Enhancement of Tender Evaluation Framework to improve Construction Productivity

Since 2001, BCA’s mandatory Buildability framework has encouraged more labour efficient building designs and is one key contributing factor to improving site productivity. In 2011, the framework was enhanced to include the constructability requirements to steer builders towards adopting more labour-efficient technologies and methods to improve productivity at the construction stage.

To nudge the industry to adopt labour saving solutions in construction to reduce the need for manpower usage at site, BCA has enhanced the tender evaluation framework for public sector projects with the aim to improve construction productivity by recognising consultants and builders who have achieved higher buildability and constructability in their projects. Under this framework, the Buildable Design Score and Constructability Score would be introduced as mandatory quality attributes when evaluating tenders under the Quality-Fee Selection Method (QFM) and Price Quality Method (PQM) frameworks respectively with effect from 15 July 2013.

The new quality attribute will account for 15% of the total quality points to emphasise the importance of productivity improvement moving ahead. The scoring will be based on an index, namely the Buildable Design Score Index (BS Index) in the case for QFM and the Constructability Score Index (CS Index) in the case for PQM. These indices are calculated from the firm’s latest completed projects (up to maximum 5) during the last 3 years. The firm with the highest BS/CS Index among all the tenderers will get the full 15 points out of the total 100 quality points, while the rest of tenderers’ scores will be pro-rated against the highest index accordingly.

The details on the above productivity initiative were shared through briefing sessions held for the industry over 3 sessions on 28 July 2011, 24 Aug 2011 and 12 Sep 2011. The briefing slides are available below for information.

LIST OF BUILDABLE DESIGN SCORE (BS) INDEX FOR CONSULTANCY FIRMS

BS Index is derived based on each design firm’s as-built Buildable Design Scores for that discipline achieved for the latest completed projects (up to a maximum of 5 projects) in the last 3 years. It is computed based on the following methodology:
