What sets Harrington O'Sullivan apart:
Commercial Discipline That Protects Delivery
Procurement and contracts are where projects either hold together or fall apart. These are the commercial capabilities we embed across every engagement.
EPC Contract Strategy and Structuring
EPC, EPCM, or hybrid structures selected and negotiated based on what actually protects your position. Contracts matched to your project's scale and risk profile, not to convenience.
Mining Procurement That Accounts for Reality
Long lead items, constrained supply chains, logistics to site, and vendor qualification. Mining procurement embedded in the delivery programme, not run from a spreadsheet.
Cost Control Embedded From Day One
Budget protection that starts at scope definition, not at the first cost report. Estimates benchmarked, contingencies tested, and spend tracked against baseline.
Contract Administration and Claims Defence
Variations, extensions of time, and contractor claims assessed against the contract with the rigour they require. Commercial administration that protects your interests through construction.

FAQ
Frequently Asked Questions
Common questions about our commercial, contracts, and procurement services.
What is an EPC contract and when is it the right model?
An engineering, procurement, and construction contract places design, sourcing, and build responsibility under a single contractor. It suits projects where the owner wants fixed-price certainty and single-point accountability. We advise on whether an EPC contract, EPCM model, or hybrid structure is the right fit for your project based on risk, scale, and delivery requirements.
How do you handle mining procurement for remote projects?
We build procurement strategy around the realities of the site. Long lead items are identified early, supply chain constraints are mapped, and logistics to site are factored into the programme. Mining procurement in remote environments cannot be run the same way as a metropolitan project. We plan for the conditions, not around them.
When should commercial and contracts be engaged on a project?
As early as possible. The decisions that determine whether a project stays on budget are made during scope definition and contract structuring, not during construction. We embed commercial discipline from the start so procurement strategy, contract terms, and cost baselines are established before commitments are made.
Do you manage contractor claims and variations?
Yes. We assess every claim against the contract, evaluate variations for cost and programme impact, and manage extensions of time with the rigour required to protect your position. Commercial administration is not paperwork. It is budget defence.
Can you review or restructure existing contracts on a project already underway?
Yes. We can audit existing engineering, procurement, and construction contracts, identify commercial risk, and restructure where necessary. Whether the issue is cost exposure, unclear scope boundaries, or contractor performance, we assess the position and act on it.
