Services
Eight services in two tracks. If you own or manage a building that is already standing, start with existing buildings. If you are building something, start with new projects. Each service says when you need it, what is included, what you receive and what to do next.

Existing buildings
You own or manage a building.
For associations, property managers and owners with a county notice, a deadline, visible distress or a repair to scope. Miami-Dade and Broward each run their own program, and each has its own page here.
01Existing buildings
Miami-Dade Building Recertification
A clear path from the Miami-Dade notice to a closed recertification — inspection, the structural report on the county’s form, repair scope, reinspection.
- When you need it
- A Notice of Required Inspection has arrived from your city or from Miami-Dade County — or a courtesy notice says one is on its way.
- What's included
- Notice review · Structural inspection · Report on the county’s form · Repair scope · Reinspection
- What you receive
- Structural recertification report on the county’s own form, signed and sealed
- Next step
- Send the notice — a phone photo is enough — or the address and the year built. We confirm what your Building Official is asking for and reply with a proposal for the inspection and the structural report.
02Existing buildings
Broward Building Safety Inspection Program (BSIP)
From the Notice of Required Inspection to the completion letter that closes the file — inspection, the structural report on the program’s official form, repair scope, reinspection.
- When you need it
- A Notice of Required Inspection has arrived from your city’s Building Official — or the building is nearing the age at which one will.
- What's included
- Notice review · Structural inspection · Report on the official form · Repair scope · Reinspection & close-out
- What you receive
- Structural report on the program’s official form, with a written narrative and color photographs, signed and sealed
- Next step
- Send the notice — a phone photo is enough — or the address and the year of the certificate of occupancy. We read what your city is asking for and reply with a proposal for the inspection and the structural report.
03Existing buildings
Milestone & Structural Safety Inspections
Florida’s milestone inspection explained for your building, further investigation when a report calls for it, and structural safety inspections outside a program cycle.
- When you need it
- Your board needs to know whether Florida’s milestone law reaches the building, and how it is met in your county.
- What's included
- Applicability review · Structural inspection · Further investigation · Prioritized findings
- What you receive
- Inspection report with photographic record
- Next step
- Tell us the building’s county, age and number of stories, and what raised the question — a notice, a report, a sale. We reply with which rules apply and a proposal for the inspection.
04Existing buildings
Structural Assessments & Repair Design
What the building is actually doing today — deterioration assessed, capacity evaluated, repairs engineered so they can be bid and built.
- When you need it
- A recertification, BSIP or inspection report lists repairs and the contractors’ bids are not comparable because nobody defined the scope.
- What's included
- Field assessment · Deterioration mapping · Capacity evaluation · Repair specification
- What you receive
- Condition assessment report
- Next step
- Send photographs of the conditions and any previous report. We tell you whether a site visit is needed and what the assessment will cover.
New projects
You are building something.
For owners, developers, architects and contractors with a project in design or heading to permit.
05New projects
Reinforced Concrete Design
Foundations, columns, beams, slabs and shear walls designed as one load path — detailed for the field and issued permit-ready.
- When you need it
- You are building a house, townhouses, a mid-rise or a commercial frame and need the structural set for permit.
- What's included
- Foundations · Columns & beams · Slabs · Shear walls · Reinforcement detailing
- What you receive
- Structural drawing set, permit-ready
- Next step
- Send the architectural drawings (any stage) and the site location. You receive a proposal with scope, deliverables and fee.
06New projects
Structural Analysis & Foundations
Gravity and lateral analysis, wind and seismic demand, and the foundation system that carries all of it into the ground.
- When you need it
- You need to know whether a site, a soil report or a building concept works structurally before committing.
- What's included
- 3D modeling · Wind & seismic demand · Drift control · Deep foundations · Settlement checks
- What you receive
- Analysis model and results summary
- Next step
- Share the site, the geotechnical report if you have one, and the building concept. We reply with what is feasible and what the analysis will cost.
07New projects
BIM Modeling & Coordination
Coordinated digital models that resolve conflicts before they reach the field and produce clearer structural deliverables.
- When you need it
- The project team works in Revit and needs the structure modeled to the same standard.
- What's included
- Structural modeling · Model federation · Clash detection · Issue tracking · Model-derived drawings
- What you receive
- Structural model at the agreed level of information
- Next step
- Tell us the software the team uses, the level of detail required and the coordination schedule. We propose the modeling scope and the exchange format.
08New projects
Peer Review & Compliance
An independent second read of the structural design — code compliance, load path, constructability and documentation quality.
- When you need it
- A lender, insurer or owner requires an independent structural review before construction.
- What's included
- Drawing review · Calculation check · Load-path continuity · Constructability · Comment log
- What you receive
- Independent review report
- Next step
- Send the drawing set and calculations, and say what the review is for. You receive a fixed-fee proposal for the depth of review that matches it.
What we design
From a single house to a mid-rise concrete frame.
The same engineer and the same detailing standard, scaled to the building in front of us. If your project is not on this list, it is worth a conversation rather than an assumption.
Photographs illustrate the kind of structure described; none shows a project by Terdax Engineering. Typical engagements are listed under Work.
How we work
Five steps. You always know which one you are on.
The sequence is the same whether you are answering a county notice or permitting a new frame. What changes is the depth of step three.
Initial consultation
Your part Send the notice, or describe the building or the project, and share what you have — photos, drawings, prior reports.
You get A direct conversation with the engineer and a first read on what is needed.
Scope & proposal
Your part Review a written proposal that states scope, deliverables, exclusions and fee.
You get A document you can compare, question and approve. Nothing starts before it is agreed.
Evaluation or design
Your part Give access to the site, or answer the architect’s coordination questions as they come.
You get Inspection and findings for existing buildings; analysis, modeling and detailing for new ones — with questions raised as they come up, not saved for the end.
Delivery
Your part Review the report or the signed and sealed drawing set, and ask about anything that is unclear.
You get Documents written to be acted on: a board can read the findings, a contractor can build the details, a reviewer can follow the reasoning.
Follow-up
Your part Forward the reviewer’s comments, the contractor’s RFIs or the reinspection request.
You get Answers from the engineer who did the work — through permit comments, construction questions and, for existing buildings, reinspection and close-out.
Next step
A county notice in your hand, a building that worries you or a new project — describe it and attach what you have. A phone photo of the letter is enough. You hear back from the engineer, with questions or with a written proposal.
