termites as follows:
REFERENCE STANDARDS FOR PRECONSTRUCTION
SOIL TREATMENT FOR PROTECTION
AGAINST SUBTERRANEAN TE RM ITS•~
;~Approved by National Pest Control Association, Inc.
June, 1965
Chemicals used as a soil treatment to establish a barrier which
is lethal or repellent to subterranean termites. The toxicant must
be applied with such thoroughness and uniformity that it provides
a barrier in all routes of termite entry. Precautions to be observed
in &ai>.dllng concentrated chemical formulations and in the application
of dlluted materials are given in the !"'Approved Reference Proce-
dures for Subterranean Termit Control" of the National Pest Con-
trol Association. Applications according to the following reference
concentrations and reference application rates will achieve a pro-
longed period of protection that is customarily guaranteed by pest
control firms.
-5-

=:~l,;==I --=--==--==·--=-==--=---=-==-=---·=· =======~

Effective soil treatment requires the dispersion in the soil of a
required amount of toxicant. Two interrelated factors are: the
amount of chemical and a means of dispersing it in the soil. These
factors are controlled by the concentration of the chemical and the
rate and uniformity of application. A balance must be maintained
between the concentration and volume applied. Neither should .be
changed without appropriate adjustment of the other.
Four termite toxicants are recognized as the most effective and
long lasting of those tested to date. These four toxicants may b1e
regarded as being equal in effectiveness and longevity when applied
at comparable dosages at their respective recommended concentra'."
tions. It is recommended that any of the four be applied as an
emulsion in water.
The toxicants and recommended reference concentrations for
each are:
Aldrin (actual
Chlordan (technical)
Dieldrin (actual
Heptachlor (actual)
0. 5% by weight
1. 0% by weight
0. 5% by weight
0. 5% by weight
Combinations of these toxicants are acceptable as long as they are
proportioned to provide the equivalent of the full reference concen-
tration. For example, one half of the reference concentration of'
one toxicant could be combined with one half of the reference con-
centration of another to provide a full reference concentration.
Reference application rates for soil toxicants are as follows:
For slab-on ground construction
(a) one gallon per 10 square feet as an overall treatment under
the slab and under attached porches.
(b) four gallons per 10 linear feet to critical areas under the
slab, such as along the inside of foundation walls and both sides
of interior partition foundation walls, or around utility services
or other features that will penetrate the slab.
(c) four gallons per 10 linear feet along the outside of the founda-
tions.
(d) two gallons per 10 linear feet in the voids of all unit masonry
foundation walls or piers.
For basement construction

(a) one gallon per 10 square feet as an overall treatment under the
basement slab.
(b) four gallons per 10 linear feet to critical areas within the base-
ment area such as abng the inside of foundations walls, along both
sides of partition foundation walls, around piers, and around the
entrance of any utility service or other feature that will penetrate
the basement slab.
(c) four gallons per 10 linear feet along the outside of foundation
walls where the foundation is of poured concrete or where the foot;-
ing for masonry foundations is 30 inches or less below grade level~
including that part that will be under platforms or porches.
Eight gallons per 10 linear feet where the footing for
masonry foundations is more than 30 inches below
grade level.
(d) two gallons per 10 linear feet in the voids of all unit masonry
foundation walls or piers.
In some cases soil will not accept liquids at the reference
rates of application. When the condition exists, a lesser
volume of carrier, with an equivalently greater concen-
tration of toxicant, may be used. For example, 5 gallons j .
of 2o/o chlordane. The actual amount of the insecticide ·
per linear or square foot of soil should not be reduced and
it must be properly distributed to provide an adequate
barrier of treated soil.
Section 2518 of the Uniform Building Code, 1970 Edition, is ·
amended by amending sub-section (a) thereof to read as follows:
'(a) General. In one and two story buildings housing groups H,
I and J Occupancies, where engineering design is not provided,
where the floor live load does not exceed 50 pounds per square
feet, and when the roof live load does not exceed 20 pounds per
square feet, span tables for joists and rafters as published by
the National Forest Products Association may be used to determine
framing requirements. The allowable span of horizontal load
bearing members shall be taken as the clear horizontal distance
between supports. '

To The Honorable Mayor and City Council
City Of Lubbock
Municipal Building
Lubbock, Texas
Gentlemen:
The City Council appointed Code Study Committee, after quite a number of meetings to
study in detail the differences between the 1964 edition and the 1970 edition of the
Unifonn Building Code submits the attached list of changes and unanimously recommends
the adoption of the 1970 editton of the Unifonn Building Code as per attached amendments.
The changes between the 1970 and the 1964 editions can be broken down into three (3)
general catagories as follows:
Catagory-1 •
Catagory-2.
A group of changes required to bring the 1970 edition into
confonnity with the Statues or Laws of the State of Texas.
These amendments were and are necessary for the 1964 and/or
1970 edition. They now exist and are required changes in
the 1970 edition as Texas has some specifics that ·are in
conflict with or are not allowed under Texas law.
All of the current and existing amendments to the 1964
edition were recommended to be carried forward to the 1970
edition. These cover such items as Signs, Moving structures,
Demolishing structures, Contractor•s bond, etc. The Committee
recommended slight up.grading of fees charged where pennits
are required. (See pennit schedule Sect. 303 of attachment)
For the most part, the changes in this catagory are basicly
editorial. There has been a strong effort to be more
specific in the wording of the 1970 edition in order to
"spell out" what is intended and therefore, leaves less to
interpretation.

Catagory-3. This catagory covers basics such as Engineering and
Safety to Life and Property. The 1970 edition recognizes
and accepts all of the latest engineering principles as
relate to latest materials that have been proven. This
includes such items as both high tensile steel and high
strength concrete. The 1970 edition accepts the complete
new lumber for what its capabilities are and allows full
use according to engineering design and requirements and
should have a strong influence on wood-frame type
construction. In the re-write of Chapter 25, which is
wood-frame construction, stud spacing is pennitted up to
twenty-four (24) inches, when properly braced, and where
loading from an engineering stand point does not exceed
certain lfmits. This and other changes in Chapter 25
should help keep the cost of homes and wood-frame apart-
ment butld'ings from rising so much due to the increase
in the cost of lumber. This is also true in commercial
structures that have wood as part of their structure.
The Fire requirements and Safety to Life and Property has
relaxed some in the Group "'C'* and Group "F 11 Occupancies
where in size, conditions and the age of the occupants is
taken into consideration. This should be a benefit to the
conmercial builder and owner.
These same Fire and Life Safety requirements have been made
slightly more restictive for Group "D" Occupancies but this
is to be expected as the occupancy includes such as Hospitals,
Nursing and Convelescent Home and sill'lllular type uses. This
is understandable particularly where taking into consideration
non-ambulatory persons-This also brings City requirements ·
more inline with State and Federal requirements, such as the
Hill-Burton Act.
Therefore, the duly appointed Code Study Committee respectively recommends that the
City Council adopt the Unifonn Buildt_ng Code, 1970 Edition with the attached
amendments.
