Denton Building Facility Change Order Explanations
2.0 Coring Hole, Fittings and Hand Trenching:
This is not included in the 1st change order cause at that time the existing smaller conduit was still
thought to be usable.
2.1 Moved to Change Order #1
2.2 Moved to Change Order #1
2.3 Concrete Wheel Guides:
After much discussion it was determined that a concrete wheel guide would more beneficial than a steel
pipe as in the plans.
2.4 8” Paving Between North Driveways:
After the 2 entrances were poured for the upper roads and the lower road in Northeast corner of site, it
was decided that connecting them together would be better for the public accessibility. This would also
tie in the pavement to the drainage inlet and outlet.
2.5 Doweling for Pavement Between North Driveways:
Due to the additional concrete between the 2 driveways listed in item 2.5 being placed after the
driveways were poured, doweling into the driveways was needed.
2.6 Stainless Steel Valve and Valve Box:
And additional valve and valve box was requested to provide more control and allow isolation to more
lines if needed.
2.7 Valve Extension for Water Shut‐Off:
The valve connection to the main re‐use water line near Cell 4, was located much lower than
anticipated. Therefor a custom designed, fabricated and fitted valve extension was needed.
DocuSign Envelope ID: 6136FCC2-1C36-48B6-A99C-B198D99D3C13
2.8 Over Head Profit as Per Contract:
This is based upon the contract 11.08.C.2.a on page 44 of 65. This was figured using lines 2.0, 2.4, 2.5,
2.6, 2.7, 2.19, 2.21, 2.22, 2.23, 2.24, 2.25, and 2.26 for a total of 29030.84 at 15% = $3,786.63
2.9 Deduction for Metal Wheel Guides:
This item was removed from the design at the City’s request.
2.10 Deduction of Lime Stabilization:
Once excavation began and the site was prepared it was determined that lime stabilization was not
needed, based on the existing soil classification.
2.11 Deduction of Building Pier:
Prior to the installation of the pier, the building design was changed to allow an egress point for the
truck drivers and the pier was no longer needed.
2.12 Deduction of Pier Cap:
As per line 2.11 since the pier was not needed, then the pier cap is no longer needed as well.
2.13 Does not exist
2.14 Moved to Change Order #1
2.15 Does not exist
2.16 Does not exist
2.17 Moved to Change Order #1
2.18 Does not exist
DocuSign Envelope ID: 6136FCC2-1C36-48B6-A99C-B198D99D3C13
2.19 Push Wall Drain Hole:
The city wanted a drain hole to be cored into the bottom of the center push wall to allow for water to
drain from behind the wall.
2.20 Does not exist
2.21 Push Wall Notches and Base Plates
To attach the armor plating to the push walls it was determined in the field to cut notches in the plates
to allow a weld to be created to the embed anchor. Then baseplates were requested to hide the welded
attachment points.
2.22 Chute Cover Plates for Gaps:
Between the top of Wall A and the deflector plates, by design there was a small gap. The city requested
that the gap be eliminated by welding in some additional metal to eliminate the gaps.
2.23 Litter Fence Anchors:
Additional anchors were requested to hold the littler fence down to the tipping floor.
2.24 Wall A Drain Extensions
On both sides of Wall A, under the stairs, it was decided to extend the weep hole drains further away
from the building. Rock was also placed around the outlet to help prevent structure damage of prevent
erosion.
2.25 Stair Land Thresholds:
Once the stairs and the concrete wheel guide was in place, it obvious that now the stairs need an
elevated concrete landing for safety.
2.26 Additional Handrails Behind the Push walls:
The City decided that handrails were needed a safety precaution.

Items 2.27, 2.29, 2.30 and 2.31 Concrete and Rebar Escalation
The escalation date stated on the original quote is only good if the quote is accepted in 30 days. We
usually have some play (30‐45 days) but not much.
In this case we did not receive award until several months later so the stated escalation date is no longer
applicable. Not accepting the quote within 30 days (noted on the quotes) also allows the supplier to
requote the project based on current market conditions.
This is the case for rebar and concrete.
Set escalation dates are standard for concrete and rebar suppliers due solely to inflation.
In addition to normal inflation, during the time this job was originally quoted to the time it was accepted
(2‐3months), suppliers dealt with shortages of labor, supplies and a global pandemic related to COVID‐
19. Also added issues the concrete supplies main source of cement for the DFW area was no longer
producing. Therefore, you see the large jump in concrete prices as well as the increased price of rebar.
2.27 Escalation Cost of Rebar
At the time of the bid the rebar was quoted for material and fabrication at a lump sum price of $77,015
and at the time the contract was awarded the price increased $89,555 for difference of $12,540. These
escalation costs were out of control in a worldwide pandemic, therefore leaving North Texas to hold the
bag on these costs should not fall upon them or Hammett.
2.28 Escalation Cost of Building:
At the time of the bid the price for the building was $263,064 but Hammett could not place the order
until the City had approved the design and given us a building permit. After that time and including the
reduction in cost for removing 1 column and some siding, along with the rise in prices due to the
pandemic, increased the building by $20,704.
2.29 Escalation Cost of Concrete Piers/Caps:
At the time of the bid the cost of the concrete for the piers and caps was $114 per cubic yard at the time
the contract was awarded the price was $120 per cubic yard. There was a total of 51 cubic yards at an
increased rate of $306. These escalation costs were out of control in a worldwide pandemic, therefore
leaving North Texas to hold the bag on these costs should not fall upon them or Hammett.
DocuSign Envelope ID: 6136FCC2-1C36-48B6-A99C-B198D99D3C13
2.30 Escalation Cost of Concrete Walls
At the time of the bid the cost of the concrete for the walls was $114 per cubic yard at the time the
contract was awarded the price was $120 per cubic yard. There was a total of 240 cubic yards at an
increased rate of $1,440. These escalation costs were out of control in a worldwide pandemic, therefore
leaving North Texas to hold the bag on these costs should not fall upon them or Hammett.
2.31 Escalation Cost of Concrete Paving
At the time of the bid the cost of the concrete for the paving was $110 per cubic yard at the time the
contract was awarded the price was $116 per cubic yard. There was a total of 2111 cubic yards at an
increased rate of $12,666. These escalation costs were out of control in a worldwide pandemic,
therefore leaving North Texas to hold the bag on these costs should not fall upon them or Hammett.

Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
