Unit Price vs. Lump Sum: Choosing a Contract Structure for Concrete Restoration

Concrete repair quantities are not fully known until the concrete is opened. The contract structure decides who carries that uncertainty and how the final number is reached.

Don't Wait 30 Years: Why Concrete Condition Reviews Should Start Before Florida's Milestone Inspection

Milestone Inspection is a regulatory milestone. Building preservation is a continuous process. A condition-informed review cycle can help boards establish a baseline, recognize change and organize the right response before statutory age.

How Are Concrete Repair Quantities Measured? From Inspection to Final Repair

You cannot control what you cannot quantify. Concrete repair quantities move from estimated to identified, verified and repaired. This guide explains how each stage is measured, documented and approved so owners can follow the scope with evidence.

Concrete Spalling in Florida Buildings: Causes, Warning Signs, and When Repair Is Needed

Spalling is visible concrete loss, but the condition behind it may extend beyond the broken surface. This guide helps Florida owners recognize what they can observe, what requires licensed professional evaluation, and how an engineered repair is controlled in the field.

What Is a Milestone Inspection in Florida? A Guide for Condominium Boards

A Milestone Inspection is a structural inspection performed by a Florida-licensed architect or engineer. This guide explains who it applies to, when it is due, how Phase One and Phase Two work, and what a board should organize if structural repairs are identified.

Parking Garage Concrete Repair: Warning Signs Building Owners Should Not Ignore

Parking structures can remain in service while localized deterioration develops at decks, ramps, joints, beams, columns and soffits. Recognizing changes early helps owners document conditions and seek the right professional evaluation without treating a visible symptom as a diagnosis.

How Much Reinforcement Has Been Lost? Understanding Residual Rebar Section in Concrete Restoration

Once concrete is opened, corrosion stops being a general observation and becomes measurable information. This note explains residual diameter, cross-sectional loss, pitting and corrosion-rate measurement — and why the Engineer of Record determines what any of it means structurally.

Your Florida Milestone Inspection Identified Structural Deterioration — What Happens Next?

A Milestone Inspection report is not the end of the process. When it identifies structural deterioration, the report becomes the basis for engineering decisions, a defined repair scope, contractor execution and documented reinspection.

Why Concrete Repair Quantities Increase After Demolition Begins

A repair drawing marks where work is expected. Removal establishes where sound concrete actually starts. The difference between those two numbers is normal, measurable and — done properly — fully documented.

What Happens After a Florida Milestone Inspection Identifies Concrete Repairs?

The inspection tells a board what a licensed professional observed. It does not tell the board how much repair there is, what it should cost, or how the work will be documented. This is the sequence between the report and the close-out package.

Why Balcony Slab Edges Demand Attention in Coastal Buildings

The slab edge is the thinnest, most exposed, most detailed line on a coastal tower — and the place where concrete repair, railing embeds and waterproofing all meet. Here is what is observable, what is not, and how the work is sequenced in an occupied building.

Parking Garage Concrete Deterioration: Why Visible Damage May Be Only Part of the Scope

A garage shows its condition sooner than a façade — and still under-reports it. Decks, ramps, beams, columns and soffits each deteriorate differently, and opening a marked area regularly establishes a different extent than the survey indicated.
