asked the Secretary of State for the Environment whether any studies have been undertaken under the auspices of his Department since the Building Research Station document entitled " A Survey of Progress in House Building", published in July 1969, into the disparities between man-hours required to build public sector dwellings and those in the private sector; and, if so, what was the outcome of those studies.
The Building Research Establishment has carried out a further study of labour requirements for housebuilding based upon construction between 1967 and 1973. This was more extensive than the earlier study and particular care was taken to relate sample and results to the national pattern of housebuilding. I am sending a copy of the report, BRE Current Paper 76–78, to my hon. Friend. Copies of both reports are in the Library of the House.
