HMNS Expansion Update: Finishing Touches From 2011

The push to finish the construction of the Duncan Family Wing is getting underway, and for the most part the visible progress starts to happen on a smaller scale than it has thus far.

One big exception to that statement was last month’s removal of the tower crane from the west side of the building. The task required the use of another giant, but mobile, crane to lift each piece of the tower crane up and over the new building, into the delivery driveway for additional disassembly, and finally onto several flatbed trucks to be carted back to the crane’s winter home in Florida, Arizona, or South Padre.

Hundreds of feet of pipe circulate chilled and hot water throughout the new wing, including these pipes taking water to and from the rooftop air handling units.

Throughout the rest of the building, final finish details are being completed.

Mirrors have been hung in the restrooms. The stairwells are getting coats of warm gray paint. Door handles and light switch covers and illuminated exit signs are being installed. Sensors for lights, sink faucets, and toilet flush valves are functioning, albeit at times a bit over-sensitively. (I involuntarily flushed a toilet from a distance of five feet earlier this week.) All are going in now so the contractor can fine tune the details so they really shine when the building opens to the public.

Much of the detail work this month is happening in the three areas where the new wing will connect with the existing museum at the Wiess Energy Hall, the Herzstein Hall of Special Exhibits, and the McGovern Hall of the Americas. The finishes, meaning wall and ceiling materials and flooring even lighting, are a little bit different at each “tie-in” area because the spaces in both the new and old wing are a little bit different on each floor. The design team and contractor have worked to carefully coordinate the varying field conditions with distinct operational requirements to make each of the tie-in spaces both functional and beautiful.

The site on the west side of the project is being graded in anticipation of landscaping in the coming months.

I can’t wait to share the finished product in the coming weeks.

HMNS Expansion Update: September 2011

If you’ve been searching for a silver lining to the story of our area’s historic drought, here’s a very small one: the museum’s new Dan L Duncan Wing didn’t lose a single day of work this summer due to rain.

Progress on the expansion project has been made at a furious pace over the past few months. Here are some of the highlights:

Walls and roof engaged!

By the end of July the expansion’s gleaming white roof had been torched into place, and the exterior sheathing and glass curtain wall had wrapped its way around the entire perimeter of the building (save for a couple of spots left open for the delivery of interior finish materials.) This condition designates a building as being “dried-in,” an important milestone that releases the contractor to move ahead with finishing climate-sensitive aspects of the project’s interior.

Power Up and Chill Out.

In late June, the permanent electrical service for the new wing was energized, ahead of schedule! Then, just in time for the arrival of the record streak of 100-degree days, the contractor was able to start up the building’s HVAC system. Not only does the flow of air allow the building to breathe a little, protect the interior finishes from melting or molding, and keep the workers from suffering heat exhaustion, but starting up the system this early also allows extensive testing and balancing of the mechanical equipment to ensure air flows well both in the new building and in the existing museum, which will ultimately be served by the new central plant, too.

The HVAC system was switched on in July.
Eventually it will heat and cool both the new wing and the existing museum.

Paleo Hall Transformed.

The vast space of the future paleontology hall, on the expansion’s main level, has been dramatically altered over the summer. Ductwork has been insulated. Sprinkler pipes, lights, and Unistrut have been hung. Drywall soffits and furr-downs have been framed, sheetrocked, taped, and floated, defining the nooks and crannies that will host the fossils and murals and dioramas the HMNS staff has been assembling and designing.

Unistrut are still being installed via scissor lift. Beyond the large white walls seen here are the
boilers, domestic water pumps, and chillers.

The Halls are Alive…

In the expansion’s lower level, bright corridors are now defined as the walls for the new classrooms, animal room, auditorium spaces, and conference spaces are sheetrocked, primed, and ready to be painted. The ceiling grid and support beams for moveable walls to divide the larger classrooms have been installed. Just this week the contractor sawed through the 12-inch thick concrete foundation wall of the existing museum to connect the lower level of the expansion with the Jones Gallery.

Going Up!

While getting the stairs installed was an exciting milestone from our last post, this time the exciting news about getting from floor to floor revolves around the elevators. The platforms, doors, and wall enclosures for the three new passenger elevators are all installed. The contractor is busily constructing the conveying mechanism and cabs for the passenger elevators as well. On the other side of the expansion’s core, the back-of-house service elevator is operational (for contractor use, that is), its shiny stainless steel cab protected by plywood for the next few months.

Every time they catch me taking their picture, they ask for a dollar.
So I had to be really sneaky to capture this valuable image.

The fall season may not bring much needed rain to Houston, but it does promise some exciting developments on the HMNS expansion project, as walls, floors, and ceilings receive their finish treatments and the exterior scaffolding comes down to reveal the building’s snazzy travertine and aluminum coat.
