2. BWTPI is compiled by ArchSD in good faith to provide (i) an indication of the level of tender prices for new building works(excluding building services works) undertaken by the Department and (ii) an aid to adjust building cost data for estimating purposes. Separate tender price indices, known as Building Services Tender Price Index (BSTPI), are compiled for building services works.
3. Users of BWTPI should apply the index with prudence and should verify its accuracy or appropriateness for use in any specific circumstances.
