Crane Prototype Filling NYC

March 2018: Siefert Associates, LLC files its first Prototype with the NYC Department of Buildings. While continuing Crane Notice services, SALLC now files Crane Prototype Applications with the Cranes and Derricks Unit of the NYC Department of Buildings, implementing the allowed use of these new crane and derrick models. SALLC’s initial Prototype application is for a Junttan PM23LC Piling Driving Rig, manufactured in Finland, and never before used in New York City. Once the Prototype application is processed, the rig will have an assigned CD number (Certificate of Operation), and can then start operating within New York City!
