Construction Works and Associated Services 3

The Construction Works and Associated Services 3 (CWAS3) framework (RM6320), managed by Crown Commercial Service (CCS), is a major public sector procurement framework designed to provide compliant delivery of construction works and associated services across the UK.
CWAS3 replaces previous iterations and builds on the success of earlier frameworks, offering a structured and accessible route for public sector organisations to procure construction services at scale.
Key Framework Details:
Framework ID: RM6320
- Authority: Crown Commercial Service (CCS)
- Scope: Construction works and Associated services
- Target Users: Central government departments, local authorities, NHS bodies, education providers, and wider public sector organisations
- Bid window: 8 weeks
- Estimated Value: £144 billion (total)
- Structure: Multi-lot (up to 4) framework covering varying project sizes, scopes, and regional delivery
What Does CWAS3 Cover?
The framework is designed to support a wide range of construction-related requirements, including:
- General construction works (new build and refurbishment)
- Mechanical & Electrical (M&E) services
- Civil engineering projects
- Design and build services
- Minor works and major projects
- Associated professional and support services
CWAS3 also incorporates ProCure24 (P24), which specifically supports NHS capital projects, making this framework particularly competitive and technically demanding.
What Buyers Are Looking For...
Suppliers bidding for CWAS3 must demonstrate:
- Strong technical delivery capability
- Health & safety systems
- Proven project management methodologies
- Clear mobilisation and resourcing plans
- Effective risk and quality management processes
- Commitment to social value and sustainability
- Experience delivering public sector projects
This is not a tick-box exercise - evaluators expect clear, evidenced and practical responses that demonstrate how you will deliver projects, not just that you can.
Why Do You Need Specialist Support for CWAS3?
CWAS3 will attract highly capable contractors with strong technical experience.
This means:
- Compliance alone is not enough
- Responses must be clear, detailed, and evidence-driven
- Evaluators must quickly understand your delivery model and strengths
This is a complex, high-pressure framework offering high-value rewards. Not only does our bid team have experience winning similar frameworks within this sector, but each writer also understands:
- The pressure on internal teams during live tenders
- How to extract information from technical staff
- How to turn complex delivery processes into clear, persuasive responses
- What buyers are looking for and how to tailor responses accordingly
Bid Writing Service's Experience in Construction Frameworks & Public Sector Tendering
At Bid Writing Services (BWS), we specialise in supporting construction, engineering, and M&E organisations through complex public sector frameworks, just like CWAS3.
Relevant Experience
We have supported clients across:
- CCS frameworks and DPS’s
- NHS and healthcare construction frameworks (including submissions similar to ProCure)
- Local authority and housing frameworks
- Major works and capital projects
- M&E and specialist subcontractor tenders
Our involvement in these projects included but was not limited to:
- Supporting suppliers onto national and regional construction frameworks
- Writing high-scoring method statements and technical responses
- Developing compelling case studies and project evidence
- Aligning submissions with evaluation criteria and scoring matrices
- Managing full end-to-end tender submissions
How is Our Approach Different?
At BWS, we don’t produce generic bid content. Instead, our services are tailored to each client, ensuring we’re creating the content relevant to their business growth objectives and writing bids that align to both our client and the buyer’s specification.
Here are some of the things we deliver that other bid writing services don’t:
- Translating your complex technical delivery processes into clear responses aligned to scoring criteria
- Focusing on evidence-backed writing rather than unsupported, generic claims
- Ensuring full compliance with CCS requirements, including a compliance review prior to submission
- Structuring responses strategically to maximise clarity, readability, and scoring potential
- Working collaboratively with your team to extract the right level of detail and work within your schedule
For frameworks like CWAS3, this level of detail is essential. Strong suppliers often fail because they cannot clearly communicate how they deliver, not because they lack capability.
Our Specialist Writers
For suppliers preparing for the Construction Works and Associated Services 3 framework, technical understanding matters - these are not simple copywriting exercises.
Construction and M&E bids require clear evidence, practical delivery detail, strong compliance awareness and the ability to translate technical operations into responses that evaluators trust and can score highly.
This is where our Senior Bid Writer, Rhiannon White, brings direct sector experience.
Before joining BWS, Rhiannon spent three years working for an M&E engineering consultancy, where she was responsible for writing, managing and submitting all company bids.
Her role covered the full end-to-end tender process, from reviewing opportunities and deciding whether they were suitable, through to planning submissions, gathering technical input, writing method statements, coordinating evidence, completing compliance checks and managing final portal uploads.
During this time, Rhiannon wrote and won all of the consultancy’s bids, giving her first-hand experience of what it takes to compete for technical construction and building services contracts.
She understands the pressure suppliers face when pulling together tender submissions, particularly when project teams are busy delivering live works. Additionally, she offers internal technical knowledge, making it easy to translate complex delivery details into clear, structured and persuasive bid content.
Her background gives her a practical understanding of the areas that matter most in construction and M&E tendering, including:
- Project delivery methodology
- Mobilisation planning
- Health and safety management
- Quality assurance
- Risk management
- Contract management
- Resourcing and supervision
- Supply chain coordination
- Social value
- Environmental commitments
- Evidence gathering and case study development
Rhiannon’s experience means she is not approaching construction framework submissions purely from a theoretical writing background. She has worked inside a technical consultancy, managed live tenders directly and understands how construction and M&E businesses need to present themselves to public sector buyers.
Rhiannon knows that a strong bid is not just about saying that a supplier is experienced, compliant or reliable. It is about showing how that experience will be applied, how risks will be controlled, how quality will be evidenced and how the client will receive a safe, well-managed service.
What Rhiannon’s Support Looks Like
When supporting a CWAS3 or ProCure24 submission, Rhiannon’s role is to help suppliers turn their operational knowledge into clear, compliant and high-scoring bid responses.
Rhiannon begins by taking the time to understand your businesses – your service areas, project history, workforce, accreditations, management structure, supply chain, systems, policies and previous contract outcomes. This allows the bid to reflect how your business works, rather than relying on broad claims that could apply to any contractor.
Rhiannon will complete a thorough compliance check before starting any planning. Following this, she will complete a gap analysis to identify where evidence needs to be expanded/created and will work with any previous bid content you have to make her responses as tailored as possible. Beyond general writing services, Rhiannon can also support with case studies, CVs, policies, compliance documents and final quality checks to make sure the submission is complete, consistent and easy for evaluators to follow.
Because Rhiannon has managed bids from the supplier side, she understands the importance of making the process feel manageable. Construction and M&E tenders often involve multiple contributors, including directors, estimators, project managers, health and safety leads, quality managers and finance teams.
Rhiannon is experienced in drawing information out of technical staff, identifying where evidence is missing and shaping that information into responses that are clear, detailed and aligned with what the buyer is asking for.
