STATEMENT OF WORK

Siuslaw National Forest, Central Coast Ranger District Wastewater System Upgrades at Sutton and Carter Lake Campgrounds, 2010

PART 1 – GENERAL

1.01 CURRENT CONDITION

A. Sutton Campground is divided in four loops and two areas: loops A, B, C and D; a group picnic area; and a beach area. Each loop or area has at least one flush toilet with its own wastewater treatment system. Each wastewater treatment system consists of a gravity fed system with a septic tank and a standard drain-field.

B. Original wastewater systems at Sutton CG were developed and constructed in the mid 1970’s. Two flush toilets were replaced a few years ago along with other upgrades.

C. Three flush toilets and their correspondent sewer systems at Sutton CG will be replaced this 2010 spring. These sewer systems will be converted from gravity fed systems to pressurized systems.

D. Another flush toilet in the picnic area will be replaced, but the existing drain-field may remain operational and in service. An optional item to remove the old septic tank, install a new septic tank, and replaced the existing drain-field is considered under this contract (see optional items).

E. Carter Lake Campground consists of one loop. The campground has one flush toilet with its own wastewater system. The current system uses a septic tank, a dosing tank, and a gravity fed system drain-field. The effluent from the septic tank is pump uphill to the dosing tank.

F. Original wastewater system at Carter Lake CG was developed and constructed in the mid 1970’s. A few years ago, the old flush toilet was replaced with a new flush toilet.

The new toilet was built in a different location, but the existing drain-field was kept in service. A new septic tank was installed next to the new building structure but the old septic tank was kept in service to be used as a dosing chamber. The dosing tank delivers effluent via gravity to the existing drain-field.

G. A new pressurized drain field, serial distribution, at Carter Lake CG will be installed to eliminate the dosing chamber and replace the old gravity drain-field. The old 1,000 gallon concrete septic tank (dosing chamber) will be removed and the existing pump will be replaced to provide adequate pressure and equal distribution.

1.02 PROJECT SUMMARY: This work consists of upgrading three (and possibly four) wastewater treatment systems at the Sutton Campground and one wastewater treatment system at Carter Lake Campground.

B. 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 items to be bid.

1.02 DETERMINATION OF QUANTITIES

A. For individual construction items, longitudinal and lateral measurements for area computations will be made horizontally or corrected to horizontal measurement unless otherwise specified.

B. The average end area method will be used to compute volumes of excavation or embankment. However, if in the judgment of the CO, the average end area method is impractical, measurement will be made by volume in hauling vehicles or by other three dimensional methods.

C. Structures will be measured according to lines SHOWN ON THE DRAWINGS or as altered by the CO in writing to fit field conditions.

D. For items that are measured by the linear foot, such as pathways, sewer lines, and water lines, measurements will be made parallel to the base or foundation upon which the structures are placed.

E. For aggregates weighed for payment, the tonnage will not be adjusted for moisture content, unless otherwise provided in SPECIAL PROJECT SPECIFICATIONS.

F. For vehicular shipments, net certified scale weights or weights based on certified volumes will be used as a basis of measurement. Measurements will be adjusted when bituminous material has been lost from the vehicle or the distributor, has been wasted, or has otherwise not been incorporated into this work. Determining true weights of hauling vehicles shall be made by weighing the empty vehicles at least once a day at the times the CO directs. Each vehicle shall bear a plainly legible identification mark.

G. When bituminous materials are shipped, net certified weights, or volume corrected for loss of foaming, can be used for computing quantities.

H. For standard manufactured items, such as fence, wire, plates, rolled shapes, pipe conduits, etc., identified by gauge, weight, section dimensions, etc., such identification shall be considered the nominal weights or dimensions. Unless controlled by tolerances in cited specifications, manufacturer's tolerances will be accepted.

1.03 UNITS OF MEASUREMENT

A. Payment will be by units defined and determined according to U.S. Standard measure as follows:

Acre – Make longitudinal and transverse measurements for area computations horizontally.
