Private construction statistics from approved building permits relate to data on new constructions and additions, alterations and repairs of existing residential and non-residential buildings and other structures undertaken in all regions/provinces of the country.
Data processing of approved building permits is done both manually and mechanically. Copies of documents collected from the offices of LBOs are properly controlled, sorted, edited and coded, folioed and encoded in the PSA provincial offices. During machine validation, inconsistent and invalid entries which are flagged in an error listing are corrected in the data file. This process is repeated until there are no more inconsistent or erroneous entries found in the error listing. The data files are then forwarded to PSA Central Office for validation, consolidation and generation of preliminary tables. Data files received after the cut-off dates of submission set for each quarter are included in the generation of annual tables.
Preliminary results are based from data files that have undergone data processing in the provincial offices and have been validated at the Central Office. The preliminary tables are revised to include building permit documents received after the cut-off period in the annual tabulation.
Data is preliminary when first publish so are subject to revisions.
