Projects for the residential, commercial, retail, dental, and medical sectors make up a large percentage of BnK Construction’s portfolio. The firm started its general contracting practice over 25 years ago. Since then, it has helped local and national brands conceptualize and construct spaces representing their brands and their core vision. Bunk Sandwiches, Dickey’s Barbecue Pit, Blue Olive, and 18/8 Men’s Salon are just some organizations that have relied on the firm’s efficient and high-performing delivery method. 

Another example of the company’s commercial construction work was completed for a Cold Stone Creamery restaurant. The construction of the restaurant space reflects the firm’s ability to deliver interior and exterior spaces that embody its client’s unique brand. The warm palette of beige serves as a soft canvas for the nostalgic and familiar colors of the store’s creations. Its contrasting lines of dark frames and metalworks hint at the ice cream parlor chain’s contrasting red and black branding. Its open layout promotes movement and provides a comfortable space for dining.

The firm’s portfolio highlights wineries, breweries, hotels, retail and grocery spaces, and single-family residences. It uses the latest construction and design technology to take on architecturally and structurally demanding projects. 

The firm’s Fresh Foods commercial project is among its most commended works. The company led the architecture and construction teams for the client’s Cannon Beach location. The client already worked with the company to complete the food brand’s Manzanita commercial center. Like the first design-build project, the new store was designed with customers in mind. Instead of just being a typical grocery store where people shop, it accommodated a coffee and soup bar where patrons could interact and spend time. The store also features stunning coastal views.

The 2020 Associated General Contractors Construction Safety Excellence Awards honored this Portland construction company.

For telecommunications company Verizon, the firm led the remodeling and construction of Verizon Wireless’s Murray Scholls Town Center. The project for the 1,123-square-foot space involved upgrading all its interior finishes to align the design and color palette with the brand’s signature style. Included in the upgrades are a brand-new ceiling grip, display cases, cabinets, carpets, and interior paint. A stock room and a restroom at the rear part of the store were also part of the work.

Since it launched its services over 25 years ago, Hammer & Hand has been delivering an award-winning construction practice to the region’s residential and commercial sectors. In addition to numerous Gold Nugget and Green awards for its single-family home projects, the firm’s work for the commercial sector has also earned several Outstanding Remodeling Achievement Awards in recent years. Many of the firm’s projects as a commercial general contractor are products of partnerships with leading designers and architects in the field. One example is the firm’s tenant improvement work for Danner’s Union Way location. 

The project, built for the Lacrosse Footwear brand, was a collaboration between the company and designers Michelle Jeresek and Brian Pietrowski. Set in earth tones and natural materials, one of the most interesting aspects of the build is its use of native wood, including western maple, which is all sourced from the Pacific Northwest.  Another highlight of the store’s interior is its living wall, where the Danner pops out of its green canvas. For the display sections, the firm used custom-milled brass shelving hardware. The best spot in the store is its custom madrone dressing room, which was inspired by a teardrop camping trailer.

Today, a number of organizations and publications have recognized the company’s contribution to shaping Oregon’s urban centers.  One of the firm’s most notable projects in Portland is the Pine Street Market. The work has been commended by the design and building community, and WestJet Magazine and Pine Street Market Press featured the project in recent years.

As a landmark commercial hub in the city, Pine Street Market accommodates restaurant spaces and high-tech and creative workspaces. The firm’s design-build nature allowed it to provide a full-service delivery method and to lead the project’s architectural and general contracting team.

One of its most iconic works can be found in Georgia.

This presented an exciting challenge in transforming the structure’s interior and exterior spaces since the site is a registered historic location and a landmark in Atlanta. The firm had to make sure that the sign remained operational and the wall’s stone-clad façade remained intact. Additional work on its exterior included structural support improvements, the installation of new bike racks, as well as a transformation of the Decatur and Edgewood sidewalks. The project also produced a 4,650-square-foot basement stock area and equipment rooms.

Ranking Methodology

To evaluate the performance of contractors, our methodology employs a systematic approach that considers various factors contributing to customer experience and satisfaction. We focused on assessing the commercial contractors in the Portland, Oregon area. The methodology involves assigning weightings to specific categories based on their significance in determining customer service quality. Here’s the breakdown of the categories and their respective weightings:

  • Average Customer Satisfaction (35%): This metric represents the average rating given by customers across the same review platforms as the Average Customer Satisfaction Score. A higher average rating indicates greater overall satisfaction with the service provided.
  • Service Rating Score (25%): We analyze the ratio of high (4-5 stars) to low (1-2 stars) ratings for each business across multiple review platforms: Google, Houzz, and Yelp. A higher percentage of positive reviews contributes to a higher score, reflecting better customer satisfaction.
  • Complaint Percentage (25%): We analyze the ratio of complaints to total reviews for each business. A lower complaints ratio indicates better service quality and results in a higher score.
  • Business Hours and Availability (10%): The operating hours of each business are assessed to gauge accessibility. Companies with extended operating hours are awarded a higher score, as they offer greater convenience to customers.
  • License Status (5%): We verify the licensing status of each contractor with their local licensing board to ensure legal compliance. Companies with valid licenses receive a higher score, reflecting professionalism and adherence to regulations.
  • Total Score: We determined the overall rating for every contractor by calculating a weighted average, with the category weight determining the amount the subscore contributed to the total score 

Additional Note: Service Rating Score, Average Customer Satisfaction, and Complaint Percentage are calculated with a Bayesian estimate to account for if the contractor has a low number of total reviews. A Bayesian average is a statistical method used to calculate the average of a set of data points while taking into account prior information or beliefs about the distribution of the data. It combines the observed data with a prior distribution to generate a more accurate estimate of the true average.
