PAS 91: 2013 replaces PAS 91: 2011. It provides a set of questions that can be asked by construction clients and buyers of potential contractors and suppliers as part of the pre-qualification process for construction projects.
PAS 91 is aligned to the Government Construction Strategy, contributing to the target of achieving savings in construction costs of 15-20% through the reduction of tendering costs, and is set to be mandatory for Government projects from 2016. Seen as a significant improvement on the 2011 version, it includes questions to examine competence in Building Information Modelling (BIM) and collaborative information exchange in preparation for the Government 2016 BIM mandate (requiring fully-collaborative 3D BIM on public projects with project and asset information, documentation and data being electronic, as a minimum).
Once suppliers have completed one PAS 91 questionnaire, the same set of standard responses can be used by all buyers who are PAS 91 compliant. The format also allows suppliers to share their PQQ responses with other clients and buyers through PAS 91 online portals. PAS 91 could therefore be seen as a suppliers real-time portfolio of capability and as such, it requires constant updating to ensure that responses reflect current information.
There are nine elements to PAS 91, four core modules, four optional modules and project-specific questions. Optional modules and project-specific questions are included by the buyer appropriate to the project bid.
Core modules include:
Optional modules include:
- Equal opportunity and diversity.
- Environmental management.
- Quality management.
- Building Information Modelling.
PAS 91 heavily favours certification to ISO 9001 (Quality Management), ISO 14001 (Environmental Management) and PAS 1192 (Building Information Management). Providing these certificates scores full marks, and offers exemption from completing a large number of questions in an attempt to describe suppliers arrangements to meet these standards.
Observers note that PAS 91 can significantly improve the contracting sector on the topics of diversity, quality management, environmental management and now, Building Information Modelling, but requires a collaborative approach from construction clients and buyers to use and promote use for successful and meaningful uptake.
PAS 91, is currently being revised, in particular to reflect the changes in roles introduced by CDM 2015.
NB In December 2013, Enterprise Minister Matthew Hancock set out how a range of measures intended to make it easier for small businesses to grow in Small Business: GREAT Ambition. Measures were announced to tackle late payment and to remove the barriers to public contracts by abolishing pre-qualification questionnaires (PQQs) for low-value contracts and mandating the use of core PQQs for high-value contracts.
