Series Information
The first Survey of Construction Industry was conducted in 1993 with the assistance of Institute for Construction Training and Development (ICTAD). Thereafter the Department of census and Statistics continues to conduct the survey annually to cater to the needs of National Planners and other data users. The reference period for the 2006 survey report was 2005. The frame for this survey was the list of contractors registered with ICTAD.
Abstract
The Survey of Construction Industry was conducted in 1993 for the first time in Sri Lanka mainly to furnish data regarding input, output and their trends to the Institute for Construction Training and Development (ICTAD). The Department of Census and Statistics continues to conduct the survey annually to cater to the requirements of the data users along with the rapid development of the construction industry in Sri Lanka. However, due to the unsettled conditions, the survey of construction industries could not be fully conducted in Northern and Eastern Provinces. Therefore the data confines to the Provinces where the survey has been conducted.
In this survey, all construction activities undertaken by the private contractors who are registered with ICTAD, government and semi-government agencies are covered. Therefore, construction activities undertaken by the international contractors and the informal construction activities are not presented in this survey. Information is collected relating to the following sectors of the construction industry.
i. Building construction
ii. Highway construction
iii. Bridge construction
iv. Water supply & drainage
v. Irrigation & land drainage
vi. Dredging & Reclamation
vii. Other constructions
All construction activities, except building construction, mentioned above are categorized under Civil Engineering activities. The survey was aimed to cover 901 sample units in all provinces except some districts in northern and eastern provinces during the reference year 2005. The Department introduced a very simple questionnaire for the survey from the year 2000 considering the difficulties to obtain the information of construction activities.
The questionnaire was posted to selected contractors and followed up by sending reminding letters in order to collect information such as, value of contract, value of work done, value of raw materials used, salaries and other services.
Further employment statistics and value of subcontracts given by the main contractors are also collected. The list of contractors registered with the ICTAD and among those who were engaged in construction activities in the year 2004 have been used as the frame for this survey.
