The Federal Bureau of Investigation, using a fictitious consulting company to infiltrate building contractors and union officials alleged to be corrupt, says it has uncovered evidence of bid-rigging by contractors, payoffs to buy labor peace, and organized-crime influence in the construction industry in the metropolitan New York area. Federal law-enforcement officials said that evidence in the fouryear inquiry was being submitted to a grand jury in Brooklyn. One of the main aspects is possible collusion to rig bids involving millions of dollars by dry-wall contractors -companies that build interior walls in residential and commercial buildings. Among the accusations, the officials said, are charges that some labor leaders tried to force contractors to make illegal payments in return for the leaders' removing pickets and preventing stoppages.

An armed man and woman hijacked a sightseeing helicopter and flew to the Federal detention center in lower Manhattan yesterday morning in an unsuccessful attempt to pluck an inmate from a rooftop recreation area. The apparent target of the scheme, a convicted narcotics dealer, was among a score of inmates who had seized a guard as hostage and were waiting on the roof of the 12-story Metropolitan Correctional Center at 150 Park Row, a modern stone structure set amid the complex of civic buildings near City Hall and Foley Square. But the daring, intricately timed escape plot failed, authorities said, because the hijackers were unable to cut through a heavy wire screen covering the roof. After several unsuccessful attempts to cut through the quarter-inch steel screen with wire cutters, the hijackers had the pilot bounce his two-ton, 35-foot five-passenger helicopter up and down on the mesh, but that also failed to break it. Finally accepting defeat after about 10 minutes on the scene, the hijackers dropped a nine-millimeter pistol through the screen to the inmates. The helicopter then whirled away to a heliport on Manhattan's West Side, where the hijackers sped away in a waiting car.

''America has to be very proud of you.'' - President Reagan to the hostages' families. (A1:3.)

A 5-year-old girl, once independent and cheerful, now refuses to move around the house without her mother or father. She is afraid someone will snatch her away through a window. A group of young boys in a nearby South Side neighborhood used to play in a vacant lot on their street. Now, the boys spend more of their time inside their homes. Across town, a teen-age girl has stopped baby-sitting for neighbors because she no longer wants to be the oldest person in the house. A family that was beginning to allow their 13-year-old daughter out alone now refuses to let her go anywhere unaccompanied. In neighborhoods all around this blossoming metropolis, thousands of families, black and white, have been experiencing an agonizing, unwanted change in their daily lives. A common thread underlies the new living patterns: fear. It rises like a miasma from the 16 unsolved cases of Atlanta's missing and murdered children, in defiance of a generally declining crime rate.
