• 01 22 00 -1.5 OPTION 3

As written the scope of work is very unclear. Are we to include the cost of developing a new staging area, installing additional fencing, relocating the Contracting Officer's Office (and we assume the contractor's facilities), moving onsite equipment to a new area and then moving everything back to its original area on the project? And, relative to Option 3, what is the meaning of the last sentence in paragraph 1.5.1.1 that reads "Payment also includes full compensation for all cost associated with mobilization (60 percent) and demobilization (40 percent)"? Are we to duplicate our bid price for CLIN 0001 in addition to the costs for other work specified in CLIN 3001 for each of the 5 occurrences?

1-1 Government Response. Please reference Section 00 70 00, DFARS 252.236-7004 on page 68 of 75 which addresses Payment for Mobilization and Demobilization. The risk for discovery of cultural resources is higher in the Sacramento Valley including Hamilton City.

• 01 35 26 – 1.5.1.1 SITE SAFETY AND HEALTH OFFICER (SSHO)

Most small business contractors cannot justify the cost to employee a full time person that is qualified to serve as a SSHO on this project. And if they do, and that person resigns the position or is dismissed, the contractor most certainly would have to replace that person with an independent contractor or a person hired through an employment service company. Will USACE accept a SSHO that is not on the contractor's payroll?

1-1 Government Response. Section 01 35 26 - 10, para. 1.5.1.1 states "the contractor must employ a minimum of one competent person at each project site to function as the SSHO..." The intent is that the SSHO must be an employee of the prime contractor. On: Aug 03 2017 Current Request Status: Request Closed

The majority of small business contractors do not have enough engineering or supervisoral persons on their payroll that they can afford to dedicate one of those persons as a CQC manager and still retain the capability to manage their projects. And if they do, and that person resigns the position or is dismissed, the contractor most certainly would have to replace that person with an independent contractor or a person hired through an employment service company. Will USACE accept a CQC system manager that is not on the contractor's payroll?

Page 4 of 12ProjNet: Logged In User

1-1 Government Response. Section 01 45 00 - 6, para. 3.4.2 requires the contractor to "identify as CQC

System Manager an individual within the onsite work organization who is responsible for overall management of CQC and have the authority to act in all CQC matters for the contractor..."

Has USACE obtained an encroachment permit from Glenn County? If not, the bidders for this contract cannot include the cost of any unforeseen conditions the County may place on the successful contractor.

Also, given that GCID borrow areas C, D, E, and F are adjacent to State Highway 45 has USACE contacted Caltrans to determine what conditions it may place on the Contractor?

1-1 Government Response. USACE has not obtained an encroachment permit. Section 01 50 00, para. 2.2.4 requires the contractor to "obtain and adhere to an encroachment permit." On: Aug 03 2017 Current Request Status: Request Closed

Are there any areas designated as potential habitat for the yellow-billed cuckoo?

8/10/2017www.projnet.org/projnet/binKornHome/index.cfm?strKornCob=BicAdminClosedR...

1-1 Government Response. In general, Hamilton City is a potential site for western yellow billed cuckoo habitat. However, there are no known habitats within the footprint of this project. That being said, if a habitat is discovered during the prosecution of this contract, the measures identified in Section 01 57 20 - 19, para. 1.14.3.1 will be implemented.

• Note 11 on plan sheet CD301 states that borrow areas A, B, and C contain little or no usable borrow. Is the bidder to assume that sampling and testing of these areas will not be required and that no borrow material from those sites will be used?

2-1 Government Response. The intent of note 11 is to make the Contractor aware that no all areas designated as borrow areas contain usable fill, but may be used for stockpiling of topsoil/fill.

Section 31 00 00 - 6, para. 2.2.1 requires the Contractor to submit a "Borrow Site Soil Sampling Work Plan" within 7 days after the notice to proceed and at least 30 days prior to the sampling activities at any borrow site..." On: Aug 03 2017 Current Request Status: Request Closed

7089552 Contracting 31 00 00 Comment Classification: Unclassified\\For Official Use Only (U\\FOUO)

• 31 00 00 - 2.2.1 EMBANKMENT FILL MATERIAL

The second sentence of the third paragraph of this section stages that "The contractor must perform additional pre-construction sampling and testing of the borrow sites to further define their suitability for use on this project."

However, the specification does not state how many samples are to be taken. We request that the frequency of sampling in the borrow areas be defined. Because the number of samples and tests may not be quantifiable at this time we suggest that a CLIN be added to pay for each sample taken and tested.

1-1 Government Response. Section 31 00 00 - 11, para. 2.2.1 states, "The Government has performed limited testing... The contractor must perform additional testing... to further define their suitability for use on this project." This intent is to require the contractor to take the tests necessary to determine suitability.

Documentation of the borrow site sampling and testing will be captured in the "Borrow Site Soil Sampling Work Plan to be submitted within 7 days after the Notice to Proceed." On: Aug 03 2017 Current Request Status: Request Closed

Comment Classification: Unclassified\\For Official Use Only (U\\FOUO)

• 31 00 00 - 2.2.1 EMBANKMENT FILL MATERIAL

When will the decision be made as to when the borrow material is usable or not? The specification for embankment material (first paragraph of this specification) is very restrictive. The contractor will bear a lot of risk if the quality of the borrow material is inconsistent and the material is not approved until placed in embankment and tested.

If the contractor encounters pockets of unusable material that were not identified by the specified sampling program he and the Government will not know that until after the material is placed in the embankment and the QC tests are complete. That could entail removal of previously placed embankment and open up the subject of how to dispose of the unusable material.

We request that the specification be changed to allow for the embankment material to be accepted based on the results of the testing performed in the borrow areas.

7089555 Contracting 31 00 00 Comment Classification: Unclassified\\For Official Use Only (U\\FOUO)

• 31 00 00 – 2.2.1 EMBANKMENT FILL MATERIAL

We request that the specification define the minimum size, or quantity, of contiguous borrow area the contractor would have to excavate. Obviously it would not be productive if the contractor was made to chase small pockets of usable material. Also, the excavation of pockets of material would result in a lot of additional work to re-grade the areas to drain properly.

1-1 Government Response. Section 31 00 00 para. 3.7 states, "Unsatisfactory materials removed from excavations must be stockpiled for disposal."

Section 01 00 00 para. 1.21 requires the contractor to "locate a reliable commercial disposal site, and secure a disposal site as needed for the project." On: Aug 03 2017

• 31 00 00 – 3.3 EXCAVATION OF OBSERVATION TRENCH

If the Government's geotechnical engineer requires that the observation trench be deepened will the additional excavation be paid for as by a contract modification? Just paying for the additional excavation under the CLIN for Observation Trench Excavation would not be justifiable because the type of equipment and the productivity would most likely be much different than the planned work. In lieu of paying for the additional excavation by modification you could add a CLIN for "Over-excavation of Observation Trench".

1-1 Government Response. Thank you for the recommendation. However, an additional CLIN as suggested by this inquiry will not be added. On: Aug 03 2017 Current Request Status: Request Closed

Assuming through no fault of the contractor, if the Government's geotechnical engineer determines that the prepared subgrade is not appropriate for supporting the new fill, will the work required to correct the condition, and then re-compact and re-test the subgrade, be paid for as a change given that there is no pay item for such work?

1-1 Government Response. The Government will administer the contract based on the contract's terms and conditions. Should a situation arise as described in your inquiry, the Government will consider the facts presented at the time, and make a determination in accordance with the contract's terms and conditions.

• 31 11 00 – 1.4 IRRIGATION SYSTEMS and -3.6 IRRIGATION SYSTEMS REMOVAL In the specifications and on Plan Sheets C-101 through C-113 reference is made to existing irrigation systems that have to be removed in their entirety. Given that there is no possible way for a bidder to estimate the size, length, and depth of the existing irrigation systems we request that the Government more clearly define this work and how it is to be paid for.

A typical detail for the work is needed to define the excavation and backfill limits depending on the size of the pipe encountered. We also believe that the Government should add a CLIN to quantify the excavation and backfill quantities so that the contractor can be fairly compensated for the actual work completed.

1-1 Government Response. Paragraph 1.4 of Section 31 11 00 defines the expected extents of the irrigation systems. The removal extents will be modified as part of a forthcoming amendment. On: Aug 03 2017 Current Request Status: Request Closed

Please reference ProjNet ID #7089530. In the response the Government asked the bidder to specify what is confusing.

Page 9 of 12ProjNet: Logged In User

One thing that is confusing is the definition of a "Day". If the contractor's crew is actively working and the Contracting Officer stops that crew during the work shift for 4 hours until the CO orders the work to resume is that a day or a partial day or not day at all under this CLIN?

Another possibility is that a "day" for the purposes of this CLIN is intended to be for a 24 hour period in which the CO has ordered that no work is to be performed at all.

Please clarify.

On: Aug 03 2017. Forward request by email.

1-1 Government Response. The Government's intent is not to exercise this option and order the contractor to resume work on the same calendar day. The risk for discovery of cultural resources is higher in the Sacramento Valley including Hamilton City. In the event of a cultural resource discovery, the Government may exercise this option to require the contractor to standby at the contractor's proposed daily price (not to exceed 30 calendar days) while the Government completes the necessary consultation with the State Historic Preservation Office.

The time frame stated only allows offerors 6 working days to review and adjust to RFI answers, request subcontractor bids, receive competitive quotes, wrap-up the cost estimate, and prepare and ship the package, due on August 15, 2017, in light of this, we would respectively request a 14-day extension for this proposal to allow a more realistic and reasonable time frame for preparation and shipping of the proposal.

On: Aug 04 2017. Forward request by email.

1-1 Government Response. Please refer to the response for Inquiry ID 7091140. For most solicitations we issue, the FAR requires that solicitations be issued for a minimum of 30 days. Mission requirements as well as the scope, size and complexity of the project factor into the determination as to whether or not a solicitation should be issued for greater than 30 days. We consider these aspects well in advance of issuing the solicitation as the FAR requires that every acquisition have an acquisition plan. Considering those aspects of this project, we have determined 30 days to be reasonable. Historically, we close ProjNET for submission of new inquiries 10 days prior to proposal due date. Generally speaking, we have found great success with these timeframes. While we are sensitive to the pressures offerors are under to submit timely proposals, in this case, we have determined that it is not in the Government's best interest to extend the proposal due date at this time.
