Make difficult sites buildable.

Site and soil evaluation, earth-retention design, permit coordination, and field support across Orange County and Los Angeles.

A carefully terraced residential hillside site above the Southern California coast

If the site can change the project, start there.

A difficult site is not a project type. It is any property where the ground, the cut, the access, or the neighbors can change design, permitting, cost, or construction.

Start with the site
Slope
Excavation
Access
Groundwater
Nearby structures
Retaining systems

From site question to field answer.

Each scope resolves the next decision without pretending every project needs the same path.

Review the site

Plans, photos, maps, access, neighboring structures, and missing information become a written decision list.

Evaluate the ground

Field information and qualified reporting establish the criteria the design needs to respect.

Select the system

Shoring, retaining, grading, or foundation direction is coordinated before permit documents are released.

Answer the agency

Comments and revisions stay connected to the selected system, the site, and the project team.

Support the field

Observations and design questions are handled within the agreed scope as site conditions become visible.

Start with the decision you need.

Begin with a paid site review, then add only the technical scopes the property and project require.

Start with the real constraint

Paid site review

A focused review of the property, intended work, available plans, photos, access, adjacent structures, and known site conditions.

Best fit
Early land decisions, a stalled design, an unfamiliar slope, or a project that needs a technical path before more money is committed.
Bring
Property address, intended work, plans or sketches, site photos, known reports, timing, and permit status.
Receive
A written constraints and information list, recommended next scope, and a preliminary path forward.

Project conditions we support.

These images are visual placeholders. Replace them with verified Strucal case studies showing the starting condition, exact duty, permit result, and construction result.

Terraced hillside construction site near the coast

Hillside and coastal sites

Slope, access, drainage, excavation, and neighboring properties can change the project path early.

Excavation work on an active construction site

Deep excavations and basements

Projects that remove lateral support need a coordinated earth-retention and construction sequence.

Concrete structural work on a construction site

Retaining-wall repair

Movement, distress, or replacement starts with understanding the site condition and the next defensible step.

Compact contemporary residential building

Difficult homes and ADUs

Custom homes and ADUs stay in focus when soil, slope, access, or retaining work makes the site technically demanding.

Exposed structural frame on a constrained building site

Rebuilds and constrained infill

Existing neighbors, limited access, and incomplete site information call for an early technical path.

Clarity at every handoff.

The working model keeps site information, selected systems, permit responses, and field questions connected without blurring who owns each duty.

A paid first step

Define the property, intended work, missing information, and the next useful scope before design expands.

Connected technical decisions

Carry the accepted site criteria into earth-retention, permit, and construction questions when those scopes apply.

Written responsibility

State inputs, exclusions, approval points, outside duties, and the change process for each engagement.
