All of us here are, I presume, proponents of shotcrete in one form or another. I happen to be an advocate of sprayed concrete under all but the most unfavorable circumstances. However, being a supporter of shotcrete is not the issue here...payment for its application is.

Disscussion by Richard A. Kaden
The authors for al lthe papers presented in Session V. PAYMENT PROVISIONS, are to be congratulated on the content of their papers and on their challenge to solve a practical problem that faces both the contractor and owner.

Frank L. Lynch; Discussion by Mr. Richard A. Kaden
Mr. Kaden's proposal to utilize subdivided items under the Variations in Estimated Quantities clause in lieu of the "tunneling by lineal foot" method of payment is not satisfactory from my point of view. The purpose in specifying payment for shotcrete in the lineal foot of tunnel excavated is to assure a sharing of the rish for the work required. Mr. Kaden's method as in the unit price method simply pays the contractor for all work done without having some assurance that overbreak was controlled, rebound was minimized and well qualified nozzleman were used.
