OP Contract

Commercial support that understands steelwork

Drawing revisions, programme changes, restricted access and additional site requirements can affect the cost of a steelwork package. Managing those changes means understanding both the work involved and the contract behind it.

OP Contract brings together practical experience in fabrication and estimating, specialist steelwork quantity surveying and senior contracts management.

Whether you need ongoing commercial support or help with a specific variation, claim or disputed account, John Paul Oliver works with you to establish the position and identify the next steps.

Services

Steelwork commercial support, end to end

Five areas of support for steelwork packages — from the first contract review through to final account and, where needed, disputed accounts.

01

Steelwork quantity surveying

Commercial support for structural steelwork packages, from initial review through to final account.

Support includes

  • Applications for payment and valuations
  • Cost reporting and commercial forecasting
  • Measurement and valuation of additional work
  • Subcontractor account management
  • Final account preparation and negotiation
02

Contracts management

Understand your obligations before signing and manage them throughout delivery.

  • Clarification of scope, exclusions and responsibilities

  • Assessing the cost of additional or changed work
  • Preparing and submitting variation valuations

Support includes

  • Reviewing the contractual basis of a claim
  • Gathering and assessing supporting records
  • Preparing and valuing claims
  • Assessing claims received from other parties
  • Supporting negotiation and commercial settlement
05

Dispute management and final accounts

Practical support when valuations, variations or final accounts cannot be agreed.

Support includes

  • Reviewing disputed valuations and deductions
  • Assessing unresolved variations and claims
