The department said that many streets had become a mess during ongoing projects to bury overhead power lines and communications cables or to make repairs to water and sewage pipes.
It added that many contractors failed to clean-up roads or re-pave streets and pavements after digging.
Some also failed to set up barriers, creating risks for drivers and pedestrians.
Deputy Chief Inspector of the department, Nguyen Bat Han, said the Power Corporation had been told to restore roads and pavements back to their original condition after work finished.
Contractors ignoring the requirement would be strictly punished, he said.
The department has proposed the municipal People's Committee ban contractors with multiple violations from bidding for tenders in the city for up to three years.
By the end of the 2015 year, 400km of medium-voltage lines and 500km of low-voltage lines in the city's inner the city's districts 1 and 3 will have been placed underground.
The city hopes to have all power lines and communications cables in 14 other districts buried by 2020.
Lines and cables in administrative areas, commercial centres and new urban areas in the remaining districts would also be buried during the 2016-20 period, he added.
