One question per row, written out. Jump to a specific tool from the directory on the left. If yours isn’t here, reply to any email from us and you reach Hammad directly.

General

What is Prevaldi?

Two things. The free browser tools — quick, single-purpose drafting and review utilities for solo lawyers and small construction firms. And the written practice reviews — 10 to 14-page PDF audits of how your operation actually runs, delivered by email within 48 hours of an intake form. No calls, no Zoom, no sales cycle.

Who is behind it?

One person — Hammad Arain, the founder. The reviews are written by Hammad directly. The tools are built and maintained by Hammad. There is no team of associates or contractors behind the byline.

What happens to what I paste into a tool?

Tool inputs are sent to Anthropic's API to generate the response and are not retained on Prevaldi servers beyond the request. We log a hashed IP address for rate-limit accounting and the tool slug. We do not store the text of your prompt, your output, or any identifying details. Don't paste anything privileged or confidential — redact names and numbers first.

Why is the practice review free?

Prevaldi is new and we need case studies. The scope and quality match the eventual paid version — only the price changes. We'd rather earn a reputation by writing thirty good reviews than by selling thirty mediocre ones.

How do I reach a human?

Reply to any email from us and you reach Hammad directly. There is no support queue, no ticketing system, no shared inbox. Replies typically get a written answer within a day, always in the same email thread.

Do the tools cost money?

No. The browser tools are free while in beta. Each tool is rate-limited (about 10 runs an hour per visitor) so they stay free without us subsidising abuse. If you hit the limit, the page tells you to come back in an hour.

Will you sell my email or add me to a list?

If you submit an audit intake or sign up for a tool's nurture sequence, you'll get a small number of emails from us about that specific thing. You can unsubscribe from any email with one click. We don't sell or share lists, and we don't run cross-vertical email campaigns.

What if I find a bug or have a feature request?

Reply to any email from us, or email [email protected]. Bugs get fixed; feature requests get a real answer about whether and when. Prevaldi is small enough that we read everything that comes in.

Practice and operations reviews

The free 48-hour written reviews — one for solo lawyers, one for small construction firms — and the focused paid audits that sit alongside them.

Construction Operations Review

Who writes it?

One person — Hammad Arain, the founder, with input from contractors active in the early review pool. Not a team. Not generated by an AI model and shipped without review.

Will you contact me after?

Only if you reply. Reply, and you get a written answer in the same thread. Don't reply, and you don't hear from us — no nurture, no calls, no “checking in.”

What if my answers raise more questions?

We email one batch of clarifying questions before writing. Answer at your pace; the 48-hour clock resumes when you reply.

What if I want changes to the report?

Reply to the delivery email. Factual corrections get a revised PDF within 24 hours. Disagreements with a recommendation stay in the report — we'd rather you have the full reasoning to push back on than a sanitized version.

Why is it free?

Prevaldi is new and we need case studies. The scope and quality match the eventual paid version — only the price changes.

Construction tools

Free browser tools for GCs, estimators, and sub-trades. Plus the paid focused audits — Estimate Review, Change Order Audit, T&M Leak Audit, and the Enterprise Operations Review for $25M+ shops.

Addendum Digest

What does the Addendum Digest do?

Takes the text of a bid addendum and pulls out every change — scope, cost, schedule, document revisions, deadline shifts. The output is a checklist of what's actually different and a flagged list of items you need to re-quote before the bid deadline.

Will it cross-reference changes against the original plans?

No. The Digest reads the addendum text on its own. It tells you what the addendum changed; whether that change conflicts with a detail on Sheet A-301 you bid against is your job to verify. Use this to triage what's worth a re-read, not to skip the re-read.

What if the addendum is 40 pages?

Paste it. The tool is capped at 50K characters of input, which is roughly 80 pages of normal text. For addenda longer than that, paste the “what changed” section and the spec/drawing change list — those are the parts the Digest extracts from anyway.

Will it catch every change?

It catches stated changes — anything the addendum explicitly calls out. It will not catch implicit changes (a revised drawing that contradicts an unrevised spec section, for example). The Digest is calibrated to surface what the GC wrote; what the GC accidentally left out is on you to spot.

Should I paste this in before or after my own read?

Before. Run the Digest first to get a structured map of what's in the addendum, then do your own read against the map. Subs who read addenda cold often miss the same kinds of changes (scope reassignments, allowance/covered swaps, schedule shifts hidden in the cover letter). The Digest closes that gap.

See the tool: /construction/addendum-digest

Audit Bundle (Estimate + Change Order)

What does the Audit Bundle include?

The Estimate Review and the Change Order Audit, delivered together as a single combined PDF. Same scope as ordering both individually; one engagement, one fee.

Why these two together instead of separately?

Margin leaks at the front of the job (bids that undercount scope) and at the back of the job (change orders that fail to capture approvals) are connected. Every undocumented change order has a corresponding scope gap that should have caught it during estimating. Looking at both processes in one engagement makes the pattern visible.

What's the typical recovery range?

Combined recoverable typically exceeds $50,000/year on a $5M operation. The bundle is $19,999 one-time — the math is direct on a typical small GC.

What do you need from me to run it?

Three to six recent bids you've submitted, three to six change orders that ran on those jobs, and a written description of your estimating and change-order processes. We don't need contract values, customer names, or anything privileged — the audit reads the patterns, not the parties.

How fast is delivery?

PDF in your inbox within 10 business days of the intake form. One round of clarifying questions if your intake leaves anything ambiguous — the clock pauses until you reply.

See the tool: /construction/audit-bundle

Bid Leveller

What does the Bid Leveller do?

Takes sub bids in any format — pasted email body, copied spreadsheet rows, PDF text — and produces a normalised comparison table. Each bidder's scope, exclusions, allowances, and price laid out so you can see what each one actually included and what they quietly left out.

Does it calculate the total project cost?

No. The Leveller compares scope, not budget. It tells you that Sub A excluded fire-stopping and Sub B included it; it doesn't roll a project total because that depends on the rest of your bid you didn't paste in.

What's the most useful output?

The scope-gap section. The “Sub C is $4K cheaper than Sub B” line is obvious; the “Sub C excluded permit fees and rough-in coordination” line is what saves you from awarding the wrong bid and eating the gap.

What about unit prices?

Out of scope. The Leveller compares scope and totals, not unit-price reasonability. For unit-price validation (“is $4.20/SF for X reasonable for our market”), you need historical bid data the Leveller doesn't have.

What format should I paste the bids in?

Whatever you have. Pasted email body, copied table, exported PDF text — the Leveller is built to handle inconsistent formats because that's what real sub bids arrive in. If a bidder sent a one-page proposal and another sent a 12-tab spreadsheet, paste both. Cleanup is what the tool does.

See the tool: /construction/bid-leveller

Change Order Memo

What does the Change Order Memo tool produce?

A formal written change order memo from a plain-language description of the change. Scope, cost impact, schedule impact, signature block — the structure a GC expects to see before approving and the structure a customer recognises as a real change order rather than a text message.

Will this hold up legally?

The memo gives you the structure courts and contracts treat as a written change order. Whether your specific contract requires additional formalities (signatures from both parties, prime-contract notice provisions, lien-waiver attachments) is contract-specific. The memo is the minimum upgrade from a text-message approval; a contract attorney should review your standard form before you adopt it firm-wide.

What if the change was already verbally approved?

Exactly the use case. The memo turns the verbal into a written record before the GC denies the approval ever happened. Send the memo within 24 hours of the verbal — speed matters more than perfection. The pattern that loses disputes is approval-by-text-with-no-follow-up-paper.

What inputs do I need?

What changed, why it changed (RFI response, field condition, GC direction), the cost impact, the schedule impact, and the parties involved. The tool fills in the boilerplate — the substance is what you bring.

Is this the same as a Pending Change Order (PCO)?

Close. The output is a written CO ready to send for approval. Whether you label it PCO, COR, or CO depends on your GC's terminology and your contract; the structure is the same. Edit the header to match the convention your GC uses.

See the tool: /construction/change-order

Change Order Audit

What does the Change Order Audit look at?

Your change-order documentation practice across three to six recent jobs. Where verbal approvals are turning into “I never agreed to that” weeks later, where the paper trail breaks, what your current process can and can't defend in a dispute, and the minimum upgrade that holds up.

Why this audit specifically?

Change-order chaos is widely cited as 3–4% of margin lost per project on mid-size construction firms. On a $5M operation that's $150,000–$200,000 a year. The audit names the specific pattern your operation uses today and the specific gaps that are costing you that margin.

What do you need from me?

Three to six recent change orders that ran on real jobs (redacted is fine — names and numbers can be placeholdered), a written description of how COs typically flow in your operation, and the contract size range you typically work. We don't need contract values, customer names, or signed copies.

How fast is delivery?

PDF in your inbox within 5 business days of the intake form. One round of clarifying questions if anything is ambiguous — the clock pauses until you reply.

What does it cost and what's the math?

$9,999 one-time. On a $5M operation losing 3% to change-order leakage ($150K/year), the audit pays for itself if it recovers 6.5% of that leak — a low bar on most operations. If you're below $2M in volume, the math gets tighter; talk to us first about whether this or the smaller T&M Leak Audit is the right size.

See the tool: /construction/change-order-audit

Enterprise Operations Review

Who is the Enterprise Operations Review for?

GCs running $25M+ in annual volume across multiple project types or offices. The standard 10–14 page Operations Review is sized for a lean firm with one or two project types; at this scale, process variation by office, client segment, and trade is what hides the largest leaks.

Why is the price meaningfully different from the smaller reviews?

At $25M+ in annual volume, a 1% margin recovery is worth $250,000. The audit scope expands to cover that recovery surface — multi-office process variation, job-cost discipline at scale, sub coordination across trades, admin and back-office process. Delivered as a 30–50 page PDF within 10 business days.

What do you need from us to run it?

A multi-stakeholder intake covering estimating, change orders, job costing, sub coordination, and back-office process. Selected redacted bid packages, change orders, and job-cost reports from recent work. A scoping call to confirm what the audit will and won't cover — this is the only Prevaldi product with a synchronous scoping call.

What's not in scope?

Not an audit of your construction itself (quality, safety, schedule performance). Not a financial audit (your CPA does that). Not a software selection engagement (although the report flags overlaps and gaps in your existing stack). The Enterprise Review is an operations review of how the work flows, sized for firms whose operations are too varied for the smaller standard review.

Can we engage on a single office or division?

Yes. Some clients run the Enterprise Review on a specific office or division as a pilot before scaling it across the firm. Pricing scales accordingly — talk to us at intake about whether a full-firm or a single-division engagement makes more sense.

See the tool: /construction/enterprise-review

Estimate Review

What does the Estimate Review look at?

Your estimating process across three to six recent bids. Where your bid template hides ambiguity, where scope gets undercounted, which specific phrases your subs read differently than the GC does. The audit names the language patterns showing up on bids you lose AND on jobs that go over.

Why bid review instead of takeoff review?

Because takeoff is a quantity-counting problem (Prevaldi doesn't read plan PDFs and produce quantities; that's a different hard problem). Bidding is a process problem — how the bid is structured, what gets included by default, what gets excluded, how addenda get folded in. Process gaps are where the audit finds margin.

What do you need from me?

Three to six recent bids you've submitted on real jobs (redacted is fine), a written description of your estimating process, and your bid template. We don't need bid totals, customer names, or signed contracts.

How fast is delivery?

PDF in your inbox within 5 business days of the intake form. One round of clarifying questions if anything is ambiguous — the clock pauses until you reply.

What does it cost?

$12,000 one-time. Subs and small GCs have publicly described missing $7K-scale scope items on individual bids; the audit is priced to pay for itself on the next two cycles where it surfaces a gap before bid day rather than after.

See the tool: /construction/estimate-review

Scope Gap Scanner

What does the Scope Gap Scanner do?

Reads plan notes or spec sections and flags what's missing — scope not assigned to a trade, coordination handoffs not addressed, code items buried in the spec that nobody assigned. The output is a structured list of gaps and commonly-missed items for the trade you're bidding.

Is this a substitute for a full plan review?

No. The Scanner reads the specific notes you paste — it doesn't have the plans, the other spec sections, or the drawings. It catches what you missed in the section you're staring at; the comprehensive plan review is still your job.

What text should I paste?

The plan notes, the spec section, the scope-of-work text, the room finish schedule — whatever has the words that describe what's expected. The Scanner reads the language. Drawings, schedules, and details that are only in PDF graphics won't help it.

Will it tell me whether the scope is constructible?

No. Constructibility is a different problem — sequence, conflict, means-and-methods. The Scanner catches what's missing from the words; the question of whether the words describe something buildable is on you.

Will it confirm code compliance?

No. The Scanner flags code items that aren't called out in the scope (e.g. “the spec doesn't mention fire-stopping at penetrations but the assembly described requires it”). It doesn't certify that the code references it flags are current for your AHJ. Treat code flags as “go look at this,” not “this is the rule.”

See the tool: /construction/scope-gap

Sub Scope Letter

What does the Sub Scope Letter tool produce?

A written scope letter ready to send to a subcontractor. Project, sub trade, scope of work, start date, site contact — laid out in the format a sub recognises and a court would accept as a written record of what was agreed.

Is this a substitute for a subcontract?

No. The output is a scope letter — useful for early-stage coordination, for confirming what was agreed verbally, and for clarifying scope before a full subcontract is signed. The substantive subcontract terms (insurance, indemnification, payment, lien provisions) belong in a subcontract a construction attorney drafts.

When should I use this?

Early in the job, before the formal subcontract is in place. Right after a verbal handshake. When a sub starts work and you want a written record of what they're supposed to be doing. Anywhere the alternative is a text-message scope description.

What inputs do I need?

Project name and location, the sub's trade, the scope of work (be specific — “electrical” isn't enough; “rough-in for first-floor receptacles and lighting per Sheet E-201” is), the start date, and your site contact.

Should I send this in addition to or instead of an email?

Both. Send the letter as an email attachment with the body of the email recapping it briefly. The sub gets the letter; you get an email trail with the letter attached for the dispute file.

See the tool: /construction/sub-scope

T&M Leak Audit

What is the T&M Leak Audit?

A targeted written review of where unbilled time-and-materials work is leaking through your field documentation. A foreman gets a verbal go-ahead, the work happens, the change order shows up two weeks later as a vague text — the GC denies it and the labor and material is already spent. The audit names the specific points in your workflow where the leak is happening.

What's the recovery range?

Subs on public construction threads have described losing $4,000 in a single month on one crew. That's $48,000 a year per crew — thirty-two times the $1,499 audit fee. The audit pays for itself on three weeks of typical T&M leakage on most operations.

What do you need from me?

A written description of how T&M tickets typically flow in your operation, three to six recent T&M tickets that disputed (redacted is fine), and the contract size range you typically work. We don't need contract values or customer names.

How fast is delivery?

PDF in your inbox within 5 business days of the intake form. One round of clarifying questions if anything is ambiguous — the clock pauses until you reply.

When is it available?

Currently on the waitlist. Add yourself and you'll get one email the moment it ships — no nurture sequence between now and then.
