PROCEDURE NO: CM 4.5
TITLE:
CONSTRUCTION RISK
ANALYSIS
DATE: 7/22/03
REVISION: 0
1. Policy:
To establish and incorporate Construction Risk Analysis procedures on projects
during the last stages of project design and before commencement of construction
that will reduce operational disruptions to Water/Waste Water related facilities during
construction.
For Planning/Design Risk Analysis, refer to SFPUC Project Operation Manual
Volume 2 Project Design Project Procedure No. PD 4.5 Engineering and Operations
Design Interface and Coordination.
2. Definitions:
Client Operations Representative (COR) – is a representative of the client [e.g.
Water Department or Water Pollution Control Department] whose main role is to
coordinate the process issues and concerns with other departments such as
engineering, construction and other agencies.
Risk Analysis Matrix (RAM) – is a report presented in a table format that summarizes
the major risks and/or potential hazards that could impact operations and
construction. The report also outlines contingency plans and responsible parties
during construction.
Planning/Design Risk Analysis – is the Risk Analysis performed during the Planning
and Design Phases of the project where most of the results noted in that analysis is
incorporated into the design.
3. Description:
•
Construction Risk Analysis procedures will seek to identify critical work scope
items that will need contingency planning during construction.
•
Construction Risk Analysis procedures will lead to fewer disruptions to normal
treatment plant/pump station operations.
•
Construction Risk Analysis will seek to identify Emergency Contact numbers
for the project in the event of an emergency.
CM Manual: Procedure CM 4.5, Rev. 0, Page 1 of 3
4. Responsibilities:
The Project Manager (PM) has the overall responsibility for the project work scope,
schedule and budget.
The Client Operations Representative (COR) will be the lead person to develop the
Risk Analysis Matrix.
The Project Engineer (PE) and the Resident Engineer (RE) will provide input to the
COR for the development of the Risk Analysis Matrix.
The PM will resolve and/or authorize the implementation of the recommendation of
the RAM. The RE and COR will be jointly responsible for the implementation during
construction.
5. Implementation:
The Construction Risk Analysis should be performed on any elements of the design
and construction that will impact the normal operation of the facilities, including
disruption to: electrical power, controls, telecommunications, I&C systems, flows,
box levels pumping, dewatering, gate isolation, site access, planned shutdowns,
problems at other points in the system, etc.
During the 95% Detailed Design of all process related projects, the COR, along with
the PE, Design Team and RE, shall identify parts of the project that may adversely
affect the operations of the facilities or the construction process.
The COR will prepare a contingency plan to deal with the identified items, and shall
present the plan at the final design review meeting and subsequently at the preconstruction meeting.
A Contingency plan is developed to:
•
Identify all possible related hazards, develop available options and alternatives,
establish planned procedures, and identify key elements that need to be in place
before a disruption is allowed.
•
Provide long term planning for Operations to avoid scheduling events that will
interfere with operations or maintenance of facilities.
•
Inform related Utilities of possible disruptions.
•
Identify all possible resources needed in the event of an emergency and have
contact numbers handy.
•
Identify regulatory bodies such as Regional Water Quality Districts who may levy
fines or sanctions or stop work in case of violations.
•
Identify regional customers and other interested parties who may be affected by
an interruption of flow.
After receiving PM’s approval of a contingency plan, the PE will incorporate key
requirements into the plans and specifications of the construction contract
documents to warn Contractors on what they need to be aware of and what steps
they need to take to allow the contingency plan to take place.
CM Manual: Procedure CM 4.5, Rev. 0, Page 2 of 3
For complex projects, the contingency plans need to be discussed during the preconstruction meeting, and a subsequent meeting to discuss the details of the plans
that might be necessary to be scheduled.
A generic list of items to be considered in the Construction Risk Analysis (will be
revised for each project) could include:
•
Will work impact access to facilities?
•
How will chemical deliveries and dumpster pickups be maintained?
•
How will security be maintained?
•
Can equipment located in or near the construction area be maintained?
•
Will the work impact the ability to maintain normal operations?
•
Does the work expose “dry” areas to uncontrolled flows?
•
When lighting is interrupted for construction will temporary lighting have to be
provided?
•
When the ventilation system operations are interrupted for construction will odors
result?
•
What utilities (water, air instrument communications, power, etc) will be affected?
•
Is phone service affected by power outages?
•
What happens if utilities are hit by construction operations (e.g. backhoe screws
electrical conduit)?
•
What special operating conditions are required to isolate the work?
•
How is the construction process impacted if it rains?
•
How would construction and process be impacted in the event of system wide
power outage?
•
How accurate are the As-built drawings?
•
How will Supervisory Control and Data Acquisition (SCADA) be affected and
what are the contingency measures?
•
How will the site be affected by storm drainage (Hill areas can cause mud slide)?
At the beginning of construction, the team, including Operations, Construction
Management and Contractor, shall convene to discuss the above and add items as
required that pertain to the specific project.
A typical Construction Risk Analysis Matrix (RAM) is shown in Attachment 1.
