Wold worked with ISD 196 to create an educational facility that would provide a unique set of programs to its diverse population. Th e design focused on respecting and refl ect-ing the rich cultural diversity of district families, as well as emphasizing safety for both staff and students. Flexible, individual and collaborative learning environments are incorporated throughout, since the facility serves as both a district and community resource. Th e ECFE/ECSE/ABE is designed to be fl exible for future program growth and building additions.

Design CriteriaEarly Childhood Family Education, Early Childhood Special Edu-cation, and Adult Basic Education Facility Project

1st Floor Plan2nd Floor Plan

Th e layout of the building is based on Criteria that was given by the district planning group. Th e building is most likely two fl oor. Bus drop off and parent drop off has to be separated. One shared parking. One main public entry. ECSE AND ECFE should be co-located and ABE in a separate area of the building. Commons/ open lab/ computer lab located within ABE spac-es. GYM and other shared spaces to be centrally located/shared. Exterior windows to all large classrooms to maximize natural light. Centralize storage. Windows from classrooms to hallway to allow for natural light.

From the plan you can see that all the classrooms are located at the south end and west end of the building with all the offi ce and shared space in the middle. Th e ABE is located on the south side of the main fl oor with the ECSE and ECFE located on the west side of the building and south and west end of the upper fl oor.

Retaining Wall

Th e building is divided in to two phases. Th e fi rst phase is to building the Retaining Wall in 2013 winter before the ground froze. Th e purpose of this is because the retaining wall is a major components of the building, and with that out of the way the construction of the actual building itself would be a lot fast. Th e retaining wall runs from District Offi ce Dr. Along the east side of the building and along the north wall then to the down to the north-west and in to the ground. It was constructed between November 6th to December 15th.

Project Schedule

Th e overall schedule of the project. Th e project is divided into two phases. Phases one is construction of the retaining wall and phase two is the construction of the building. Th e construction of phase two should take about 10 month starting mid March to mid December. Th e school district plan on opening the facility in January of 2015

STRUCTURE

Th e structural system that is used on the building is a beam and column with slab fl oor system. It is a very traditional system. Th e relatively deep beams provide a stiff fl oor capable of long spans and able to resist lateral loads. Two large I-Beams run along the corridor that is supported by hollow square columns. Secondary I-Beams runs from the main beams to the bear-ing exterior wall with concrete fl oor slabs sitting in between two beams. Th e beams the extends out from the main entry is sprayed with insulation foam at point were the beam go from interior to exterior and they are also fi lled with insulation foam. Th e roof uses ribbed roof decking that sits on I-Beams with secondary open web steel joists in between two beams.

HVAC: MECHANICAL PANTHOUSE

Th e mechanical system of the building is located on the roof in a penthouse. Th e penthouse has 2 pumps for hot water, 3 air handling units, and 2 compressor. Outside air is sucked in from the north side of the penthouse and exhausted from the south through the louvers. Hot water or compressed coolant is pump through pips to each room and based on the temperature of the room air is blow through the pipe and into the room. About 80 percent of the air is cycled and 20% is exhausted out, however, this ratio will change based on the season.

Th e building has pressure sensors that is managed by computer when someone enter or exit the building the computer sense the change in pressure, then it turns on the AHU to equalize the pressure diff erent.

Th e HVAC system in the building is a bit small then other building of this type because the refl ective glazing prevent a lot of solar gain so they are able to make the HVAC system smaller.

ENVELOPE

When we visit the site the envelope of the building is already fi nished and we weren’t given a lot of information on the detail of the wall structure, however, from what we see the wall’s exterior is brick and the interior is made of CMU. Th e sectional diagram shows a typical brick & CMU detail which we assume is very similar to what the building has. All the bricks on the building are layer by mansions on site by hand. A couple large curtain wall can be seen, they are at the stair well, main lobby and on the south side of the offi ce next to the entry. Th e mullen has been installed but most of the glazing is not. Individual win-dows has all been installed and the glazing itself has a refl ective coating that is purposed to prevent heating of the interior from the sun so to put less stress on the HVAC.

Th e envelope for the penthouse is a insulation foam wrapped with a back plastic material. Th e panels edge is design so that each piece clip together with the oth-er and sealer is used to attach the piece together permanently.

Th e extruded box on the facade of the building is going to be covered with zinc panel which will not arrive until November. Th e panels is suppose to arrive early October, however they are delayed.

SITE ANALYSIS CONCLUSION

Th e construction site is at the stage were construction of the exterior is almost done and most of the work is been done inside. Looking at the Schedule and the progress of the construction, the construction has been on schedule most of the time. Th e only delay in the schedule is when parts didn’t arrive on time like the zinc panel. Th e projects budgets is a little be better compare to other building of this type, therefore the equipments and building elements are a bit better than other of this type. For building of this type the construction techniques are all pretty standard nothing innovative, however, while we were there they are in the process of install-ing the main grand stair. Th e stair is broken in to two parts and they were moving the stair from the parking lot in to the building but because the concrete has just been poured and is not dry the lift is not able to drive up. Th ey end up having to put the stair down on to fl at rectangle plates with wheels to get it into the building. I wasn’t’ sure whether that is something they didn’t think about or the concrete didn’t dry fast enough but they way they have to do it seems very ineff ective and its something they have to think about and improve to save time and avoid unnecessary injuries.

We weren’t given a lot of documentation of the building therefore most of what is in the report is from information that Josh told us during the visits and also from speculation from what we seen.

BUILDING ELEMENTS: Stair Fabrications

Bossardt Construction and Wold Architects & Engineers submitted the construction documents of the stairs to the Th urnbeck Steel Fabrication, then Th urnbeck gives Wold the shop drawing for review and approval. Aft er the shop drawing has been approved they start constructing the grand stair. Transportation of the stair to the site is arranged by Th urnbeck. Th e Th urnbeck Steel Fabrication, Inc. is a local fabrication shop that is located in Forest Lake, MN and all stair with in the building is fabricated by them.

Construction Schedule

Shop Drawing

Th e fi rst site visit Josh Grenier, the head designer of the project took us through the building. He showed us where classrooms and mechanical room are located. At the time all the stair is already in the building except the central stair which sits in the parking lot.

Th e fabrication company made the stair with “X-Brace” to keep it from bending and shearing during transportation and installation. (Image on the right) Th e second time we visit the building the central stair was installed.

From the time we visit the site there weren’t enough time for both of us to visit the Th urnbeck Steel Fabrication, Inc. However, Josh Grenier was able to show us the central stair and provide the document and shop drawing.
