# Pini Liberman on estimates grounded in the project documents

1. Strong pricing starts with knowing the project inside and out
2. Manual review still left room for blind spots
3. Findings stay grounded in the project documents

Pini Liberman is CEO of a $3B general contractor. This page records the account already published on the Piper homepage. It does not add metrics that were not in that quote.

## Situation

In construction, strong pricing starts with knowing the project inside and out.

## Before Piper

That required an impossible amount of manual review and still left room for blind spots.

## What changed

Piper does the heavy review work, flags risks early, and gives the team confidence that estimates are grounded in the project documents.

## Result

The published account is qualitative: helping win work while protecting margin. Piper has not published a numbered before-and-after for this team on this page.

## Proof

> In construction, strong pricing starts with knowing the project inside and out. Before Piper, that required an impossible amount of manual review and still left room for blind spots. Piper does the heavy review work, flags risks early, and gives us confidence that our estimates are grounded in the project documents, helping us win work while protecting margin.
