Our Services

Cost Planning

Cost planning and estimating is a service provided by Glyndwr Consulting throughout the pre and post construction of a project lifecycle.

We continue to update and produce further iterations of the cost plan as we move through the RIBA Stages, to ensure it is fit for purpose and includes a suitable level of detail. The detail increases as the project proceeds:

  • RIBA Stage 1/2 – cost plan is based on £/m2 unit rates initially applied to GIFA and then elemental quantities as the design permits.
  • RIBA Stage 3/4 – cost plan is broken down into sub-elements and detailed items are quantified and unit rates applied.

The format of the cost plan will follow the industry recognized Royal Institute of Chartered Surveyors (RICS) New Rules of Measurement (NRM) format.

During all stages we feedback to the project design team on design versus budget, facilitating the design to be adapted and changed to ensure the project is delivered on budget.

Our estimating processes are applied throughout and cover:

  • Site option cost appraisals
  • Massing studies
  • Stage cost plans
  • Alternative design cost appraisals
  • Pre-tender estimates
  • Pre-costing variations
Project Benchmarking

Benchmarking is a key process we undertake to provide confidence in the figures submitted as part of the cost plan. We undertake detailed analysis of all successful market tenders received to help inform all future cost plans. Abnormal costs relating to site issues, location, planning etc are stripped out to allow the base costs to be understood and captured.



Our team have the in-depth knowledge and experience to advise our clients on the most appropriate tendering and contractual procurement options for their project.

We have experience delivering traditional and design and build projects, with negotiated, single stage and two stage procurements utilising all mainstream forms of contracts.

Where appropriate, we can advise on suitable tenderers for the building contract.

Key activities include:

  • Liaise with the client’s legal advisers and advise on use and / or amendment of standard forms of contract.
  • Advise client on suitable tenderers, reporting on their financial status and technical competence.
    Prepare the tender documents in conjunction with the professional team and deliver to the selected tenderers.
  • Detail and manage the tender process, resolving any queries raised, attending pre- and post-tender interviews.
  • Analyse tender returns and prepare a tender report with recommendation for client’s approval.
    Agree pre-construction commencement activities and draft contract documents. Arrange signature by parties.
  • Maintain and develop the cost plan and cash flow forecast.


Our post contract activities are designed to remove project surprises and proactively manage risk.

We advise on the cost of variations prior to them being issued and fully engage and contribute to early warning and risk reduction meetings. This allows fully informed decisions to be made.

We fully analyse all projects to inform future project cost plans and include results in benchmarking exercises where client permissions are given.

Key activities include:

  • Attend the site progress meeting and update on financial matters. Issue monthly financial reports to the client.
  • Visit the site as required to properly assess progress and prepare recommendations for interim payments.
  • Advise on the cost of variations prior to the issue of instructions and negotiate an actual cost with the contractor for those progressed.
  • Attend and contribute to early warning and risk reduction meetings.
  • Advise on contractual matters.
  • Prepare the final account and negotiate agreement of all parties
