SUBJECT: F.Y.2012 Lincoln Elementary School Safe Routes to School (SRTS)
Contract No. 805
Change Order #1
Submitted by: W. Wayne Castle, PLS, EI, Associate Engineer
Recommended City Council Action:
Approve and direct the City Engineer to sign the Change Order #1 documents.
Summary Statement
AECOM (the consultant) is attempting to close out this project. This Change Order is needed to meet
DOT requirements which will allow the project to be closed and formally accepted by City Council.
Expenditure Required: $21,141.00
Source of Funds: Iowa DOT Safe Routes to School grant and General Obligation Bonds
Policy Issue: Sidewalk in -fill
Alternative: None
Background Information:
Construction on this project was completed in the fall of 2012. The consultant has been working on the
construction documents for the past year. They have had issues getting quantity confirmation and
signatures from the contractors. Items covered in this change order were crucial parts of the construction
and were constructed to allow the project to be completed. Items in this change order have been paid for
under pay estimates previously submitted to Council for payment approval.
The main items in this Change Order that caused it to exceed the $20,000 City Engineer's approval limit
were the construction of PCC sidewalk and driveways. The consultant originally had minor amounts of
sidewalk replacement in driveway sections. With the recent United States Department of Justice (USDOJ)
push for enforcement of Americans with Disabilities Act (ADA) compliance on federally funded projects,
the DOT revised the requirements for sidewalk designs. This project was nearly to bid letting when these
revised requirements hit. Redesign of the sidewalk sections revealed that many driveways would have to be
reconstructed to allow the sidewalks to meet ADA specifications. To appease property owners, construction
of PCC driveways was to be done with a quick setting M-4 mix, not the standard C-4 mix. The change in
mixes added cost, but allowed driveways to be used after 24 -hours as opposed to 7 -days.

A - Description of change to be made or extra work to be done:
7001: Decrease the quantity for Item 0070, "Sidewalk, P.C. Concrete, 4 In." from 1,380.8 SY to 1,333.8 SY. (Participating)

8003: Add Item, "Driveway, P.C. Concrete, Class M, 6 In." in the amount of 283.8 SY. (Participating)
B — Reason for change or extra work:
7003: Additional clearing and grubbing of brush along Newton Street from Sta. 201+94 to Sta. 202+34 that was needed to grade 4:1 slopes in this area.
7004: The additional excavation is for the extra grading on Newton Street in front of 526 Longfellow Ave. and 606 Longfellow Ave.
7001 7001, 7005 and 7007: These items were revised mainly due to the change in design concept along Longfellow Ave. from Sta. 513+30 to Sta. 526+ 65.
The original concept called for inserting the sidewalk in to the driveways. This concept did not meet the new ADA standards as far as cross slope. To meet the
new ADA standards, the driveway approaches were removed and replaced. See the attached revised Tabulations 113-1, 110-5 and 110-8 for more details.
7006: The material for the "Detectable Wamings" was changed to specify the use of cast iron truncated dome / detectable waming panels.
7008: The quantity of retaining wall was increased in front of 526 Longfellow Ave. and added to the sidewalk along 622 Longfellow Ave. The extra retaining
wall was needed to fit the conditions identified in the field.
8001: Item is as described in the Specification 2301. Cold weather protection was needed along Longfellow Ave. from Sta. 518+61 to Sta. 526+61.6. The cold
weather protection was needed due to the time of year the paving occurred. The paving occurred within the working day requirements stipulated within the
contract.
8002: HMA was needed to at various locations along Longfellow Avenue from Sta. 514+00 to Sta. 526+00 and on Parker Street in front of Concordia
Evangelical Lutheran Church. The HMA provided a smooth connection to the new driveway approaches and sidewalk to the existing asphalt street and parking
lot. The quantity was based on the estimated areas and depths and the size load of HMA in tonnage provided to complete the task. The method of
measurement is as per plan of 5 TON. The basis of payment is at the contract unit price for each ton.
8003: To provide access to the properties along Longfellow Avenue from Sta. 514+30 to ` z. 525+20 it was agreed tace Class M
concrete to get curing time down to 24 hours. This allowed access to properties in a li ore than 24/ ou)/.r�op• • fed to 3 to 4 days.

Change Order No. 1
7001 — 7005, 7007, 7008: Contract Unit Price.
7006: Includes a price increase from $41.00 to $47.00 per square foot.
8001: Unit Price of $1.00 per SY of Cold Weather Protection.
8002: Agreed Unit Price of $200 per TON for HMA Commercial Mix.
8003: Agreed Unit Price of $54.00 per SY for Driveway, P.C. Concrete, Class M, 6 In.
C-2 — Justification for cost(s)
7001-7005, 7007, 7008: The cost justification will be at the contract unit price as bid.
7006: The price increase for cast iron detectable warning panels is justified since it falls in the range of awarded contract prices for
detectable warnings. (Low of $15.00, High of $65.00)
8001: As stipulated in Iowa DOT Specification 2301.
8002: The IDOT Summary of Awarded Contract Prices, January 2012 through December 2012, shows an average price of $123.57 per
TON and a high price of $500.00 per TON. The unit price of $200.00 per TON is for a very low quantity and is being placed at multiple
locations. This price is reasonable considering the low quantity and the work involved installing the HMA.
8003: The IDOT Summary of Awarded Contract Prices, January 2012 through December 2012, does not have a price for PCC Driveway,
Class M but there is information on Class M relative to Class C in the PCC Paving bid items. For PCC Pavement, Class C, Class 3
Durability, 7 In. there was a 52% increase in average bid prices to go to Class M. For PCC Pavernent, Class C, Class 3 Durability, 8 In.
there was a 22% increase to go to Class M. The price of $54.00 per SY for PCC Driveway, Class M, 6 In. is a 26% increase over Class C.
The percent and price increase from Class C to Class M PCC Concrete are justified based on the increases found in the awarded contract
prices in the trailing 12 months.
No Adjustment for Working Days is Needed for this Change Order.
