affect maintenance upgrade and major repairs. A complete facility shutdown is not necessarily to affect maintenance but is advisable to test the critical interconnected systems that serve the building. During this time, the equipment capacity should be tested, and the related maintenance interventions identified to ensure the ongoing stability and safety of the building systems – necessary in the event of total blackouts or fire in a building.
Other typical systems that should be tested during facility shutdowns include fire systems, lifts, emergency lighting, back-up power capacity, HVAC extract system to name a few. Most assets have guarantees and warrantees that stipulate maintenance conditions and frequency of maintenance servicing to ensure its reliability and longevity. This could range from monthly to once a year – or in some cases at a three-year interval, depending on the type of asset. The frequency usually specifies the type of maintenance that is required, but it is vital for these maintenance and servicing tasks to be done in order to uphold the terms of the guarantee.
Some of these assets often form part of (or are interdependent with) other critical systems that aid the overall safe function of a building. For example, smoke detectors are linked to a fire panel and a building management system that sends warnings when emergency intervention is required. Failure to service and test the links to this panel could result in critical communication being compromised and ultimately lack of response to these alarms would result in serious losses if not attended to.
Reinstating systems when contractors attend to their side of maintenance is often the main reason for system failure and in most cases found after an incident has occurred.
What are some of the safety requirements that need to be taken into consideration (and be complied with) during such maintenance upgrades?
Risk assessments and safety task analysis should be a standard process in place that should be enforced when embarking on a full shutdown of the power. Typical risks linked to a shutdown are that the entire building will be in complete darkness and therefore synchronising and step-controlling the process with contractors responsible is important to ensure the safety of the teams responsible for the tests.
When it comes to testing fire systems, the safety of company assets should never be overlooked. This includes release of escape doors and their operation to ensure safe evacuation. For the same reason, a company’s security staff (technical and non-technical) should be reminded to also regularly check that these automatic doors are open for evacuation. Their presence at these exit doors are important to monitor and secure the building during the test phase.
Our safety systems support these activities. Furthermore, we have set procedures for such documented and critical systems highlighted and scheduled right from the inception of contractor engagement. We execute and implement maintenance programmes in accordance with project management principles and measure and manage all risks on behalf of a vast amount of clients we provide this service for. In agreement with our client, these tests are planned, communicated and executed.
The planning and preparation of a shutdown should be coordinated by a senior technical manager or project manager in the FM team. Shutting down the power to the building will have an impact on the entire business and all stakeholders should therefore be considered and consulted – especially infrastructure and IT as they are responsible for business support systems – the life-blood of any organisation, so they are directly impacted. In the case of shopping centres, retailer engagement is critical as they have to shut down their own interdependent systems and be on standby to switch systems back on when power is restored. As mentioned earlier, it is important to also coordinate with security to avoid ingress and egress of anybody who is not involved in the shutdown.
The practice of shutdowns is often ignored because it can be disruptive as it comes at cost of service provider time and core business down time. However, the value of doing these shutdowns is negligible if you consider the damage that can be caused if important maintenance tasks are not regularly performed (the damage caused at Parliament’s House of Assembly after a fire extinguishing system failed to kick in timeously, is a sad and telling example).
FM Solutions has the expertise and experience to coordinate and manage complete facility or system shutdowns, keeping cost and disruptions to a minimum. We develop an affordable and manageable preventative maintenance plan for each client, whilst also developing fit-for-purpose rectification plans to address high risk maintenance – based on the findings of the shutdown. We partner with our clients by assisting them with life-cycle costing and valuable data for a streamlined maintenance budget.
