What makes it interesting?
All work was completed while a temporary bypass was in place and the pipelines in the station were active and under full working pressure. The major obstacle of the project was dealing with tight access points due to being in a residential neighborhood.
How HCSS Software assisted with this project
HeavyBid was a very powerful tool that allow BOND to be successful in being awarded the project. Bidding to a private client, BOND was required to provide very detailed unit costs and work zone breakdowns, as well as prepare several iterations of the proposal as the requirements changed during the negotiation process. HeavyBid allowed us to generate a cost analysis to compare different alternatives for the project, specifically the delivery and installation of the meter building.
This project, started in April and completed in August 2014, involved the demolition and reconstruction of the Spectra Energy Needham Regulator Station. The team demolished the existing regulator, installed new regulators, inspected and recoated the existing pipeline headers, and installed a new pre-cast concrete building over the equipment. The existing pipeline bypass on site was removed and disposed of.
Major construction activities included demolition and disposal of the existing CMU Block Building; installation of H Piles and lagging for support of excavation to protect adjacent pipe lines; installation of dewatering pumps and discharge area; excavation using a Vacuum Excavator for new foundation; loading and transporting soil for disposal; construction of new concrete building foundation; removal of existing 4-inch and 8-inch regulator piping; backfill of building floor and foundation using a tele-belt truck conveyor; fabrication, hydrostatic testing, and installation of new 10-inch regulator runs and a new 6-inch regulator run; transporting to the site and setting the new segmental precast concrete regulator building; installing new electrical/instrumentation and control piping; removal and disposal of bypass piping; and restoration of site and demobilization.
