Quarry Visitor Center-Concrete work continued at the shuttle stop on the east side of the building and on the west side of the building near the entrance.

The stone masons made good progress on the stonework on the north and east sides of the building. All stonework should be completed by end of November.

Work began on the photovoltaic system: the stand-offs - the system that anchors the photovoltaic panels - were recently installed and some of the rough electrical work for the system was also completed. Like the new bridge connecting the parking area and visitor center, the photovoltaic system is one of the sustainable features/green technologies that will be factored into the LEED (Leadership in Energy and Environmental Design) certification for the new visitor center.

This week, construction crews formed the  footings and rebar for a couple more grids.

Quarry Exhibit Hall - In the past week, much of the foundation work has been completed and several of the grids have been backfilled. Work continued on two of the remaining grids, with construction crews forming the footings and rebar and, at the end of the week, pouring the concrete.

The park recently selected “Desert Rose”, a dusty-pink paint color, for the Quarry Exhibit Hall (you can see the previous pink used on the building here). Not long after the color was selected, the contractor began priming areas of the exhibit hall for painting. Unfortunately, the selected primer wasn’t compatible with the paint already in those areas: the primer could not adhere to the older, oil-based paint. This week, the contractor tested several new methods and different products and found a solution. Primer application will start next week.

Quarry Visitor CenterThe structural steel and shade structure are complete.

The rough plumbing and electrical work are ongoing.


Over the last few weeks, the stone masons had laid a mock-up wall. This was recently approved and the stonework began in earnest this week and should continue for about another month and a half. The color of the grouting was also recently approved—it’s a great match for the existing grout.

While we're on the subject of the stonework, how's this for a coincedence: the current stone mason learned his trade when he went to Dinosaur National Monument in the late 1970s to help his father work on the visitor contact station that was then under construction.

A lot of progress has been made on the concrete work. The overlook benches, curbs, gutters, new bus drop off, and most of the sidewalks have been completed. This week, work continues on the seat walls, the bridge decking, and plaza this week.

Quarry Exhibit Hall - The grade beam work continues at the quarry. A couple of the grids that were several inches too high and out of alignment have been successfully corrected and are now at the proper elevation. Since these two columns were lowered, the roof drain between the two grids can now function as it should.

Another important grid was recently placed. This is the extra large foundation that is necessary to support the exterior ramp turn-around.

In other work at the quarry, lead paint abatement is ongoing, some of the structural steel has been installed on the north side of the building, and both the primary power replacement and the new waterline bypass tie-in are complete.

Quarry Visitor CenterThe rough electrical work continued in the building.

Rough plumbing work was also underway with the installation of the copper waterline.

The structural steel workers returned to the site this week to work on the shade structure on the south side of the visitor center.

The original building stone has been removed from sections of the east and north walls where windows and doors will be added.

The shuttle bus stop was graded and excavated for a new curb, gutter and sidewalk.

Quarry Visitor CenterElectrical work is ongoing. Storm drain trenching has begun. The in-wall rough plumbing continues with vent and waste piping nearly complete.

Concrete work has been underway: overlook benches have been excavated and formed. The rebar placement is now underway and a concrete pour is scheduled for this week.

A mock-up of the building stone is also underway and the removal of stone on east wall of the former temporary visitor center has begun. The stone must be removed so that a new window and door can be installed.
