A recently published Aalto University research report (in Finnish) looks at waste in HVAC and electrical installations. The project measured the amount of non-value-adding time, i.e., waste, investigated its root causes, and developed ways to improve productivity.<\/p>\n

The researchers studied four Finnish construction sites. They collected data with hardhat video cameras, indoor positioning technology, interviews, and surveys.<\/p>\n

Unnecessary hurdles<\/h2>\n

The report paints an alarming picture of construction efficiency. The HVAC and electrical installation teams face challenges that make it almost impossible to be productive.<\/p>\n

The designs do not consider constructability, the general contractor\u2019s plans and schedules are superficial, the necessary information and communication are lacking, etc.<\/p>\n

No wonder HVACE workers used barely 20% of their work time for actual installations. They spent 18% of their time on entirely non-value-adding tasks. Of the remaining 62%, many of the activities resulted from poor communication, impaired logistics, and unnecessary movement.<\/p>\n

The following graph breaks down the workers\u2019 time for various activities during the research period.<\/p>\n

Tactics for a better future<\/h2>\n

The researchers suggested several tactics to improve productivity. A fundamental improvement would be to let those doing the installations participate in planning and design.<\/p>\n

Second, a logistics service should provide workers with material kits delivered on time to the exact location of the assembly. All the materials on the site should be stored \u201con wheels.\u201d<\/p>\n

Third, the use of HVAC prefabrication should increase, as is the case in the USA, UK, and Australia. Based on research done in the USA, prefabrication could improve productivity by 25%.<\/p>\n

The researchers also highlight the benefits of takt production. It enforces better planning and coordination of work and makes deviations visible at once.<\/p>\n

Finally, they remind us of the value of effective communication and how digital systems and tools can help the workers plan and manage their work and collaborate better.<\/p>\n
