ENVIRONMENTAL EVALUATIONS

Goal – avoid, minimize and mitigate/address potential project impacts and

Level-I contamination assessment;

Re-evaluating the site prior to replacements/replacements

Advantages Disadvantages

PCCP Durability and competitive prices for large diameter Unit weight per foot is the highest of alternatives.Corrosion control measures will be required

Steel Pipe Competitive price for large diameter pipes Lighter than concrete pipes

Installation of pipes will be new experience for local contractors. Corrosion control measures will be required

FRP Excellent corrosion resistance Does agency have experience and familiarity with this pipe

DIPFlexibility for future connectionsRelatively easy to install because of mechanical/push‐on joints

Corrosion control measures will be required

HDPE Leak resistance over PCCP due to quantity of joints & more leak proof joints

Longer trenches (access pits/shafts) to be opened at a timeWork zone/lay down area requirements

PROCUREMENT METHODS EVALUATION

PROGRESSIVE DESIGN BUILD

Procurement process in a short timeframe

Project can be implemented in phases

Maximizes owner flexibility

Initially cost for construction is not known

Cost is determined through combination of

negotiated and competitive processes

PROCUREMENT METHODS EVALUATION

CONSTRUCTION MANAGER AT RISK (CMR)

CMR handles some aspects of design

Designer and CMR hold separate contracts with owner;

CMR contracts directly with trades and takes on

“performance risk”

Overlapping design and construction

Professional management to an owner whose

organization may not have capabilities

Facilitates phased construction

Constructability and speed of implementation

Typically multi-step procurement process

Owner transfer of responsibility; DB entity is liable

for design and construction

Overlapping design (~30%) and construction
