Penta Engineering - Full Service Facilities and Remedial Design Engineering Consultants

PENTA Engineering Group, Inc. (PENTA) provides clients with a wide range of asbestos and lead consulting services. Our staff is well trained and accredited to provide these services to our clients. PENTA’s objective is to understand a facility’s condition, evaluate concerns, and develop a strategy with the owner/manager to mitigate those concerns and produce a cost-effective solution to fit Commercial, Industrial, Healthcare, and Governmental Institutions.

PENTA’s services include, but are not limited to, the following:

Asbestos Surveys – PENTA’s EPA AHERA accredited asbestos inspectors perform baseline and project specific asbestos surveys to assist building owners/managers in conforming to applicable OSHA/EPA regulations. PENTA’s accredited inspectors work closely with the client to develop a cost effect sampling strategy to document the presence or absence of asbestos in building materials.
Operations and Maintenance Program Development – PENTA can provide clients with programs to properly manage asbestos-containing materials in place. Our EPA AHERA accredited Management Planners and Project Designers can develop a workable program to assist our clients in conforming with EPA and OSHA’s asbestos regulations.
Bidding and Contract Document Development – PENTA’s EPA AHERA accredited Project Designers can develop work procedures and project specifications for asbestos abatement to assist clients in executing asbestos abatement projects. These documents may include bid forms, contract documents, design drawings, and technical specifications for abatement efforts.
Contract Administration – PENTA can assist clients in each phase of the abatement project, from design documents, bid evaluation, evaluation of applications for payments, change order requests, and close-out documentation.
Air Monitoring and Work Practice Observation Services – During asbestos abatement efforts, PENTA can provide Resident Project Representatives (RPRs) onsite to perform air monitoring adjacent active asbestos abatement work areas to document the effectiveness of the Contractor’s control measures, and clearance air sampling within the work area prior to removal of critical barriers and re-occupancy of the area. We further document the selected contractor’s compliance with contract documents and applicable Federal, State, and local regulations.

PENTA offers the following types of air sampling options for our clients:

Phase Contrast Microscopy (PCM)

PCM microscopy provides a fast turn-around to document representative airborne fiber concentrations in an area. This type of air sampling is not specific for asbestos dust, but identifies the total particulate load (asbestos fibers and other fibers).

Our RPRs have successfully completed the NIOSH 582 course and can analyze PCM air samples onsite

Transmission Electron Microscopy (TEM)

TEM microscopy is specific for asbestos fibers and is performed offsite by a NVLAP accredited, third party laboratory.

TEM clearance sampling is required by EPA AHERA in schools (Grades K through 12), the Georgia Board of Regents in State colleges and university campuses, and by certain states outside of Georgia

Contamination Assessments - PENTA’s professionals have experience in evaluating potential asbestos contamination in areas following a suspected fiber release episode. Following the evaluation, PENTA can assist clients in development and implementation of an appropriate, cost effective response action. Some of the environmental sampling performed during contamination evaluation includes the following:

Micro-vacuum dust sampling

Micro-vacuum dust sampling is performed in general accordance with ASTM D5755-95, “Standard Test Method for Microvacuum Sampling and Indirect Analysis of Dust by Transmission Electron Microscopy for Asbestos Structure Number Concentrations”.

TEM Air Sampling

TEM air sampling provides an indication of airborne concentrations of asbestos in areas following a suspected asbestos fiber release episode.

Our professional team of engineers is dedicated to meeting the needs of each individual client and can tailor a scope of services to meet those needs.
