Outsourced estimating support that gives your estimator cleaner inputs.
Construction estimating services from CVA put a trained remote estimating assistant alongside the person who owns scope, quantities, pricing, and risk. The desk controls plan sets, prepares quantity takeoffs to your documented method, tracks subcontractor bid coverage, assembles the estimate record, and surfaces missing decisions before the deadline. Your qualified estimator reviews everything and owns the number that goes out.
THE OPERATING HANDOFF
Define the source, recurring work, and approval boundary.
A reliable service lane starts with controlled inputs and a named client reviewer—not a broad list of tasks with unclear authority.
INPUTS
What the desk needs
Current drawings, specifications, addenda, and bid instructions
Approved scope divisions, cost codes, and estimate template
Client takeoff standards and measurement rules
Vendor and subcontractor lists
Named estimator, review cutoff, and escalation rules
RECURRING WORK
What the desk maintains
Plan-set and addendum control
Takeoff workspace preparation and naming
Quantity takeoff support under client-defined methods
Subcontractor and supplier quote tracking
Scope-gap and missing-information log maintenance
Estimate and proposal assembly support
CLIENT CONTROL
What stays with your team
Approve takeoff methodology and scope assumptions
Validate quantities and production factors
Set labor, material, equipment, overhead, and margin
Approve exclusions, qualifications, price, and submission
VISIBLE OUTPUTS
Review the exceptions, not another activity list.
The exact format is agreed during onboarding. These are the operating records the service is designed to keep current.
RECURRING OUTPUTS
Controlled current bid set
Takeoff package ready for estimator review
Quote coverage and follow-up register
Missing-scope and decision list
Submission checklist and archived estimate record
REVIEW RHYTHM
Daily deadline and addendum check
Scheduled quote-coverage review
Estimator review before estimate lock
Post-submission file and handoff check
IMPLEMENTATION SEQUENCE
Install one bounded workflow before expanding the scope.
01
Control the source set
Name the current drawings, specifications, addenda, folder structure, and update cutoff.
02
Define the estimate handoff
Document what the support desk prepares, what the estimator checks, and what blocks release.
03
Run one live estimate
Test the workflow on one opportunity before expanding tools, scopes, or volume.
04
Review the exceptions
Use missing information, rework, and late decisions to improve the next bid cycle.
GOOD FIT WHEN
The workflow has an owner and a review point.
The estimate process has a named reviewer
Templates and cost structure are defined
The work repeats across active bids
The estimator will review before release
NOT THE RIGHT FIT
Authority or source information is missing.
No one is authorized to validate quantities or price
The scope requires unverified engineering judgment
Source drawings are uncontrolled
The request is simply to submit more bids without a review gate
COMMON QUESTIONS
What contractors ask before delegating this lane.
Answers describe how the service is scoped and where authority stays with your team.
What does a construction estimating virtual assistant do?
An estimating support desk controls plan sets and addenda, prepares takeoff workspaces, performs quantity takeoff under your documented methods, tracks subcontractor and supplier quote coverage, maintains a scope-gap log, and assembles the estimate record for submission. Your qualified estimator retains quantities, production assumptions, pricing, exclusions, risk, and final approval.
Can a virtual assistant do quantity takeoffs?
Yes, under a documented methodology you approve and subject to estimator review. The desk measures to your defined rules, scope divisions, and cost codes, and flags anything ambiguous rather than assuming. Takeoff output is prepared for review, not treated as a final quantity, because responsibility for quantities stays with your estimator.
Which estimating software do you work in?
Commonly On-Screen Takeoff, PlanSwift, Bluebeam Revu, and the takeoff and estimating modules inside the platform you already run. The desk works in your licences and your file structure rather than importing project data into unfamiliar tooling.
How is estimating support different from bid management?
Estimating support prepares one number on one job: plan control, takeoff, quote coverage, and estimate assembly. Bid management runs pursuit logistics across many opportunities: the bid calendar, go/no-go records, prequalification, and submission compliance. High-volume bidders usually need both.
Will the desk contact our subcontractors?
Yes, for quote solicitation and follow-up under an agreed communication standard using your approved vendor list. The desk chases coverage and records responses. Scope negotiation, commercial terms, and any commitment to a trade partner remain with your team.
How do you handle addenda during a live bid?
Addendum control is a core recurring task: each addendum is logged, applied to the controlled current set, checked against issued quotes, and flagged where it changes scope already priced. The point is that your estimator is never working from a superseded set without knowing it.
