Top 10 Construction Defects

Construction defects fall into 4 major areas:

  • Design Problems
  • Material Deficiencies
  • Construction Problems
  • Geotechnical and Subterranial Problems

The first few construction defects in the list involve what is referred to as the Building Envelope, i.e. they relate to the components that define the shape structure and exterior protection elements that comprise the building.

  1. Windows- Improper lapping is sometimes blamed for leaks as well as failed or improperly installed flashings- particularly at sill ends

  2. Roofs- Badly installed flashing’s faulty installation of roof membrane are some of the causes of leaking roofs

  3. Improper Drainage- Reversed slope, i.e. towards building can create conditions that can be expensive to repair

  4. Concrete Slabs- slabs that are not properly cured or don’t have adequate compressive strength are issues that are difficult and costly to repair

  5. Decks- Failure of water barriers and or improper installation is the most common issue here. Damage can be difficult to detect until it is well advanced

  6. Electrical- a multitude of difficult to detect issues can present here including double tapping at connections. Failures can cause fires, which sometimes take years to occur, making tracing the cause difficult

  7. Plumbing- a myriad of problems from leaking pipes to improper or ineffective slope of drains

  8. Below Grade- Buried slabs can create conditions where water is introduced into the interior due to

  9. Insulation- Improperly installed or missing insulation often results in issues such as poor cooling or heating of the interior spaces

  10. HVAC- Improper location and installation of dampers, vents and ducting can result in ineffective heating or cooling and possibly even life threatening situations in the case of flammability issues

Construction Defects: Early Response Identification and Action Saves Money

Invest Your Resources Early in the Project

ARCOR-Inc. brings its expertise to all stages in the life cycle of a construction project, however, it is a company that promotes an EARLY RISK RESPONSE APPROACH. This is a departure from the old traditional approach to construction risk where typically a waiting game is played until critical problems present. Attention, action and resources should rather be invested in the areas where there is early, major risk exposure identified and where the greatest cost and time savings can be achieved.

“The Builders Have Gone Mad”

Extract from Culture of Life News2

But it is not Chinese, it was designed by crazy European and American architects. These ‘master builders’ have gone totally insane and have been building increasingly bizarre, stupid and nearly impossible to repair structures of every possible sort, all of which are basically unstable, unsound or fire traps. The arrogance of the builders is painfully at odds with the power of Mother Nature, random terrorists or simple Time passing and things degrading from new to old.


I always wince when I see the CCTV center building. It is screaming for a bad ending. It isn’t ending yet but it certainly has the air of a doomed structure since it depends on staying totally intact and carefully kept under repair in order to even exist. It won’t slowly turn into a ruin, it will destabilize very swiftly if the roof has even the slightest problems.

The building on the left is the one that is burning down right now. It looks solid but that was an illusion. It is not solid at all, it is an empty shell, actually, it is a chimney as I shall explain later. First, let’s look at the architect who built this monstrosity:

The radical thinking here is, ‘How can I build something even less stable, less sustainable than the WTC?’ I am disgusted with these people.  Frankly, a simple rectangle building does the exact same job at much less cost.  And is easier to evacuate.  Imagine being stuck in the upper stories that are supported by nothing if the building suddenly has a terminal event?  Escape is nearly impossible.  The chances of that collapsing during such an event is too high.  There are no supports over the greatest point of stress which is the outermost corner.  There is no way stress can be relieved except by falling downwards!
