HORSHAM Town Hall redevelopment contractor Kane Constructions is looking to make up for lost time after wet weather and soil contamination caused significant delays to the $19.6-million project.
Horsham Rural City Council technical services director John Martin said the company would update its plans and was considering changing its sequence of works.
"We're just looking to finalise that and then we'll be able to give the public more information," he said.
"The contractors are trying to make up for lost time. Whether they're successful in that we'll have to wait and see."
Soil contamination was discovered at the Pynsent Street end of the site in May.
Three of eight bores tested had low- level contamination, while two contained medium-level contamination.
The contaminant was petroleum-based, suggesting a link to previous fuel stations on or adjacent to the site.
Mr Martin said the contaminated soil had been dealt with.
"Work has been done to delineate the areas where the contaminated soil is," he said.
"The level of contamination is on the positive side of what we'd hoped."
Mr Martin said work was progressing well.
"We had quite a good resumption of work last week and things are full steam ahead," he said.
"Concrete has been poured in the staging area and they've done some demolition of the existing building."
Mr Martin said structural steel and pre-cast concrete had been constructed off-site and was ready to go.
He said significant plumbing work had been done and more bored piers would be drilled this week.
Work on the town hall and art gallery redevelopment started in January and is expected to be completed mid-2015.
