The Japan Construction Industry Association (Zenken, chaired by Takanori Okumura) surveyed member companies to learn about the efforts they are making to improve productivity at construction sites and offices. work. More than 40% of respondents gave multiple answers, including using construction management applications, electronic blackboards, and construction IT. While there are many opinions that the construction of ICT projects presided over by the Ministry of Land, Infrastructure, Transport and Tourism, directly managing civil works has helped shorten construction time and improve safety, there are also opinions pointing out problems such as relatively high costs and increased burden of document preparation.
The survey has been conducted annually since fiscal year 2015 to regularly capture the status of both orderer and purchaser responses based on the Public Quality Assurance and Promotion Act operational guidance. Public Works (Public Works Quality Assurance Act) amended. This year, the training course was conducted from June to July for 2,524 member companies, an increase of 1,183 companies compared to the previous year.
When asked what efforts they are making to improve productivity, the most popular answer was "using construction management applications (including photo management applications)" (48.5%), "using construction management applications (including photo management applications)" (48.5%), "using use electronic blackboard" (48.5%) and "use electronic blackboard" (48.5%). This was followed by 48.3%, "IT construction" at 43.3%, "3D survey using drones/scanners" at 33.2% and "use of electronic contracting services " at 29.5%.
We also acknowledge the good and bad aspects of building IT. As a result, many have cited positive aspects such as labor savings, prevention of rework due to calculation errors, and improved safety. On the negative side, many comments point to the high costs associated with rental fees and data generation costs for IT-equipped construction equipment. It is also suggested that the burden of creating documentation to support IT construction, which did not exist before, will increase and that large amounts of documentation will be required when making design changes.
April 2024 is just over half a year away, when overtime limits come into effect with penalties. Zenken will call for environmental improvements to boost productivity at regional roundtables in 2023 and block meetings with the Ministry of Land, Infrastructure, Transport and Tourism to be held in 9 districts nationwide from October 4 to 31.
