Construction & engineering Construction & engineering # 4 Proposal and bid software for construction and engineering firms AEC firms win work on qualifications and project history as much as on price. The tools that fit help assemble statements of qualifications, project sheets and resumes quickly, and keep long multi-author tender documents under control. 4 tools with evidence of fitListed A to ZNo paid placement Profiles checked through Oct 2026 ## At a glance Starting prices and security listings come from each vendor profile, where every fact links to the page it was read from. “Not listed” means we could not find it published, not that the vendor lacks it. __Prices and certifications move.

A statement of qualifications, a prequalification questionnaire or, for US federal architect-engineer work, an SF 330 asks for relevant projects, key staff and their resumes. The work is finding the right projects and tailoring them, a content-reuse problem before it is a writing problem. Tenders for larger projects bring big document sets: method statements, health and safety plans, programme narratives and pricing schedules, written by several people at once. Version control falls apart quickly over email, so co-authoring and permissions can matter more than AI drafting. Go/no-go decisions carry real cost. Pursuing a public tender ties up estimators and engineers for weeks, so tools that read tender documents and summarize the requirements early can save more time than any drafting feature. ## Tools that fit, and why Each tool is listed because its published profile shows evidence of fit, quoted below. Open the profile for pricing detail, security sources and the full list of limitations. QO![QorusDocs logo](https://www.google.com/s2/favicons?domain=qorusdocs.com&sz=128) ### [QorusDocs](/qorusdocs) **Why it fits:** Sells to AEC teams and names WSP, an engineering firm, among its customers. Its strength is pitch decks and narrative proposals built in Word and PowerPoint. Profile summary: AEC **Check before buying:** Windows 10 or later plus desktop Microsoft 365 Office apps are required for end users. [QorusDocs review](/qorusdocs)[QorusDocs alternatives](/alternatives/qorusdocs) RF![RFP Response Builder logo](https://www.google.com/s2/favicons?domain=rfpresponsebuilder.com&sz=128) ### [RFP Response Builder](/rfp-response-builder) **Why it fits:** Names construction among the small and mid-size teams it serves, working inside Word and Excel with a cloud-synced content library. Who it is for: construction **Check before buying:** No generative AI drafting: answers come from the library, so it trails the AI-native tools it competes with. [RFP Response Builder review](/rfp-response-builder)[RFP Response Builder alternatives](/alternatives/rfp-response-builder) TE![Tendrio logo](https://www.google.com/s2/favicons?domain=tendrio.ai&sz=128) ### [Tendrio](/tendrio) **Why it fits:** Aimed at engineering and industrial bid teams deciding which tenders to chase, with a requirement compliance matrix built from the tender documents. Who it is for: Engineering, technology, manufacturing **Check before buying:** It analyzes and qualifies tenders; it is not a response-writing engine and has no answer library or approval workflow. [Tendrio review](/tendrio)[Tendrio alternatives](/alternatives/tendrio) XA![Xait logo](https://www.google.com/s2/favicons?domain=xait.com&sz=128) ### [Xait](/xait) **Why it fits:** Names Colas, a transport-infrastructure construction group, among its customers, and handles the long multi-author tender documents where version control usually falls apart. Named customers: Colas **Check before buying:** Questionnaire work (RFI, DDQ, security) lives in a separate product, XaitRFI. [Xait review](/xait)[Xait alternatives](/alternatives/xait) ## How to choose bid software for an AEC firm - **Project and resume reuse:** Find five relevant projects and three resumes for a new pursuit in minutes, then tailor them without editing the master copy. - **Multi-author control:** Large tenders need simultaneous editing with permissions per section and automatic formatting. - **Tender triage:** Reading tender documents into a requirement list early makes the go/no-go call cheaper. - **Output in your format:** Check that Word and PowerPoint output matches your templates, since AEC submissions are judged on presentation too. - **Price per pursuit:** Model cost against the pursuits you run a year and the engineers who contribute occasionally. ## What this list does not prove A listing here reflects the vendor’s positioning or named customers. It does not confirm support for SF 330 layouts, a specific prequalification portal or your design templates. Rebuild a recent qualifications submission in the tool before you buy. We list a tool only when its published profile supports the fit, and we publish a page only once at least three tools qualify.

QorusDocs sells to AEC teams and names WSP among its customers. Xait handles large co-authored tenders, Tendrio reads tender documents into a compliance matrix, and RFP Response Builder covers smaller teams working in Office. Match the tool to whether you need pitch decks, tender authoring or triage. What is an SF 330? Standard Form 330 is the architect-engineer qualifications form US federal agencies use to shortlist A-E firms. It asks for key personnel, their resumes and example projects, so it rewards a well-kept project and resume library. Can AI help with construction bids? It helps most with reading tender documents, summarizing requirements and drafting first versions of method statements. Pricing, programme and safety commitments still need the estimator and project lead to write or approve them. Do construction firms need proposal software or a CRM? Frequently both. A CRM tracks pursuits and relationships, and proposal software builds the submission. Many firms start with a proposal tool that works inside Word and add the rest later. How should an AEC firm trial proposal software? Rebuild a recent qualifications submission. Time how long it takes to find relevant projects and resumes, tailor them to the new client and export in the required layout.
