The Design-Build System That Protects Your Margin

Jesse Lane · 26:17 Design-Build GC Systems Watch original →

TL;DR: Design-build is the most profitable delivery model in construction — and the one that can destroy your margins fastest if you don't have systems. The key is separating pre-construction from construction into two contracts, locking scope early, and managing your architect like a subcontractor. This breaks down exactly how to run it.

Why Design-Build Is Different

Traditional design-bid-build is a relay race — architect finishes drawings, hands them off, you build. Design-build is a triathlon — you run every leg. The architect works for you. Every decision flows through your company.

That leverage is what makes it more profitable. You optimize the design for your crews, reduce labour hours, compress the schedule. But the exposure is real: the architect's mistake is your mistake. The client sees one company — yours. Systems turn the additional responsibility into additional margin instead of risk.

Phase 1: The Pre-Construction Agreement

The #1 mistake GCs make: signing a lump-sum contract before the design exists. You either guess high and lose the job, or guess low and eat the loss for 18 months.

The fix: Separate into two phases, even under one relationship.

1 Sell Pre-Construction Services Upfront

Before a single line is drawn, get a pre-construction agreement signed. Cover programming, schematic design, design development, and possibly the start of CDs. You get paid for this work — fixed fee or % of estimated construction cost. Not free. This protects margin from day one and keeps the client committed.

2 Write Bridge Language Into the Pre-Con Contract

Include language that creates a preference to move forward with you for construction — not a legal trap, but a strong expectation:

The 4 Phases of Architectural Design

Understanding these phases prevents costly decisions at the wrong time. Each phase has a specific purpose — pricing too early or making design decisions too late will kill your margin.

1. Pre-Design & Programming

Define project requirements: space, function, budget, site constraints. Establish the Program of Requirements.
  • Your move: Sell pre-con services here. Charge for feasibility and budget dev.
  • Risk if skipped: You chase a moving target the whole project.

2. Schematic Design (SD)

Concept sketches: site plan, floor plan layout, basic elevations. No detailed specs yet. ~15% of architect's work, 4-8 weeks.
  • Your move: Price alongside SD. Provide preliminary budgets in real-time.
  • If over budget: Adjust now — not later.

3. Design Development (DD)

Real details: materials, finishes, window/door types, fixture specs. Engineering kicks in. ~20% of architect's work, 8-12 weeks.
  • Your move: Get real pricing from subs based on near-fixed scope.
  • Lock design here. Changes after DD are expensive.

4. Construction Documents (CDs)

Complete drawings for permitting: floor plans, wall sections, schedules, specs, engineering. ~40% of architect's work.
  • Fast-tracking possible: Start demo/framing/MEP before CDs are 100% — but only if design decisions are locked.

Phase 2: The Construction Agreement

3 Price From Real Scope, Real Drawings

The construction agreement is based on completed design — not hope. Can be lump sum, cost-plus, or GMP. You're pricing from real drawings, real specs, real sub quotes.

How to Manage Your Architect

The architect is making decisions that directly affect your budget, schedule, and profit. Manage them the way you'd manage someone spending your money on your behalf.

4 Give Constraints Upfront

Provide: target $/sqft, preferred construction methods, material lead times, permit timeline. This prevents "beautiful but unbuildable" designs.

5 Review at Every Phase End

Hold phase-gate reviews at SD, DD, 50% CDs, 90% CDs. Include your estimator, PM, and key subs. Look for:

6 Create a Cost Feedback Loop

The architect needs to know the cost impact of their decisions in real time. The client needs to know the budget impact of their requests. Build a system where both see how design choices affect the bottom line before decisions are made — not after.

Controlling Scope Creep

Scope creep is the #1 profit killer in design-build. In design-build, the boundaries are fuzzy — a small change cascades: structural affects MEP, MEP affects schedule, schedule affects cost.

7 Establish Baseline Scope Early

Create a written scope description: square footage, room count, finish levels, quality standards. Don't specify every detail — but specify every category. The baseline is the line in the sand that every change is measured against.

8 Formal Change Order Process

Execution System

The final piece is a repeatable system so every design-build project runs the same way, not from scratch.

9 Build Your Design-Build Playbook
10 Own the Client Relationship as Trusted Advisor

Shift from being a builder to a trusted advisor. Communicate proactively — weekly updates, clear milestones, transparent cost tracking. Higher trust = higher margins. Clients who trust you don't shop around and will pay for your expertise.

Quick Reference: The Complete Contract Structure

Phase Contract Type When to Sign Key Protection
Pre-Construction Fixed fee or % of est. cost Before design starts You get paid for design-phase work
Construction Lump sum, cost-plus, or GMP After design is substantially complete Priced from real scope, not guesses

Red Flags — When Design-Build Will Eat Your Margin

Bottom line: Design-build either protects your margin or destroys it. The difference is systems. Separate the contracts, lock scope early, manage the architect actively, and build a repeatable playbook. This is how elite GCs run design-build — and how Lower Coast can too.

How To Make Tens of Millions as a GC

Jesse Lane · 43:09 Systems Scale Leverage Watch original →

TL;DR: From $1.2M → $15M in 5 years. 60 hrs/wk → 20 hrs/wk. $40/hr → $1,000/hr effective. $0 sellable value → $2–4M asset. The key is building systems so the business runs without you. This breaks down the 7 core systems and the mindset shift from owning a job to owning a company.

The Trap: Brian's Story

Brian started his company 9 years ago, grew to $1.2M/yr, then plateaued for 4 years. He was the best estimator, salesperson, problem-solver, marketer — the company was Brian. He woke at 4:47am solving problems mentally, worked 60-hour weeks, missed his daughter's soccer games.

Being indispensable feels like success, but it caps growth. If you stop, the business stops. Knowledge that lives in your head doesn't compound. A business built on one person's shoulders can only ever be as big as one person can carry.

Operational Value vs Enterprise Value

Operational Value Enterprise Value
Who runs it You — exists only while you're working Systems — runs without you
Revenue if you stop Drops to zero Keeps flowing
Effective hourly rate ~$400/hr (before expenses) ~$1,200/hr
What you own A job A sellable asset

The Leverage Equation

Leverage = Company Output ÷ Your Required Input

Contractors who make tens of millions do not work five times harder. They have five times more leverage. The goal isn't more revenue — it's more revenue per hour of your time.

The 7 Core Systems (+ HR Foundation)

Think of your company like a human body. All systems must function. Document everything so it's teachable and repeatable. Systems are not bureaucracy — they are the externalization of competence. Your best thinking preserved and repeated while you're somewhere else.

1 Marketing System — Qualified Leads on Autopilot

Not hope, but process. How qualified leads enter your business predictably.

Brian's result: Referral rate increased 40% in the first quarter just by adding tracking + asking + thanking.

2 Sales System — Turning Leads into Signed Contracts

Brian's result: Closure rate improved from 25% → 55%+. Same pricing. Better process.

3 Estimating System — Protect Margin Before the First Nail

Brian's result: New estimator (with the system) was faster than Brian ever was — because the system held the knowledge.

4 Project Management System — On Time, On Budget

Brian's result: Profit margins increased 8% — not by charging more, but by losing less through systemized project control.

5 Field Management System — Consistency Beats Heroics

Brian's result: After he stopped showing up daily, jobs ran better. Consistency beats heroics every time.

6 Office Management System — The Glue
7 Financial Management System — Scoreboard for Profit

Critical: You can't manage what you don't measure. Most contractors don't know their true job costs until the job is done — too late.

HR Foundation — People Enable All Systems

The Orchestration Layer — Making Systems Work Together

A system of systems. Systems alone aren't enough — they need leadership that:

Making Your Company Sellable

A company that runs on systems is a company someone will buy. The valuation multiple depends on:

Bottom line: A systems-built company is worth real money — often 3–5× EBITDA. Brian went from a job worth $0 to an asset worth $2–4M. The same trajectory is available to any GC who stops being the business and starts building one.
