KELLCO is your FEDERAL, Small Business and Woman-Owned Business Advantage

Over 90% of our business is from repeat clients and referrals.

We like to think of ourselves as "The User Friendly Consultant!"





We design our inspections to fit the immediate needs of our client, and also provide the basis of an audit trail for the building. The scope of the inspection may be as broad or as limited as the building owner desires; many factors influence the type of inspection performed, including:

  • The purpose of the inspection. Finding out whether a floor tiles is asbestos containing prior to renovation is different from having a complete inspection before the sale of the building.
  • The building itself including the age of the building, the type of construction, the presence of fire proofing material; homogeneity of material throughout the building.
  • Whether the client is interested in all potential materials or specific materials (i.e., spray on ceiling, floor tiles, mechanical systems).
  • Whether the inspection is limited to materials inside the building, or if it also encompasses the roof, mechanical systems on the roof and other outside construction.
  • Whether the inspection is pre-demolition or pre-renovation (The USEPA considers demolition as disturbance to a load-bearing wall).
    Whether the sampling will be performed destructively or non-destructively; if the inspector is expected to find pipes and materials hidden within or behind walls, ceilings or floors.
  • Whether or not the inspection must meet or comply with AHERA or ASHARA requirements for schools, public and commercial buildings, or perhaps HUD standards for lead based paint in public housing.


KELLCO's inspection report will provide you with sufficient documentation to determine:

  • What was inspected
  • What was sampled
  • What materials are asbestos or leaded paint containing
  • How was the determination of hazard was made

Whenever possible we provide photographs so our client will have a visual reference of the material that is discussed.

In most cases we are able to give you floor plans that show where samples were taken.

You will always get full laboratory reports including positive and negative sample results. These can be used for reference in the future to determine if a particular material has already been sampled. Database reports are included in the report package.

KELLCO's inspection reports are written in clear and concise language so they can be read and understood by interested parties who are perhaps not fully familiar with asbestos and/or lead paint hazards.


Design of a specification depends upon many factors, including:

  • Location of the hazards in the building
  • Accessibility of the hazards
  • Will be occupied during removal
  • Probable placement of the removal containments and work areas
  • Where the HEPA fans will be situated
  • How and where supplies will be transported into the building
  • How waste will be handled, etc.

These are all in addition to the normal asbestos and lead paint related "rules and regulations" which one expects to find in a specification.

Abatement design needs also vary. Through our experience working with public and private agencies, we find that, generally, public agencies, which are required to accept the lowest bid regardless of probable work quality, need to have a great deal of specific instruction for the contractor to follow. While this increases the cost of removal, it does ensure the public agency recourse if inferior supplies and equipment are employed.

Private institutions have the luxury of pre-qualifying their contractors before offering an opportunity to bid. In our experience it is best in this case to put a little less specific detail into the specification and work with the contractor in the interest of saving the client both time and money without sacrificing efficiency or quality.


When showing the contractors the removal site for the purpose of their bids, it is helpful and advisable for the design team (thats us!) to accompany the contractors, answer questions and resolve issues that arise.


During an abatement project the building owner may decide that it is in his interest to retain an independent third party to oversee the project. This includes responsibilities such as reviewing the contractor's submittal documents, inspecting the work area at the beginning of each phase of the removal and during the work, air monitoring outside the work area during all phases of the work, providing visual and tactile inspections after removal and prior to final clearance monitoring, evaluating clearance monitoring results.

Full abatement oversight offers the security that each step of the project is completed according to the specification. The building owner can be confident that qualified professionals are overseeing the work quality and tackling complications before they become serious problems.


Before the set up of any abatement or remedial work, the air should be sampled to determine the ambient airborne fiber concentration.

After work is completed, additional samples are taken in the same area(s), and the two sets are compared. We expect the post abatement samples to be at least as clean, if not cleaner, than the samples that were taken before remedial work.


A well designed and executed abatement project will keep contaminants inside the designated work area by use of properly fitted portals. Each of these openings in the work area barrier system has a slight potential to release contaminants to the outside environment. Sampling outside each entrance and exit to the work area during abatement verifies continuation of "clean air" outside the work area.


Because of the attention to detail necessary for a successful abatement project, after the contractor completes the work it is helpful to have an unbiased third party review the work for thoroughness. KELLCO performs a visual-tactile inspection process that helps the contractor identify and rectify any details in the cleaning which may have been overlooked. Together the contractor and the consultant assess the work area a final time before clearance air monitoring begins.


Post abatement clearance sampling is used to verify that a work area has been restored to a "clean" condition by whatever standards are being applied. This can vary depending upon the type of work performed and the agreement between the Building Owner and the Contractor.


Post abatement monitoring compares the fiber concentrations inside the work area with airborne fiber concentrations inside the work area before any abatement was initiated and the standard of "cleanliness" which the contractor agreed to meet prior to the start of the project. The method of taking the samples and the type of analysis used depends upon the agreement between the Contractor, Building Owner and the Consultant.


After a leaded paint abatement on the interior of the building, dust samples are used to verify the absence of lead. The contractor is released from each Work Area when all dust wipe samples from the area are below the following levels, which are based on the HUD guidelines:

Floors 40 mg/ft²
Window Horizontal Interiors 250 mg/ft²
Window Horizontal Exteriors 400 mg/ft²


After mold has been removed from a location, post remediation air sampling is performed to document that mold spores are within acceptable air quality standards.


At the end of the project you should have one package that provides documentation of what was done, by whom, and that your facility was safe for re-occupancy. If air samples were taken, there might be some discussion of the results, particularly if corrective action was necessary. This report should become part of the permanent record of the building, and will prove a valuable aid in compliance with regulations. To the extent that KELLCO is consulting or is otherwise involved in your project, we will organize all the documentation in such a way to provide a permanent record. A CIH review, if desired, can be provided.
