Narrative:

While on a visual approach to runway 4 at efd we proceeded to the end of the runway. While over the threshold, we noticed an orange 'X' over the runway identifier '4', so we went around. NOTAMS stated 'nonstandard displaced threshold markings.' talked with efd tower and they said several other military/civilian aircraft had also initiated a go around. Spoke with local FSDO and they said they would take care of it. Callback conversation with reporter revealed the following information: the PIC stated that he had been into efd many times over the past yrs. The majority of the flts into efd are military. There was no information related to construction equipment on the intersection of runways 35L and runway 4 in the NOTAM information. The runway had no markings that gave an indication of where the displaced threshold started. He felt that some advanced warning of the 'X' over the runway 4 number and of the equipment would have aided the safety margins of this operation. He has not been back to efd since this incident so it was not known if the FSDO had taken care of the issue.
