All over the world the season is changing. The northern hemisphere is going into summer and the southern hemisphere into winter. Some regions are going into a time of heavy rainfall, others may experience cold and even snow, some will experience heat, while others could face the threat of storms which could bring hail, wind or lightening.
So is your construction project ready for the changing season?
In the northern hemisphere many are packing away their cold gear after a prolonged winter, which has often hampered production, and they are now looking forward to some sunshine. But are you prepared to make the most of the good weather before the season inevitably, and often too soon, changes again?
So why do we need to be thinking about the changing seasons?
Changed weather conditions can have a big influence on safety.
Heat brings the risk of heat exhaustion and bush fires.
Dry conditions increase the risk of bush fires, dust and a shortage of water for construction.
Wet conditions pose flood risks, slippery conditions on walkways and roads. It can also make project access roads impassable and ground conditions could become soft, even resulting in cranes toppling should their outriggers settle in the softer ground. Sides of excavations may become unstable and buildings could become undermined.
Wind creates dust, flying debris, unsafe lifting conditions for cranes and the risk of poorly stacked materials being blown over. Partly completed structures could be toppled in high winds. I’ve even had people blown off their feet into excavations or off access platforms. Cranes can be blown over.
Storms bring lightening, heavy rain and high winds which cause damage to buildings and injury to people.
The changing season could also bring a decrease in the hours of daylight which could reduce construction productivity and cause safety concerns. Even the changed position of the setting sun could make driving conditions unsafe on some site access roads.
During poor weather production may be slowed or even have to stop for safety reasons. Construction materials may not be lifted in high winds.
Workers have to take more frequent rest breaks when working in extreme temperatures and their movement could be hampered by cold weather or rain clothes.
Concrete could take longer to set and reach sufficient strength to strip forms, while in hot conditions there could be the risk of cold joints forming.
Equally important is to review procedures and set new targets when weather conditions improve. Often people become used to doing tasks in a certain manner, taking numerous breaks as required by the weather conditions and achieving certain targets. When weather conditions improve they continue to do the tasks as done to suit poor weather conditions without modifying their actions to achieve the better productivity they should in the good weather conditions.
Damage to the work
Stormwater can flood excavations, damaging equipment, cause excavations to collapse and generally delay work.
Rain can penetrate partly completed buildings damaging finishes and equipment.
Dust can enter equipment and damage it.
High winds can tear away objects and materials not fully installed.
Stormwater flowing from the construction site can erode away neighbouring properties or deposit silt or contaminated material from your project site onto neighbouring properties.
Dust created by the construction work could be blown onto neighbouring property, causing damage, irritation and a safety hazard.
Heat, wind and cold all impact curing of concrete.
Some materials can be damaged when exposed to extreme heat or cold, or if they get wet or covered in dirt.
So what can we do to prepare our projects for the new season?
Over and above the changing seasons there seem to be more freak weather events. How prepared is your project for sudden and unexpected ferocious weather events? Well we can’t be prepared for all of these, however, it may be worth thinking about them, and at least formulating an emergency plan in case your project is about to be hit by a freak storm.
Is your construction project ready for the new season’s opportunities and challenges?
