The attached drawings shows the results of those comments. Our discussion included: Making the panels lighter. Because of the need to have no columns between the brick piers the size of an individual gates of 7'-8' x 5' is as small as we can get. Because this is a secure, exterior gate the construction of of the gates must be substantial. We are framing them like the existing panels with the addition of the steel frame for support and rigidity and we are hesitant to make the gates of any less quality materials. Supporting the panels: The idea of lifting panels off of hangers was evaluated and even if we divided the 15' wide panel into multiple panels a weight of 75+/- lbs was not practical because the normal LR maintenance crew is typically one person. This also created probably conflicts with columns between the brick piers. A hinged gate system, with the weight of the gate totally on the brick pier was discussed, but the probability of the weight of the gate pulling the anchors out of the old brick piers eliminated that plan. Also the idea of placing a new column beside the brick pier was discussed and the ability to pour a footing adjacent to the existing pier without effecting the pier and retaining a similar look with the gate panels would be difficult. That is why we decided on a system that carries some of the gate panel load on the hinge (as well as stabilizing the gate panel) and the rest on a roller that support the end of the gate, especially when the gate is fully open. With the system we have the turnbuckle can be adjusted to balance the load between the hinge and the roller. Appearance of the gates. With the multiple panels and the added column both changing substantially the looks of the lattice panels the combination hinge and roller support plan was adopted. This system allows the panels to be very similar to the existing but requires tracks to be poured on the ground to support the gate panels. We are planning on these tracks to be colored like the soil and to be poured flush with the ground. We also propose that the edges of the track be poured in 2 very uneven and even organic manner so that the soil and concrete blend together. We also suggest that bermuda sod be laid in the area so that the grass encroaches on and partially covers the track to that it is even more camouflaged. The edges of the track will not be manicured, in fact it will be treated as a grass area with no other special maintenance. Please review the design shown as it relates to the explanation of the criteria for the panels and let us know if this design does not meet the stated criteria. With your help we hope to be able to release the construction of the panels soon after the mechanical units are installed. Tim Heiple Tim and David, See comments from Brian Discoll of the Arkansas Historic Preservation Program. They have concerns about the excavation needed between the brick piers, as well as the tracks. I stressed the need to secure from theft and for easy access. Since AHPP has the conservation easement, we need to get their approval. Your suggestions?

I have forwarded your reply to our architect, Tim Heiple, and our engineer, David Yarbrough. What I am hearing from them is: 1) the need to secure the area from theft or vandalism, and 2) the need to make it so that only one person is needed to gain access to the air handlers for maintenance. I will let you know their comments.

I think one concern is that, in excavating 16” deep between the brick piers, there’s a good chance of uncovering artifacts. The same is probably true for the roller tracks. The curved, concrete roller track will also be a visual intrusion. Honestly, I can’t help but think that, although the panels are well designed, they are overdesigned. If the lattice panels were made more lightweight, so that they could be removed and moved by one person, the need for the casters and the concrete tracks could be eliminated. We’re talking about two 5’ X 7’ panels. Could they be hung on some type of bar so that they could be lifted off? Do they have to be made secure so that access (theft or vandalism)is restricted? I think we would like to explore the option of making the panels lighter and doing away with the concrete.

What is your opinion on this? Brian From: Minyard, Brian Sent: Thursday, February 08, 2018 1:11 PM To: Mcateer, Stephan; 'Brian Driscoll' Cc: 'Paul Porter' Subject: RE: Access gates to under porch HVAC equipment at MacMuseum Just to clarify, I am fine with the swinging doors. I don’t think they will look that much different than the lattice that is there. What I do have an issue with is the concrete tracks. Brian Minyard From: Mcateer, Stephan Sent: Thursday, February 08, 2018 12:21 PM To: 'Brian Driscoll' Cc: 'Paul Porter'; Minyard, Brian Subject: RE: Access gates to under porch HVAC equipment at MacMuseum I am a visual person, so I thought it might help to provide pics of the area we are discussing. The first pic shows the section where we would like to install the gates to allow access to the air handlers. They would meet in the middle, where the trim piece is, and would be of the same lattice so as to blend in with the existing sections on either side. FYI, the gas meters on the left section will go away with our new HVAC system since it is all electric. Let me know if you have any questions.

I am not fine with the concrete tracks. Is the parks dept. actually going to weed eat around these so they will be functional over time? If we have to have them, can we not do them in brick?
