Page | 5

2.3 Communication methods:

Howard S. Wright will provide an email notification monthly, at a minimum, summarizing the

upcoming activities and associated impacts. In the event of any unplanned, unusual or

disruptive activities required for the project, the Construction Point of Contact will make their

best effort to provide SDOT and the members of the Neighborhood Notification List with a

Construction Notification indicating nature of activity, location, and duration at least 10

business days prior to the start of activity. Activities that may require notification include

street/sidewalk closure, associated detours, oversize deliveries, excessive hauling, noise and

work hour variations, and utility interruptions.

2.4 Notification timing & tracking:

Contacts on the Construction Notification List will be notified of upcoming activities weekly via

email, in addition to the updates concerning unforeseen disruptive activities. Notice will also be

given to SDOT, when required, regarding street use and right of way impacts (a minimum of 10

business days prior to the start of these activities).

2.5 Construction Project and Known Special Events in the Vicinity

Construction Projects:

• Sound Transit – Completing 2020

Special Events:

• University District Street Fair – Occurs May 21st – 22nd, 2017

o This event occurs on the weekend and is several blocks away. Special care will be

taken so as not to schedule impactful work during this weekend.

3. Construction Noise and Sensitive Receivers

3.1 Construction Hours

The majority of construction activities will be limited to standard construction hours between 7

a.m. and 6 p.m. on non-holiday weekdays. Construction workers may arrive at the site prior to

standard start times; however, they will be instructed during their site orientation that loud

talking and noisy set-up activity will be prohibited prior to 7 a.m. on weekdays and 9 a.m. on

Saturdays, unless a noise variance has been coordinated with the City of Seattle. Work is not to

be performed on Sundays or construction observed holidays. Any equipment warm-up prior to

standard times or times coordinated through a noise variance with the City of Seattle will be

such as to limit disturbance to neighbors.

Page | 6

HSW anticipates that some evening and Saturday work will be required using smaller crews

between the hours of 6 p.m. and 10 p.m. on non-holiday weekdays and between 9 a.m. and 6

p.m. on Saturdays. Work performed at this time will generate smaller amounts of noise and will

fall within the limits of the City of Seattle noise ordinance. In addition:

I. Work that is scheduled to take place during evenings and Saturdays will help

significantly reduce the overall length of the schedule.

II. Work is not expected to occur on construction holidays, which are defined as: New

Year’s Day, Memorial Day, Fourth of July, Labor Day, Thanksgiving Day, day after

Thanksgiving Day, and Christmas Day.

A Howard S. Wright (HSW) representative will be onsite at all times during construction

activities and will respond to any issues that may arise.

3.2 High noise-generating activities

Activities that will potentially generate unusual amounts of noise will be as follows:

• Demolition of existing structure

• Chipping, sawing and removal of site concrete and asphalt

• Drilling for installation of shoring system

• Shotcrete activities

• Crane setup & dismantle

• Structural steel erection

• Setup for concrete pouring operations

• Metal Stud Framing Operations

3.3 Noise-sensitive receivers

The following are noise-sensitive receivers:

• Marriott Residence Inn

• CorePower Yoga

• Hotel Deca

• 32 Good Reason – Family, Cosmetic & Implant Dentistry

• U District Family Dentistry – Andy Nelson

• The Collegiana – UW Medicine

Page | 7

3.4 Construction noise management

HSW will use the following techniques to minimize construction noise and vibration:

Timing Restrictions:

i. Most activities will be limited to standard construction hours, which are 7 a.m. to 6

p.m. on non-holiday weekdays.

ii. Impact types of equipment such as, pavement breakers, jackhammers, powder-

actuated tools and other impulse noise sources will only be used between 8 a.m.

and 5 p.m. weekdays and 9 a.m. and 5 p.m. on Saturday.

Noise Reduction Construction Technologies:

i. “Ambient Sensitive Broadband Alarms” for all equipment requiring alarms will be

used. These devices use a motion sensor to activate the back-up alarm; otherwise

the alarms operate at a much-reduced level.

ii. Back-up alarms will not be allowed to operate from 10 p.m. to 7 a.m. on weekdays

and 10 p.m. to 9 a.m. on Saturdays.

Process Modifications:

i. Reduce truck noise and audible backup alarms by using 12th Ave NE for trucking

activities. 12th Ave NE is the least busy of the streets bordering the jobsite.

ii. Loud talking or other miscellaneous noisy activities are prohibited before 7 a.m. and

after 10 p.m. on weekdays and before 9 a.m. and after 6 p.m. on Saturdays

iii. Concrete truck staging will be done off-site to minimize the impact of street-level

truck traffic. The location of a staging area will depend on awarded Subcontractor’s

coordinated staging plan with the Seattle Department of Transportation.

iv. Pre-fabrication of construction assemblies at off-site locations will minimize on-site

manpower and noisy activity. For staging locations and trucking routes, comment

(iii) above applies.

v. The concrete pumping station and concrete deliveries will be located on 12th Ave NE.

The material and personnel lift will also be located on 12th Ave NE.

vi. A compliance statement for this Construction Management Plan (CMP) will be

included in all subcontracts for this project. HSW is responsible for all subcontractor

adherence to this CMP.

vii. During demolition, excavation and construction, debris and exposed areas will be

sprinkled with water as necessary to control dust.

Page | 8

viii. To aid in maintaining air quality, electrically operated small tools will be used in

place of gas powered small tools wherever feasible. HSW will make every effort to

manage the work to avoid noise variances, and any street closures beyond those

described in other sections of this plan. However, as is typical for urban construction

projects, there will be times when such variances and additional street closures will

be required. Neighbors will be notified by email as describes previously in advance

of any work requiring noise variances, and street closures beyond those described

elsewhere in this plan.

Haul Route Narrative:

Truck and Trailer combinations will be used for disposing of demolition debris and site clearing

Demolition of the existing foundations is scheduled to begin approximately 04/03/2107 and

end 04/28/2017. There will be about 3 trucks per day hauling the demolition debris.

Shoring & Mass excavation will follow, scheduled to begin approximately 05/02/2017 and end

07/10/2017. During this time, Approximately 17,500 CY of soil will be exported. 40 loads will be

exported daily at a frequency of 1 truck per 6-8 minutes. Trucks will be loaded on site from an

excavator, entering the site off of 12th Ave NE Southbound and exiting the site down 12th Ave

Page | 12

NE southbound. Flaggers will be utilized to facilitate trucks crossing 45th Ave NE into the loading

zone on 12th Ave NE. Construction loading/unloading will occur on hardscape to minimize risk

of tracking debris onto adjoining streets as well utilization of street sweepers throughout the

day as needed. The trucking operation will take place between the hours of 7:00 am and 6:00

pm.

Structural steel erection will occur on a continuous basis beginning approximately 08/01/2017

and ending 11/03/2017. It is anticipated that between 2 and 3 40’ flatbed semi delivery trucks

will be used a day during the peak of structural steel erection.

Concrete pumping activities will occur approximately once a week beginning roughly

09/01/2017 and ending 12/08/2017. It is anticipated that between 10 and 12 concrete mixer

trucks will be used to pour the concrete fill on metal deck at the peak of construction.

All deliveries will be received on 12th Ave NE Southbound lane. Street use permits will be in

place to adjust the 12th Ave. NE traffic lanes during working hours (7am to 6pm). Including

closing the west sidewalk and parking lane on 12th Ave. NE.

Onsite supervision will be in constant communication with all truck drivers to ensure proper

spacing is occurring during demolition, mass excavation, concrete pours, structural steel

erection and any misc. deliveries throughout the project life cycle.

The contractor acknowledges the following:

o Any changes to routing will need prior approval

o All oversize loads shall have separate approval for each movement

o No truck queuing or staging allowed at or in the vicinity of the job site, including I-5

o All necessary SDOT and DPD permits shall be in place prior to any trucking activity
