The article "With ‘Lego Logic,’ Army Engineers Wage Peace One Block at a Time" (ENR 6/9 p. 16) was a super article, but you gave way too much credit to me. The project’s vision was that of the V Corps’ commander, Lt. Gen. William S. Wallace. But the guys who really made it happen were: Lt. Col. Paul Grosskruger, commander of the 94th Engineer Battalion/130th Engineer Brigade; Major Bernie Lindstrom, S3 of the 94th; and Capt. Alex Deraney, commander of the 535th Engineer Company.

Lt. Col. Chuck Eassa, G-39 at V Corps, was responsible for pulling together all the various elements of the Third Infantry Division, who are the troops on the ground making things work every day in Baghdad. Credit should also be given to the fabulous soldiers, non-commissioned officers and officers from the engineers, the MPs, civil affairs, medical/dental, PsyOps, PAO, infantry, etc., who made this great mission a success.

Finally, I would like to acknowledge the great citizens of Iraq who did most of the heavy lifting in cleaning up and repairing their own neighborhoods.

SAPPERS IN! VICTORY CORPS!

Ask the Contractor

After reading your article, "Interstate is Pushed Aside to Accommodate Airport" (ENR 5/26 p. 20), I was vastly disappointed. It was evident that many parties were interviewed for the article with the exception of the contractor performing the work in realigning four miles of Interstate 70.

I am sure your readers would have been interested in knowing some of the following facts associated with this job. Nearly 100,000 tons of lime kiln dust has been used as a drying agent to accommodate earth work during the third-wettest winter in Indianapolis history. Six GPS- equipped dozers are aiding in the placement and slope maintenance of the earth, thus eliminating stakes. The 11,000 ft of 96-in.-dia pipe being installed is a polymer coated pipe that has never been utilized by the Indiana DOT. The polymer coating reduced the weight of the pipe by nearly 50%. The machine installing the pipe, in depths up to 43 ft, is a 250,000-lb excavator.

The aforementioned are just a few of the many interesting aspects of the project that your article "pushed aside." Now that Walsh Construction has been awarded the second phase of the project, I challenge ENR to get it right!
