Ok guys, this new job has me living over the drafting table estimating right now. Win a few, lose a lot more. That's how the commercial game is played, BUT, I got kicked in the gut last week. I busted my arse on a large baseball field complex. Sweated over a typical LA's attempt at irrigation design. Finally had most of my peeves settled down in the 159 page addendum issued in the last 48hours prior to bid. This was a 45A site with about 30A of irrigated turf and 8 irrigated infields. The 8 fields were in two groups of 4 with one zone for infield and one turf zone per field. Specs called for THREE 14AWG spares to the end of each main spur, a 12AWG common and a spare 12AWG common. Works out to around 3K of main. Less than 1K is 6" and the rest is 4". Specs require all mains to be on 2" sand bedding with the wires taped every 10' and on the "right" side of the main with flow. 6" main is to have 30" of cover and the 4" main 24" of cover. One of the supply houses did a take off that was close and they bid their take off. I "fixed" their takeoff and had them bid the additions and one other supplier bid the total list. My parts take off came it at just over 75K for the job. I sweated my overall bid of 134K only to find out that the winning bid came in at 108K???? How do you install this kind of system for 30K? This was an RB spec'd system with 3" zone valves (brass with pressure compensation) 12" minimum cover on all laterals, so it has to be trenched (and all but the last heads are all 1.5" and up laterals. It is water way under the bridge, but it still gripes. How 'bout some constructive "how to keep my head straight" while these guys are giving systems away?
