Summer represents for many industries one of the few opportunities of the year to perform inspections, reorganize layouts, replace machinery, or catch up with regulations. With reduced activity or even scheduled technical shutdowns, this planned downtime, usually from one to four weeks, allows in-depth actions to be carried out while minimizing the impact on regular production.
However, everything depends on prior planning. If left for the last minute, resources overlap, spare parts don’t arrive on time, technicians are on vacation, and what should have been a coordinated process turns into a race against the clock.
In this article, we review the main types of maintenance that can be carried out in summer, the benefits of planning them in advance, and some best practices to ensure everything flows smoothly without surprises.
And if you are preparing a technical shutdown this summer, we’ve created a practical template that can make your work much easier.
It includes:
- The key planning items, depending on the type of intervention(s) to be carried out, so nothing is left out.
- An editable Excel to organize and schedule resources according to the work to be performed.

What type of maintenance do industrial plants need in summer?
Every company is different, but there are four types of actions that repeat year after year. At Gurpea, we are not only prepared to execute them but also to help you plan them, provide resources, coordinate them, and complete them successfully within the established timeframe.
1. Planned preventive maintenance
Inspections, deep cleaning, part replacements, adjustments… Everything that could not be done during the year due to lack of time or production pressure. It is the ideal time to ensure that critical equipment enters the next production cycle in good condition.
2. Reorganization of production layouts
Many companies use the shutdown to adapt layouts to new products, automation, or expansions. This requires prior analysis, technical design, and coordination of different trades to move and install equipment.
3. Individual machinery movements
Whether to incorporate new machines, renew robots, or move sold or unused equipment, these operations usually take place during the summer weeks. The logistical complexity makes good planning even more important.
4. Compliance with RD 1215/97
The summer shutdown is also used to make adjustments required by regulations such as RD 1215/97, which establishes safety conditions for the use of work equipment. Having certified technical personnel for these interventions is essential to comply without delays or risks.
Why early maintenance makes all the difference
Planning maintenance in advance not only brings peace of mind—it directly improves operational and financial results. Some data show this clearly:
- Preventive maintenance can **reduce costs by 12% to 18%** compared to corrective maintenance.
- Every euro invested in scheduled maintenance can **save up to five** in future repairs.
- Companies that have implemented predictive maintenance have **reduced unplanned downtime by up to 91%** (PwC).
- Unplanned downtime represents **11% revenue loss** in large industrial companies (Siemens).
Over the long term, this type of planning also extends the useful life of equipment, avoids premature investments, and reduces energy consumption. It is an investment that pays for itself.
Best practices for effective summer maintenance
Organizing a technical shutdown in summer requires method, foresight, and execution capabilities. Many factors must be considered to ensure everything goes according to plan. The good news is that, although these elements are critical, the company itself does not have to bear the entire planning and coordination burden. That’s what we are here for.
These are some of the keys that allow a summer intervention to be carried out efficiently:
-
Anticipation—always:
Before the holidays arrive, it’s advisable to perform a thorough assessment of the facility’s condition. This involves conducting evaluations and diagnostics to create a list of necessary interventions during the shutdown. That list should include both preventive maintenance tasks (scheduled to prevent failures) and pending corrective actions (repairs of breakdowns or defects accumulated throughout the year). The more comprehensive the list, the greater the organization required to complete everything on time.
-
Consider workforce and production rhythms:
Planning must take into account both staff vacations and any residual plant activity. Adapting to this reality is essential so interventions fit without creating friction.
-
Early coordination of technical personnel and suppliers:
Summer maintenance often mobilizes the entire maintenance team and requires multiple technical profiles, especially in industries like automotive and metalworking. It is important to plan staff availability (internal and contractors) in advance, considering vacation periods. Many companies hire specialized external support during these weeks to ensure all scheduled work is completed.
-
Define the scope and resources for each task:
It is essential to prepare a detailed maintenance program, specifying, for example, the estimated duration of each task, required labor, materials, spare parts, tools, and an associated risk assessment. Each job must have the necessary resources available on time; therefore, it is advisable to develop a logistical plan in advance to receive and store spare parts.
-
Prioritize health and safety:
Summer heat and the intensive nature of many maintenance tasks require special attention to safety. Work must be coordinated so the conditions are as safe as possible: for example, checking ventilation and A/C systems before and during the shutdown, scheduling heavy tasks during cooler hours when possible, keeping workers hydrated and protected, etc. According to the WHO, indoor environments should not exceed 32°C during the day (24°C at night).
-
Take advantage of reduced activity for in-depth tasks:
In many sectors, summer means lower workload or lower demand, reducing production pressure and making inspections and repairs easier to perform thoroughly. This “extra time” should be used for comprehensive inspections of critical equipment (such as high-wear machinery like ovens, conveyors, cranes, etc.), identifying wear, corrosion, or other hidden issues. It is also the ideal time for deep cleaning of areas difficult to access during normal operation (ceilings, pits, ducts), removing accumulated dirt that could affect safety or performance. All these preventive actions increase safety and help avoid major breakdowns or accidents by ensuring the good condition of critical installations and equipment.
-
Plan for unexpected events:
A last-minute absence, a spare part that does not arrive, or a machine that is more troublesome than expected… Unexpected issues happen. Having alternatives prepared prevents a minor incident from derailing the entire plan.
-
Training and certifications up to date:
Some interventions require personnel with specific accreditations (e.g., work at height or confined spaces). Ensuring that technicians have the required training—and proper documentation—avoids delays and guarantees project safety.
-
Review future production needs:
Another good practice is to anticipate next year’s needs. If an increase in demand or an intense post-summer campaign is expected, equipment should be prepared during the shutdown for this future activity spike. For example, if the company knows it will launch a new product or increase production at the end of the year, summer is the ideal time to adjust machines, add capacity, or reinforce components to avoid future bottlenecks. Maintenance planning must align with future production strategy.
Ultimately, the success of a well-executed technical shutdown lies in the details. And when someone is responsible for orchestrating all of them, the process becomes much easier for the company requesting it.
And after the summer… maintenance continues
Although the summer shutdown concentrates many actions, maintenance should not be understood as something occasional. Regular preventive tasks and corrective actions continue throughout the rest of the year, and it is advisable to have a continuity strategy: scheduling inspections, updating inventories, analyzing data, and anticipating potential failures.
Having flexible technical support throughout the year—whether to cover an absence, reinforce a shift, or respond to an emergency—can make all the difference when production pressure increases.
Strategic planning: foresight and resources
Summer is an opportunity to maximize the operability of facilities. If planned with foresight and with the right resources, summer maintenance becomes a strategic investment that translates into reliability, savings, and competitiveness for the company.
If you still haven’t defined your maintenance plan for this summer, now is the time.
