SECTION C - DESCRIPTION/SPECIFICATIONS/WORK STATEMENT

Titan Trail Bridge Construction Ketchikan Misty Ranger District, Tongass National Forest

C.1 Project Description and Location

a) Description: The work is the construction of a 90 ft long x 5 ft wide trail bridge over Fish Creek on the Titan Trail at MP 0.13. Work includes designing, fabricating, transporting, and constructing a trail bridge superstructure and substructure.

Bridge superstructure components to be mostly above the deck. For example steel pony truss or timber tied arch

Work also includes reconstructing approximately 700 feet of gravel trail from the Titan Trailhead Parking Area to the bridge site, which includes 30 feet of elevated boardwalk across an overflow channel; constructing 72 feet of new gravel trail and a set of steps to the bridge; and constructing 97 feet of elevated boardwalk trail with railing from the bridge to the existing trail on the far side of the creek.

b) Location: The project is located just off the Salmon River Road approx. 3 miles from Hyder, Alaska. Hyder is accessible from the Canadian highway stystem through Stewart, British Columbia. Hyder is also accessible by float plane, barge, and boat from Ketchikan, Alaska. Ketchikan, Alaska, and Terrace, British Columbia, are the nearest full service cities.

The Titan Trailhead Parking area is on the east side of the Salmon River Road just past the Fish Creek Wildlife Observation Site. The bridge site is approximately 700 feet from the parking area.

c) There are no utilities available at the project site.

d) The use of equipment and power tools will be allowed. Tracked and wheeled construction equipment may access the bridge site along the existing Titan Trail. Wheel base of equipment to be less than 5 feet. This portion of the Titan Trail will be reconstructed to 3 feet finish width. The Contractor may place minimal gravel in the trailway, outside the tread width, to accommodate equipment up to 5 feet wide. This gravel will be removed and/or incorporated in the finished trail at the end of the project.

e) The use of helicopters and power tools in the project area is allowed.

f) Fish Timing. Work in the wetted perimeter of Fish Creek is allowed between June 1 and June 30 only.

g) Price Range: Between $250,000 to $500,000.

C-2 Geotechnical Investigation A geotechnical investigation was conducted on the west (highway) side of Fish Creek near the proposed abutment. A small backhoe excavated a test pit. The findings were a layer of organic material and duff for approximately the top two feet, then gravelly sand. Similar conditions exist on the east (trail) side of the creek, however the depth of organic material and duff is a bit deeper. The stream is low gradient with gravel and cobble bed.

Arrangements for storage on other than designated sites are the responsibility of the Contractor.

905.02 Material Sources

(a) Designated Sources. Sources for materials such as, but not limited to, soil, rock, or logs that are not available from trailway excavation or clearing operations will be designated. Sources of local materials designated in the SPECIFICATIONS or SHOWN ON THE DRAWINGS are guaranteed by the Government for the quantity of material in the source.

Use all needed suitable material from the source. The designation of a source includes the right to use areas SHOWN ON THE DRAWINGS for the purposes designated (such as plant sites, stockpiles, haul roads). Operations are restricted to the confines of the area(s) designated by the CO.

(b) Contractor-Furnished Sources. Furnish material that produces an end product equivalent in performance to that specified.

905.03 Restoration. Shape and grade borrow areas on Government-administered land to make them stable and to minimize future erosion. Dispose of debris resulting from development of material sources by chipping and scattering, unless otherwise specified. Do not scatter debris from within the clearing limits of trails or within roadsides. Cut off stumps to less than 12 inches above the ground as measured on the uphill side of the stump.

Section 906 - Measurement and Payment

906.01 General. Measurement and payment for contract work will be made only for and under those pay items included in the SCHEDULE OF ITEMS. All other work and materials will be considered incidental and included in the payment of the PAY ITEMS in the SCHEDULE OF ITEMS.

When more than one class, size, or thickness is specified in the SCHEDULE OF ITEMS for any PAY ITEM, suffixes will be added to the item number to differentiate between the items.

906.02 Determination of Quantities. The following measurements and calculations are to be used to determine contract quantities for payment:

Make measurements for seeding, geotextiles, and erosion control blankets along slope lines.

For retaining walls, measure by the square meter of front wall face.

Measure structures according to neat lines SHOWN ON THE DRAWINGS or as altered by the CO in writing to fit field conditions. Make measurements along the centerline and parallel to the specified grade or foundations or as SHOWN ON THE DRAWINGS.

Deduct length for stairways, turnpike, puncheon, retaining walls, wire baskets, switchbacks, bridges, and bridge approaches from the measurement of excavation in Section 912 unless these items are specified as incidental to excavation in Section 912.

For standard manufactured items, such as fence, wire, plates, rolled shapes, and pipe conduits identified by gage, weight, section dimensions, and the like, such identification shall be considered the nominal weights or dimensions. Manufacturer’s tolerances will be accepted unless controlled by tolerances in the cited specifications.

906.03 Units of Measurement. Payment will be made by units defined and determined according to US Customary system of measure. Unless otherwise specified, work will be measured as follows.

(a) Cubic Yard (CY). A measurement computed by one of the following methods:

(1) Excavation, embankment, or borrow. The measurement computed by the average-end-area method from measurements made longitudinally along a centerline or other reference line.

(2) Material in place or stockpiled. The measurement computed with the dimensions of the in-place material using average-end-area method or prismoidal formula.

(3) Material in the Delivery Vehicle. The measurement computed using measurements of material in the hauling vehicles at the point of delivery. Vehicles shall be loaded to at least their water-level capacity. Leveling of the loads may be required when vehicles arrive at the delivery point.

(b) Each (EA). One complete unit, which may consist of one or more parts.

(c) Lump Sum (LS). The quantities that denote one complete unit of work as required by or described in the contract, including necessary materials, equipment, and labor to complete the job.

(d) Linear Foot (LF). Measure from end to end, parallel to the base or foundation, or horizontal ground surface on which items are placed.

906.04 Methods of Measurement. One of the following methods of measurement for determining final payment is DESIGNATED ON THE SCHEDULE OF ITEMS for each PAY ITEM:

(a) Designed Quantities (DQ). These quantities denote the final number of units to be paid for under the terms of the contract. They are based upon the original design data available prior to advertising the project. Original design data include the preliminary survey information, design assumptions, calculations, and drawings. Changes in the number of units DESIGNATED IN THE SCHEDULE OF ITEMS may be authorized under the following conditions:

(1) As a result of changes in the work approved by the CO.

(2) As a result of the CO determining that errors exist in the original design that cause a PAY ITEM quantity to change by 15 percent or more.

(3) As a result of the Contractor submitting to the CO a written request showing evidence of errors in the original design that cause a PAY ITEM quantity to change by 15 percent or more. The evidence must be verifiable and consist of calculations, drawings, or other data that show how the designed quantity is believed to be in error.

(b) Staked Quantities (SQ). These quantities are determined from staked measurements prior to the construction.

(c) Actual Quantities (AQ). These quantities are determined from measurement of completed work.
