That's far more gov't work than I can stomach each year. The other post, tho, makes a lot of sense- let NAVFAC specify the pipe type!
Its so much easier to get an extra when the evidence you are pointing to, when showing the problem, doesn't have your own logo atop it. Like the C5A hanger that has a draft curtain down the middle of the center system of 3 inat the roof, ensuring at least two of the 3 will dump. Like the engineer that didn't realize churn was higher than rated pressure.... almost 20 years ago they ignored our contractor suggestions and we installed what they specified, then after the acceptance test we removed the 250 GPM foam pumps and installed 300's, plus swapping out the tanks for larger ones....a lot of tax dollars went to Broadview Heights, OH that year. glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ron Greenman Sent: Thursday, July 24, 2008 11:54 AM To: [email protected] Subject: Re: Deperming Pier George, Let Rick get that tax money. You're going to pay it out anyways and at least it'll stay not only in America but in the industry. If he uses cheap stuff the savings might go to a study by Canadian researchers on the effects of Russian vodka on Egyptian dung beetles. I always try to get enough government money each year to pay me back for last year's taxes.
