Correction in Open Records Request To Trinity Watershed Management.

In my September 22 2014 request below, I had identified Borrow Area D AKA Borrow Area 3.

This should be Borrow Area D AKA Borrow Area 4. For further clarification, this is also located on the Burrescia property

noted in maps south of Elam Road.

Please note this correction in my request.

Greetings,

This is a request under the Texas Public Information Act.

Records relating to Trinity Watershed Management

Reference: Proposal Documents for Simpkins Remediation- Vegetative Support Layer PBSWM007, File NO. 428D-20, 251D-l. A Notice to all Bidders dated April 25, 2014. I have a 186 page set of records relating to this filing. I do not need an additional copy.

Clarification: Recently, I was told by officials ofthe Trinity Watershed Management that Borrow Area D, AKA Borrow Area 3, was originally designated for most if not all borrow soil needs for the Simpkins Remediation and additional facilities needs ( in conjunction with Borrow Area C south of Loop 12). The statements were that the City of Dallas determined that due to a stand of trees in Borrow Area D, and the desire to protect these trees, Borrow Area A was designated to provide soil needs for the Simpkins Remediation.

Request:

I request copies of all communications, including emails and communications reduced to writing, relating to the Borrow Area D, AKA Borrow Area 3, from the date January 1 2013 to date of this request.

This should include all communications between Trinity Watershed Management and the City Arborist relating to Borrow Area D.

If any contracts were let and signed for removal of soil from Borrow Area D, please provide a copy of the contract.

If you have any questions, please let me know. If this appears overly broad in scope, we can discuss narrowing the scope of this request.

Use this file . I think I was looking at your exhibit incorrectly. I believe your Lake A is theE & F areas in this file. Your lake

A (areas E & Fin the attached) is certainly viable but PK should look at all the utilities in this area.

Than,

Here is where we are with the borrow area. Think we 're pretty close but would like to:

1. Maximize Lake A/B excavatron . 2. Stay away from the Horse Park, or any areas not adjacent to the landfills (to minimize haul distances)

3. Explore Lakes C, D and E, or some variant of them.

Thanks,

Hi Jim,

Long time no hear. I know that the last t ime we met, we discussed the nearby offsite borrow source needed and how

the sand layer at the Burrescia property (5950 Elam Road) was needed for your project as a total of 450,000 cubic yards

of borrow material was needed north of Loop 12.

We discussed this internally and found a solution for this needed dirt as this borrow source will consist of 3 ponds; 2

new ponds (1 northwest of the western end of Elam Road and 1 on the northern portion of the Burrescia property) and

an enhancement of an existing pond near the entrance into the Horse Park; see enclosed figure. Pacheco Koch revised

the hydraulic modeling for the approved fill permit.

Let me know if you agree with the 3 ponds as the sand borrow source is still there.

The darker blue area should take care of everything. May be less than thls ... JUSt depends upon how deep we can

go. This is less area disturbed than the fill permit plan .

The lighter area south is if more •s needed.

To: Nguyen, Than Cc: Diviney, Patrick; Greg Sherman Subject: Simpkins Remediation - Rock Excavation, Other Issues

Than, As requested per your previous e-mail, here is the additional cost for rock excavation:

Based on a reduced depth of 16', this equates to an additional cost for 12,200 cu. )'ds (ii) $16 pc1·

cu.p..l. = SJ 95,200.00 If this material can be placed in a single layer in the bottom of the base ofthc structural fill, 12" to

18" pieces, then run O\-'Cr with a sheepsfoot compactor, then the additional cost fo excaYatc would be

$8.00 per cu. yd. x 12,200 cu. yd~;. = S97,600.00

I have review the plans and spec book for this and feel that additional compensation for rock excavation is not

justified. As stated within B-11 (Unclassified Excavation, Bid Item 103 & Alternate Bid Item 1), "Technical

Specification B-14 (Geotechnical Information} will apply for this project also." Within 8-14, it talks about

limestone fill material as shown in the Boring logs and Plan sheets. The boring logs were shown in the spec book

and plan sheets near the cross section pages. The soil stratums were presented in the bid documents (plans and

specification book) and the volume accounted for in the cross sections and the bid quantity of 656,418 cubic

yards of material needed. This was not an unforeseen existing condition and your proposed cost is unreasonable

also.

Additionally, at the pre-constructionlpartnering meeting today, Greg Sherman and Jim Barger (Oncor) had a

discussion and we w~:re asked to put some costs together for the following items:

I) Pond B -COD would like to eliminate and move that quantity, if needed, to Pond A (east) ..... Aud .'50.50

per cu. yd to the Fill Area #2 lJUntcd unit price of S2.25 per cu. yd ..... 81 ,315 CY x SO.SO = $40,457.00

additional cost Per Addendum Ill, Note 119 says 'The primary borrow sources (in order of priority} are Borrow

Areas A, C, 8, ond D. Barrow Area D will only be used is the City decides to not use Borrow Area 8 or additional

soils are needed. The calculated amount of borrow dirt needed is 625,160 cubic yards as this amount can be

obtained from Borrow Areas A and C together. The City will decide on the borrow areas used for this project as

the grading plans for the borrow areas may change". Note #16 says 'The bid quantities for Bid Items 103

{Unclassified Excavation), 1341 (Transport Dirt to Fill Area 1}, 1342 (Transport Dirt to Fill Area 2}, 1343 (Transport

Dirt to Fill Area 3}, and 1344 (Transport Dirt to Fill Area 4} will not be renegotiated based on overages or

underage of these bid items." This additional cost is unjustified.

If any contracts were let and signed for removal of soil from Borrow Area D, please provide a copy of the contract.

If you have any questions, please let me know. If this appears overly broad in scope, we can discuss narrowing the scope

of this request.

2) Pond C a) Haul limestone to structural fill area .... add $2.25 per cu. yd. to the fill area #2 quoted unit

price of $2.25 prr cu. yd ...... I 2,200 cu. yds. x S2.25 = $27,450.00 additional cost This is

already paid for in Bid Items 1341, 1342, 1343, and 1344. The Bid Item 1346 is to include survey

staking, compaction, and geotechnical testing. Per Addendum Ill, Note 1115 says "For Bid Alternate 3

(Bid Item 1346- Process/Compact Fill at Structural Fill Locations), payment far this item will include

survey staking, compaction, and geotechnical testing as this will be considered incidental to the bid

item. Additional fill allowance shall be not be stockpiled and bidders are to assume an average haul

distance to the center of each fiJI zone for this additional fill material. All additional fill material shall

be spread by others."

b) Haul approx. I 6,000 cu. yd. of sand from Pond "C" to Fill Area #2 ... . add $2.75 per cu. yd.

= S4.:f,OOO.OO additional cost Per Addendum #1, Note #5 says '7here are 4 identified soil stratums in the

borrow areas; clay, silty clay, limestone, and high quality sands. Landscapes Unlimited would like for soils from

these stratums to be placed in specific areas within the fill areas as they will be spreading of the fill. Due to the

size of the borrow areas and soil stratum depths, the amount of dirt from each stratum of each borrow source

will be substantial sa this will not delay the Contractor's construction schedule. The Contractor will not be

responsible for determining these soil stratums or the associated depths as Landscapes Unlimited will inform the

Contractor on the depth and placement of this material in regions within the fill areas. However, Landscapes

Unlimited requests that the Contractor use best efforts to inform Landscapes Unlimited when contractor observes

a significant change in soil type, stratum, or encounters ground water during eKcavations." If the intended area

for this sand is in another zone not planned, that Fill Zone price will apply.

3) Structural fill a) East parking lor will not be filled to Q l 00. This lot will be filled to a .5% grade from

existing to the south. How much is this reduced? See revised structural fill area email sent earlier today

b) Emergency access road till eliminated. How much is this reduced? See revised

pothole and verify the existence of any existing utility line in both areas as payment will be made through Bid

Item 1652 (Locate Underground Utility Not Under Paving) for each of the 2 lines. Field verification is needed to

acres with a bid quantity of 35 acres as this is estimated for the borrow areas only.

There may be some additional areas to clear and grub in the fill areas.

5. There are 4 identified soil stratums in the borrow areas; clay, silty clay, limestone, and

high quality sands. Landscapes Unlimited would like for soils from these stratums to

be placed in specific areas within the fill areas as they will be spreading of the fill . Due

to the size of the borrow areas and soil stratum depths, the amount of dirt from each

stratum of each borrow source will be substantial so this will not delay the Contractor's

construction schedule. The Contractor will not be responsible for determining these

soil stratums or the associated depths as Landscapes Unlimited will inform the

Contractor on the depth and placement of this material in regions within the fill areas.

However, Landscapes Unlimited requests that the Contractor use best efforts to inform

Landscapes Unlimited when contractor observes a significant change in soil type,

stratum, or encounters ground water during excavations.

6. The estimated amount of dirt to be processed by the Contractor is 5,000 cubic yards a

day as the intent is to place the dirt in front of the earthwork equipment for Landscapes

Unlimited to grade. If the Contractor processes more than 5,000 cubic yards a day (or

more than Landscapes Unlimited can handle), an agreed upon stockpile location will

be given within the fill areas to not slow operations by the Contractor.

7. For Alternate Bid 2 (Bid Item 1345A- Clay Cap for Borrow Areas A, B. and/or D), the

Contractor shall install an 18-inch clay liner using native clay material having a

minimum plasticity index of 25 and compact to 92%-98% at or above optimum

moisture content to all areas under normal water surface elevations. Seal all

permeable areas to restrict seepage from the ponds as no separate payment will be

made.

The City will procure a local geotechnical firm for this testing. The Contractor shall pay

for any retesting fees not meeting these requirements. Payment for Bid Item 1345A

will include unclassified excavation. transport to the fill area, and compaction.

Payment will be based on a ground survey before and after by a Texas Registered

Professional Land Surveyor (RPLS) and a summary report as this will be paid by the

Contractor. Import material can be used and will be paid through delivery tickets.

8. As clarification for General Note #44 on Page 2 of the plans, a trench burn pit will not be

allowed on the landfill footprint due to safety concerns. However, a trench bum pit will

Page 3 of 7

Simpkins Remediation -Vegetative Support Layer (PBSWM007) -Addendum #1

be allowed at a minimum distance of 500 feet away from the landfill footprint as the

Contractor will obtain approval from the Texas Commission on Environmental Quality

and Dallas Fire Rescue. The trench burn location must be approved by the Engineer

as a trench burn pit may be allowed near Borrow Areas A. No payment will be made

for removal of additional trees to accommodate this trench burn. The Contractor shall

verify if the trench burn pit is located within the landfill permit.

9. The primary borrow sources (in order of priority) are Borrow Areas A, C, B, and D.

Borrow Area D will only be used is the City decides to not use Borrow Area B or

additional soils are needed. The calculated amount of borrow dirt needed is 625,160

cubic yards as this amount can be obtained from Borrow Areas A and C together. The

City will decide on the borrow areas used for this project as the grading plans for the

borrow areas may change.

10. As clarification for Bid Item 222A (Dewatering for Borrow Area D) -Alternate Bid 1, this

bid item will also apply during the installation of the clay cap until it is completed. No

additional payment will be made for dewatering associated with Alternate Bid 2.

11.As clarification for the cubic yards and bank yards notes shown on the fill area plan

sheets, those 2 numbers reflect the range of dirt volumes that could be brought to that

fill area as the final layout has not been finalized to date. The grading plans are for

information purposes only as Landscapes Unlimited will perform the spreading of the

fill material.

12. This is a closed landfill project as the 40-hour safety trained in accordance with 29 CFR

1910.120 is not required but recommended. Borrow areas are not located within the

landfill footprint.

13. This project will start subsequent to the start of the 1st City project mentioned above but

shall run concurrent with such project. It is recommended that the Contractor follows

the same sequencing as the 151 City project.

14.1f there are exposed waste as a result of the Contractor's recent construction activities,

the Contractor shall place at least 2 feet of clay material on top of this area and inform

the Engineer as this will be considered incidental with no separate payment.

15. For Bid Alternate 3 (Bid Item 1346 - Process/Compact Fill at Structural Fill Locations),

payment for this item will include survey staking, compaction, and geotechnical testing

as this will be considered incidental to the bid item. Additional fill allowance shall be

not be stockpiled and bidders are to assume an average haul distance to the center of

each fill zone for this additional fill material. All additional fill material shall be spread

by others.

16. The bid quantities for Bid Items 103 (Unclassified Excavation), 1341 (Transport Dirt to Fill

Area 1 ), 1342 (Transport Dirt to Fill Area 2) , 1343 (Transport Dirt to Fill Area 3), and

Page 4 of7

Simpkins Remediation- Vegetative Support Layer (PBSWM007) -Addendum #1

1344 (Transport Dirt to Fill Area 4) will not be renegotiated based on overages or

underage of these bid items.

17. The Engineer (Than Nguyen), or an approved assignee, will sign all offsite waste

manifests.

18. On the plans, there is an existing DWU wastewater easement along Elam Road and a

United Gas easement in Borrow Area B. The Contractor shall pothole and verify the

existence of any existing utility line in both areas as payment will be made through Bid

Item 1652 (Locate Underground Utility Not Under Paving) for each of the 2 lines. Field

verification is needed to determine if existing lines are still present or ever installed.

All bidders shall be required to add the following sentence to the inside of the front cover sheet of

the special Provisions and Proposal with signatures:

--------------~--~~--~~--~~~------------------ acknowledges (Give Legal Name of Organization)

Receipt of Addendum No.1, and has taken due cognizance of the said addendum in all its forms

in the preparation and submission of this bid .
