Fixed-price contracts or time-and-material — your call.
DSI works with GCs, owners, and project managers to structure billing in whatever format fits your project and accounting requirements — fixed-price lump sum or time-and-material.
Fixed-price contracts give you certainty for budgeting. T&M hourly is right for projects with undefined scope, change-order-heavy environments, or when you need to put boots on the ground fast without waiting for a formal estimate.
A lump sum contract sets one price for a defined scope. It gives owners and GCs budget certainty and puts the production risk on the subcontractor. It works best when the drawings, quantities, access and schedule are clear enough to price accurately.
A time and material contract bills the actual labor hours, equipment time and materials at agreed rates. It is the right fit when the scope can't be fully defined in advance, when work is driven by changes in the field, or when you need a crew on site quickly without waiting for a formal estimate.
Some scopes are priced per unit: per core hole by diameter and depth, per linear foot of saw cut, per load hauled. Unit prices suit work where the type of work is known but the final quantity isn't, such as core drilling hole schedules that keep growing.
We will recommend a structure when we review your scope, and we can price it more than one way.
