Detailed calculations, coordination with the architect and other trades, and a design-development set for the Client's review.
PHASE 3 · CONSTRUCTION DOCUMENTS
Stamped and signed construction documents, coordination with permit authorities, and responses to plan-check comments.
Not included: on-site inspections, shop drawing review, expert testimony, and design changes after documents are stamped. New scope can be added in writing at any time.

The Engineering Contract template is a five-page document for putting an engagement between the Engineer and the Client on paper before work begins. It carries an overview with stat cards, a three-phase scope of work, a fee table with a computed total and payment schedule, and an acceptance page with inputs and signatures.
It is intentionally simple: rename what needs renaming in Bonsai, edit the scope and fees to match your engagement, and send. Merge fields handle the party details and date, and the last page collects the fields you need plus both signatures.
Everything below comes pre-configured. Turn sections on or off, edit the copy, or add your own — Bonsai remembers your choices for next time.
Are on-site inspections included? No — site inspections during construction are billed hourly or under a separate construction-administration agreement.
Who owns the drawings? The Engineer retains the copyright; the Client receives a license to use the drawings for the specific project once fees are paid.
What if the design changes mid-project? Changes are handled by written change order at the Engineer's standard rate and may extend the schedule.
