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 youin 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 haveon students and faculty? How readily does thatbecome 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 betweensystems 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.NYCSCA BUILDING SYSTEMS COMMISSIONING



Commissioning Scope

Commissioning is a flexible process configured to

match each individual project.

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




Implementing Commissioning

Specification – Commissioning Administrator (Division 13000 or 18000)

– Mechanical Commissioning Support Responsibilities (Division 15000) – Electrical Commissioning Support Responsibilities (Division 16000)
