3.1 PROTECTION INSTALLATION

A. Provide temporary work limit fencing, tree trunk wrap, and tree barricades to protect existing trees, plants and critical root zones as directed by the Contracting Officer. Protections shall be in place before any excavation work or heavy equipment is allowed on site.

3.2 CONSTRUCTION FENCING

A. Within the perimeter work limits, protect groups of shrubs and small trees and undisturbed soils as directed by the Contracting Officer with construction fencing. Firmly anchor fences to the ground a minimum of 2 feet from the nearest plant. Completely and continuously enclose areas of trees and shrubs to be protected with fencing.

3.3 TREE TRUNK PROTECTION

A. For isolated trees up to 4 feet dbh (diameter breast height) within the work limits, provide tree trunk protection as directed by the Contracting Officer.

B. Wrap wood lathe snow fencing continuously around the circumference of the trunk from the base to a height of not less than 6 feet. Wrap shall be a minimum of two layers. Fence wrap shall be secured around the trunk by three strands of jute or other natural fiber rope around top, middle and bottom of the tree trunk protection. No anchoring or nailing in trees will be allowed.

3.4 PROTECTION MAINTENANCE

A. Only after all tree and plant protection has been installed, and the Contracting Officer has inspected and given written approval of the tree and plant protection, will the Contractor be allowed to begin excavation. All tree and plant protection shall be maintained throughout the duration of this project.

B. If any fencing, barriers, staking or marking, which designates protected areas, limits of demolition or work limits, is knocked down, moved or destroyed by the Contractor, the Contractor will immediately move the work operation to another area, wholly or in part, or suspend work operations, until the fence or other protection is repaired to the Contracting Officer's satisfaction at the Contractor's expense. Time lost due to such stoppage will not be considered basis for adjustment of completion date nor additional payment.

C. Parking vehicles and storing materials or supplies shall be confined to areas designated as staging areas on the plans or as specifically approved by Contracting Officer. Vehicle and material storage activities are strictly prohibited from protected and fenced sensitive soil and vegetation areas.

D. Fastening ropes, cables, or guys to existing trees and disposing of materials including, but not limited to paint, paint thinner, fiberglass materials, fiberglass thinners, concrete or cement residue, washings from cement or concrete mixers or any other material considered harmful by the Contracting Officer is prohibited anywhere in the project area.

DEPO – 230327 01 12 00 - 3

E. Do not remove, injure, or destroy trees or other plants without prior approval of the Contracting Officer. Consult with the Contracting Officer and remove agreed upon roots and branches that interfere with excavation or pipe placement. All pruning of canopy or cutting of roots will be done under the supervision of the Contracting Officer, and shall be done as set forth by the National Arborist Association or the International Society of Arboriculture.

F. If directed by the CO, excavate with hand tools.

G. At project completion, the Contractor shall remove all protections and be properly disposed of or recycled.

3.5 PLANT APPRAISAL

A. If the Contractor destroys or injures trees and shrubs designated for protection or outside of the perimeter work limits, the Contractor will be assessed damages prior to final progress payment.

B. Replacement costs for damaged vegetation will be computed according to the method described in the International Society of Arboriculture's 1992 Guide for Plant Appraisal. This method is based on the cost of the largest commonly available tree or shrub, with modifications based on species value, condition and location. A trained arborist or professional plant appraiser from the California region will be hired by the Contractor to make the damage appraisal. The arborist's fees will be included in the damage assessment. The damage assessment will be done as the damage occurs.

C. The damage appraisal process will be triggered by any of the following types of damage to vegetation outside of the perimeter work limits or fenced or otherwise protected areas of soil or vegetation within the perimeter work limits:

1. Removal of any tree or shrub designated to remain.

2. Pruning of a tree or shrub canopy without authorization from the CO.

3. Removal or fracture of lodge pole pine trees greater than 8 inches in diameter without CO authorization.

4. Trenching or soil disturbance within the critical root zone that is deeper than 6 inches without authorization from the CO.

5. If the damaged vegetation is protected under the Endangered Species Act or other special legislation, additional penalties may be assessed.

6. Pruning or removal of vegetation when authorized and supervised by the Contracting

Officer is excepted from these penalties.

D. Minor cuts and damaged areas shall be treated in accordance with tree and plant repair practices specified by the National Arborist Association, the International Society of Arboriculture, or a qualified arborist.

3.6 PLANT APPRAISAL METHOD (TRUNK FORMULA METHOD)

A. The following sample appraisal is based on the Trunk Formula Method, established by the International Society of Arboriculture, in 1992. This formula can be applied to trees and very large shrubs, or multi-stemmed trees. It is based on the size, species, condition and location of the plant that was injured or destroyed.

DEPO – 230327 01 12 00 - 4

1. Size: For the purpose of appraisal, size is determined by the area of trunk, usually at breast height (or 4.5 feet), calculated by diameter or circumference measurement. Example for a 24" diameter trunk: 24" divided by 2 = 12" radius, X = 3.14, Xr²= area of a circle, 3.14(12²) = 452"

2. Modifications to measuring technique will occur in the case of multi-stemmed trees, trees with major branches lower than breast height, etc.

3. Species: A rating is given for each species, depending on the region in which it is living.

The International Society of Arboriculture has a number of regional chapters that have generated species rating lists. Ratings are based on some of the following factors: climate adaptability, growth characteristics, soil adaptability, resistance to disease and insects, maintenance requirements, aesthetic and general functional values, and rarity.

4. Condition: A rating is given for the general condition of the plant which involves health and structural integrity. See the "Guide to Judging Plant Condition", following.

5. Location: A rating is given for the location of the plant and includes site, placement, and functional and aesthetic contributions.

B. The Trunk Formula Method is based on the following equation:

Appraised Value = Basic Value x Condition x Location Basic Value = Replacement Cost + (Basic Price x [TAA - TAR]) x Species

1. Replacement Cost = maximum size commonly available from local or regional nurseries, usually around 4" diameter. The cost includes the average cost (from 3 nurseries, min.), transportation and installation, guarantee and profit.

2. Basic Price = cost per unit of trunk area of replacement tree (cost may be wholesale, retail, or installed).

3. TAA = Trunk area at breast height of tree being appraised.

4. TAR = Trunk area at 12" from base of largest commonly available tree.

5. Species, Condition and Location = ratings of the appraised tree.

Home office overhead shall contain only allowable, allocable, and reasonable costs per the contract documents and FAR Part 31. Profit percentages are based on risk factors found in FAR Part 31which have been applied to the specific type of work included in this project.

The following percentages establish the maximum allowable markups (OH&P) for contractor self-performed work:

Overhead………………10% Profit…………………..10%

2. Total aggregate limit of markup (OH&P) for contractor and subcontractors on modification work shall not exceed twenty percent (20%). The NPS will not be responsible for allocation of percentages between contractor and subcontractors at any tier.

3. If contractors form a partnership, than the partnership may only receive home office overhead and profit in the same amount as an individual contractor (refer to par 1.3,E,1 above). It is the responsibility of the partners to decide on the division of revenue.

4. Combined Increases and Decreases: On proposals involving both increases and decreases in the Contract Price, the overhead and profit mark-ups are required on the net increases and deducted on net decreases.

5. At no time can profit be calculated on Overhead or itself, it must be calculated on direct costs of work only.
