Contractor shall provide an environmental site reconnaissance report of findings and
submit to the Contracting Officer. As part of this report, Contractor shall provide cost
estimate as well as disposal facilities approved by the Royal Commission (RC) for the

Upon approval of the report and notice to proceed (NTP), the contractor shall dispose of
all hazardous materials or waste in accordance with the applicable Unified Facilities
Guide Specifications (UFGS) and or in accordance with local laws and regulations.”
All demolition material is to be removed from the site and disposed of off base.
Contractor shall be responsible to protect all existing utilities during construction.
Work includes the removal of the existing roadway pavements and fencing in the
new tow way path.

Preparation of Demolition Plan
Prior to develop the demolition plan project site personnel's meeting has been conducted
by Gilbane with Subk and discussed the step by step procedure and Demolition
requirements per contract & EM385-1-1 Section 23.
 Gilbane project and safety team developed the Demolition plan.
 Gilbane certified industrial hygienist & corporate safety manager reviewed the
demolition plan prior to submittal to government.
 Gilbane reviewed the plan on-site with subK prior to submitting the plan.
 Gilbane submitted the Activity Hazard Analysis (AHA) with the demolition plan.

Pre-Demolition Activity
Procurement
Gilbane will co-ordinate with SubK to get all necessary safety supplies to include PPE and
additional fencing for the impacted area prior to start demo work.
In addition, Gilbane hired the third party environmental company to conduct daily air
monitoring (and analysis) while demolition and disposal activities were under way.
Training
Gilbane corporate safety manager, Mr. Jeremy Sawyer, CIH, CSP & Raghuvaran
Chakkravarthy Tech IOSH, STSC conducted a joint, 8-hour asbestos, contaminated soils
and lead awareness training through WEBEX for all personnel (including SubK) who
would be working in both the impacted and disposal areas at site.
Gilbane conducted additional on-site decontamination training based on established and
accepted decontamination procedures for both personnel and construction equipment.

Pre-Demolition Activity (Cont.)
Coordination
Gilbane coordinated with RSAF and USAF and established allowable haul routes from
the site of impacted demolition to the approved point of disposal on base.
Meeting
Gilbane conducted a safety meeting with SubK to review the previous
awareness training and specific activity the hazard analysis related to these activities.
Gilbane reviewed the demolition plan and AHA with SubK prior to start work.
Gilbane and SubK conducted a preparatory meeting to cover all necessary
requirements and review the AHA related to this definable feature of work.

Pre-Demolition Activity (Cont.)
Testing & Decontamination Protocols
Gilbane safety/CIH established the testing and decontamination protocols to include method
statements, forms, logs and reporting functions for site management team.
Air Monitoring
Gilbane hired a third party environmental company to perform personal air
monitoring of site personnel and area monitoring at the demolition site perimeter
(upwind and downwind) to ensure that air quality standards and the health and safety
of all base and construction personnel is being properly maintained and that confirmed by
sampling.
At the conclusion of each day, air monitoring samples were analyzed by certified
technician to ensure compliance with standards. In the event results were outside of
accepted parameters, the field demolition method would be modified in order to meet
established air quality criteria.

Challenges
› Working with differing nationality and cultures
› Communication concerns
› Manpower issues
› Visa & Badging

Recordkeeping
› Maintaining all the training records
› Maintaining all the approved plans i.e. Demolition Plan etc.
› Maintaining the hauling demolition & debris record which
includes the date, time, truck details and volume of the material
› Air monitoring test results
› Disposal of Impacted Materials
Reference: EM385-1-1 & OSHA

Training
Translators were used on this
classroom training to ensure
everyone understands the
demolition safety requirements.
Gilbane conducted additional on-site
decontamination training based on the
approved protocols (decontamination
procedures) for both personnel and
construction equipment.

Recordkeeping
Maintained the hauling demolition &
debris record on-site including the date,
time, truck details and volume of the
material.
Trucks exiting the site through the
demolition site, gate personnel
conducted an inspection of the truck,
recorded the truck number and time of
exit. This was the daily reporting
requirement for demolition disposal.

Air monitoring test result
Each day, air monitoring samples were
analyzed against existing standards to
ensure compliance.
Goal − Minimize Your Exposure
US Government Exposure Limits:
› Time Weighted Average =
0.1 fibers/cubic centimeter of
air in 8 Hours
› Excursion Limit =
1.0 fiber/cubic centimeter in
a 30 minute period

Final Air monitoring report
Final air monitoring
reports provided the air
monitoring test results,
and a conclusive summary
from the environmental
subcontractor, Exova,
which states that “for all
work carried out on-site,
removal was done in a
safe manner and caused
no elevated levels of
asbestos dust.” Air
monitoring was
performed at demolition
sites, at the disposal site,
on personnel, and along
the haul route.

Demolition of Structures
For all demolition of impacted structures, Gilbane implemented a “wet”
demolition method. All structures to be demolished were misted with water to
ensure no dust is created during this activity.

Demolition of Impacted Structures (Cont.)
Wet Methods (water spray)
Stand upwind
(Ground personnel)
so particulates do not
blow towards worker
For all demolition of
impacted structures,
Gilbane implemented a
“wet” demolition method.
All structures to be
demolished were sprayed
with water to ensure
minimum dust was
created during this
activity.

Personal Protective Equipment (PPE)
Complete compliance with personal protective equipment (PPE) during demo work as
per approved plan and AHA.
Gilbane implemented a strictly enforced ban on cutting and grinding of impacted
structures to ensure potentially hazardous materials cannot become a health hazard to
field personnel.
Respirators (FFP3), Type 5 and Type 6
disposable coveralls, nitrile gloves &
boot covers

Demolition Area fencing and safety signs
The area surrounding the demolition site was fenced (perimeter chain link
fence was not pictured) to ensure access control to work areas. Warning signs
were placed in conspicuous locations to ensure all personnel are aware of the
dangers and remain clear of the area.

Dumping area
When trucks carrying impacted materials arrive at the gate, the gate operator
inspected the load; logged the truck number and entry time. The log was
included as part of the daily reporting function for this feature of work.

Dumping area (Cont.)
Upon arrival to the disposal site, the truck tarp was removed and directed to the
dump site by the ground guide. The impacted materials was rewetted as necessary
prior to dumping. Properly wetted debris was consolidated and compacted with
heavy equipment once dumped; site staff ensured no visible dust was generated
from the compaction of debris.

Decontamination Methodology
Daily − Thorough decontamination of haul trucks after dumping materials and prior to
leaving the disposal site. After the truck is unloaded, any excess debris was removed
from the tailgate and exterior of the truck by the disposal area hose operator.
Using appropriate PPE

Decontamination Methodology (Cont.)
At the conclusion of
disposal activities plastic
sheeting was placed over
the debris and two feet of
clean fill will be deposited
on top. The disposal area
was then graded to ensure
proper drainage.

Final Topography Survey
Final topography survey shows positive drainage from
North to South in the Containment Area.

Disposal Area
Daily maintenance and final securing of the fenced-in disposal area for impacted
materials. This effort included nightly covering of disposed materials with
polyethylene sheets, final capping of impacted materials with 1 m of soil, and
proper surface grading to ensure drainage. The completed disposal site includes a
1.7-meter-tall chain link fence, with warning signs and a locked access gate.
Six-foot chain-link fence

Final Report
Final - Training for the removal work
and Disposal of Impacted Materials
report (#120 pages) has been
submitted to GDA which included:
› Training records for both Gilbane
and SubK personnel.
› Hauling and disposal records
› Asbestos air-monitoring results
› Final topographic survey
› Photos of demo, disposal site etc.

Thank You
“Job well done … in accordance
with safety standards.”
