encapsulant on a minimum 9.3 square meter 100 square feet of soil area
onsite. The test shall be witnessed by the CO and the manufacturer's
representative. A written application for encapsulation shall be submitted
to the CO with test results, encapsulant manufacturer's positive
recommendation for use, a guarantee for satisfactory performance for 10
years, and limitation of application. If the application is accepted, the
soil encapsulation shall proceed in compliance with all provisions and
instructions of the encapsulant manufacturer and under the supervision of a
person certified by the manufacturer who is trained and experienced in the
proper application of the soil encapsulant. See DETAIL SHEET 72.] [A
concrete slab of minimum [50] [_____] mm [2] [_____] inch thickness shall
be poured over the entire soil surface. Soil surface shall be thoroughly
dampened before pouring concrete. Soil encapsulators and supervisors shall
be primarily concrete workers trained to work in asbestos contaminated
environments. See DETAIL SHEET 71.]

Enclosure of ACM
**************************************************************************
NOTE: Select the applicable requirements for the
required enclosure method. Delete encapsulation
methods and materials which are not used.
**************************************************************************
Isolation of ACM by construction of a permanent enclosure shall be
conducted as specified in Section [_____]. Enclosures shall be as follows:
a.
Enclosure of Acoustical Wall Plaster on Masonry Wall:
See Detail
Sheet 37
b.
Enclosure of Asbestos Contaminated Soil:
See Detail Sheet 71
c.
Enclosure of Acoustical Ceiling Plaster, Spray-on Fireproofing and
Thermal Insulation Plaster: See Detail Sheet 43.

Encapsulation of ACM
**************************************************************************
NOTE: Remove items in this subparagraph that do not
apply.
**************************************************************************
Prior to applying any encapsulant, the entire surface area shall be
inspected for loose, or damaged asbestos material:
a.
Penetrating Encapsulation: Before penetrating encapsulation is
applied, asbestos removal work in the area shall be complete.
Substrate shall be evaluated before application to ensure that the
encapsulant will not cause the substrate to fail in any way. Plug
samples shall be taken to determine if full penetration has been
achieved. If full penetration has not been achieved, surfaces
shall be recoated while the matrix is still wet, until full
penetration is achieved: See Detail Sheet 39.
b.
Bridging Encapsulation: The surface shall be encapsulated in
sections of 93 square m 1000 square feet or less as recommended by
the encapsulant manufacturer. Upon completion of each section,
the dry thickness of the bridging encapsulation shall be measured.
Additional bridging encapsulant shall be applied to obtain the
