# Detect tampered and deepfake Construction Draw Request > A construction draw request is a contractor asking to be paid for work already in place, and the lender's cash follows it. That makes the schedule of values the target: percent complete gets nudged, stored materials get invented, retainage is quietly reduced. The standard AIA G702 and G703 layout is rigid and closed, so every edit has to be carried through a chain of totals, and the places where the chain was not carried through are how the document is caught. **Canonical URL:** https://tampercheck.ai/documents-support/construction_draw_request **API document class:** `construction_draw_request` --- ## What a genuine construction draw request contains The summary sheet states the original contract sum, net change orders, contract sum to date, total completed and stored, retainage, total earned less retainage, previous certificates, and current payment due. Behind it the continuation sheet lists every line of the schedule of values with its scheduled value, work completed in prior periods and this period, materials stored, percent complete, balance to finish, and retainage. The two sheets have to agree. Each line's completed total is prior work plus this period plus stored materials, percent complete is that total over the scheduled value, and the sums of the columns feed the summary. Previous certificates should equal what the last application certified. A contractor's signature with a notary acknowledgement and the architect's certified amount close the form, so both are checked for consistency with the sheet above them. ## How construction draw request forgeries are made ### Percent complete inflation Work completed this period is raised on lines that are behind, pulling cash forward. The line still foots if percent and balance are rewritten, but the summary total and the architect's certified amount then disagree. ### Phantom stored materials Materials presumed to be on site are added to a line to raise the amount due without any work in place. The lines reconcile perfectly, so the signal is the edit itself: figures typed into a finished sheet. ### Retainage reduction The retainage held back is lowered or dropped, increasing the net payment. Retainage that differs from the rate in the contract is visible against the earlier applications in the same file. ### Signature and certification transplant An architect's or notary's block from an earlier, approved application is lifted onto a new one. The transplanted region keeps the resolution and tone of its source and often sits slightly off the form's alignment. ## What TamperCheck checks on a construction draw request TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class. ### Arithmetic reconciliation Stated totals are recomputed from their components, and running or cumulative figures are checked for continuity across periods. A single edited value breaks the chain even when the page still looks right. ### Table structure integrity Inserted and deleted rows leave structural artifacts behind: inconsistent spacing, misaligned columns, and formatting the visible table no longer accounts for. ### Signature forgery analysis Signature regions are assessed for ink consistency and for how the stroke sits on the page, which distinguishes a genuine pen stroke from a pasted image of one. ### And many more checks The three above are the layers that carry the most weight on a construction draw request. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks. ## Who verifies a construction draw request, and why Construction lenders, owners, architects, and draw inspectors. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging. ## How to verify a construction draw request in 4 steps 1. **Check the fields against each other.** Read work completed this period, percent complete and balance to finish, and retainage together rather than one at a time. Forgers typically change one value and leave the rest of the document describing the original. 2. **Inspect the file metadata.** Open the document properties and look at the producer, creation date, and modification date. A document produced by a consumer PDF editor, or created long after the date printed on its face, is worth a closer look. 3. **Ask for a second document.** Request a corroborating document from the same issuer or an adjacent period. Forgery effort concentrates on one file, so inconsistencies surface as soon as there are two to compare. 4. **Run a forensic check.** Manual review catches obvious edits but not field-level pixel manipulation or synthetic generation. TamperCheck runs 200+ forensic checks on a construction draw request and returns a risk score from 0 to 100 in about a minute, at $0.50 per document. ## Frequently asked questions ### How do lenders check a contractor's draw request? By reconciling the continuation sheet, summary, and prior application before anything else, then inspecting the site. The paper checks are arithmetic: completed totals, percentages, retainage, and previous certificates carried forward. A forensic review adds whether any number on the form was typed after the form was generated. ### What is edited on a construction pay application? Most often the percent complete and the work completed this period, then the totals that depend on them. Stored materials and retainage are the next favourites. Less often the certification and notary blocks are replaced with ones from a previous approved application. ### What is the difference between a G702 and a G703? The G702 is the one-page summary of the contract sum and payment due. The G703 is the continuation sheet listing each line of the schedule of values. The summary's figures should be the sums of the G703 columns, which makes the pair a self-checking document. ### Can TamperCheck tell whether a draw request was altered after it was signed? It tests whether the printed figures and the signature block belong to the same document generation. Numbers set after the fact tend to differ in font metrics, spacing, and compression from their surroundings, and TamperCheck reports the specific fields and regions concerned. ## Related document types - Loan Statement: https://tampercheck.ai/documents-support/loan_statement - Loan Sanction Letter: https://tampercheck.ai/documents-support/loan_sanction_letter - Amortization Schedule: https://tampercheck.ai/documents-support/amortization_schedule - Loan Payoff Statement: https://tampercheck.ai/documents-support/loan_payoff_statement - Loan Closure Certificate: https://tampercheck.ai/documents-support/loan_closure_certificate - Closing Disclosure: https://tampercheck.ai/documents-support/closing_disclosure --- Try TamperCheck now: https://tampercheck.ai/dashboard · Docs: https://tampercheck.ai/docs · Pricing: https://tampercheck.ai/pricing
