BIDDER’S QUESTIONS AND GOVERNMENT REPLY

(Questions that may be of general interest to all Bidders and/or the Government and that are not readily answered by the proceeding changes will appear below. These questions may have been paraphrased or altered to represent several questions regarding the same subject and/or simply revised to clarify and simplify the question(s). Questions and answers are issued to the bidders “For Information Only” and do not revise the solicitation, plans or specifications.)

Question 1:

Not used.

Government Response:

Not used.

Question 2:

I don’t see any deadline for questions, is there one? Also confirming all questions should be emailed to you?

Amendment #1 was posted and indicated the bidder inquiry due date - 05 JUL.

Question 3:

Please change the unit of measurement for the disposal from CY to Tons since this is typically what is used in the industry. In addition, we do not know how wet the material will be, therefore, we will not know the conversion needed.

Unit of measurement will not be changed from CY to tons. Design team has determined that measurement of volume to weight is more appropriate for this project.

Question 4:

How are we to get paid for the 2’ over excavation and the fill required to put back in place of the over excavation. Also, please provide clear limits of the operation.

"1.4.1.1 Payment Payment will be made for costs associated with work included in this line item consists of but is not limited to excavation, temporary storage, and offsite transportation of approximately 4,200 cubic yards of contaminated material within the existing pond side slopes and bottom.

Approximate locations of contaminated material are shown on the drawings and referred to as "Over-excavated Material" or "muck" in the bottom and sides of the existing pond/reservoir. This unit cost line item shall include any other items incidental to excavation, handling and offsite transportation of contaminated material not defined as having a specific unit cost. This unit cost line item shall include backfilling the excavated volume."

"1.4.1.2 Unit of Measure Unit of measure: Cubic Yard"

Question 5:

Please note that the Scale on the plans have two different “scale sizes” Please correct plans to have the proper scale.

Scaling on drawings will be corrected and an addendum submitted for revised drawings.

Question 6:

Many of the Drawings have been reproduced with extremely line weight for showing the existing conditions, the description of existing conditions and the Arrows and Arrowheads pointing to Proposed features.

This makes it difficult for us to know what work is intended to be performed. Please review the line weights on the drawings and re-issue them with corrected line weights. The most important are

• Dwgs C-002 thru C-005

• C-008, C-009

• C-016 thru C-020

Grey line weights are for existing conditions/reference only.

Question 20:

It appears there is an error with the scaling on this project which make the plans not usable.

Question 21:

Please take a look at the “MATCH LINE: on Dwg C-004. Next, please take a look at the “MATCH LINE” on Dwg C-005. These lines do not match. Using an Engineer’s Scale of 1” = 20’ (which is not correct, the Drawings are not drawn to scale) there is a gap of approx.

13’ between the 2 “MATCH LINES.” Please correct the Scale and please correct the Drawing such that it is a true “scale drawing” from which we may take measurements to compute quantities.

Scaling/matchline on C-004 and C-005 will be corrected. See Addendum 1 for revised drawings.

Question 22:

Plans call out the pond infill to be compacted fill and drawings C-006 and C-007.

Excavation and Fill specification 312300 does not describe “compacted fill” materials. Is considered structural backfill material? If not, please provide a specification on the compacted fill materials.

Refer to Geotechnical Note 5 on G-004 for clarity regarding Compacted fill & structural backfill.

Government Response:

Not used.

Question 28:

Referring to sheet C-020 of the plans, Note 1 states to "install 3 rows of stacked hay-bales centered on existing ditch bottom", "placed as shown." Sheet C-020 does not specify where the stacked hay-bales are to be placed. Please clarify the location of the proposed hay-bales.

Note on C-020 for hay-bales will be removed. See Addendum 1 for revised drawing.

Question 29:

Referring to sheet C-020 of the plans, Note 1 states to "install 3 rows of stacked hay-bales."

Question 37:

Not Sure if there was a bad data transfer or not but scale is off on multiple plans and the match line between C-004 and C-005 seems to be missing 13’ off or missing data.

Scaling and matchline on C-004 and C-005 will be corrected. See Addendum 1 for revised drawings.

Question 38:

Main fill material calls out to be compacted fill yet don’t see that referred to in the specs can you issue a spec for that material?

Question 39:

I also have alignment issues when I overlay the 2ft under cut from demo plan( C-002) and the drainage layer from sheet C-005,the drainage layer is outside of the under cut area And that doesn’t exist on any profile.

The drainage layer is set at a higher elevation than the bottom of the pond in some cases and will exceed the pond bottom outline in area. C-005 shows an approximate limit of pond bottom excavation. The elevation for this will vary, while the drainage layer will differ in some cases per C-006 and C-007 and C-011 through C-017.

Question 40:

It appears there may be a scaling issue with the plans that were provided. Can you please review drawings and advise.

Question 41:

Please confirm all compacted fill shall meet the requirements of "select Fill" as specified in specification section 31 23 00.00 20 and mentioned in note geotechnical note 5 on drawing G-004

Please advise on how the contractor is supposed to access the end of the existing and proposed outfalls as this appears to be outside the limits of work and would appear to be from the existing parking lot

The maintenance road will be called out on C-001. See Addendum 1 for revised drawing.

Question 44:

The stone layer shown on the profile drawing, drawing sheet C-006 shows the layer to terminate prior to station 12+00 while the plan drawings show the layer to extend beyond station 12+00, please advise as to what the correct limits of the stone drainage layer are?

Drawing C-006 will be revised to show limits of stone drainage layer. See Addendum 1 for revised drawing.

Question 45:
