Tool 06 · RFP builder
Engineering vendor RFP and MSA contract redline scope builder
Choose the contract type, spend tier and the problem you most need fixed. The builder returns eight redlines to put in front of the vendor, the benchmark price floor, and an RFP scope brief you can copy into an email.
01How to use the brief
- Send the scope brief to two or three vendors at the same time, with the same deadline.
- Ask each to answer every numbered requirement in writing; a requirement left blank is a no.
- Score answers on price, the redlines accepted, and references for a comparable scope.
- Put the accepted redlines into the contract itself, not a side letter or the statement of work.
The spend tier sets the process: under $100K two quotes and standard terms are enough; above $2.5M you want a formal RFP with scoring, legal review and an executive sponsor, starting at least 120 days before renewal.
| Category | Benchmark floor |
|---|---|
| CAD/PLM VAR renewal | ≤3%/yr cap; SOLIDWORKS Pro $3,456-$4,152/seat |
| Staffing MSA | Markup ≤45%; $0 conversion after 520-1,040 hrs |
| Offshore CAD/BIM SLA | 2D $12-$18/hr; 3D/FEA $20-$32/hr; FTE $1,950-$3,600/mo |
| Turnkey NPD | $135-$225/hr; fixed EVT/DVT/PVT milestones |
| PE stamping retainer | Solar $195-$350/site; MEP MAX($2,200, sq ft × $0.55) |
02Clauses that recur across categories
Three clauses show up in almost every engineering contract we review, whatever the category:
- IP assignment in the present tense. "Hereby assigns" transfers rights as work is created; "agrees to assign" only promises a future transfer. Each individual, not only the vendor entity, should be bound.
- Price change mechanics. A cap, the index it follows, and when it can apply.
- Exit. Return of native files, deletion certificates, and transition help at agreed rates.

Questions buyers ask
What should an engineering staffing MSA include?
Disclosed pay and bill rates with a markup cap, a conversion fee that steps down to zero by 520-1,040 billed hours, a direct-hire fee ceiling, overtime billed on base pay, IP assignment from each worker and a right to audit timesheets and MSP fees.
How many vendors should an engineering RFP go to?
Two or three qualified vendors is usually enough to set a market price without overloading evaluation. Send the same scope and deadline to each.
When should we start a CAD VAR renewal RFP?
Sixty to 120 days before the renewal date, longer for estates over $2.5M a year. That leaves time to collect usage data, compare quotes and negotiate a price cap.
What is the difference between "hereby assigns" and "agrees to assign"?
"Hereby assigns" transfers intellectual property rights as the work is created. "Agrees to assign" is only a promise to transfer later, which can leave ownership disputed if the relationship ends badly.
