Interior fit-out

Quantity surveying and claims support for interior fit-out, including partitions, finishes, fittings and building services.

Commercial challenges and how we approach them

Fit-out turns a shell or existing space into usable premises. The scope can include strip-out, partitions, ceilings, joinery, finishes and changes to services. Landlord provisions, the fit-out contractor’s work and items supplied by the occupier need to meet without gaps, particularly where design and procurement continue during a short delivery period.

Jack Butler-Kettle’s career includes a quantity surveying role with Overbury. This is personal career experience before Quantsurv.

Landlord provisions and tenant requirements

The Challenge

A tenant fit-out can be priced on the assumption that the landlord's power, cooling and fire systems are ready to use. If the base build is incomplete or those systems cannot meet the agreed requirements, the fit-out team may inherit work it has not priced.

Our approach

We compare landlord information, surveys and fit-out inclusions. The resulting scope record separates tenant changes from missing base-build provision and provides a basis for assessing additional work.

Design decisions during a short programme

The Challenge

A late joinery or layout decision can cost more in rework than in replacement materials.

Our approach

We link each decision to the purchase orders and work already installed. Unordered items, cancellable orders and completed installations need different treatment. The valuation includes substantiated alterations and consequential work, with credits for the original scope, so the client can see the cost of the decision before commitment where practicable.

Existing services that cannot simply be reused

The Challenge

A retained installation may lack capacity, records or compatible controls. Discoveries during strip-out and testing can change the extent of replacement and leave the original reuse allowance disputed.

Our approach

We check the priced reuse assumptions against the technical findings. Testing, replacement and omitted refurbishment are valued separately, so the contractor is not paid both to retain an installation and to replace it.

Logistics inside an occupied building

The Challenge

An occupied office tower may offer only booked lift slots, limited loading-bay access and short noisy-work periods. If floors are released differently from the tender sequence, trades can spend more time moving, protecting and setting up than the measured quantity suggests. A square-metre rate alone will not explain that claim.

Our approach

We compare the priced logistics with delivery, shift and area-release records. The assessment identifies the additional handling or attendance caused by the change, separately from normal fit-out obligations.
