Exterior Deficiencies #2

Photo 2.1- Improper flashing detail at foundation/wall intersection. Code requires aweep screed for H2O egress at this location.

2.2- Note severe termite damage to EPS foam bands from tunneling activity to access wood components.

2.3- Exposed reinforcing fiberglass mesh observed on aesthetic expansion joints-poor workmanship.

2.4- Note EIFS lamina damage and exposed system components.

2.5- Head flashing was attempted on some openings, but improperly installed and in violation of building code.

Page 12: Inspection Report

Interior Deficiencies/Damage #1

Photo 3.1- Extensive/severe water damage and termite infestation to interior window wood trim.

3.2- Complete framing failure around openings caused by termite infestation into wet wood components.

3.4- Termites use the foam employed to insulate walls as a tunneling mechanism to access moist wood.

3.5- Substantial drywall damage with saturated conditions adjacent to side deck door.

3.6- Window sill damage was prevalent throughout the interior as a result of improper construction.

3.7- Damage was also observed on baseboards from water migration and contamination.

Photo 4.1- Black mold, possibly toxic stachybotrys, was observed on third floor ceilings in drywall material.

4.2- Water intrusion created climate conducive to mold growth observed in numerous locations.

4.3- Third location on third floor where mold growth was observed-complete removal and replacement of contaminated drywall.

4.4- Note extensive water damage to interior window trim on front elevation window.

4.5- Termite infestation to crown mold trim on interior window headers.

4.6- Note water stain on floor caused by excessive water infiltration as a result of poor construction details.

4.7- Significant damage to wood flooring from moisture ingress/contamination at door threshold.

4.8- Concrete sub-floors observed under hardwood material will be beneficial in remediation since no deterioration is possible.

4.9- Haphazardly applied caulk joint around electrical attachments.

Page 14: Inspection Report

Basement Deficiencies/Damage

Photo 5.1- Black mold observed in basement drywall material from water infiltration.

5.2- All contaminated basement drywall must be removed and replaced at the time of remediation.

5.3- Note water stain on concrete floor at the grade intersection.

6.2- Second location of standing water on roof decking-recent rain prior to inspection.

6.3- Waterproofing delamination caused by improper system installation and inadequate construction details.

6.4- Waterproofing system failure over cant strip installations at roof/wall intersections.

6.5- Improper/inadequate flashing detail allowing to breach system at roof/vertical wall intersection(s).

6.6- Roof/wall flashing improperly installed and allowing water to penetrate under flashing details.

CONCLUSION:

The purpose of this investigation was to determine the source of extensive water infiltration andextent of subsequent damage as requested by the client. This home was completed in 2007 andbuilt by Carolina Concrete Homes, Inc. Typically, one may expect the framing system to bewood with a sheathing on the outside to attach the siding. However, ICF (insulated concreteform) construction was employed on the subject structure. Concrete is poured into a cavitybetween two layers (outside and inside) of extruded or expanded polystyrene with reinforcements.Since concrete will not "rot", this wall system is attractive for its integrity and thermal values.However, ALL wall systems must be installed in accordance with applicable building codes anddesign specifications in order to restrict water ingress. Our investigation revealed complete systemfailure and extensive water and termite damage as a result of improper construction.

Our pre-inspection protocol included a complete visual inspection of the entire structure, bothinterior and exterior. Visual examination of the interior revealed a number of locations wherevisible staining and damage of building materials was evident, indicating water ingress into thebuilding envelope (or shell). Testing for moisture content is accomplished with several moisturemeters, both invasive and non-invasive, which included scanning all interior walls to obtain arelative moisture content. Any indications of problem areas identified with moisture scannersare investigated further with a probe meter to ascertain a definitive moisture content. Anyreadings in wood above 20% or 1.0% in sheetrock indicate a potential problem usuallyassociated with exposure of the building material to moisture from water breaching theenvelope.

The CABO building code R703.8, section 1 which states flashing must be installed "At the top ofall exterior windows and doors in such a manner as to be leakproof" The 2003 (and latereditions) International Building Code, section 1405.2 requires that all "exterior walls shallprovide weather protection for the building". Additionally, section 1405.3.2 states that flashingand weepholes be installed at the system termination and structural floors, thus allowingincidental water infiltration to egress the wall cavity. The contractor omitted the requiredflashing detail at system terminations, floorlines, roof intersections and openings. Furthermore,NO construction sealant was applied on any of the exterior walls at intersections of dissimilarmaterials to prevent water intrusion. Consequently, water has already penetrated the exteriorand contaminated underlying building materials. Additionally, severe termite damage to boththe foam wall material and wood framing for openings was identified. The termites use thefoam as a tunneling mechanism in order to access moist wood members. The foam should notcome within 6" of grade level in order to prevent termite infestation. The contractor installedthe foam flush with grade, thus allowing bug infestation. Moreover, over fifteen (15) violationsof application standards relating to the stucco system were also detected, which all deviate from

Page 17: Inspection Report

"industry standards" and good construction practices. ALL code violations and applicationdeficiencies which were detected during this inspection have left the structure susceptible to severe water ingress and subsequent building envelope failure. Consequently, the entireexterior cladding must be removed and replaced during remediation to correct the inherentlydefective design which currently exists on the subject structure. I have compiled and included ascope of work to remediate all contaminated building materials and construction deficiencies asrequested.
