April 2021 Bid, Rebid & Value Engineering
-
Where we are:
- Bids received March 23rd
- $5.6 Million over the project budget of $92.8 Million
- Filed Sub Bids $1.1M over budget
- Major overruns: HVAC ($1.6M), Electrical ($468k), and Miscellaneous Metals ($300k)
- Non-filed Bids $4.5M over budget
- Major overruns: Steel, concrete, drywall, millwork, curtainwall, and landscaping
Significant value management (VM) across many trades is required to get the project back within budget. The Team has developed a VM list that that will ensure bids do not come in over budget when the project goes back out to bid. Currently, the priced items total approximately $7.1M.

How we got here:
It’s important to understand that this project followed a process that received more cost input than is typical. Below are some of the steps the project took to ensure cost certainty at bid time:
- Estimates were provided early at 50% DD rather than relying solely on the customary 100% DD estimate
- Additional estimates were conducted at the 100% DD, 60% CD, and 90% CD milestones
- The 60% estimate included a 3rd estimator
- A market study was completed at the end of 2020 to better understand where the market was headed in these unprecedented times
- When necessary along the way, the project preformed VM studies to bring the project back within budget
Potential contributing factors for bids coming in higher than anticipated include:
- The major inflation spike that the market is currently going through, which was not obvious even 6-8 weeks ago
- Significant increases in the price of copper, steel, lumber
- Even with multiple estimators reviewing the same drawings, the estimates don’t seem to have captured the more challenging aspects of the design of the project
- VM items decrease customization and create more efficiency for manufacturing parts and during installation
- The bid process included six addenda, which may have complicated the pricing exercise
- This issue will be resolved in the next round of bidding as JLA will be issuing a conformed set of documents that include the information issued by addenda in the first round of bidding
Next steps:
To achieve the above and maintain a September 2023 school opening, the team will follow the timeline below:
- April 16th – Jonathan Levi Architects (JLA) provided a new set of construction documents
- April 22nd – Documents became available to bidders
- May 13th – Bids are due
- Week of May 24th – Gilbane GMP to be approved by Building Commission, School Committee, Select Board
- Mid-June – Gilbane mobilizes and begins construction onsite
