INFORMATIONAL MEMORANDUM
TO: Mayor Haggerton
Transportation Committee
FROM: Bob Giberson, Public Works Directo
BY: Grant Griffin, Senior Engineer
DATE: November 21, 2014
SUBJECT: Thorndvke Safe Routes to School Project
Project No. 91210302, Contract No. 13-160
Winter Project Shutdown
ISSUE
Report the winter shutdown of the Thorndyke Safe Routes to School Construction Project.
BACKGROUND
A call for bids was advertised on May 8 and 15, 2014 and three bids were opened on May 29,
2014. The lowest bidder was Road Construction Northwest, Inc. (RCNW) with a bid of
$1,136,256.00 and the contract was awarded on June 23, 2014. RCNW requested and was
granted a September 14, 2014 Notice to Proceed date due to their work load. While some
preliminary work and detour set-up was completed, construction did not start in earnest until
October 23, 2014, after which they diligently pursued the work.
DISCUSSION
RCNW finished all of the underground storm drainage and utility work by November 14, 2014. At
this point they hesitated to remove the existing pavement with the threat of November
rainstorms on a jobsite with such steep grades. A request for a winter shutdown was sent on
November 11, 2014 and after review by the City, was granted. Because of the late construction
start, the City will bear no costs associated with the project shutdown, site maintenance, or
resumption of construction in the Spring. The construction shutdown is expected to last from
November 14, 2014 to no earlier than March 1, 2014 and no later than April 1, 2014.
The City has required that RCNW maintain the construction zone and ensure that the site is in
satisfactory condition during the construction shutdown.
FINANCIAL IMPACT
There is no financial impact as outlined in the attached Project Serial Letter 03.
RECOMMENDATION
Information only.

SUBJ: Project Winter Shutdown Request
Gentlemen:
Per our conversations with City of Tukwila Senior Inspector Scott Moore this past week, Road
Construction Northwest Inc. (RCNW) concurs that demolishing and removing the existing
asphalt roadway; and exposing the subgrade to the weather elements this time of year would not
be in the best interest of the project. As we discussed at our weekly construction meeting last
Thursday, November 6th; after the curb & gutter is installed on the south side, we would need a
full week of dry weather to remove the existing pavement, excavate to subgrade, place crushed
rock and prepare for asphalt paving. We are getting to the time of year where it is very difficult
to get acceptable temperatures and dry weather conditions in order to schedule paving with
Lakeside Industries. Also they close their asphalt plants for annual maintenance this time of
year.
We believe that finishing the remaining storm drainage work and water services work this week
would be a good stopping point for a project winter shutdown; with minimal impacts to the
project and inconveniences to the local residents. We will hot -mix asphalt patch all roadway
trench crossings, install BMP erosion control devices, restore driveway access, remove signs &
traffic control devices and demobilize. RCNW will continue to monitor and maintain erosion
control devices, and will stay in contact with City Senior Inspector Scott Moore on any other
needs in the field.
RCNW requests that contract calendar days be suspended at the end of this week, Friday,
November 14th for contract work; and that we be allowed to work next week on HMA trench
patching, site restoration and preparation for winter shutdown as non - contract days.

We will stay in contact with KPG and the City of Tukwila to coordinate an appropriate restart
date next Spring 2015, upon which we will present a revised schedule to complete the balance of
the Contract Work. Your cooperation and assistance in this matter is appreciated. Should you
have any questions or concerns, please contact me at (425) 254-9999 x-22.
Very truly yours,
Gordon Lee
Project Manager

Project — Thorndyke Safe Routes to School
City Project No.: 91210302
Dear Gordon,
This letter is in response to RCNW's letter titled Project Winter Shutdown and dated November 11,
2014. In that letter RCNW requests a p ject suspension beginning 11/14/14 and ending in the Spring of
2015 due to unsuitable weather for the remaining work. After review, the City agrees to the suspension
proposal per 1-08.6 of the 2014 WSDOT standard specifications with the stipulations specified below.
RCNW shall bear all additional costs necessary to bring the site to a satisfactory condition suitable for
suspension as determined by the City. Additionally, all costs to demobilize, remobilize, maintain the
site's erosion control, maintain the site's roadway surfaces, and maintain the site's walking surfaces
shall be borne exclusively by RCNW. RCNW will remove all equipment from the site at a date no later
than 12/15/14. RCNW will visit the site and provide the Engineer with a brief written report cataloguing
the site's condition and documenting any maintenance performed at an interval not less than once per
week. Any increase in product or labor costs due to the suspension is the sole responsibility of RCNW.
The list above is not exclusive; in general, all costs associated with the suspension are the responsibility
of RCNW.
The project will be suspended from 11/14/14 to a date not earlier than 3/1/15 and not later than
4/1/15, depending on predicted weather and as determined by the Engineer.
Sincerely,
Nathan Monroe PE
