Construction

01040.40 General

(ADD) Habitat Log Placement – Log Placement consists of loading and hauling 160 agency-provided logs to the site and placing the logs in clusters at the locations shown on the plans, and as directed by the Project Manager. The logs are 7 inch to 36 inch in diameter (large is rare) and range in length (12 foot typical length).

Logs longer than 12 ft may be cut, depending on contractor's method of transport. Retain maximum length.

Log pickup location: the west end of Pacific Ave and at 77 N Garfield, Eugene.

See additional photos of the habitat logs provided in the Reference documents.

Where logs are located outside designated construction access haul routes, it is acceptable to use equipment to place logs. Coordinate access with Project Manager.

See plans for locations and description of log clusters.

01040.55 (c) Coir Fabric

At all edges parallel to spillway slope, coir is to be installed flat on finish grade of soil and anchored per 01040.23 (l). Do not fold edges except at terminal ends of fabric.

Measurement
