1.2 Related Work
A. Section 01 33 00: Submittal Procedures
1.3 General Requirements
A. Pursuant to California Public Contract Code §3400, Deadline for receipt of Substitution Requests shall expire at 5:00 P.M. Pacific Standard Time, 7 calendar days before date of bid opening published in Notice Inviting Bids.
B. Standard Products - Where products are specified by reference standard, any product meeting the standards referenced may be used. Submit information on such products in accordance with the requirements of Section 01 33 00.
C. Proprietary Products – Where products or processes are specified by trade, patent or proprietary name, said specification, unless marked "no exceptions", or “City standard – no exceptions”, shall be deemed to be followed by the words "or accepted equal accepted in writing by City’s Representative." In such case substitution of similar products as “accepted equals” will be considered under this section.
D. Selection of Proprietary Product - Where more than one proprietary name is specified, Contractor may provide any one of the products specified.
E. Use only one manufacturer for each specific application throughout the Work notwithstanding that similar materials or equipment of two or more manufacturers or producers may be specified for the same application.
F. Systems of Like Manufacture - Where products are specified in groups to be furnished by one Manufacturer, no substitution will be considered that is not similarly furnished by one Manufacturer. Where Contractor proposes to use a system of equipment other than that shown in the Contract Documents, propose the substitution as a complete system.
G. Substitution Request Procedure Before Bid Opening - Submit written request on enclosed form for proposed substitutions to City Representative prior to deadline for receipt of substitution requests. Submit proposed substitutions relating to a particular subcontract or trade in one package. If City accepts any proposed substitutions, such acceptance will be set forth by addendum. No substitution will be considered after deadline for receipt of substitution requests has expired unless accompanied by an offer of savings to City.
H. Substitution Request Procedure After Bid Opening – City will only consider substitutions after bid opening if accompanied by an offer of savings to City in excess of $1,000. Submit written request on enclosed form to City’s Representative.
Submit proposed substitutions relating to a particular subcontract or trade in one package. If City accepts any proposed substitutions, such acceptance will be set forth by change order.
I. Contractor's Responsibility for Construction Modifications - Drawings have been detailed in compliance with dimensions and International Council of Building
01 63 00 – Product Substitution Procedures - Page 2 of 8 5-17-vw
Officials (ICBO) Evaluation Report data for products specified. If proposed substitute product is accepted by City’s Representative, Contractor shall assume both responsibility for construction modifications and additional costs required by reason of this acceptance. If substitution results in a decrease in cost, potential savings to City may be submitted to City’s Representative for consideration.
J. No time extension will be allowed for substitution of materials.
1.4 Standardization of Equipment and Certain Materials
A. Pursuant to Public Contracting Code §3400, the City may make findings designating certain “sole source” materials, products, things or services provided by specific brand or trade name for statutorily enumerated purposes.
B. Public Contracting Code §3400 is very often inapplicable to maintenance and construction projects performed by the City Department of Water and Power (DWP) on its water and wastewater utility systems.
C. When Public Contracting Code §3400 is inapplicable, the City’s general police powers authorize it to specify “sole source” equipment and products for a variety of reasons, including, but not limited to, the City’s need to establish uniform, complete and compatible equipment and product specifications, in order to help establish reliability, durability, uniformity, parts availability, repair and maintenance savings, and training improvements for the DWP staff.
D. Resolution No. 2013-057 adopted by the City on June 19, 2013 designated certain equipment and product specifications for construction of potable water, water reclamation and reclaimed water facilities.
E. Resolution No. 2013-057 gave authority to the DWP General Manager to review the adopted Specifications from time-to-time and to amend the Specifications upon making any findings required by applicable law.
F. Systems of Like Manufacture - To ensure standardization and uniformity in all parts of Work and to provide City with inter-changeability capabilities, simplified spare parts inventory, and standardized maintenance programs and Manufacturers' services, where products are specified in groups to be furnished by one Manufacturer, no substitution will be considered not similarly furnished by one Manufacturer. Where Contractor proposes to use system of equipment other than that shown in Contract Documents, substitution shall be proposed as complete system.
G. Material items exempt from standardization include structural steel, reinforcing steel, fasteners and bolting materials, building insulation, sheet metal, materials specified only by reference to recognized standard, and items hidden from view where interchangeability, color, and texture is no significant factor for standardization.
H. Contractor shall inform their suppliers and subcontractors of these requirements and shall provide necessary coordination to accomplish standardization specified.
I. Pursuant to California Public Contract Code §3400(b), City reserves right to reject product substitutions (1) on the basis of maintenance of economies of scale available to City through standardizing of Manufacturers and minimizing spare parts inventories, or (2) if City has provided in Invitation for Bids that the product is necessary to (i) field test or experiment to determine the product’s suitability for future use, (ii) match other products in use on a completed public improvement or one in the course of completion, (iii) obtain a necessary item only available from one source, or (iv) respond to an emergency declared in accordance with requirements of California Public Contract Code §3400(c)(4).

1.6 Definitions
A. Construction Joints: When fresh concrete is placed against a hardened concrete surface, the joint between the two placements is called a construction joint. Unless otherwise indicated, provide all joints in water bearing members with a sealant groove of the shape indicated.
B. Contraction Joints: Contraction joints are similar to construction joints except the fresh concrete shall not bond to the hardened surface of the first placement, which shall be coated with a bond breaker. Stop the slab reinforcement 4-1/2 inches from the joint; which is provided with a sleeve-type dowel, to allow shrinkage of the concrete of the second placement. Provide sealant groove unless otherwise indicated on the drawings.
C. Expansion Joints: Allows the concrete to expand freely by providing a space between the two placements. Form the joint as indicated. This space is obtained by placing a filler joint material against the first placement, which acts as a form for the second placement.
D. Control Joints: The function of the control joint is to provide a weaker plane in the concrete, where shrinkage cracks are expected to occur. Saw cut or form a groove, of the shape and dimensions indicated, in the concrete. Fill the groove afterward with a joint sealant material as specified.
