How SPEC develops Design/Build Projects (Part 1 of 3)

Part I
SPEC’s approach to Design/Build projects is unique, even within the design/build community.  Since we are frequently asked to clarify what our approach encompasses, we thought the topic was worth further explanation here.

Because SPEC’s projects and clients are all technology based, the first step in a Design/Build project is the development of a Scope Study.  This study allows us to clarify with the client all important factors, such as major pieces of equipment, owner’s budget, and process requirements early so that everyone is on the same page before a significant amount of the design budget is expended.  This approach allows us to confirm key design points early on, so minimal re-design or engineering is required.

Scope Study
The scope of work and deliverables for the Design/Build project is first defined in the Scope Study.  The development of this study starts with a series of preliminary engineering meetings.  These meetings are a knowledge transfer from the client to the engineers and can include drawings or other process documents (Standard Operating Procedures, quality control tests, etc), which have already been created by the client, as well as a discussion of the process requirements, and any budget requirements.

Scope Study Deliverables

  • Site Review

SPEC’s architect performs a site review of the current or proposed location that would include inspection of all existing conditions and potential flexibility for additional site changes.   This would include an investigation of site suitability for construction and any other issues that would affect construction costs.

  • Manufacturing Process Review

The process engineering team reviews all current manufacturing operations and proposed changes/expansions.   From this effort a material & energy balance, a Process Flow Diagram (PFD) and a major process equipment list, are developed and estimated floor area requirements are determined.

  • Utilities Requirements

SPEC's discipline engineers (Electrical, Piping, and Mechanical) will review the PFD’s energy and material balance and determine which utilities will need to added / modified for the new process.

  • Architectural Review

The architect will review the client’s building for code and egress issues.  A preliminary code review will be conducted based on the client’s site usage and hazardous material storage requirements.

  • Process Narrative

A written process narrative showing an understanding of the process and its requirements with SPEC’s proposed solution and scope of work.

  • Estimate

SPEC’s construction department will develop a project budget as a factored estimate using the process equipment list, utilities requirements and project estimated floor area.
