Quality Construction

If you could improve the total quality of your schools and facilities without extra costs, would you?

How much do Job Site Construction problems cost you in delays ?

Do you see a deviation in actual installation vs. design specifications? What is the outcome on your costs, schedule, performance and compliance?

What impact does a poorly performing building have on students and faculty? How readily does that become your problem?

What should the NYCSCA be considering?


A Trained Eye on Implementation

Do hard deadlines for School openings leave your projects with

gaping holes?!?

Non-Compliance of School HVAC Systems

Months or years of continued costly fixes

Improper installation

Unseen or mis-evaluated design issues

Poor air quality

Misdirected HVAC facility operations

Lack of proper perspective and understanding of the finished project

Under the gun…………………$...$$....$$$$


Overview of the Commissioning

Process

Commissioning is the administrative act of:

Documentation of NYCSCA Performance Requirements

Evaluation and Documentation of Design Basis and

Contract Drawings

Verifying and Documentation of system installation.

Verifying and Documentation of Equipment Start Up

Verifying and Documentation of Functional performance.

Verifying and Documentation of interactions between

systems and subsystems

Training of Operations and Maintenance.

Commissioning is an Administrative Plan with components customized for

each project to match the requirements of that project.


Commissioning Scope

Commissioning is a flexible process configured to

match each individual project.

1 • Assist Design team in developing documents that are:

• accurately reflecting Owner’s functional needs

• operable, commissionable and maintainable

• clearly communicate to the Contracts their

obligations to participate in and support the

commissioning process

• DPC process involves:

• Development of the owners design intent

• Commissioning Reviews of Design Documents

• Development of Commissioning Specifications

Benefits of Commissioning

Improved Contract Enforcement

Improved Quality of Documentation

Reduced O & M Costs

Improved System Performance

Improved School Comfort

Reduced Liability & Warranty Claims

Improved I.A.Q. (Indoor Air Quality)

Future Expansion or Renovation Made Easier

Greater Faculty and Student Satisfaction


Commissioning Costs

100,000 sq. ft. School

$4,000,000 HVAC Design and Construction Costs

Estimated 250 Ton HVAC System

Commissioning Cost

2% - 2.5% of HVAC Construction Cost

$80,000 - $100,000

Traditionally included in HVAC Cost

Final cost will depend on the detail of the scope of work

Average cost of commissioning is approximately

2 to 3 times the test and balance costs.

COST EXAMPLE


Minimum Costs of Not Commissioning

First Year Problem Detection and Solutions Operational problems not discovered at start up

30% of one operator

Second Year Problem Detection and Solutions Operation problems not discovered at start up

15% of one operator

Out of Warranty Expense Repair of items not discovered during the 1st year

Early repair due to incorrect operation

Early repair due to incorrect maintenance

Energy Inefficiency Lack of Calibration & Tuning

Lack of Proper Operation
