We report the results of a 1.2 mm continuum emission survey toward
146 IRAS sources thought to harbour high-mass star forming regions. The sources
have FIR colors typical of UCHII regions and were detected in the CS(
) line
survey of Bronfman et al. ([CITE]). Regions of 
,
centered on each IRAS source, were mapped with an angular resolution of ~24´´, using the SIMBA array on the SEST telescope. 1.2 mm emission
was detected toward all IRAS sources. We find that the dust cores associated
with these sources have typical sizes of 0.4 pc and masses
of 
. Dust temperatures and luminosities, derived from the
SED, are typically 32 K and 
.
