Asbestos Inspections/ Surveys
In the State of Texas, public and commercial properties are required to have an asbestos inspection / survey prior to performing a renovation or demolition project. All of Precision’s Inspectors are licensed by the Texas Department of State Health Services and final reports meet all city and state requirements.
The sampling strategy Precision employs is in general accordance with Texas Asbestos Health Protection Act (TAHPA) Texas Civil Statutes Article 4477-3a, as amended, and EPA AHERA sampling protocol.
As required by the State, a minimum of three (3) samples will be collected of each identified suspect material (i.e. anything that is not wood, metal or glass). Our inspectors are trained to be as discreet as possible in sampling as to not disturb on going business. The samples are analyzed using Polarized Light Microscopy (PLM) in conjunction with dispersion staining techniques by a lab that is NVLAP certified and Department of State Health Services licensed.
If the sampled material is found to contain greater then 1% asbestos, then it is considered a regulated material.
Asbestos Abatement Consulting & Air Monitoring
If asbestos containing materials (anything containing above 1% asbestos) will be disturbed by renovation or demolition activities in a public of commercial building, then the State of Texas requires the materials to be removed by a licensed asbestos abatement contractor. Precision will work with your chosen abatement contractor and develop project specifications for the contractor to follow during remediation. Precision will also provide a licensed asbestos abatement air monitoring technician / project manager for project oversight.
Mold & Indoor Air Quality Services
Mold Assessment / Inspections
Precision will perform a preliminary indoor air-quality assessment / mold assessment to identify potential indoor air quality issues within the building or residence. The assessment will be performed by a TDLR licensed Mold Assessment Consultant.
The first step of the assessment will be to visually assess the area for visible mold and moisture. If necessary, Precision will collect surface samples and/ or non-viable air samples (i.e. spore-trap samples) for laboratory analysis. The samples will be analyzed for the presence of viable and non-viable fungal spores and structures.
Precision’s assessment will be performed in general accordance with the Texas Mold Assessment Rules and indoor air quality standards. Precision’s standard used to judge the quality of indoor air with regard to airborne fungal spores is:
A total fungal spore count of no more than 30 percent to 50 percent of outside air; and (2) Similar general of fungal spores identified inside and outside.
Also considered is the presence of a specific detrimental genre or species of fungal spores in the indoor air that are considered to be problematic in the absence of the same spores identified in outside air.
If mold remediation is needed, Precision will prepare a Mold Remediation Protocol based on the observations and assessment made by the mold assessment consultant. This will detail the scope of the remediation project, including mold abatement procedures, extent of containment, estimated quantities of materials to be removed, and post-remediation clearance requirements. After the mold remediation, Precision will conduct post-remediation clearance sampling. Clearance sampling will include a visual inspection of the containment and air samples.
- Pre-occupancy and post-construction IAQ Sampling
Precision offers pre-occupancy and post-construction indoor air quality sampling on new construction or renovation projects. The testing procedure are performed in general accordance with Federal EPA’s “Compendium of Methods for Determination of Air Pollutants in Indoor Air”. Fixed gases are sampled using low volume SUMMA canisters that run for a minimum of four hours and up to eight hours. The samples are then analyzed by a laboratory recognized and accredited by NELAP Texas Commission of Environmental Quality. Compounds and measurements that are typically are taken during IAQ sampling are Carbon Monoxide, Carbon Dioxide, Methane, Total Volatile Organic Compounds (TVOCs), Total Particulates, Radon, Ozone, Formaldehyde and 4-Phenylcyclohexene.
Lead Based Paint Services
Lead Based Paint Inspection
Precision will provide an accredited and licensed Lead Based Paint Inspector / Risk Assessor. The inspector will visually identify suspect Lead Based Paint (LBP) inside and outside the property. Samples will be taken using an X-ray Fluorescence (XRF) analyzer or surface (paint chip, wipe) samples to identify LBP. The sampling strategy will be in general accordance with the Housing and Urban Development Guidelines for Evaluation and Control of Lead-Based Paint Hazards in Housing. Laboratory analysis will be conducted by a laboratory that is in a National Lead Laboratory Accreditation Program (NLLAP). NLLAP is a Federal EPA recognized program and the industry standard.
Phase I & II Environmental Site Assessments (ESA)
The purpose of a Phase I Assessment is to accumulate data for your use in evaluating the level of environmental risk associated with the site/property, and to identify any potential concerns which may require additional investigation. Phase I ESA scope of work are performed in general accordance with the ASTM Standard E 1527-13 for conducting environmental site assessments.
Precision’s Phase I ESA will consist primarily of the following components:
- An on-site reconnaissance of the property, including a review of adjacent properties from the subject property or public access points;
- Interviews with owners/occupants and local government officials to obtain information indicating recognized environmental conditions in connection with the property;
- A review of various records to help identify recognized environmental conditions in connection with the subject property and nearby properties;
- A request for and review of state and federal environmental agency database information as outlined in the ASTM Standard;
- Visual observance of the site for evidence of significant environmental concerns, such as stored chemicals, or polychlorinated biphenyls (PCBs); and
- Preparation of a final report which details the assessment findings and includes supporting documentation.
If warranted, recommendations will be provided for further investigation of areas of concern revealed by the Phase I ESA.
If a phase I ESA Identifies a Recognized Environmental Condition (REC), then a phase II maybe needed. The Phase II ESA scope of work will be performed in general accordance with the ASTM Standard E1903-11.
