Building enclosure expertise includes all types of exterior wall systems, roofing systems, foundations and windows. Our structural engineers specialize in reinforced and prestressed concrete, steel, and timber structures; including building frames, facades, decks, bridges, towers, and tanks. Our construction management team and Certified OSHA experts provide investigation and analysis of construction administration disputes related to compliance with contract documents, differing site conditions, schedule and delay analysis, and jobsite safety related accidents.
Packer/ITC Experts investigates and identifies causal deficiencies attributed to design, construction, deferred maintenance, and/or owner operation that lead to problems of structural and building related distress, water intrusion, mold and rot, and costly damages. Packer/ITC Experts investigations are thorough and based on scientific methods that utilize document review, visual inspection, invasive openings, field testing, material property evaluations, and codes and standards assessments. When necessary, laboratory testing of construction elements is utilized. Testing, whether in the laboratory or the field, is performed under realistic and representative service conditions.

Windows and Curtain Walls
Building fenestration (windows, window wall, and metal/glass curtain wall systems) provides vision glass, venting, and often ventilation louvers. Windows and curtain walls are integrated with adjacent wall and roof systems, air barriers, water-resistant barriers, vapor retarders, flashing, and sealants to resist water and air infiltration. Packer/ITC Experts has a thorough knowledge of these systems and the investigation skills and experience to evaluate non-performance issues.

Hurricanes and Other Large Loss Events
Our team of construction professionals, building scientists, and engineers provide the insurance community and their attorneys with investigation and evaluation assistance on property loss claims. We investigate commercial, industrial, institutional, and residential properties damaged by wind, water/flooding, hail, and fire. We have extensive experience with investigating and identifying markers indicating pre-existing damage after sudden weather events such as hurricanes. We can assist adjusters with both emergency site mobilizations to help with their evaluation process or post hurricane evaluation of claims during or after the repair/remediation process. Our team of construction management professionals provides evaluation of Builder’s Risk Claims following catastrophic events such as wind, flooding, and fire. Property damage can be evaluated. The existing Schedule of Values at the time of the event can be established. Impact of delays on schedule and costs can be quantified.
Our collaborative team of environmental professionals and certified industrial hygienists provides environmental assessments after catastrophic events involving water infiltration and flooding that may lead to mold, bacteria, and other microorganisms in the air, water, and/or ventilation system. When an Indoor Environmental Quality (IEQ) evaluation reveals active or potential indoor air or water pollutants, we can conduct subsequent sampling and analysis to identify and quantify the pollutant. We also can analyze scopes of work by others to identify potential excessive scopes of work and associated expenditures.
Our team of fire investigation professionals has extensive experience in the determination of the cause and origin of fires and explosions in any environment. These include, but not limited to industrial manufacturing, chemical/petroleum facilities, commercial and residential buildings. We have the expertise to address fires stemming from fuel gas distribution or equipment failures, electrical system failures and/or lightning. Investigations include evaluation of the pre-storm conditions, potential code violations, equipment or piping failures, or failures in storm preparation that may have contributed to the loss.
Environmental Health and Safety
Our company and our collaborative have conducted microbial investigations at hundreds of industrial, institutional, health care, office buildings, and single- and multi-family residences over the years. Our preliminary evaluations concentrate on visual inspections and assessments to determine the source of moisture ingress, impacted materials, the presence of resultant visible fungal growth, as well as providing a wide variety of proactive IEQ services.
We generally begin a building diagnostic evaluation by reviewing the ventilation system design and operating procedures (also see Mechanical, Electrical, and Plumbing (MEP)). We also obtain direct-reading measurements of temperature and relative humidity, and indoor air contaminants such as respirable particulate and carbon monoxide. Diagnostic evaluation includes relative pressurization checks and air movement checks (also see Field Testing and Building Monitoring). Heating, ventilating, and air-conditioning (HVAC) system deficiencies are many times associated with IEQ problems. These deficiencies can occur in the design, installation, maintenance and operation of the HVAC systems.
When an IEQ evaluation reveals active or potential indoor air pollutant sources, we can conduct subsequent air sampling and analysis to identify and quantify the indoor air pollutant. Our team of skilled professionals can evaluate additional stressors contributing to IEQ complaints, such as noise, ergonomics and lighting levels.
When appropriate, we carefully design sampling regimens targeted to address a specific hypothesis. Sampling is conducted following the principles of nationally recognized guidance documents including those published by the ACGIH, AIHA, and WHO. We can sample for bacteria, fungi, and other microorganisms in air and in source (bulk) samples. We work with our clients to educate them about the usefulness and limitations of microbial sampling. We then, if needed, design sampling protocols that meets the clients’ needs.

Trips, Slips, and Falls
Probably the most common type of premises liability injuries are slips or trips leading to a fall. A thorough understanding of human gait dynamics/mechanics, tribology, anatomy and physiology, and perceptual and aging processes allows the skilled Human Factors professional to evaluate such accidents and to determine whether they could or even be likely to have occurred as described.Good examples of this would be such issues as:
- Is a walking surface sufficiently slip resistant under normal (or even abnormal) conditions to make a slip and fall unlikely, absent other contributing factors?
- Are lighting conditions or other environmental/perceptual factors such as to make it difficult for pedestrians to detect and avoid potential obstacles or unusual conditions?
- Are particular environmental or structural considerations such that they could potentially lead to a trip and fall regardless of whether or not they may meet building codes and standards?
