Bolt lap ceiling beams without center support Information, help and advice on many architecture, self build and design problems and issues

Hi, can I lap bolt two 4m 12x6cm beams for a ceiling which will have drywall attached to it? The span is 4.8m / 16ft. The trouble is, I cannot carry beams longer that 4m into the site as they will not fit up the stairs and a crane/through is not an option. Thanks!
