1. SCOPE

The work consists of the mobilization and demobilization of the contractor's forces and equipment necessary for performing the work required under the contract. It does not include mobilization and demobilization for specific items of work for which payment is provided elsewhere in the contract. Mobilization will not be considered as work in fulfilling the contract requirements for commencement of work.

2. EQUIPMENT AND MATERIAL

Mobilization shall include all activities and associated costs for transportation of contractor's personnel, equipment, and operating supplies to the site; establishment of offices, buildings, and other necessary general facilities for the contractor's operations at the site; premiums paid for performance and payment bonds including coinsurance and reinsurance agreements as applicable; and other items specified in Section 4 of this specification.

Demobilization shall include all activities and costs for transportation of personnel, equipment, and supplies not required or included in the contract from the site; including the disassembly, removal, and site cleanup of offices, buildings, and other facilities assembled on the site specifically for this contract.

This work includes mobilization and demobilization required by the contract at the time of award. If additional mobilization and demobilization activities and costs are required during the performance of the contract as a result of changed, deleted, or added items of work for which the contractor is entitled to an adjustment in contract price, compensation for such costs will be included in the price adjustment for the item or items of work changed or added.

3. PAYMENT

Payment will be made as the work proceeds, after presentation of paid invoices or documentation of direct costs by the contractor showing specific mobilization and demobilization costs and supporting evidence of the charges of suppliers, subcontractors, and others. When the total of such payments is less than the lump sum contract price, the balance remaining will be included in the final contract payment.

SPECIFICATION

612 TREE PLANTING

1. SCOPE

This work shall consist of site preparation, furnishing, transporting, temporary storage and planting tree seedlings of the species, method and quality specified and at the locations shown in Attachment B.

2. MATERIALS

Unless otherwise specified, all plant materials used shall be true to name, size and quality in conformity with the following standards:

AMERICAN STANDARD FOR NURSERY STOCK. Copyright 1973 (current edition

2004). ANSI Z60.1 - 2004 (Published by the American Association of Nurserymen, Inc., 230 Southern Building, Washington, DC 20005)

a. Verification of Sources of Supply.

The contractor shall verify, prior to bidding, all sources of supply to ensure all plant materials, of size, species, variety, and quality noted and specified, can be supplied.

b. General Requirements.

A minimum of 2% of the plants of each type representative of the planting group in a

Tract will be properly identified by species name and size on legible weatherproof labels securely attached to the plants.

All plants shall be nursery grown from a seed source collected within a 300-mile radius of the job site and from an appropriate bottomland or upland source, as the case shall be, for the given species selected.

All plants shall have normal, well-developed branches and vigorous root systems characteristic of the species. They shall be sound, healthy, vigorous, free from defects, disfiguring knots, abrasions of the bark, sun scaled injuries, plant diseases, insect eggs, borers, and all other forms of infections. They shall be carefully dug such that the major portion of the root system, including the fibrous roots, remains intact. The soil shall be carefully removed from the roots, avoiding unnecessary loss or breakage of fibrous roots.

Any roots that are broken or which must be cut shall be cleanly cut. The roots of all plants shall be protected at all times to prevent injury or drying caused by heat, sun, wind, and freezing temperatures.

All plants shall be dormant when collected.

WRE Tree Planting 612-2 - 2 -

Plants which have been held in storage shall be rejected if they show signs of growth during storage.

c. Inspection of Plant Material.

The Contractor shall notify the Technical Point of Contact at least one (1) week prior to delivery. The Technical Point of Contact will have the option, at their discretion, to inspect the plants for acceptance at the place of growth. Inspection at the place of growth will not impede the right to reject plants at the planting site.

The Contractor shall notify the Technical Point of Contact when the plant materials arrive upon the job site. Plant materials shall be inspected, and a determination shall be documented as to their condition relative to their suitability for planting prior to the commencement of work.

Final acceptance of all plant materials shall be given only after the materials are planted and after all requirements are met. Unacceptable plant material shall be immediately removed at contractor’s expense from the jobsite.

d. Delivery and Storage.

All plants shall be packed in such a manner as to insure adequate protection against climatic, seasonal or other injuries during transit. Special care shall be taken for prompt delivery and careful handling in loading and unloading. Plants should be kept moist during transportation, storage, and during the planting operation. Seedlings should be planted within five (5) days of arriving at the site. If the tree seedlings are not planted within five (5) days after they have arrived from the designated nursery, the Contractor shall place them in cold storage at 35 to 45 degrees Fahrenheit. The Contractor shall be responsible for protecting the seedlings from injury or theft during the contract period.

No plant shall be pruned prior to delivery. Root stock may be pruned at the planting site, to a length no less than 8 inches, to accommodate the proper placement and position of roots in the planting trench.

Each shipment of plants to the site shall be accompanied by a delivery slip indicating source of supply, exact quantities, sizes, and species delivered. A copy of all delivery slips shall be delivered to the Technical Point of Contact.

e. Measurement for Size

All planting stock shall be bare root seedlings, nursery grown for a minimum of one year.

The minimum height of seedling stock shall be 12 inches, measured from the root collar to the tip of the branches. The minimum seedling diameter shall be 7/32 inch, measured at 1 inch above the root collar. The minimum length of roots shall be 8 inches, measured from the root collar to the tip of the roots. All seedlings shall have at least 5 primary roots 1/10-inch diameter or larger. Roots longer than 8 inches may be pruned to 8 inches

WRE Tree Planting 612-3 - 3 -during the same day in which they will be planted, to accommodate proper placement in the planting trench.

3. SITE PREPARATION

Site preparation will be required to be performed on the entire acreage of the tree planting area prior to tree planting. The only approved method of site preparation shall be rotary mowing.

The existing vegetation shall be mowed to a height no greater than 8 inches above the ground.

Disking or strip mowing is not authorized.

4. PLANTING

a. Planting Procedures

(1) Seedlings shall be planted upright with no more than a 20% lean. Soil shall be packed firmly around seedling roots to eliminate air pockets. Furrows shall be sufficiently pressed to ensure that seedlings will not be windthrown or scoured out during flood flows. The

Contractor shall ensure that planting furrows are deep and wide enough to fully extend roots.

Tree seedlings shall be planted so that the root collar is placed 1/2 inch deeper than the depth at which it was grown in the nursery. Trees shall be planted with conventional forestry planting equipment such as the dibble bar, planting spade, or mechanical tree setter.

(2) Seedlings shall be planted on the geographic contour. The Contractor shall plant the species type and number identified in the planting groups contained in this specification, at the locations identified for the appropriate planting group on the maps provided in Attachment B. To attain a random species, mix within the planting group, the Contractor shall ensure that at least two species are planted per row and that no two rows of the same species are planted adjacent to one another.

b. Inspection Requirements

Inspection of seedling quality by the government or its agents will be performed under this contract prior to or at the beginning of the planting of the seedlings. The government or its agents shall be given at least 48 hours’ notice of the anticipated arrival of seedlings and planting crew to each site to facilitate the completion of this inspection requirement.

Inspection by the government of the tree planting adherence to contract specifications will be performed under this contract by measuring sampling plots. A sampling plot is defined as a 1/20-acre sample taken for every 10 acres of planted area. An area will be considered adequately planted when a minimum of 80% of the trees in each sample plot meets contract-planting specifications. In the event, a sample plot fails to meet the contract requirements, the Contractor will be required to re-work the 10-acre area prior to re-inspection. The re-inspection sample plot will not be the original sample plot.

5. MEASUREMENT AND PAYMENT

Method 1

The acreage figure for each tract or planting group is an estimate that was made on an aerial photograph.

Payment will be made to the nearest 0.1 acre. The estimated acreage will not be re-measured or adjusted further. Contractor is responsible for providing and planting the number of trees necessary to achieving the

WRE Tree Planting 612-4 - 4 -specified spacing. Such payment will constitute full compensation for furnishing, transporting, planting trees complete and in place. For items of work for which specific unit prices are established in the contract, each area treated as specified will be measured to the nearest 0.1 acre. Payment for treatment will be made at the contract unit price for the designated treatment which will constitute full compensation for completion of the work.

The payment for planting trees and shrubs shall be paid for at the contract unit price. Such payment shall constitute full compensation for all labor, tools, equipment, materials, and other necessary and incidental to completion of work.

Method 2

For items of work for which specific lump sum prices are established in the contract, the quantity of work will not be measured for payment. Payment for this item will be made at the contract lump sum price for the item and will constitute full compensation for completion of the work.

Method 3

For items of work for which lump sum prices are established in the contract, payment will be made as the work proceeds, after presentation of invoices by the Contractor showing related costs. If the total of such payments is less than the lump sum contract price for this item, the unpaid balance will be included in the final contract payment. Payment of the lump sum contract price will constitute full compensation for completion of the work.

All Methods

The following provisions apply to all methods of measurement and payment. Compensation for any item of work described in the contract will be included in the payment for the item of work to which it is made subsidiary. Such items and the items to which they are made subsidiary are identified in Section 6. Payment will be made by electronic transfer.
