What it means
The contractor agrees to complete the work shown in the drawings and specifications for the stated price. If actual costs end up higher, the contractor bears the difference, unless the owner changes the scope.
This type of contract usually relies on complete, coordinated documents.
Why it matters
Owners like stipulated sum contracts because the price is known up front. The trade-off is that the scope must be tightly defined, and any change after signing is priced through a change order. Incomplete drawings lead to disputes over what was included.
Fixed price also means the contractor may be cautious in how it prices unknown conditions, so strong documents help keep the number fair.
How HSM handles it
When a project suits a fixed price, HSM prices it from complete information and states clearly what is included and excluded. We review the site and the existing systems before pricing so that hidden conditions are accounted for as much as possible.
Our own electrical, mechanical, interior systems and carpentry crews allow us to price these large parts of the work directly from our experience, not from layered subcontract quotes. That tends to produce a more accurate number.
If the design is still developing, we may recommend a different structure and explain why.
What to plan for
A fixed price is only as firm as the drawings behind it. If you expect the design to change, say so, so we can choose a structure that does not turn every revision into a dispute.
