What information do you need to start a foundation plan?

A geotechnical report, structural loads or an engineer's design criteria, and an architectural or existing-condition plan showing the building footprint.

Licensed Foundation Plan Drafters

100% Accurate Foundation Plan Design Services

Q: Do you offer foundation plan design services for both new construction and repair?

Yes, foundation plan design services are provided for new-construction foundations and for settlement repair projects, including helical pile and micropile underpinning of existing structures.

Q: Can you draft foundation plans for a house-raising or flood elevation project?

Yes, house-raising foundation plans are produced detailing helical pile placement, temporary cribbing pick points, and finished floor elevation relative to base flood elevation.

Q: Do you provide foundation structural calculation services, or only drawings?

Foundation structural calculation services are provided that support the plan, including bearing and pile capacity checks, but final calculations are reviewed and stamped by the client's engineer of record.

Q: Do you design post-tension foundations for expansive soil?

Yes, post-tension foundation design drawings are produced detailing tendon layout and stressing sequence for slabs on expansive or poor-bearing soil, coordinated to PTI design criteria.

Q: Do you stamp or seal foundation plans?

No. CAD Drafter is a foundation plan design company, not a licensed engineering office. Plans are prepared for the client's engineer of record's review and approval.

CAD Drafter’s foundation plan design services translate your geotechnical report and structural loads into buildable foundation drawings across helical piles, micropiles, concrete foundations, and house-raising retrofits, for wood, LGS, and concrete structures alike.

From a single pier and beam replacement to a full commercial slab package, our drafting team works from your engineer’s calculations and soil data to produce foundation plans, grade beam layouts, and pile schedules ready for permit submittal or field installation.

Our Structural Foundation Design Services

CAD Drafter is a foundation plan design company, not a geotechnical lab and not a stamp-issuing engineering office. Homeowners, contractors, foundation repair specialists, and structural engineers of record send us soil reports, load data, and repair scope. In return, we draft the foundation plans, pile layouts, and reinforcement details your engineer reviews and your crew builds from.

Why Contractors Outsource Their Foundation Plan Drafting

A flat-rate quote, a defined revision cycle, and a drafting team that already knows the difference between a helical pile bracket detail and a micropile-to-footing connection, without the overhead of adding a permanent drafter to your payroll.

Our Client-Focussed Foundation Plan Design Services

From helical piles to post-tension slabs, every foundation plan is drafted from your engineer’s design criteria and soil report, then detailed for the material system your project is actually built in.

Helical Pile Foundation Design

Layout drawings showing lead section and extension placement, helix configuration, target installation torque, and bracket-to-grade-beam connection details for new construction and settlement repair, referenced to the manufacturer’s ICC-ES evaluation report.

Micropile Foundation Design

Casing size, grout column length, and threaded bar detailing for micropile-to-footing and micropile-to-grade-beam connections, sized for sites where access is tight or nearby utilities rule out a driven pile or spread footing.

Concrete Slab Foundation Design

Slab-on-grade, mat, and turned-down footing plans with reinforcement layout, control joint spacing, and thickened-edge details sized to soil bearing capacity and frost depth for the project’s jurisdiction.

Post-Tension Foundation Design

Post-tension cable layout and stressing sequence drawings for slabs on expansive or poor-bearing soil, detailed with tendon profiles, anchor locations, and stressing tail clearances coordinated to PTI design criteria.

Crawl Space Foundation Plans

Perimeter stem wall, pier spacing, and ventilation layout drawings for vented and unvented crawl space foundations, coordinated with beam pockets and access openings for wood and LGS floor framing above.

Basement Foundation Engineering Services

Foundation wall thickness, rebar placement, and lateral earth pressure detailing for below-grade basement walls, coordinated with waterproofing, drainage, and egress window well requirements.

Our Process

How CAD Drafter Delivers Foundation Plan Design

Our drafting workflow is built around one goal: a foundation plan your crew can excavate, form, and install piles from on the first release. Here’s the 4-step process our drafters follow:

Soil Report & Load Review

We review your geotechnical report, structural loads, and repair or new-construction scope, confirming the foundation system before drafting starts.

Package Quote & Timeline

You receive a scoped price and a release date broken down by foundation plan, pile layout, and detail sheet milestones.

Drafting & Internal QC

Our drafters produce the plan set and pass every sheet through an internal dimension and cross-reference check before it reaches your desk.

Release & Revision Rounds

You receive editable plan files, with revision rounds included per your project’s drafting agreement.

Why Choose Us

Why Builders & Foundation Repair Contractors Choose CAD Drafter

Homeowners, contractors, and structural engineers keep sending us their foundation drafting scope for a specific reason. Unlike other foundation plan design companies working off a single footing template, our drafters detail to the soil, the material system, and the repair method your project actually needs.

We Draft, Your Engineer Confirms

We never alter design intent. Every foundation plan carries the bearing capacity, pile capacity, and reinforcement criteria your engineer of record issued, ready for their review and stamp.

Code-Referenced Foundation Drafting

Sheets reference IBC 2021, IRC 2021, ASCE 7-22, ACI 318, PTI DC10.5, and applicable ICC-ES evaluation reports for the material and jurisdiction.

Residential & Commercial Range

Residential foundation engineering for single-family and multi-family homes, alongside commercial foundation design services for retail, office, and industrial developers.

Scalable Drafting Capacity

Take on a single pier and beam repair plan or a full commercial foundation package without adding headcount to your own drafting floor.

Software We Use

Benefits Of Outsourcing To The Team

Why Firms Choose Outsourced Foundation Plan Drafting

Keeping a foundation drafting seat staffed year-round is expensive against a repair and new-construction pipeline that swings with the season and the weather. Outsourced structural foundation design services let contractors and engineers flex drafting capacity without carrying it as fixed overhead.

Lower Drafting Overhead: A per-plan-set rate instead of a salaried foundation drafter on staff.

Faster Plan Release: A dedicated drafting team means your foundation plans aren’t waiting behind someone else’s project. Standard packages release in 24-48 hours.

Built-In QC Review: Every plan passes an internal dimension and cross-reference check before it reaches your desk for approval.

Do you provide foundation structural calculation services, or only drawings?

We provide foundation structural calculation services that support the plan, including bearing and pile capacity checks, but final calculations are reviewed and stamped by your engineer of record.

What’s the difference between a helical pile and a micropile?

A helical pile is a steel shaft with helix plates screwed into the soil, while a micropile is a smaller-diameter cased or grouted pile with a threaded bar, typically used on sites with tight access or nearby utilities.

Do you design post-tension foundations for expansive soil?

Yes. We produce post-tension foundation design drawings detailing tendon layout and stressing sequence for slabs on expansive or poor-bearing soil, coordinated to PTI design criteria.

Do you stamp or seal foundation plans?

No. We are a foundation plan design company, not a licensed engineering office. Plans are prepared for your engineer of record’s review and approval.
