Structural engineering is a precision discipline where a principal's time is most valuable when applied to analysis, calculation review, and client consultation. Yet according to the American Council of Engineering Companies (ACEC), principals at structural engineering firms spend an average of 20 to 30 percent of their time on proposal writing, billing administration, and internal scheduling — work that does not require a professional engineer's license.
Virtual assistants are stepping in to handle this overhead, giving structural engineering firms a leaner path to profitability.
Proposal Coordination
Winning new projects depends on submitting well-organized, timely proposals. But assembling a structural engineering proposal involves gathering resumes, compiling project experience sheets, formatting fee schedules, obtaining certificates of insurance, and coordinating with subconsultants for their scope sections. Each step takes time the principal cannot afford to lose.
A virtual assistant manages the proposal assembly process from receipt of the RFP to final submission. They create a proposal schedule, send document requests to team members, format the response according to client requirements, compile appendices, and handle electronic submission logistics. When the firm wins the project, the VA also prepares the contract execution package and tracks the signed agreement to receipt.
ACEC's 2025 benchmarking data shows that engineering firms with organized proposal processes have win rates 15 to 20 percent higher than firms that treat proposals as an ad hoc exercise.
Calculation Review Scheduling
Quality control in structural engineering requires scheduled peer reviews of calculations before deliverables are released to clients or contractors. Coordinating these reviews — identifying available reviewers, booking calendar time, distributing calculation packages, and tracking review completion — is a recurring administrative cycle.
A virtual assistant maintains the QC review calendar, sends distribution packages to reviewers on schedule, logs review completions, and follows up with reviewers who have not returned marked-up documents by the target date. This prevents calculation packages from stalling in review queues, which is one of the most common causes of structural deliverable delays on commercial and institutional projects.
Client Billing Administration
Structural engineering firms typically bill on hourly or lump-sum contracts with monthly or milestone-based invoicing. The Bureau of Labor Statistics places the median hourly wage for structural engineers at approximately $50, making every hour spent on billing administration a direct cost to the firm.
A virtual assistant handles the billing cycle end-to-end: pulling time entries from the firm's project accounting system (e.g., Ajera, Wind2, or Deltek Vision), preparing draft invoices for principal review, sending approved invoices to clients, logging payments, and following up on outstanding receivables. Monthly, the VA prepares an accounts receivable aging report so the principal can identify at-risk collections before they become write-offs.
Supporting Business Development
Beyond active projects, structural engineering firms depend on a steady pipeline of new work. A virtual assistant supports business development by maintaining the CRM database, preparing qualification packages for new client outreach, tracking conference and event registrations, and coordinating follow-up after proposals are submitted.
The Utilization Rate Connection
ACEC's financial surveys consistently show that engineering firms with higher staff utilization rates — the percentage of hours billed versus total hours worked — generate better profit margins. When principals reclaim 10 to 15 hours per week from administrative tasks and redirect those hours to billable technical work, utilization rates improve meaningfully.
