Inspectors from the Health and Safety Executive are assessing refurbishment sites across London as part of a two-week long initiative.
They will be focusing on safe working at height, good site order and will be taking enforcement action against contractors, which fail to meet their standards.
"The level of fatal accidents in refurbishment work in the construction industry is just not acceptable," said Barry Mullen, principal inspector for London.
"More can be done and should be done to improve safety standards. We will be checking these standards and taking strong action where appropriate."
Provisional figures from the executive for 2006/2007 showed that ten construction workers died in the capital.
During this period, there were a further 1,956 major injuries and 34 members of the public were also harmed.
Inspectors will be keen to see that equipment is correctly installed, inspected, maintained and used properly and that sites follow correct reporting procedures.
Offices and workplaces also have health and safety policies, which cover risk assessment, use of IT equipment and workplace hazards.
