Local bid-set context
Information to confirm before a Boston estimate
The City of Boston Inspectional Services Department (ISD) administers building, mechanical, and electrical permits, enforcing 780 CMR alongside Boston's Building Emissions Reduction and Disclosure Ordinance (BERDO). Commercial estimating in Boston requires navigating Massachusetts 248 CMR plumbing rules, strict carbon caps, life science wet lab process piping (in the Seaport and Longwood Medical Area), and BWSC utility connections.
- Confirm permit filing through Boston Inspectional Services Department (ISD) and whether the building is subject to BERDO emissions targets.
- Verify compliance with Massachusetts 248 CMR plumbing code, accounting for state-specific drainage fixture unit calculations and venting requirements.
- Measure life science and wet lab process lines with separate line items for acid waste neutralization, RO/DI pure water loops, and lab gas piping.
- Segregate building utility lines from Boston Water and Sewer Commission (BWSC) site connection points, grease traps, and stormwater detention interfaces.
Jurisdiction note: The cited guidance describes City of Boston ISD and BERDO processes. Confirm current project requirements with ISD and the responsible design professionals.

How to prepare a Boston MEP estimate request
Estimating is performed from the project information supplied by the contractor. A clear package helps keep scope, revisions, and assumptions visible through the takeoff; it does not transfer design or code responsibility to the estimator.
Include with the request
- Project address, known permitting jurisdiction, bid deadline, and requested trade scopes.
- Current architectural and MEP drawings, specifications, schedules, bid instructions, and issued addenda.
- Scope boundaries and exclusions, including any site utility or fire-protection items that are outside the requested package.
- Any scope questions or document conflicts you want identified for clarification.
Review and delivery
- Check the received document list and revisions against the bid set.
- Measure the requested quantities from the applicable plans and schedules.
- Flag unclear scope, mismatched schedules, or addenda changes for review.
- Use the estimating methodology and sample deliverables pages to review the stated workflow and illustrative file structure.

Common questions
Boston estimating FAQs
How do you handle Massachusetts 248 CMR plumbing code in Boston takeoffs?
Our takeoffs follow 248 CMR sizing tables, venting configurations, and fixture unit calculations rather than standard IPC or UPC rules.
Does JLG provide BERDO compliance modeling for Boston buildings?
No. JLG provides quantity takeoffs and preconstruction cost models from the supplied drawings. Carbon modeling remains with the project sustainability consultant.
What project information helps prepare a Boston MEP estimate?
Provide current architectural and MEP drawing sets, equipment schedules, specifications, addenda, and any life science process piping schedules.
Have a commercial MEP bid set to review?
Send the project scope, current drawings, specifications, and addenda to discuss estimating support.
