Services
One offering, two delivery modes. Engineering judgment is the product — whether it arrives as consulting insight or as stamped, construction-ready drawings.
The Practice — Two Pillars, Inseparable
Consulting
The three-star pillar. Sheet pile design, cofferdam engineering, deep foundations in Bay Mud, value engineering — the judgment that makes a difficult project buildable. The PE who signs is the PE who designs.
- Steel sheet pile design — marine, flood control, land applications
- Cofferdam engineering — land and water
- Deep foundation design in Bay Mud and challenging soils
- Excavation support — soldier piles, slurry walls, tiebacks
- Temporary structures — shoring, bracing, falsework, bridge jacking
- Value engineering for heavy construction projects
- Construction engineering and field support
Supervised Working Drawings
The other side of the same coin. The judgment that makes drawings buildable. Consulting generates the insight; supervised production delivers it as stamped construction documents — built within your standards or ours, on the schedule the construction industry demands.
- Stamped construction documents for temporary structures
- Sheet pile and cofferdam working drawings
- Excavation support drawings with sequencing
- Specialty assignment drawings — one wall, one cofferdam, one piece
- Drawings produced under direct principal supervision
How Clients Engage Us
Most engineering firms describe what they do. This describes the shape of the relationship.
01 · Prime
Prime design and engineering
Full responsibility for temporary structures, cofferdams, excavation support, and similar specialty designs — concept through construction support.
02 · Second Opinion
Second opinion and peer review
Independent design checks, value engineering reviews, and constructability assessments — often catching problems before they reach the field.
03 · Overflow
Overflow capacity
Specialized support for in-house engineering teams whose plates are full. We integrate quickly, work within your standards, and hand work back clean.
04 · Specific Task
Specific-task assignments
Targeted engineering for one piece of a larger project — a single sheet pile wall, a cofferdam stability check, an expert opinion. The same attention as a large assignment.
Many of WTA's longest client relationships started with a single, narrowly-scoped task.
Field Reality
LiDAR scanning grounds the engineering.
Existing conditions are where projects succeed or fail. WTA operates a Leica RTC360 terrestrial scanner and a Leica BLK2GO mobile handheld scanner, processed in Cyclone 3DR and HxDR. Scan data feeds the consulting work — as-built verification, retrofit conditions, clash detection, and point cloud documentation — so the engineering is built on what's actually there, not what the drawings say should be there.
Scan data is delivered as part of the consulting engagement, not as a separate service line.
A Builder's Mindset
William Tucker grew up in the construction business. That upbringing shapes how WTA approaches every problem: we design for the people who actually have to build it. Means, methods, sequencing, access, and cost are part of the engineering — not afterthoughts. Contractors recognize this immediately, and it's why WTA designs get built without the back-and-forth that drives schedules and budgets sideways.
WTA's most productive work often happens in partnership with other engineers — geotechnical consultants, structural firms, design-build teams, and in-house engineering departments. We work as a peer, not a competitor.
