Friday update from Post Office Square in Lynnfield!

The outside is wrapped up: siding's on, windows are in, and the roof is done. Now the work moves inside, where the fire-rated details around the elevator shaft and mechanical room get finished.

Have a good weekend!

Here's what most people don't realize about building a space you'll own for decades.

Once the drywall goes up, everything inside your walls disappears: the plumbing, the wiring, the blocking and the ductwork. Ten years later, when you renovate or rework a suite for a new tenant, the only map of what's inside is what someone photographed before the walls closed.

A few of the things that matter most to capture:

• Every wall, with a tape measure in the shot: A distance measured from the floor or a door jamb shows you right where a pipe or wire runs, so you don't cut into the wrong spot.
• Blocking: Knowing where there's solid wood behind the drywall makes it simple to hang TVs, shelving, or grab bars later without patching.
• Above drywall ceilings: Ductwork, sprinkler lines, and junction boxes often end up in slightly different spots than the drawings show. A wide photo from a known spot records where they actually run, so adding a light or moving a diffuser doesn't start with guesswork.
• Underground lines before backfill: Measure water, sewer, gas, and electrical from two building corners, and nobody has to dig blind to find them again.

We've built commercial and multifamily projects across New England. The reason owners keep calling us back isn't a secret. We treat the work inside the walls the same way we treat the finish on them.

If you're an owner planning a build, the earlier you bring in an experienced GC, the fewer surprises you hit later.

Lots of progress is happening at Stevens Square! Masons are working the exterior siding while rough-in continues inside. Levels 5 and 4 both passed in-wall inspection, which means the framing, plumbing, electrical, and mechanical behind those walls are signed off and ready to be closed in. Insulation is underway on level 5 and starts on level 4 shortly!

Today is National Tradesmen Day

There are more than 300,000 open construction jobs in America, and here in Maine the median construction worker is 45 years old, one of the oldest workforces in the nation. A gap like that does not close with a job posting. It closes one conversation at a time.

If you know a young person who is good with their hands and restless in a classroom, point them toward an apprenticeship.

To everyone already doing the work, our crews, our subs, and the tradesmen and women on every job around us, thank you.

Cabinets are installed in Building A at the Bath Iron Works housing project!

This is the point on a multi-family job where the rooms stop being units and start being kitchens and living rooms. Same footprint, same walls, but now you can see where somebody is going to stand to make coffee or relax on the couch.

The trades moving through now are the ones residents live with every day. Trim carpenters, painters, and flooring. Quiet work, but the part everybody sees.

More from Bath as the buildings come together.

Floor prep is underway at the Portland International Jetport administration offices!

Existing slabs are almost never flat. So before a single finish goes down, the floor gets ground, patched, and poured with gypcrete until it reads flat across the whole space.

If you are planning a tenant fit-out, this is worth asking about early. Floor prep is one of the first things to get squeezed when a schedule tightens, and it is one of the last things you can fix later.

More from PWM as the space comes together.

This Labor Day, we're thinking about the tradesmen and women who show up early, work in the weather, and leave behind straight lines and square corners that outlast all of us.
Everyone's life benefits from our work together. Thank you.

We're hiring! Our culture is defined by our simple purpose – Build Better Relationships & Better Buildings. We believe taking the time to really know people (each other, our clients, our subcontractors) to be the key behind creating value and leading projects that connect people in New England.

Dr. Julissa Guerra spent years picturing her own practice.

She came to us with a clear vision for the space, down to how she wanted patients to feel walking in. Our job was to turn that into ops, plumbing, imaging, and finishes that all land exactly where they need to be. She stayed involved the whole way, made decisions quickly, and knew what she wanted. That makes a build go well.

Credit to our subcontractors and vendors too. A dental fit-out is a lot of trades working in a small footprint, and this group did it right.

Congratulations, Dr. Guerra! Watching someone open the practice they have been imagining for years is the best part of this work!

Preconstruction is the planning phase that happens after a concept and before construction starts. It's where the drawings, the numbers, and the real-world logistics get reconciled. Done well, it's the cheapest place to solve problems, because changing a line on a drawing costs almost nothing compared to changing a wall that's already built.

A few decisions that matter most in preconstruction:

• Early cost estimating: Pricing the project while it's still on paper means budget surprises show up when they're easy and cheap to fix, not halfway through the build.
• Constructability review: Pressure-testing the design for how it actually gets built catches conflicts between trades before they become field delays.
• Value engineering: Looking for equal-or-better materials and methods at a lower cost, so savings come from smart choices, not cut corners.
• Long-lead procurement: Identifying the items with long delivery windows early, like switchgear, structural steel, or custom glazing, so they never become the thing that stalls the whole schedule.
• Site and permitting due diligence: Understanding soils, utilities, zoning, and the approval timeline up front, so the calendar reflects reality.
• A schedule built from subcontractor input: A timeline informed by the people doing the work is a timeline you can actually hold to.

We've built schools, restaurants, housing, commercial, and industrial buildings across New England, and the pattern holds every time: the projects that run smoothly are the ones that were planned thoroughly before anyone broke ground.

The earlier you bring in an experienced GC, the fewer surprises you hit later.
