Do engineers offer fixed-fee proposals?
Yes — for permit-driven design work, a fixed fee is the normal way commercial engineering is bought, and you should expect one whenever the scope can be defined. Fixed fee works when the deliverable is concrete: a drawing set, a calculation package, a sealed submittal for a named building in a named jurisdiction. Where the scope genuinely cannot be bounded in advance — evaluations, forensic work, repair design on a building nobody has opened up — engineers quote hourly or phased fees instead, and an honest engineer will tell you which situation you are in.

When a fixed fee is realistic
A fixed fee is realistic when three things are known: the building, the scope list, and the jurisdiction. The building means type, size, and structural and MEP systems. The scope list means the named deliverables — which drawings, which calculations, which compliance documentation. The jurisdiction means the building department whose checklist the set must satisfy, because that checklist decides how much proof the set carries. With those three fixed, an experienced firm can price the hours with confidence. Without them, a fixed number is either padded or fragile, and both versions cost the owner money later.
What a good fixed-fee proposal names
Read a fixed-fee proposal for its nouns. It should name the deliverables sheet by sheet or system by system, state what is excluded as plainly as what is included, say how many rounds of plan-check correction responses the fee carries, and define how revisions after issuance are billed. It should also name the assumptions the price rests on — the state of the architectural set, the equipment selections, the soils report — so that when an assumption changes, everyone already knows it is a scope change rather than an argument. Vague proposals produce precise invoices; precise proposals produce predictable ones.
When hourly or phased pricing is the honest answer
Some work cannot be fixed-fee honestly. A structural evaluation of an existing building depends on what the inspection finds. Forensic work follows the evidence. Repair design depends on the extent of damage behind finishes nobody has removed. For these, expect an hourly rate with a cap, or a phased structure: a fixed fee for the assessment phase, then a fixed fee for the design phase once the assessment defines it. Phasing is the pattern to ask for — it converts an unbounded scope into a sequence of bounded ones, each priced with the information the last phase produced.
How Torch prices
Torch quotes qualifying scopes as a fixed fee the same day the drawings arrive: a complete set, a clear jurisdiction, a defined deliverable. The proposal names the deliverables, the correction rounds included, and the assumptions underneath the number. Scopes that are not ready to fix — unstable design, unknown existing conditions — get a phased structure or a firm timeline for when they can be priced, stated in the first reply rather than silence. One contact owns the job from quote to delivery, so the person who priced your scope is accountable for delivering it.
The bottom line
Fixed fees are standard when the building, the deliverable list, and the jurisdiction are known. Judge a proposal by what it names — deliverables, exclusions, correction rounds, and assumptions.
