One person died and five were injured Monday when a West Dallas building under construction collapsed, fire officials said.

Six construction workers had been in the three-story townhome in the 2600 block of Borger Street, near Singleton Boulevard, when it collapsed shortly before 2 p.m., Dallas Fire-Rescue spokesman Jason Evans said.

Five workers were taken to local hospitals with injuries not thought to be life-threatening such as bumps, bruises and fractures.

Nearly four hours after the accident, the body of the dead worker had not been removed from the debris, Evans said. The person’s identity has not been released.

Cadaver dogs performed another search and found no one else in the wreckage.

There were between 20 and 30 people in the area when the collapse occurred, Evans said.

“Considering how devastating that collapse must have been we are very fortunate that the people who did survive survived,” Evans said.

It is not clear if the weather was a factor in the incident, but a storm was moving through the area at the time.

No further information was provided about what may have caused the collapse.

Evans said the investigation will go through the construction company, which he did not identify.

The area is experiencing a construction boom with developers focused on housing, including townhomes and single-family residences.

Megatel Homes is one of the companies that has projects under construction nearby.

Shortly after the collapse, a woman was seen removing Megatel signs from the surrounding area. An employee who answered the phone for Megatel Homes hung up and subsequent calls went unanswered.
