Project Bid Submission
Why Construction teams use Kerna
Project bid submissions take hours to draft — getting the tone right matters for winning
Multilingual job sites generate correspondence in multiple languages from subcontractors
Change order notifications need careful phrasing — they have real cost and liability implications
Progress updates to clients are repetitive but critical for transparency
RFI responses get delayed during site work — slowing entire project timelines
Safety meeting reminders and permit notifications feel templated and get ignored
Built around how Construction teams actually work.
Formal tone for bids and contracts
Bid submissions and subcontractor agreements need formal, precise language. Kerna handles the boilerplate so you can focus on numbers.
Multilingual subcontractor coordination
Coordinate with subcontractors in their working language — Polish crews, Portuguese suppliers, Spanish electricians. Communication friction drops.
Direct tone for change orders and RFIs
Change orders need precise, unambiguous language. Direct tone delivers facts without padding — critical when documentation matters.
Custom Templates for standard procedures
Save your firm's standard responses for permit notifications, safety reminders, warranty information. Consistency across projects.
Your Construction inbox, sorted the way you sort it
Kerna starts you with five categories built for this industry and hands them to you in your own language. Rename them, rewrite them, or add one of your own. Nothing is fixed and nothing is saved until you say so.

Frequently asked questions
Does Kerna integrate with our PM software (Procore, BuilderTrend)?
Kerna lives in Gmail. Project details from your PM software can be pasted into the compose flow; Kerna handles the writing. No direct integration with construction PM tools is required.
How does it handle technical construction terminology?
The underlying language model understands standard construction vocabulary. For specialised terms (specific code references, local building standards), Custom Templates let you lock in exact phrasing.
Can field staff use it on mobile?
Yes. Kerna works inside the Gmail mobile app — useful for project managers running between sites who need to send updates from the field.
Is it useful for solo contractors or only larger firms?
Both. Solo contractors get the most leverage from the proposal and invoice features. Larger firms use it for team coordination — Business plan supports shared templates across PMs and field staff.
