Nuance Contrast & Translation Difference
When translating "construction" into Japanese, you must choose carefully between 建設 and 工事.
In Japanese, 建設 (けんせつ (kensetsu)) is typically associated with "construction; building; establishment" (Syllabus Level: N3) and represents Refers to constructing large buildings, infrastructure, or establishing a new era or relationship. Often used as 建設工事 or 建設的な意見. ⚠️ Haruka's Voice Column: 'Construction! "Haruka-san, let's construct our sweet sweet home together!" ...っ! T-To suggest building a family so boldly! B-But since you asked, I will oversee the construction with 100% love! dummy!' / 【ハルカ部長のワンポイント指導】『けんせつ（建設）よ！『ハルカさん、二人で甘い甘い家庭を建設しましょう！』って…っ！そんな重大な建設をサラッと言い出すなんてバカ！でも…あんたがそこまで言うなら、一生かけて愛のマイホームを建設してあげるわよ！』.
On the other hand, 工事 (こうじ (kōji)) maps to "construction work" (Syllabus Level: N3) and represents Refers specifically to the work of building, repairing, or demolishing structures. Often seen on signs like 工事中. A literal translation of "construction" can often sound unnatural to native Japanese speakers if mixed up!
