Pre-Qualification Questionnaires

PAS91 Questionnaires, Known as Construction Pre-Qualification Questionnaires, Are Used to Assess Supply Chains Across a Wide Range of Areas, Including New Build, Extensions, Repairs and FM, Across a Whole Range of Market Sectors.

Assessing the Construction Supply Chain with PAS91

PAS91 pre-qualification questionnaires consist of a standardised set of questions that are used by clients to ascertain the compliance of construction supply chains before awarding work.

While PAS91 is not currently mandated by CDM regulations, CHAS does comply with the question set defined in PAS91. Clients can use CHAS to generate PAS91 questionnaires for potential contractor partners to complete.

Where pre-existing certifications are in place, PAS91 will allow clients to recognise these and cut down on additional questions. For example, if the supplier has been assessed by a member of SSIP or has ISO 9001 or 14001​ issued by an accredited certification body, by providing evidence of this, they can cut down on the number of required responses.​​

Main Areas Assessed under PAS91

Health and Safety

Health and Safety

The assessment is carried out electronically as a desktop exercise – reviewing your safety policy and associated procedures, processes, arrangements and records – so there are no visits to your office or site. On successful outcome to the assessment you gain accreditation and are licensed and entitled to use the CHAS logo on your letterhead and livery and have access to your records to see detail of any client who has been reviewing your registration.

The assessment is carried out by one of our qualified assessors, who have specialisms including designer, principal designer and care sector, so you can be assured that any assessment is being carried out by an assessor with an appropriate knowledge base. Our assessors take a pragmatic approach and will take the size and scope of your business into consideration when undertaking the assessment.​


Environmental Impact and Sustainability

Sustainability is now a key issue for many companies, and clients are keen for potential contractors to have a commitment to sustainable environmental practices.

Typically, a written policy of one to two pages that reflects your business processes will suffice when evidencing environmental management and sustainability. The kind of information requested will be:

  • A copy of an environmental management policy
  • Details of any accredited environmental management system

The environmental application will operate as follows:

If you have an ISO 14001, BS8555 or EMAS accreditation, you can supply your current certificate to CHAS to complete your environmental application with us. Alternatively, you will be required to answer a standard question set in alignment with PAS91 standards.


Quality Management

Supplying quality management certification will reassure clients that your organisation has the management systems and processes in place to consistently deliver the goods or services required in the contract.

The quality management application will operate as follows:

If you have an ISO 9001 accreditation, you can supply your current certificate to CHAS and complete your quality management application with us. Alternatively, you will be required to answer a standard question set in alignment with PAS 91 standards.


​Financial​ & Business Standing

The financial and business standing assessment ascertains whether a company is financially capable of delivering the requirements of the proposed contract. This is particularly important for buying organisations looking to tender high-value, long-term contracts — especially if there is a high potential impact should contractor failure occur.

The information typically requested is used to ascertain your cash flow, financial history and financial operating practices. This can include:​​

  • A copy of your audited accounts or similar
  • A reference from your bank
  • A copy of your insurance documents

​​We recognise that some SMEs or newly established businesses cannot always demonstrate the necessary track record demanded. Most clients will make allowances for alternative methods of showing financial standing.


Equal Oppor​tunities & Diversity

Our equal opportunities and diversity assessment provides clients with information on your equality and diversity policies and how you promote these among your workforce.

Clients will be looking for evidence that you are compliant in your processes with the Equality Act 2010 and Human Rights Act 1998. They may also consider whether you are fully committed to non-discrimination and the advancement of equal opportunity in your business processes. They may look for evidence that you foster good relations when running your business and providing a service.

The kind of information requested can include;​

  • Your Equal Opportunities and Diversity Policy
  • Details of any unlawful discrimination or breach of equality law, or any formal investigations carried out in the last three years
  • Copies of recruitment, training and promotion instructions, documents available to employees and the trade union, and recruitment advertisements or other literature that demonstrates how your policy is communicated to staff and recruits​​.

Additional Products

Anti-bribery and corruption

Anti-Bribery and Corruption

The anti-bribery and corruption (ABC) assessment provides clients with reassurance that adequate procedures are in place to prevent corrupt practices.

ABC also forms part of the United Nations Global Compact in regards to Corporate Sustainability, where it seeks to eradicate corrupt practices in all forms.

Demonstrating that you have adequate procedures in place to prevent persons associated with your organisation from receiving bribes or bribing others will help to protect you in case of potential prosecution.

Modern Slavery

Modern Slavery

The modern slavery assessment seeks to gain assurance that supply chains are implementing best practice when taking steps to prevent modern slavery and human trafficking from occurring within organisations.

During assessment, CHAS will consider which steps your organisation has taken to assess and manage modern slavery and human trafficking risks.

While there is no requirement to produce a statement (below a certain revenue threshold), best practice is for companies to seek assurance from their suppliers that these practices do not exist. Therefore, we recommend all contractors seek accreditation to protect their organisations and ensure pre-qualification success.

Building Information Modelling

Building Information Modelling (BIM)

Building information modelling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of places.

Building information models (BIMs) are files (often but not always in proprietary formats and containing proprietary data) that can be extracted, exchanged or networked to support decision-making regarding a building or other built asset. Current BIM software is used by individuals, businesses and government agencies that plan, design, construct, operate and maintain diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, bridges, ports and tunnels, etc.*
