About this file

Written by GovTribe AI · Aug 1, 2024

This document contains attachments and drawings for a state and local contract opportunity for the Tech Tower Elevator Modernization project for the Massachusetts Bay Community College in Wellesley, Massachusetts. The project scope includes the modernization of the elevators in the Tech Tower building, including new elevator cabs, control systems, and supporting mechanical, electrical, and fire alarm work. The project drawings and specifications provide detailed requirements for the elevator work, as well as supporting building systems. The project is being bid as a 100% bid set, with a due date to be determined. The contract term is not specified, but it is presumed to be for the duration of the elevator modernization project.

The pricing terms and funding sources are not detailed in this document. There are no indications of any set-asides or incumbent contractors. The overall project appears to be funded by the Commonwealth of Massachusetts and Massachusetts Bay Community College. Additional salient information, such as bonding requirements, prevailing wage compliance, or small business participation, is not included in this set of attachments.
