TESTIMONY OF KENNETH T. KOSTAL Ql. Please state your full name and place of employment for the record.

Al. Kenneth Thomas Kostal, Sargent & Lundy (S&L), 55 East Monroe Street, Chicago, Illinois.

Q2. Please describe your educational background and work experience.

A2. I graduated from the University of Illinois in 1965 with a BA in Architectural Engineering and in 1967 with an MS in Architectural Engineering. I have 20 years of experience in the field of civil engineering which includes civil / structural /

architectural engineering and design work for fossil and nuclear power plants. My assignments have included 14 units with a total capacity in excess of 10,000 megawatts. I have also been involved in numerous studies. In addition, as the 8609170209 e60716 PDR ADOCK 05000456 T PDR

1 Structural Project Engineer and Senior Structural Project Engineer on Braidwood, I commented on various specifications including Specification L-2790, Electrical Installation Work. Prior to joining S&L in 1967, I was engaged by the University of Illitiois as an instructor in structural design and as an engineer responsible for structural design and construction drawings for light office buildings. I am a registered professional engineer in 31 states'and I also have a separate structural engineering license in the State of Illinois and am licensed in Alberta, Canada. Presently I am a member of the following organizations:

American Concrete Institute American Institute of Steel Construction American Nuclear Society American Society of Civil Engineers

,,y 4 Structural Engineers Association of Illinois j' Western Society of, Engineers

03. What are your responsibilities for the design of the Braidwood Project?

A3. As Project Director for the Braidwood Project, I am responsible for implementation and technical

! integrity of S&L's design efforts. I regularly report to the client regarding S&L's performance on the Braidwood Projec*. and on the status of engineering. I work with Commonwealth Edison (CECO) and the Project Team to establish significant design parameters and direct appropriate application 1-

1 o t of S&L engineering. Prior'to July 1, 1986, I was also the Assistant Manager of the Structural Department. In that position which I held from July 1979, I assisted the manager in coordinating structural, architectural and civil engineering design for S&L. I assisted the manager in all matters of supervision, administration, personnel and technical policies.

Q4. Did you play a role in the development of Sargent

& Lundy Specification L-27907 A4. Yes. In 1975, I was assigned to the Braidwood project as a Structural Project Engineer. In that capacity, I was responsible for the identification and specification of technical requirements for structural welding contained in the various Sargent (

& Lundy specifications used at Braidwood, including I

Specification L-2790. I provided the welding requirements to Mr. Treece,'and thereafter reviewed and provided comments on the document as prepared .

I by Mr. Treece.

05. What standards governing welding requirements are included in Specification L-27907 AS. Three Sargent & Lundy standards were included in 1 Specification L-2790, which relate to welding.

They are as follows: STD-EB-702, entitled " Cable Pan System Field Installation". ,

i

i _4-

'STD-EB-ll5.0, entitled " Seismic Category I Electri-cal Equipment Hangers for Fabrication and Erection".

(

Standard Form 1701 (Rev E), entitled " Standard Specification for Welding in Building Construction".  ;

These standards prescribe welding requirements by 1

invoking industry codes and standards. l 4

l  !

06. What industry welding code is invoked in the S&L  ;

, standards included in Specification L-27907

) A6. The American Welding Society code for structural applications. In addition, the Specification allowed the electrical contractor's procedures to

! be qualified under Section IX of the ASME Boiler and Pressure Vessel code. As Mr. Kurtz explains, the Ernst welding procedures and welding procedure qualifications were based on the AWS Code rather than the ASME code.

07.- What edition of the AWS Code governed the technical l requirements for welding under the contract between

~

Commonwealth Edison and E. C. Ernst?

A7. AWS Dl.1-1975. i k

f- #

08. What is the basis for that conclusion?

A8. As indicated in my previous answer, AWS-Dl.1-75 is not named as such in Specification L-2790. Instead, our specification provides that where the code is invoked in the specification, the latest is' sue of the code as of the date of the contract is to be applied to the work performed under the contract.

In Specification L-2790, this provision is contained in Section 107.7:

All references to American National Standards Institute (ANSI) Standard Specifications, and to other similar standard publications, are to the latest issues of each as of the date of this Contract.

As Mr. Treece explains, the date of contract between E. C. Ernst and CECO was May 3, 1976. As of May 3, 1976, the 1975 edition was the latest publication of AWS Dl.l.

09. Mr. Treece, in Answer 11 of his testimony, identi-fies several changes to the welding requirements imposed on E. C. Ernst. Was there any change to the governing welding code, Dl.1-1975?

A9. No.

Q10. What code governed the welding requirements under f the contract between Commonwealth Edison and L. K.

Comstock?'

A10. Again, the AWS Dl.1-1975 Code.

i

-Q11. What is the basis for that conclusion?

I All. It was not our intention to establish a new set of f

i ' technical requirements.for L.'K. Comstock, including i

! the applicable welding code for the electrical work at Braidwood. As explained by 50:. Treece, the

i. Purchase Order between Commonwealth Edison and-I Comstock incorporated the version of L-2790 that

} had been issued initially to E. C. Ernst which, as I have explained, specifies AWS Dl.1-1-1975 as-j the welding code.
