Business Policy

Productivity Increasing Initiatives Contributing to Growth of an Attractive Construction Industry

Given the worries about a shortage of skilled workers in future, increasing productivity is the biggest challenge for the construction industry if it is to continue developing sustainably. Obayashi will of course enhance safety and quality by developing and acquiring advanced technologies. We will also work to reduce overburden, waste, and unevenness at construction sites, strongly promote work style reform, and contribute to the growth of an attractive construction industry. We will also work to maximize earnings for the Group as a whole by responding flexibly to changes in the market.
