Kevin Myers, the HSE's chief construction inspector, launched the programme on Monday at Ashburton Grove in north London, where Arsenal Football Club are building a stadium.
He said four construction workers had been killed in the past two months from falls or after being hit by a vehicle or a load. He added that none would have occurred if more effective safety procedures had been in place.
Myers said: "HSE inspectors will visit construction sites to help reduce the unacceptable toll of construction deaths."
Health and safety commission member Hugh Robertson said the construction industry was a priority area. He said: "The industry contributes a major share of fatalities and serious injuries in workplaces because of its size and its poor health and safety performance." He said the industry had to take a lead in cutting the risks to employees.
There were 73 deaths in the building industry in the year to March, according to provisional figures.
