A. BID ITEM WORK:

a. Install all water main as detailed on the Contract Plans;

b. Potentially contaminated sites that may contain petroleum contaminated soils may be encountered in proximity of the water main installation. If the CONTRACTOR when beginning excavation in the vicinity of said site encounters any such conditions as described in Section 3.3.4 (PETROLEUM CONTAMINATED SOILS REMOVAL AND DISPOSAL), the CONTRACTOR shall immediately contact DISTRICT Staff and adhere to all provisions as set forth in Section 3.3.4 below.

CDF/Bentonite Trench Dam(s) (Bid Item No. 26) may be required for installation.

Such check dam and drainage shall be installed (if required) as field located by PUD staff. Additional CDF/Bentonite Trench Dam(s) may be required depending on water drainage conditions found during excavation. If required a two-foot-wide crushed rock filled ditch with 6” corrugated perforated drain pipe shall be installed as field located to provide suitable drainage. If required, the material excavated will be transported to a suitable disposal site as described below in Section 3.3.4;

c. For purposes of this Contract ALL trench materials excavated within the paved roadway will be hauled off and replaced with 100% 5/8” minus crushed rock backfill. The DISTRICT’s Geotechnical representative will ensure compaction meets the standard Engineering Design and Development Standards (EDDS) as prescribed by Snohomish County;

d. Those areas of excavation within the vegetative or gravel shoulder may use native backfill material given the approval of the DISTRICT’s Geotechnical representative including meeting the standard requirements of a 95% modified proctor density test. However, if weather conditions dictate, then 100% 5/8” minus crushed rock backfill shall be required for roadway shoulder excavation. The bid item for 5/8” minus crushed rock (Bid Item 15) reflects the potential for additional quantity to be used for such purposes. All road crossing and road asphalt cuts outside of the travel lane (i.e., asphalt road shoulder) shall be restored with an asphalt patch utilizing a “T-Cut” as detailed in the Standard Detail 801 and Section 3.9.2.2 of this Specification. All longitudinal trenches in the travel lane shall be restored via grinding and half-width overlay (unless otherwise specified on the Contract Plans);

e. Sod restoration is required for restoration for trenching across any lawn disturbed;

f. Control density fill (CDF) backfill shall be required for purposes of cross connection prevention in the case that the water main alignment is in proximity of sewer. The CONTRACTOR may also be directed to backfill areas surrounding utility crossings where sufficient separation cannot be achieved. Snohomish County requires that all existing water main to be abandoned in the Snohomish County right-of-way shall be cut, capped and filled with CDF after the new water main is placed in service. For purposes of utility identification, the CDF (in flowable form) shall be colored blue prior to installation. The quantities shown in the Contract documents reflect the potential for utilizing additional CDF for this purpose in addition to potential use in areas of contaminated soils;
