Cornerstone Civil Engineering Phoenix, Arizona

Every city needs a fixed point.

Infrastructure design, transportation engineering, water resources, construction management and land development — measured from one control point for public agencies and private developers.

01 — Services

Five lines of work, set from one point.

We fix the survey, the constraints and the agency requirements first, then carry that same line of reference through every discipline on the job. One team, one coordinate system, from concept to closeout.

Cornerstone takes a site from raw ground to built asset: survey and control, engineering documents, agency review and construction observation — with a single point of accountability between the owner, the design team and the contractor.

01

Infrastructure design

Water, sewer, drainage and roadway infrastructure for public agencies and private development, from concept through construction documents.

000°
02

Transportation engineering

Corridor, intersection and street design that keeps people and freight moving through a fast-growing desert city.

072°
03

Water resources

Flood control, drainage and water systems engineered for a place that measures every drop.

144°
04

Construction management

Observation, coordination and documentation through construction, so what was designed is what gets built.

216°
05

Land development

Grading, utilities and site infrastructure that turn raw desert parcels into buildable land.

288°

02 — Disciplines

Where we set points.

One coordinate system, four disciplines. A corridor, a drainage channel or a raw parcel is held to the same control points and the same standard of record.

PT-01 · Transportation

Corridors that carry a growing city.

Corridor, intersection and roadway design for metro Phoenix — alignment, drainage and utilities coordinated from first sketch to construction documents.

PT-02 · Construction management

The built work matches the documents.

Our engineers stay on the job through construction, so decisions made in the field trace back to the drawings they came from.

Field observation & reporting
Contractor & agency coordination
Closeout documentation

Concrete-lined water canal and drainage channel running through desert landscape

PT-03 · Water resources

Water systems for a desert city.

Flood control, drainage, hydrology and water infrastructure designed for a place where every drop is accounted for.

PT-04 · Land development

Raw parcels into buildable land.

Grading, utilities and site infrastructure that make a desert parcel shovel-ready, coordinated with the agencies that review it.

Public agencies

Municipal and agency work held to published standards, with documentation built for review.

Private developers

Site infrastructure and entitlements coordinated around a developer's schedule.

03 — Process

From control point to closeout.

Every project runs on a station line. Ours starts with the site and the agencies involved, and ends with a built, documented asset handed over clean.

STA 0+00
Set the control point

Site, constraints, agencies. Scope, budget and schedule are fixed before design begins.
STA 0+50
Draw the line

Engineering and construction documents, with roadway, drainage, water and utility work coordinated across disciplines.
STA 1+00
Clear the path

Permitting, agency review and stakeholder coordination with the city, county and utility owners involved.
STA 1+50
Hold the line

Construction management through to closeout, so the built work matches the documents it was built from.

04 — Contact

Bring us the site.

Send the location, the scope and the agencies involved. We will come back with an approach, a schedule and one point of contact for the work.
