It is fully understood and agreed that any differential cost will be included in the price bid for other roadside development items. Payment will be made under: 219-A: Watering - per M gallons SECTION 220 - INSECT PEST CONTROL
220.01 Description . This work consists of furnishing and applying approved
insecticides to control armyworms and other destructive insects that damage or destroy planted vegetation. It shall be the Contractor's responsibility to continually observe the planted areas for insect damage, especially during the late su mmer and early fall. The Contractor shall, upon observing destructive insects, report it to the Engineer. If the Engineer or the Engineer’s representative observes insect damage, the Contractor will be notified.
220.02 Materials . The Contractor shall select a nd furnish an effective insecticide
produced by a reputable manufacturer in acco rdance with all Federal and State Laws and Regulations, and it shall meet the approval of the Engineer. The material shall be furnished in properly labeled containers.

The Department will not be liable for violations in applying the material or damage caused by its use.
220.03 Construction Requirements .
220.03.1 General . The Engineer will determine the areas to be treated, and the
Contractor shall immediately treat these ar eas unless weather conditions are unfavorable for proper treatment. The Cont ractor shall apply the approved insecticide at the rate and in the manner according to the requirements shown on the labe l of the container for the destructive pest being controlled. The equipment used in applying the material shall produce uniform coverage. The Engineer will determine if satisfactory pest control was obtained on the treated areas. The Contractor shall reapply insecticides to areas where control is unsatisfactory at no additional cost to the State. When the Engineer determines that pest control efforts were timely and correctly applied, the Contractor will be paid for any required re-g rassing. If the Engineer determines that pest control efforts were unsatisfactory, th e Contractor will re-grass the area at no additional cost to the State.
220.03.2 Safeguards . In addition to the requirements specified in Subsection 220.02,
safeguards in applying insecticides are th e responsibility of the Contractor, and the Contractor shall be responsible for damage to the wildlife and human welfare. The following are minimum basic safeguards to be observed:
a.All insecticides shall be applied by approved ground equipment or approved aircraft mounted spray equipment. Aerial application shall be approved in writing by the Engineer.
b.Personnel must be qualified to engage in this work.
c.Personnel handling the insecticide and equipment operators must wear the recommended protective apparel.
d.Avoid drift of insecticide on adjacent property. (e) Do not contaminate streams, ponds or lakes.
f.Some insecticides are high ly toxic to bees. When application is to be near bee hives, provide a day advance notice to the beekeeper.
g.Normally, insecticide application will be restricted to roadside areas that are under construction and not open to the public. Precautions for the protection of the public must be taken when treatment is ordered for rest areas, parks, etc.; namely, by keeping pedestrians off the area until the insecticide is washed off the turf area or the insecticide deteriorates and is not harmful. Application methods and rates shall be in accordance with the instructions shown on the label of the insecticide container.
220.03.3 Contract Quantities . The quantity for insect pest control is estimated for
bidding purposes only and this quantity may be varied dependent upon actual need or omitted entirely.
220.04 Method of Measurement . Insect pest control of the area properly treated and
accepted will be measured by the acre. The area shall be computed from measurements taken parallel to the surface of the treated area.
220.05 Basis of Payment . Insect pest control, measured as provided above, will be paid
for at the fixed contract unit price per acre as pre-entered in the proposal and shall be full compensation for co mpleting the work. No change in payment will be made because of differential costs from the fixed contract unit price. It is fully understood and agreed that any differential cost will be included in the prices bid for other roadside development items. Payment will be made under: 220-A: Insect Pest Control - per acre Section 221 Section 221 SECTION 221 - PAVED DITCHES
221.01 Description . This work consists of constructing paved ditches of hydraulic
cement concrete or hot bituminous plant mix, as specified in the contract and constructed in accordance with th e provisions and requirements of these specifications, and in reasonably close conformity w ith the lines, grades, typical cross sections, and locations shown on the plans or established.
221.02 Materials .
221.02.1 Concrete Paved Ditches . The materials used in the construction of cement
concrete paved ditches shall conform to the applicable provisions and requirements of Section 804.
221.02.2 Bituminous Paved Ditches . The materials used in the construction of
bituminous paved ditches shall conform to the applicable requirements for hot bituminous mixtures as set out in Section 401.
221.02.3 Reinforcement . Reinforcement shall meet the requirements of Subsection
711.02 221.03--Construction Requirements .
221.03.1 General . The foundation for paved ditches shall be formed by excavating to
the required depth and dimensions below the prepared finished surface grade of the paved ditch. The foundation shall be thoroughly compacted by hand tamping or other approved method. Soft, spongy, or other unsuitable material shall be removed as directed and replaced with suitable material thoroughly compacted in six inch layers. The forms used in this construction may be wood or metal; shall have a depth equal to the prescribed edge thickness of the paved ditch; and shall be of sufficient strength to withstand the weight of the concrete or bituminous mixture and the pressure incidental to vibration or compaction without bulging or displacement. Form s shall be securely staked and braced. Reinforcement, if specified, shall be placed in a manner that will ensure its proper position in the paved ditch section after all concrete is placed.
221.03.2 Concrete Paved Ditches . Unless otherwise specified on the plans, the
concrete paved ditches shall be constructed of Class "C" concrete, mixed and placed in accordance with the applicable requirements of Section 804, and cured in accordance with the requirements of Subsection 501.03.20 or by other approved methods. The limitations of mixing and placing shall conform to the requirements of Subsection
501.03 12.
A template mounted on the side forms shall be used in striking off and finishing the surface of the concrete to th e required shape and dimensi ons. The entire unit shall be constructed monolithic with smooth fillets or curves at all angles or breaks in flow lines. Concrete shall be placed beginning at the bottom of the slope and progressing upward.
