Airport; Human Factors
After receiving an IFR departure clearance while positioned near the intersection of taxiways A and C; I taxied the aircraft west on taxiway A with the intention of taxiing to runway 8 for departure. After moving only 10 feet or so I noticed there were numerous people and equipment working on either side of taxiway A and about 100 feet east of taxiway E. It was unclear whether there would be sufficient room to safely taxi between the equipment or if they would be capable of moving. There were no NOTAMs published for the airport at the time and no warnings on the AWOS-3 118.07. I elected to back taxi on Runway 8 from intersection C in order to position the aircraft for departure from Runway 8. Upon passing the construction area it was apparent that there would not have been sufficient room for the aircraft to safely clear the workers and equipment. It would also have been impossible to safely turn the aircraft around on the taxiway if I had committed too far west on Taxiway A towards the construction area. Similarly; if any aircraft with a similar wingspan (36 ft) or greater that landed on Runway 26 and proceeded via Taxiway E and A would find themselves trapped on Taxiway A with no way to turn around.The previous afternoon; I encountered a piece of unattended construction equipment on the north side of Taxiway A (same area) that required me to taxi the aircraft along the rightmost side of the taxiway to avoid my left wing from coming too close to the equipment. Immediately after the previous afternoons incident I notified the airport line staff who phoned the Airport Manager; and notified him of the conflict. I believe the construction work and equipment operating so close to active runways and taxiways represent a clear hazard that pilots should be informed of via NOTAM as well as on the automated AWOS recording. I further believe that the lack of response to known conflicts by the airport management represents a general hazard for aircraft operating at IZA.
Reporter clarified the Taxiway designations at IZA (A is parallel; B; C; D; E from east to west) and indicated the current phase of construction is complete but future construction is planned.
Light twin pilot reported construction at IZA that made Taxiway A (the parallel taxiway) unusable. There were no NOTAMs and nothing on the AWOS concerning the construction.
