From the first study to deliveryExecution stages

Five stages run by the same structure, with single-point accountability from start to finish.

Constructability, scope definition, strategy, estimates and risks.

Design coordination, execution planning, budgeting and value engineering.

Bidding, qualification, negotiation, contracting and supply chain management.

Mobilization, execution and integrated management of safety, quality, schedule and cost.

Testing, commissioning, documentation, transition and post-construction follow-up.

Which model makes senseWhen to hire COSTAL

Three common situations and the contract format that usually works best for each.

You already have the design and want a fixed price.

We take the construction documents, price them and deliver the project for a set amount. You know the cost before you start, and the risk of overruns stays with us.

Best whenThe scope is mature, the design won't change midway and cost predictability matters more than flexibility.

How it's contracted: General Contractor, with a lump-sum price.

You have the need, but the design doesn't exist yet.

We take on design and construction under one contract. We develop the solution within the budget you set, instead of designing first and finding out the cost later.

Best whenYou have the site, the deadline and the investment ceiling, and you want a single party responsible from design to handover.

How it's contracted: Design & Build or EPC, with a guaranteed maximum price.

You want visibility into every project cost.

You see the purchase invoices, the supplier quotes and our fee separated from the cost. Savings from negotiation go back into your investment.

Best whenThe scope will still evolve during construction, or your governance requires every expense to be traceable.

How it's contracted: Open book or cost-plus, under Construction Management.

What each term means

General Contractor: COSTAL takes on the entire project and answers to you for schedule, cost and quality.
Construction Management: COSTAL manages the project and the contracts, which remain in the client's name.
Design & Build: Design and construction in a single contract, with the budget set before the design.
EPC / EPCM: Engineering, procurement and construction in one package. In EPCM, we manage and you contract.
Lump sum: A fixed amount for the contracted scope. The risk of overruns sits with the contractor.
Cost-plus: You pay the actual project cost plus an agreed management fee.
Open book: All costs are open for audit, with the contractor's fee kept separate.
GMP: Guaranteed maximum price: there is a ceiling, and savings below it are shared or returned.
CAPEX / OPEX: The project is booked either as an investment in the asset or as a recurring operating expense.
Hybrid contracts: A combination of the formats above by stage or by work package.
