Matt Burns of Ed Vance and Associates explains the design development phase of the Two Summerlin Office Building in Las Vegas, Nevada.  He explains how the neighborhood impacted the building design, as well as the structural system and materials used. He also takes us inside the building and explains the interior finish package.

Hi, I am Matt Burns, Vice President at EV&A Architects and today I'm going to talk to you about the Two Summerlin office building here in Las Vegas, Nevada. It is a six-story high rise office building with approximately 150,000 square feet of office space.

The site slopes from, like much of Vegas, from the west to the east, so we've actually taken that into account with the parking structure, so from the building it only looks like two elevated parking levels, with the third one being, subterranean.

Our building is just within the property line here and you can see this other dashed line around the property line which is approximately ten feet back from the property line which is our setback line for our building. Rotating it actually helped us push it a little bit closer to the street on a couple of sides.

So on the site plan we're showing the fire department access with the dash lines that you can see here running through the drive aisles. We're required to have by Clark County Fire access on all four sides of the building and we're actually getting that in this plaza. I can bring the fire truck in up to about 150 feet to get access on the south side.

You'll notice the mechanical room here has the VAV in it, and if I go to the roof plan, so where the rest of the mechanical system is located, there's two cooling towers, some fans, and the heat exchanger is located on the roof. With the bulk of the mechanical system being located on the roof, we had to coordinate with the mechanical engineer to bring all the shafts into the building as well as some of the exhaust shafts for the smoke purge, and those are what you're seeing here along the stairs. Not only do we have to coordinate with the mechanical engineer but also with the structural engineer for all the penetrations in the building.

You can see that there's four water closets in the women's restroom, and two water closets and two urinals in the men's restroom. And the occupant load is based off of the square footage of the floor plate, so we can determine how many occupants will be in a office building and layout the bathrooms based on that number of occupants. So what we're showing here is minimum code requirements and if the tenants want to add restrooms, additional restrooms in their space, they can.

If I go back to the floor plan here, you'll notice that there's steel columns within the space for the gravity loads and we found that it was even economical to put columns at the perimeter of the space to pick up those gravity loads but the panels take care of all the lateral loads, the wind and whatnot. Each of these panels are three stories tall, so there's two panels stacked on top of each other to give you the full six stories. And they are tied into the slab with rebar and HALFEN channels at each floor plate.

This canopy is a little bit, not terribly complicated, but there's a light fixture in it, there's also a gutter in the back so that the canopy slopes back towards the building, instead of off the front so water's not dripping on you as you're walking into the building. There's a couple of exposed channels around this, every one of these areas is blown up even further to show the details in greater depth. For instance, the sheet metal gutter that's at the back and how it drops down into the drain and then how that drain follows down the side of the column and then daylights out the side of the building to make it really clean as possible.

They're tinted windows for all the glass and then we have metal channels that are bolted to the outside of the building, a metal canopy as well as some metal sunshades around the majority of the building. But some of the area was left out, and then the balconies on the south side.

And as we go through this package, every single area is elevated with the materials called out on each sheet and this one is here a kind of a restroom, a look of the restroom with again natural stone on the floor, stone countertops, recessed light cove around the mirror, recessed light fixtures, metal trim, and painted walls where there's no wet fixtures So really carries the finishes from the elevator lobbies right into the bathroom, so it gives it one continuous look throughout the building. Because this is a Class A office building, we really gotta have nice materials that will hold up over the normal wear and tear throughout the day so stone, metals, that sort of thing will kinda stand the test of time.

So, this is a image of what the interior of the elevator, the passenger elevator cabs will look like. We've used some thin metal veneer over the elevator cab with a glass panel on the back, and because of the weight of the elevators we're really restricted to the thickness and the weight of the different materials that we can use. So, we actually are using Gorilla Glass on the back of this wall to create the glass.

And, we've taken quite a few points from each of these with a total of 54 points. So, we're four points above, which is always a good thing. Because, once you go in for review with LEED, you might not get some of the points that you thought you might've.

So the coordination between the different elements that are located in a ceiling like the low lighting fixtures, the mechanical systems, the decorative ceiling, the roll down shutters in front of the elevator doors, etc, etc, was very difficult and very very tight in the ceiling. So it was almost a daily coordination with the contractor as we were building this to make sure that everything fit exactly where we needed it to fit.
