f. The PDF documents shall have a bookmark created in the navigation frame for each major entry (“Section” or “Chapter”) in the Table of Contents.

g. Thumbnails shall be generated for each page or graphic in the PDF file.

h. The opening view for each PDF document shall be as follows:

1) Initial View: Bookmarks and Page

2) Magnification: Fit In Window

3) The file shall open to the Company’s transmittal letter, with bookmarks to the left. The first bookmark shall be linked to the Table of Contents.

i. PDF document properties shall include the submittal number for the document title and Company’s name for the author.

j. Electronic submittal file sizes shall be limited to 20 MB. When multiple files are required for a submittal the least number of files possible shall be created.

8. Submittal Naming Convention. Company shall name submittal document files per the following naming convention:

a. PRJNUM-XXXXX-YYYZ – [Description] where

1) PRJNUM is the Engineer’s Project number, Charlotte Water 01300 - 3 February 2026

Primary Clarifier No. 4 Equipment Procurement CW Project No. FY26-ITB-08

2) XXXXX is the six-digit number corresponding to the specification section,

3) YYY is a three-digit submittal number,

4) Z is the letter signifying the initial submittal (A) and sequential resubmittals (B, C, D, etc.), and

5) [Description] is the description of what is being submitted.

b. For example:

1) Resubmittals

a) A resubmittal of the original or sequential resubmittal changes the “Z” lettering. The initial submittal of the Preliminary

Progress Schedule would be named: “193725-013216-001A –

Preliminary Progress Schedule”. If the submittal is Not

Acceptable (NA) or Returned for Correction (RFC) the resubmittal would be named: “193725-013216-001B –

Preliminary Progress Schedule”.

2) Submittals in same Section

a) For a new submittal within the same section of already existing submittals. If, for example, the “193725-013216-001A –

Preliminary Progress Schedule” has already been submitted.

Then a new submittal within the same section would change the “YYY” numbering. For example, the Progress Schedule submittal would be named: “193725-013216-002A – Progress

Schedule”.

9. The Company shall post submittals and retrieve Engineer's submittal review comments through the Project website accessible through the Internet. Instruction on procedures for posting and retrieving submittals will be provided after award of the Contract.

10. Facsimiles (fax) will not be acceptable. Submittals will not be accepted from anyone but the Company. Submittals shall be consecutively numbered in direct sequence of submittal and without division by subcontracts or trades.

B. Engineer's Review of Submittals.

1. Engineer's review of submittals covers only general conformity to the Drawings and Specifications, external connections, and dimensions that affect the layout; it does not indicate thorough review of all dimensions, quantities, and details of the material, equipment, device, or item covered. Engineer's review shall not relieve

Company of sole responsibility for errors, omissions, or deviations in the drawings

Charlotte Water 01300 - 4 February 2026

Primary Clarifier No. 4 Equipment Procurement CW Project No. FY26-ITB-08 and data, nor of Company's sole responsibility for compliance with the Contract

Documents.

2. Engineer's submittal review period shall be 21 consecutive calendar days and shall commence on the first calendar day following receipt of the submittal or resubmittal in Engineer's office.

3. When the drawings and data are returned with review status "NOT

ACCEPTABLE" or "RETURNED FOR CORRECTION", the corrections shall be made as instructed by Engineer.

a. The corrected drawings and data shall be resubmitted through the Project website.

1. The Company shall accept full responsibility for the completeness of each resubmittal. The Company shall verify that all corrected data and additional information previously requested by Engineer are provided on the resubmittal.

Resubmittals shall be in an organized and consistent format.

2. When corrected copies are resubmitted, Company shall direct specific attention to all revisions in writing and shall list separately any revisions made other than those called for by Engineer on previous submittals. Requirements specified for initial submittals shall also apply to resubmittals. Resubmittals shall bear the number of the first submittal followed by a letter (A, B, etc.) or a unique identification that indicates the initial submittal and correct sequence of each resubmittal.

3. If more than one resubmittal is required because of failure of the Company to provide all previously requested corrected data or additional information, the

Company shall reimburse the City for the charges of Engineer for review of the additional resubmittals. This does not include initial submittal data such as shop tests and field tests that are submitted after initial submittal.

4. Resubmittals shall be made within 30 days of the date of the letter returning the material to be modified or corrected, unless within 14 days Company submits an acceptable request for an extension of the stipulated time period, listing the reasons the resubmittal cannot be completed within that time.

5. The need for more than one resubmittal, or any other delay in obtaining Engineer's review of submittals, will not entitle the Company to extension of the Contract

Times unless delay of the Work is the direct result of a change in the Work

Charlotte Water 01300 - 5 February 2026

Primary Clarifier No. 4 Equipment Procurement CW Project No. FY26-ITB-08 authorized by a Change Order or failure of Engineer to review and return any submittal to the Company within the specified review period.
