Quality

Canary Wharf Group

Alongside Health and Safety and Environment, Quality is of critical importance to Crossrail. Every instance of poor quality compromises safety, takes time and effort to resolve, increases cost and distracts attention from driving the programme forward.

The Crossrail Management System (CMS), accredited to ISO9001: 2008, provides the framework for the planning, design, procurement, construction, installation, commissioning and bringing into service of Crossrail. The Quality Policy sets out Crossrail’s approach to quality, which is implemented through the CMS:

  • Apply the principles of ‘right first time’ and continual improvement to our performance;
  • Ensure compliance with legislation, regulatory requirements, and relevant codes of practice and standards;
  • Place accountability for quality with those best placed to act;
  • Set realistic, measurable objectives and targets for all activities, to assist delivery of performance and progress; and
  • Implement review, surveillance and audit programmes to monitor compliance with requirements and assess the effectiveness of the arrangements.

Crossrail roll these requirements down to the supply chain through the following requirements which are embedded into the Works Information Vol 2B – Section 20 -Quality Management:

All contractors are required to:

  • Have a Quality Management System (QMS), which meets the requirements of ISO 9001 and is certified by a UKAS accredited certification body (or equivalent);
  • Provide a Quality Plan which is compliant with the quality arrangements in the contract;
  • Appoint a quality manager, who is a chartered quality professional (or equivalent) and will act as the principal point of contact for quality Management issues.
  • Develop and implement ‘Inspection & Test Plans’ that when implemented provide evidence that the specified requirements have been met;
  • Develop and conduct a programme of internal audits appropriate for the works;
  • Ensure that all sub-contractors comply with the contractual quality requirements that are relevant to their scope of works;

The requirements in the Works Information are over and above the industry norm and are intended to ensure that contractors are resourced correctly and have established systems to deliver quality.  A learning legacy paper on Supply Chain Quality Requirements reviews the quality resources and systems used in Crossrail, the supply chain requirements within the Works Information, management of quality during construction, the self-certification process implemented and the quality culture across the programme.

One of the early concerns faced by Crossrail was the lack of skilled quality professionals in the construction industry.  Hence the Crossrail Quality Professional training programme was developed in partnership with the CQI to address the skills gaps. A learning legacy paper on Quality Professional Resourcing and Development shares details of the training scheme, the results and lessons learned for use by future projects.  A one day training course was also developed on non-conformance reporting and root cause analysis. Details of this ‘Spot-On’ training can be found here.

Crossrail’s approach to ‘getting the quality right’ was in the use of Inspection and Test Plans (ITPs) and self certification.  All contractors, sub-contractors and suppliers were required to produce and maintain ITPs signed off by the Crossrail NEC Supervisor. A learning legacy paper on Inspection and Testing and Self Certification, to be published in September 2017, will explain  the framework for the production, implementation, monitoring and resulting production of certification.

The Quality dashboard is how Crossrail reports quality performance across the programme. Crossrail is the first construction project to implement a Quality Performance Indicator (QPI) similar to the Health and Safety Performance Indicator.  The QPI is based on 6 existing leading and lagging KPIs:

  • work commencing without ITP
  • % Crossrail satisfactory observations
  • % Non Conformance Reports (NCRs) raised by contractors
  • %NCRs overdue
  • % certification completed on time
  • Corrective Action Reviews closed on time.

The QPI is published each period in a league table format for each Tier 1 contractor and is intended to provide visibility of performance to incentivise the programme the supply chain to improve through competition across which is an approach that has generally been successful as part of the performance assurance framework. A future learning legacy paper on the QPI will be published reviewing all the data and impact on performance of publishing a QPI.

Crossrail has captured the cost of rework of each non conformity by estimating the cost to rectify defective work against the total cost of work completed across the programme and per contract. A future learning legacy paper – Analysis of the cost of rework – will review the overall cost and the importance of providing visibility of this cost on the programme. Crossrail also regularly undertakes trend analysis to identify improvement initiatives. A learning legacy paper – Trend Analysis of Defects – will undertake a detailed trend analysis of all NCRs for use by future projects to help improvement initiatives to be undertaken to help prevent the same issues happening again. Crossrail communicates quality trends and improvement initiatives using Quality Alerts which are shared on the learning legacy website for use by other projects.

Crossrail also runs a Quality Week which is a means of engaging with the supply chain on quality matters.  Quality Week collateral will be shared on the learning legacy website for use by other projects.
