Kenmore Aero Services Terminal Design

A flight terminal was created by renovating a small, 2-story plane hangar at the Kenmore Aero Services Boeing lease lot in Seattle. The project required compliance with zoning, existing building and fire codes, and FAA regulations. It was a change of use so energy and structural renovations, as well as zoning compliance had significant impacts on the project. Engineering consultants, including traffic planning and Geotech, were brought in for the planning and design phases.

Digital Controls, Inc Facility Planning

Digital Controls, in Renton Washington, makes sensors for underground boring equipment. They occupied about half of the 1-story building, and wanted to expand into the whole floor. In pre-design Hazelrigs Architecture prepared an as-built layout, and developed a work-flow analysis working intensively with each of nine groups. From those, a detailed facility program with a three-year forward look, was developed. Equipment was documented and clearances for electromagnetic pieces established. Working with eight functional groups, a space plan was developed, iteratively reviewing each groups desired layouts with the adjacent groups an optimum layout.

Dog Kennel Code Research

A dog kennel owner in rural King County Washington had begun construction without a permit, so needed an “Already Built Construction” permit. Because some of the construction didn’t meet code, research was required to justify the built condition. One key condition was the width of a walkway in a dog housing building that was less than the building code allowed. Nine different codes were researched to find a basis to justify the width. Of the nine codes, five provided a reasonable basis for allowing the walkway width; 2018 IBC, NFPA 101-18 Life Safety Code, NFPA 150-90 Standard on Fire and Life Safety in Animal Housing Facilities, OSHA Standards – 29 CR, and WAC 296-800, 1910. A detailed documentation of code references and text, and commentary showing how each reference supported the walkway width, was prepared for the county to review.

Permit Facilitation

Overlake School Conditional Use Permit

The Overlake School in Redmond Washington is a private 5th through 12th school in rural Redmond Washington. They were planning new buildings, fields, parking lots, and road improvements throughout the 76 acre site. The King County permitting department required a Conditional Use Permit that encompassed all the foreseeable projects on campus forward looking for five-years. The campus was constrained by critical areas throughout the site, imposing building setbacks that determined where the buildings and site developments could be placed.

Hazelrigs Architecture assisted the school’s owner’s rep, Alliance Construction Management, to create the Conditional Use Permit application, shepherding it through the King County permitting department. The planning process began in 2013 and the CUP was approved in 2018.

Overlake School New Buildings Permitting Management

The Overlake School in Redmond Washington is a private 5th through 12th school in rural Redmond Washington. They were building two new buildings that had been designed by Mithun Architects in Seattle. Hazelrigs Architecture assisted the school’s owner’s rep, Alliance Construction Management, for permit submittal through permit approval. Permit were building, demolition, grading, health, critical areas, and a campus-wide septic upgrade permit. They worked with the septic designer to create a campus-wide system plan, and managed the state permitting. Temporary and permanent modular classrooms had separate permits. The Conditional Use Permit had strict dates to meet for permit submittal, issuance, and closeout. Permitting took a full year to complete.

Dog Kennel ABC Building Permit

A dog kennel owner in rural King County had begun construction of their kennel facilities and were told to stop work and get a building permit. This required an Already Built Construction (ABC) permit. Two new buildings were modified shipping containers, so they needed energy upgrades, structural reinforcing for openings that had been cut into the sides, and proper foundations.The owner needed a permit for site clearing done requiring civil design. The permit application included Health Department requirements for a kennel permit. The project was on a well, so the King County Health Department in charge of well water was involved. The site had critical area wetlands, so required building setbacks to be determined. A pole barn had been converted to kennel space which was a change of use that triggered additional upgrades. Zoning requirements had to be met. King County had issued violation notices which had to be resolved.

Hazelrigs Architecture worked with the County to work through these issues and put the project on course to get required permits.

Landlord Facility Design

Kennedy Building Vanilla Shell Design

The Kennedy Building in the University District of Seattle was a residence for students with commercial retail space on the street level. Hazelrigs Architecture provided BOMA calcs for the commercial space as well as several permit and reconfiguration projects.

For one project Hazelrigs Architecture prepared permit and design documents for the landlord, UDR, for a commercial tenant in a generic “vanilla” condition. This allowed UDR to build-out the scope of the project that they were responsible for, and allow the tenant scope to be in a separate permit.

Bloodworks BOMA Calcs

Bloodworks’ headquarters in Seattle is a 10-story 1950’s building in an iconic Brutalist style. They wanted to understand the marketability of the building, so asked for a Building Operations and Management Association (BOMA) leasing measurement of the building. The 10-stories are comprised of 2 parking levels and 7 office space levels, and one mid-building mechanical level. The calculation was based on the ANSI/BOMA Z65.1-2017, Method B Standard.

These areas were the main floor lobby, each floor’s waiting rooms, the corridors, restrooms, and elevators. The refresh included new paint, carpet and tile floors, waiting room furniture, new plant pots, art, and signage.
