How much will it cost?

Fee estimates

I provide a project-specific fee estimate for every enquiry based on the size and complexity of the project, the procurement route, and the programme.

I generally recommend working on an hourly rate, up to an agreed (not to be exceeded without authority) target fee. I can also base fee estimates on a rate per work section, a percentage of the total estimated construction cost, or a lump sum, if these are appropriate alternatives to an hourly rate.

I also offer a pre-written, non-project-specific, "Basic Specification" suitable for Small projects.

How many hours?

The time taken to write a full NBS format contract specification depends primarily on the complexity of the project, and not on its size and/ or construction value. For initial fee estimates I work to the following:

  • Typical non-residential building projects up to 20m construction cost. Between 75 and 100 hours, based on 30 to 35 architectural work sections, taking an average of 2.5 to 3.0 hours each to write.
  • Typical residential projects up to 20m construction cost. Between 75 and 100 hours, based on 35 to 40 architectural work sections, taking an average of 2.0 to 2.5 hours each to write.
  • Simple residential projects up to 20m construction cost. Between 50 and 75 hours, based on 35 to 40 architectural work sections, taking an average of 1.5 to 2.0 hours each to write.
  • Typical building projects over 20m construction cost, and complex building projects up to 20m construction cost. Between 100 and 250 hours, based on complexity.
  • Typical interior design projects. Between 50 and 75 hours, based on 25 to 30 work sections, taking an average of 2.0 to 2.5 hours each to write.

The estimates above exclude the Contract Preliminaries, and those work sections normally specified by the structural engineer, services engineer, and landscape architect. These can generally be included at an additional cost.

What about the Contract Preliminaries?

I am always happy to provide an estimate for writing the Contract Preliminaries in addition to the Work Sections.

... and partial services?

I am always happy to provide an estimate for partial services, even down to writing a single Work Section if necessary. Partial services can be very useful for project teams, already using NBS Building, who are working to tight deadlines.

... and Employer's Requirements?

For specifications suitable for incorporation into Employer's Requirements documentation, e.g. for Design-and-Build and PFI-type contracts, the fee will be around 75% of the cost of the full contract specification as set out in the examples above.

If the project is well-defined at the Employer's Requirements stage, with the expectation that the architect preparing the Employer's Requirements will be novated to the successful tendering contractor, then the fee for preparing an Employer's Requirements specification will generally be the same as for a full NBS format contract specification. It will then be sensible to allow an additional 25% for the work required to accommodate changes requested by the successful Contractor post-novation.

What else detemines the fee?

Fees will generally be lower if:

  • The project is straightforward in procurement route, construction method, and products selected.
  • I can be provided with a substantially-complete set of construction drawings, both General Arrangement Drawings and Details, before starting work.
  • Most communication will be by email and visits to your office can be kept to a minimum.

Fees will generally be higher if:

  • The project is complex in procurement route, construction method, or products selected.
  • I am required to produce the specification concurrently with you producing the construction drawings.
  • Regular visits to your office are required.
