BOD Room and Facility Expansion Planning


The original plan envisioned by Suburban Testing Labs (STL) involved the addition of a new Biochemical Oxygen Demand (BOD) room and a rough plan for specs for landlord fit out of the remaining available area. This was necessary in order to accommodate future growth by STL of the remaining floor space in their newly acquired building space.

During the discovery and evaluation phases of the project it was determined by Suburban that the original project scope needed to be modified to also include the relocation and expansion of an existing PREP laboratory. Certain other testing stations were identified as part of these expansion requirements.

espi worked with the Suburban Testing team to understand their processes and the relationship of the new BOD room and Prep laboratory to the other areas in their facility. A rough floor plan providing general plumbing, electrical feeds and demolition was established as part of STL’s expansion planning and landlord build out requirements.

Process flows with sample storage and testing equipment /workstations were determined. The team also established these for both the additional base and additional space while also accounting for future growth for a Prep and Gravimetric laboratory.

Following development of the floor space requirements and equipment locations and relocation of specified testing laboratories, the next phase of this project involved a more detailed plan for build out of the new bay and modification of the existing facility for the BOD room, Prep, Gravimetric lab and sample storage areas.

espi worked with the STL team to finalize these locations and requirements in order to make the modifications and improvements to the existing layout, thereby optimizing the available floor space and streamlining the process flow. Then, general RFP documentation for the required work including detailed equipment lists and a TO-BE layout of the targeted areas within the building were developed.


espi and the STL team located and laid out a proposed new BOD room and effectively used the remaining additional floor space for testing lab expansion. The potential growth affecting other laboratory tests performed in the various departments was considered. Based on this, STL executive management determined it was necessary to expand capacity and capabilities of the current PREP department.

During the course of this task it was necessary to revise the original project work scope envisioned by STL in order to achieve the targeted goals based on future growth expansion needs. This scope revision entailed:

  1. Relocation and expansion of the existing PREP laboratory.
  2. Placement of the BOD Room in the space occupied by the PREP lab.
  3. Modification to the existing storage room for use of selected tests.

STL’s executive management determined the growth that will be experienced with various tests performed in the PREP laboratory. Based on this, it was determined to relocate the current PREP lab to the newly expanded floor space. The proposed new location for this department was expanded. Certain tests presently done in PREP were allocated to other departments further increasing the capacity of this area and better utilizing the floor space.

Detailed Testing Equipment /Workstation lists including sizing requirements were established in each testing department including identification of support utilities. A proposed TO-BE layout including modifications to the existing operations and additional floor space was developed. The proposed layout accounted for the additional floor space and included changes to the existing operations in certain areas of the building, encompassing the various key testing applications and testing environment conditions.

espi also developed RFP documentation outlining the work scope necessary to make the required construction improvements and build out requirements to the building. This documentation was categorized by skill type and preferred sub-contractors were selected by STL executive management, competitive bid quotations.


As a result of this project, the STL and espi teams worked together to develop a detailed plan for the introduction a Biochemical Oxygen Demand Room and identified for use of the additional floor space. Modifications to the current laboratory departments were detailed and incorporated as part of the overall expansion plan. The RFP documentation reflecting the modifications and work scope requirements were developed for release to prospective contractors.

These detailed plans and documentation, when executed, will assist Suburban Testing in successfully attaining the improved utilization of both current and new floor space in their facility. The benefits will also contribute in streamlining the various testing processes and allowing them the ability to keep up with current demand and the opportunity to further expand based on future business growth.

As of this writing full construction was not completed. However, areas for expansion have been identified and documentation developed for this work. The benefits from these when fully executed will assist Suburban Testing in moving forward with their future expansion and build out of their facility to accommodate their projected growth.
