Waltham, Massachusetts

For this project, APEX teamed with ECT2 / Haley & Aldrich of Portland, Maine in support of their project at the former Raytheon facility in Waltham, Massachusetts. ECT2 developed a synthetic media groundwater and vapor treatment system for the facility.

ECT2 / Haley & Aldrich provided an engineered solution in the form of process and instrument diagrams (P&IDs). This included the selection of process equipment, piping material and control valves. APEX then used the P&IDs to selected equipment and generate a drawing package suitable for contractor installation.


APEX performed the following services:

  • Piping general arrangement drawings
  • Piping plan drawings
  • Piping isometric drawings for piping 2" and larger
  • Review of ECT2 supplied major equipment specifications
  • Input / output list generated from mechanical P&IDs
  • Cable schedules and panel design
  • Design and specify variable frequency drives and electric power distribution
