Tier-One Pre-Construction Group

The First Thirty Days
Determine Everything.

Pre-Construction Excellence · Program Management Discipline · Federal & Commercial

"Construction is built on paper before it is built in the field. Every dollar lost on a job traces back to a decision — or the absence of one — made in the first thirty days."

The Problem

Pre-Construction Is Treated as a Formality.
It Is Not. It Is a Discipline.

In 65 years across federal agencies, hospital systems, power plants, nuclear stations, missile silos, commercial towers, and residential subdivisions — one pattern repeats without exception. Projects fail because of what did not happen before construction started. The window between Notice to Proceed and boots on the ground is the most valuable time on any project. Most organizations waste it.

Without Pre-Construction Discipline

  • RFIs generated to answer questions that should have been answered before NTP
  • Submittals processed reactively — holding up procurement and field operations
  • Schedule baseline built after mobilization — no real critical path identified
  • Scope gaps discovered in the field — change orders follow every time
  • Division 01 requirements misunderstood — compliance failures compound
  • Risk register is a template — project-specific risks never identified
  • Closeout documentation assembled under pressure — deficiencies found too late

With Tier-One Pre-Construction

  • All foreseeable RFIs resolved before NTP — field operates without interruption
  • Submittal register complete at NTP — procurement on schedule from day one
  • CPM baseline before mobilization — critical path is known and managed
  • Scope fully defined before commitment — change orders are exceptions not norms
  • Division 01 integrated into budget and schedule — compliance built in
  • Risk register is project-specific — mitigation plans ready at NTP
  • Closeout structure established at NTP — documentation current throughout
The Methodology

Seven Phases. NTP to Boots on Ground.
Principal Does the Work. Every Time.

The Tier-One methodology is not a template — it is a discipline earned over 65 years and applied in its entirety on every engagement. All seven phases are delivered by the principal before field operations begin.

01
Scope Intelligence & WBS Development
02
CPM Schedule Development & Baseline
03
Division 01 General Requirements Integration
04
Schedule of Values Construction
05
Risk Register Project-Specific Assessment
06
Procurement & Submittal Management
07
Earned Value Management Framework
Case Study

Lincoln Memorial Reflecting Pool
Washington, DC — Methodology in Practice

The most documented independent pre-construction analysis ever prepared for a federal project outside the contracting chain. Every prediction confirmed. The government's own survey firm found conditions that matched the Tier-One field observation report — almost word for word.

The Credential

65 Years From the Ditch to the Program Office.
Starting at Age 12.

The authority behind Tier-One's methodology is not academic. It is biographical. Every framework applied was tested — and earned — through six decades of direct engagement with the systems, the failures, and the solutions that construction produces.

The Conversation We Want to Have

Pre-construction is not a cost. It is an insurance policy with a guaranteed payout. The question is not whether you can afford Tier-One. The question is whether you can afford the alternative — and what the last project that skipped it actually cost you.
