Brown and Caldwell과 Poole & Kent 설계·시공팀은 최근 아메리카 설계·시공기관(DBIA)로부터 수여받은 자사의 첫 수상을 축하하기 위해 마이애미데이드 상하수도부와 협력했다고 발표했다.

마이애미데이트의 혁신적인 열병합(co-generation) 시설 향상 프로젝트는 설계·시공 프로젝트 전달 방식에서의 모범적인 협력과 통합 덕에 DBIA의 상하수 카테고리에서 매우 의미있게 여겨진다.

Brown and Caldwell은 설계·시공 파트너인 Poole & Kent와 마찬가지로 기존 마이애미데이드의 열병합 시스템을 최첨단 장비로 교체했으며, 이를 통해 주는 추가적인 대기오염 배출 없이 전기 용량을 3배 가까이 생산할 수 있게 됐다.

 

 

 

The Brown and Caldwell/Poole & Kent design-build team recently announced that it has joined Miami-Dade Water and Sewer Department to celebrate its first award from the Design-Build Institute of America (DBIA), Florida Region.

 

Miami-Dade's innovative co-generation facility improvements project at the South District Wastewater Treatment Plant is being recognized in DBIA's Water/Wastewater category for exemplary collaboration and integration in the design-build project delivery method.

 

Brown and Caldwell, along with its design-build partner Poole & Kent, replaced the department's existing co-generation system with state-of-the-art equipment that generates almost three times the amount of electrical capacity without discharging additional air pollutants.

 

This is one of the first co-generation systems of this size (8 Mw) that is capable of using three different types of fuel feedstocks (digester, landfill and natural gas) in an infinitely variable mix. The project was completed on schedule and within budget, providing about $965,000 in electrical cost savings to the district.

 

In 2011, Miami-Dade discovered that methane gas produced at the landfill adjacent to its South District facility, coupled with digester gas produced within the plant (and natural gas when required), could significantly cut back the amount of electric power imported from the grid, reducing the facility's reliance on fossil-fuel-produced electricity.

 

The department opted for the design-build delivery method to tap into the expected economic benefits quickly, while avoiding its continued use of imported electrical power and to meet the requirements of an imminent consent decree.

 

The Brown and Caldwell team collaborated to design and build this complex and ambitious project without interrupting service. Keeping the facility online was imperative because the plant used its existing co-generation units to maintain heat in the digesters.

 

The company was ideally suited to partner with Poole & Kent because of its design-build experience and long-standing ties. This relationship fostered an effective partnership and collaborative mindset to execute a project with significant scheduling, technical and safety challenges.

 

Brown and Caldwell reviewed the design criteria, provided innovative Value Engineering ideas and developed a Preliminary Design Development Report, which became the basis of design throughout the construction period.
