An approximate 200-ft by 30-ft extension of the paved access road is being constructed for access and future communications tower construction. The new 4-foot high retaining wall is being constructed along the edge of the asphalt pavement extension to support the northerly edge of the pavement extension. The City retaining wall standard does not include a railing. Therfore, a fall barrier needs to be be provided as a safety measure along the top of wall where the upper finish grade is accessible by vehicles and personnel. The 3 foot high cable rail system is a Caltrans standard construction detail and will be constructed on top of the retaining wall.

Subject: Proposal for Cable Railing Fence to Retaining Wall AKM Email Dated March 8, 2021
Mr. Weisman:
REV 1: Revised per comments dated 3/26/21. See attached Notes to Reviewer page for PHC responses to these comments.
In response to an AKM email dated March, 8th 2021, The City has requested a proposal to procure and install a new Cable Railing Fence to the CMU retaining wall east of the new driveway. This fence will be per the attached Cal-Trans standard drawing.
Please note that the Cal Trans drawing provided was intended for a cast in place concrete wall, and not a CMU retaining wall. PHC will be grouting the posts into the CMU cells with an embed depth of 12”. This way the posts will be embedded 4" +- into the second course of block. Additionally, there will be a step in the railing height to account for the T.O.W elevation changes. PHC will keep the railing at 3’ from top of block consistent for the entire length of the cable railing fence as shown in the attached New Construction detail.
Please review the proposed lump sum cost below:
Cable Railing Fence to Retaining Wall Total .............................................................. $8,850.80 Scope of work detailed above includes all necessary tax and mark up, including bonds and insurance.
See attached for breakdown, and backup documents.
