Proposed New Standard Special Provisions
Log No.	Description	Due Date for Comments
613-1-fy23	Add specification requirements, construction requirements, and pay items for pull boxes. New – 613.02(d) provides new specifications for pull boxes. Update – 613.07 provides update to conduit construction requirements. New – 613.08 provides new construction requirements for pull boxes. Update – Shift 613.08 through 613.14 to 613.09 through 613.15 and update payment for work items	Sept. 7, 2023
713-1-fy24	Reflective devices quality requirements were outdated. Revised specification with latest testing methods and language for such devices.	Sept. 7, 2023
713-2-fy24	Colorado does support the use Permanent Raised Pavement Markers as they can be damaged from snowplows. Added Temporary Raised Pavement Marker language for Chip Seal and Seal Coat projects to 713.18 and left permanent language as it is used on a case-by-case basis.	Sept. 7, 2023
105-2-fy23	The electronic signature language will give guidance to the CDOT project personnel on the definition of the different types of electronic signatures and define when and on what type of documents require the electronic signatures.	June 1, 2023
106-2-fy23	The 2023 Spec book is adding in the requirements of 106.11 Buy America, but as a result the project specific revision of section 106.11 needs to be revised to remove additional requirements for non-fed aid projects.	June 1, 2023
106-3-fy23	The requirements for COC’s and CTR’s currently includes the project number. For manufacturers that provide the same products for numerous projects, this was difficult to obtain. The change allows manufacturers to certify that a product meets CDOT requirements without requiring them to create individual COC’s or CTR’s for each project. The language was also updated to allow electronic signatures on COC’s and CTR’s.	June 1, 2023
107-1-fy23	Contractors working for the State of Colorado can apply for a tax exemption on state sales tax for materials permanently incorporated into the work. Currently, the spec reads the Contractors have to pay all taxes, which has led to confusion as to if they can get a tax exemption or not or if they should bid a tax exemption or not.	June 1, 2023
107-2-fy23	There is a possibility of structure instability when new holes are drilled adjacent to existing sign structures. This specification change identifies this situation as safety critical and alerts the Contractor to their responsibility.	June 1, 2023
108-1-fy23	Liquidated damages are re-calculated and adjusted accordingly every two years. The revised amounts shown in the attached have been reviewed and approved by FHWA.	June 1, 2023
213-1-fy23	The Standard 213 called out a ASTM for Mucilage testing that is not provided in submittal cut sheets by the manufacturer. The terminology was changed for consistency for tackifier to mulch tackifier. This specification will be completely revised in the next couple of years for clarity.	June 1, 2023
214-1-fy23	The Standard 214 uses the term gallon to describe plant nursery container sizes. Gallons are not recognized by the ANZI Z60.1-2014 American Standard for Nursery Stock. Buyers and sellers of nurserry stock require a common termininology in order to facilated transactions. The landscape architecture section receives inquiries from both nurseries and consultants questioning the use of gallon containers in the Standard 214. From the ANXI Z60.1-2014 1.1.3 "Specifications for container grown nursery stock shall include a container class specification, in accordance with Table 1, below, in addition to the plant size specification. Containers marketed and sold that indicate a “trade” or “#” designation must have volumes within the ranges shown in Table 1 in order to comply with this standard." 1.1.3.4 "Each container class includes a range of acceptable container volumes, and is not limited to a single container volume (e.g., a certain number of “gallons”). The volume ranges for container classes #1 through #100 include the volume of a container that, if such a container were manufactured, would hold the equivalent number of gallons as the container class number. Standard users should refer to container manufacturers' volume specifications for compliance with the Standard. Nursery stock specifications that reference only an imperial volume measurement, such as “quarts” or “gallons,” are not in accordance with the Standard."	June 1, 2023
401-1-fy23	We are converting the current D-614-1, Safety Edge for Pavement into a full M-Standard with some minor updates. The spec needs to be reviewed and updated to match all of this.	June 1, 3023 Revised from March 3, 2023
601-3-fy23	The MAC has discontinued the use of the Super Air Meter. Standard Special Provision "REVISION OF SECTION 601 CONCRETE MIX DESIGNS" dated October 1, 2022 has been discontinued and should not be included on future projects. It may remain on existing projects are those under advertisement. Please delete the revision from the specification website.	June 1, 2023
627-1-fy23	Update minimum and maximum ranges of paints and stripes to include high build (15 Mil) pavement marking paint and basis of payment.	June 1, 2023

401-1-fy24	There is a discrepancy in the language in 401.17 Compaction Pavement Test Section (CTS). At the MAC meeting, a discussion was held, and all agreed to change the language to the 2012 version with edits to the words “may be” to read “at the engineer’s discretion” or “shall”.	Sept. 7, 2023
