Operatine Rights
Page 4
PSE facilities resulting from commencement of construction prior to acquisition of all identified
necessary operating rights.
Construction Work Schedule
The work will be performed in accordance with the following Work Schedule, unless this
schedule is revised by mutual agreement of the City and PSE or circumstances beyond the
reasonable control of the City and/or PSE preclude such performance.
Installation of ducts and vaults: Construction to start in summer 2010.
Work Schedule Restrictions: None
Construction Cost Estimate
The estimated costs to perform the Construction Work and the allocation of costs between the
parties are presented in the attached Construction Costs Estimate Summary. These estimated
costs are valid for 90 days from the date on the Construction Costs Estimate Summary page. If
this Project Plan and the Construction Agreement are not fully executed within 90 days, the
estimated cost is subject to revision.
Proiect Assumptions
The project design, construction plans and cost estimates are based on and reflect the following
assumptions. Construction conditions that are not consistent with these assumptions may result
in a request for change or an equitable adjustment to project compensation under Section 6 of the
Construction Agreement.
Cost Assumptions
1. The Construction Work will be performed in accordance with the Construction Work
Schedule.
2. PSE's Project Manager will accept or reject (with written justification) the duct and vault
installation work performed by the City within five (5) business days notice of completion
from the City. In the event PSE rejects any of the ducts or vaults (with reasonable written
justification), the City will perform the necessary remedial work. The City will then re-
notify PSE and PSE shall have five (5) business days to accept or reject the remedial work.
3. All PSE cables can be pulled through the ducts and vaults system to be used for the
Conversion Project utilizing normal cable pulling techniques.
4. A City Street Use permit is the only permit necessary for PSE to perform its work for this
Conversion Project and will be issued within two (2) weeks of PSE submitting a complete
permit application (including any supporting documentation reasonably required by the
City). There will be no charge for the permit or inspection fees.
5. The estimated daily productivity rate for PSE duct and vault installation is based on an
assumed availability of 300 feet of trench per working day. The daily productivity rate is
City of Tukwila
Southcenter Parkway Extension Underground Conversion
105052358
Page 5
227
228
trench per working day. The daily productivity rate is used to calculate the number of days a
PSE provided Inspector will be required. During construction, the Inspector will be
scheduled in full day increments and in one continuous effort. Changes to a continuous
schedule require a minimum of five days advance notice. Inspector time will be charged to
the project for days that are less than the five days notice. Actual Inspector time will be
trued -up to the estimated productivity rate by Change Order. Since additional PSE facilities
beyond those allowed by Schedule 74 will be installed in a common trench, total Inspector
time for the project will be allocated 20% to the Schedule 74 contract and 80% to the other
portions of the project, within the conversion area.
6. This proposal assumes the use of two flaggers, basic signage and simple channelization.
Additional traffic control measures are not included.
7. Work to be performed by PSE does not include installation and/or removal of Temporary
Service facilities at the request of others during construction.
8. All cut -over and transfer work will be completed during regular working hours.
9. Installation of protective bollards may be necessary at some locations and may not be
included in the project design. In the event unplanned bollards are required, the associated
installation cost will be a shared cost.
10. Where noted on the plans, existing ducts, either empty or currently used, are to be utilized for
new cables. The Construction Costs Estimate assumes that such ducts are in place and
available for use to pull in new cables using the same equipment and effort as newly installed
ducts.
11. The Construction Costs Estimate assumes that guy anchors are installed prior to the
installation of the ducts in the area. Installation of guy anchors in the same area as newly
installed conduits may be subject to Change Order.
12. The labor rate assumption used in the Cost Estimate is based on 2009 rates. Any work
performed on this project during 2010 is subject to Change Order based on 2010 labor rates.
Schedule
1. There will be a total of two (2) PSE crew mobilizations as follows: i) one mobilization of an
underground line crew for installation of underground conductors and equipment; and ii) one
mobilization of an overhead line crew for removal of the existing overhead facilities. Once
mobilized PSE crews will have continuous productive work until all PSE Construction Work
is complete.
2. All PSE Construction Work will be performed during regular working hours from 7:00 AM
to 10:00 PM weekdays and 8:00 AM to 9:00 PM weekends, excluding holidays, and
excluding the intersection of S 180 St and Southcenter Parkway. In the event that lane
closures are necessary for performance of work, P SE shall be limited to working during
hours as directed by City. PSE will provide a weekly construction schedule during the
weekly meeting. Once approved, PSE crews will be allowed to complete the work as
scheduled, without changes and work stoppages caused by other construction activities.

3. Work requiring scheduled interruption of electric service (cut -overs and transfers) will be
performed during the working hours specified in Schedule Assumption #2 above, and will be
scheduled with at least two (2) business days notice. PSE will notify customers of scheduled
service interruptions.

charges, will apply to perfouuiance of this work. The individual addresses to be converted are:
18800 Southcenter Pkwy. (M &P Company property)
**18010 Southcenter Pkwy. (Segale Properties /law office property)
Cut -overs and Transfers
PSE customers within the Conversion Area will experience interruption of electric service during
performance of the Construction Work when transferring system and customer loads from the
overhead distribution system to the Underground Distribution System. PSE will notify
customers at least two (2) business days in advance of expected service interruptions. Customers
may request that cut -over and transfer work affecting their service be performed outside the
regular working hours listed above subject to the customer's written agreement to reimburse PSE
for the additional cost (at overtime rates) to perform such work outside the regular working
hours.
New Service
Connection of new or increased load for City facilities (such as new traffic signals) under terms
of PSE Tariff Schedule 85 will be addressed on a separate work order and work sketch.
Additional costs may apply and will be quoted separately.
PSE Desien Construction Standards
This Conversion Project has been designed and will be constructed in accordance with PSE
design and construction standards in effect as of the date of this Project Plan. PSE standards
applicable to Construction Work to be perfouiied by the City have been provided to the City in
