Section 108.01(b) on page 203 of 264 of the attached states “Do not mobilize or start construction operations before October 1, 2021.”
Given the location of the project, and a completion date of January 28th, a start date of October 1 will make it impossible to get the project paved out and adhere to the contract requirements not only for temperature but there is likely to be snow on the ground when paving would take place given that start date.
This requirement in SCR Subsection 108.01(b), and the fixed completion date specified under FAR 52.211‐10 on Page C‐20 is required. Please bid accordingly.

X‐Sections show reinforcement length being 11’ from face of wall versus plan sheet E.2 showing eight feet from face of wall. This is a significant difference, and it will drive the quantities for excavation, backfill, etc…..Are the X‐sections correct or are the plans correct?
In accordance with FAR 52.236‐4, “The Government shall not be responsible for any interpretation of or conclusion drawn from the data or information by the Contractor”; hence bid the plans when there are discrepancies with what is shown on the physical data cross‐section files.

X‐Sections – show a one foot section of material under the base of the wall and first layer of reinforcement. Plan Sheet E.2 shows material under the reinforcement and base of wall but does not indicated at what depth. What type of material goes under the base of the wall and first layer of reinforcement and at what depth?
This will be addressed under Amendment A001.

For Information Only quantities seem incorrect on Plan Sheet E.2 – Wall Area (SQFT) is 1,040.
Reinforcement Length, per Footnote (1) is 8’ minimum. (1,040 SF x 8’)/27=308 CY of backfill material at a minimum. Total Backfill provided from the For Information Only chart is 193 CY (Select Granular Backfill), 39 CY (Topsoil), and 7 CY (Granular Backfill) for a total of 239 CY. This is incorrect, as there must be at least 308 CY of backfill.
This will be addressed under Amendment A001.

Sheet E.2 The quantity of granular backfill does not appear to include both the confined material and the material behind the wall.
Please verify quantity.
We do not intend to change the information only quantity for granular backfill. Please bid accordingly. Note:
According to the MSE Wall Section on Plan Sheet E.2a (See Amendment A001), the specified material within the stabilized volume is select granular backfill, and the specified material behind the stabilized volume is embankment.

SCR 565.04 Construction sequence (d) it appears lean concrete is to be poured to an elevation that is below the OG. Typically lean concrete is poured back to the OG to prevent caving and to protect the pile during the structure excavation for the lagging. Lean is chipped to allow lagging installation from the top down. Please consider revising elevation.
This has been addressed under Amendment A002.

Section 555.18 – Erection states that certified steel erectors under AISC are required to be used to erect steel. The only steel being used on this project are the H‐Piles for the soldier pile walls. Typically this is done by the Drilled Shaft Foundation contractor and steel erectors do not typically perform this work. Because steel isn’t actually being erected and the H‐Pile are just part of the foundation for the Soldier Pile Wall this section should not apply to installing the H‐ Piles. Please advise.
This has been addressed under Amendment A002.
