Straight talk: the lanes on a job

Who Does What on a Poway Foundation Project

A foundation repair can involve five or six parties. Each one has a lane. Here's who they are on a Poway job, what each one signs or checks, and what stays on your plate.

Foundation work in Poway can get crowded. A soils firm. An engineer. A contractor. A plan checker. An inspector. Maybe a special inspector. And you, the owner, paying for all of it.

People get confused about who’s in charge of what. That confusion costs time and causes friction. So here it is, lane by lane. Plain and short.

You, the owner

You own the property. You own the decision.

Your job:

  • Decide what you want looked at and fixed
  • Hire the right people, and check them out
  • Give access and share any records you have
  • Sign the contracts and the permit applications as required
  • Keep copies of everything

You also hold the history. Old permits, an as-graded report, a past repair. Bring them. Our posts on searching Poway records and the as-graded report show where to find them.

The soils side

Before anyone designs a repair, someone may need to understand the ground. That’s geotechnical work. It means borings, lab tests and a written report on how the soil behaves and what it can carry.

On a Poway hillside, a fill lot or a slope problem, this often comes first. The foundation design depends on it. You can’t size piers or footings without knowing what they bear on.

If there’s slope stability or geology in question, an engineering geologist may be part of this lane too.

The engineer

The engineer turns the problem into a design. On foundation work that’s typically a civil or structural engineer licensed in California.

The Professional Engineers Act lists foundations, grading and buildings among the fixed works that civil engineering covers. It says civil engineering documents, including structural and geotechnical plans, calculations, specifications and reports, are to be prepared by or under the responsible charge of a licensed civil engineer. Plans released for construction carry that licensee’s signature and seal or stamp.

What that means for you: on a job that needs engineering, the drawings the City reviews carry a licensed engineer’s signature. That person is responsible for the design.

The engineer doesn’t automatically run the job site. Whether they visit during construction, review submittals or observe key steps depends on the agreement you sign with them. Ask what’s included.

When an engineer is required

Not every job needs one. The Act has a section that allows plans for some simple wood-frame houses to be prepared without a licensed engineer or architect. It covers single-family wood-frame dwellings up to two stories plus a basement. But it adds a catch. If any part of the structure departs from conventional framing, the building official is to require that part to be prepared by a licensed engineer or architect, stamped and signed.

Poway’s building page says something similar in its own words. For a new home, addition or remodel, a qualified person such as a drafter, building designer, architect or engineer needs to prepare the plans. Some items built to City standard details only need a plot plan.

Foundation repair usually isn’t conventional framing. Underpinning, piers, new footings on a slope and retaining walls generally call for engineering. Grading does too. Poway’s grading page says you’ll need a qualified professional engineer to prepare a grading plan when a grading permit is required.

The contractor

The contractor builds it. In California that means a contractor licensed by the Contractors State License Board for the type of work.

CSLB issues different classifications. Some contractors hold a general engineering license, some a general building license, some a specialty license. The classification should fit the work. The CSLB’s Hire a Contractor page lays out the basics: check the license, get a written contract, and don’t pay more than the law allows up front.

What the contractor does:

  • Prices and schedules the work
  • Pulls permits when the contract says they will
  • Builds to the approved plans
  • Calls for inspections
  • Manages crews, subs and the site
  • Flags field conditions that don’t match the plans

What the contractor doesn’t do is change an engineered design on their own. If the dig uncovers something unexpected, the contractor stops and talks to the engineer. That’s how we work. We build foundation repairs, and we coordinate with licensed engineers as needed for design, field changes and sign-offs. Our foundation repair page explains the kinds of work involved.

The City: plan check and inspection

The City of Poway is not on your team or ours. It’s the referee.

Poway’s Building Services page says the City contracts with EsGil Corporation for plan check and inspection services. Plan check reviews the drawings against the codes. Inspectors visit the site at set stages to confirm the work matches the approved plans.

Plan check and inspection protect the public. They’re not a design service, and they don’t stand behind the quality of your project. They check for code compliance at the points they inspect.

Special inspection

Some work needs more eyes. The California Building Code, in Chapter 17, requires special inspections and tests for certain kinds of construction. Concrete, reinforcing steel, soils, drilled piers and some anchor work can fall in that list, depending on the project.

A special inspector is a qualified person who watches specific operations and reports on them. On some jobs, the soils engineer’s field staff observe excavations and footings. The approved plans and the building official set what’s required.

If your job has special inspection, it’ll be listed on the plans or the permit. Budget for it. Plan the schedule around it.

Do’s and don’ts for owners

Do:

  • Ask each party what’s in their scope, in writing
  • Check every license
  • Keep one folder for reports, plans, permits and inspection cards
  • Ask who to call if something changes in the field

Don’t:

  • Let anyone skip the soils work if the engineer wants it
  • Approve field changes without the engineer’s input
  • Assume the City inspector is checking quality for you
  • Start work before the permit is issued when one is required

Where we fit

We usually come in early. You call about cracks, a slope, a sloping floor. We evaluate. Our foundation inspection page covers that step. If the fix is simple, we tell you. If it needs soils work or engineering, we say so and help pull the team together.

Then we build it, call the inspections and keep everyone talking. If you’re still at the stage of watching a crack, start with our monitoring guide.

What shapes the job

  1. Whether soils work or geology is needed first
  2. Whether the repair needs engineered drawings
  3. Grading and building permit requirements
  4. Special inspection items
  5. Access on the lot, especially on slopes
  6. Field conditions found once digging starts
