Inquiry #15: Specification Section 12-3.24 MOBILE BARRIER SYSTEMS requires the use of Mobile Barrier Systems for most of the work on this project. Using Caltrans Mobile Barrier System Guidelines (dated December 2023), the estimated cost of one Mobile Barrier System is $2,000 per day. Per Section 12-3.24B, the rental cost for one Mobile Barrier Trailer is $25,000 per month. Additionally, the use of MBT’s will significantly impact production while installing the Multi Duct Conduit System trenches along the Caltrans ROW. These requirements will add substantial costs to the project. Please consider allowing the use of more typical Caltrans lane closures for this project (in particular for the new MDCS trenches).

Inquiry #17: On sheets E-3 to E-115 there are many contradicting instances where the lines and notes indicate a new length of conduit merging into an existing conduit with no notes indicating a continuation of the new conduit along the existing conduits or a method of installation were new conduits to be placed. Additionally, the provided Quantities tables contradict what is shown in the layouts.
For example: on E-9, near EB1 Line 174+75, there is a length of 137' of Note 77 (new 4-1.5" C) sweeping away from a run of notes 6 (Existing conduits, pull FO cables) & 78 (Existing, for reference only). The notes seem to imply that the 137' of note 77 is installed without continuing along with notes 6 & 78. Please clarify and/or correct what exact materials and methods are to be used.

Inquiry #52: An extensive estimating effort is needed for this project given it's overall length, the multiple types of underground raceway/trench sections, aboveground raceway/details for attaching to diverse concrete and steel structures, and providing traffic control for all the various work in a very complex urban transportation corridor.
The project's pricipal pay items, such as electrical systems, technology refresh, and traffic management, are lump sum items which means the bidders must pay much greater attention to the breadth and acccuracy of their material takeoffs (including fully vetting the table of quantities provided in the drawings) than would be necessary for unit price items, since the quantity risk for the lump sum items lies with the contractor.
Furthermore, another major Caltrans project similar in nature to this one has been postponed and is now bidding only one week prior to this project's bid date. The amount of estimating/bidding work crammed into such a short period of time is overloading not only our own estimators but those of our subcontractors and suppliers.
Considering all the above, we request that the bid opening date for this project be postponed by three weeks to allow bidders ample time to complete and review their estimates.

Inquiry #53: On Drawing E-5, the vault located at station “EB1” 123+50 lists fiber numbers 77 and 17. According to Drawing E-1 notes and ED-55, this conduit run is identified as the Bundle 3 fiber trunk line, consisting of 2 - 288 SM fiber optic cables, continuing along Route 880 from this vault. However, the electrical plans and cable assignment tables indicate that the Bundle 3 fiber trunk line is routed along Route 80/580 to the Route 80/780 junction, not along Route 880. Please confirm the correct bundle designation and routing of the fiber trunk line along Route 880.

Inquiry #60: I am trying to square up the cold plane, tack, and asphalt quantities associated with Bid Items 53, 54, and 55.
Summary of Quantities Sheet Q-1 points bidders to sheets C-1 to C-3 for these items.
Sheets C-1 to C-3 list tens of thousands of lineal feet of trenching in pavement.
The asphalt backfill shown on the ED plan sheets show a 4' wide pavement section.
350 SQYD of cold plane makes no sense when considering there are tens of thousands of lineal feet of trenching in pavement travel lanes. It is important to get these quantities as accurate as possible when bidders must also concern themselves with things like the 15% DBE goal.
Please confirm quantities for bit items 53, 54, and 55.

Inquiry #69: Sheets E-116 and E-117 do not clearly depict the quantity or exact locations of the detection loops to be replaced or installed as new as part of the TMS Refresh items.
Example:
Sheet E-117 shows a quantity of one (1) each for “New Detection (Loops)” with the item location noted as "ON-RAMP". The legend also indicates one (1) “Signal Head” at the same “ON-RAMP” location. However, the first TMS location listed on Sheet E-116, TMS ID: DTA41, Location: CLEVELAND AVE OFF-W-DIAG—refers to an off-ramp, which currently operates under stop control and does not have existing signal heads. Furthermore, Sheet U-137 does not show existing loops located on this Off-Ramp.
To ensure accurate takeoffs and bidding, please clarify the following:
• The correct quantity and placement of loop replacements per location
• Whether signal heads and detection loops are actually required at each listed TMS location
• Any discrepancies between the plans and field conditions
Clearer guidance is needed to properly quantify the work required for each Technology Refresh item.
