INTRINSIC FEATURES

Description of the building PLOT DIMENSION: 14300sqm TOT. GROSS FLOOR AREA: 7262sqm FOOTPRINT: 3791sqm -26.5% of the plot area MAX. HEIGHT: 8 m GENERAL IINFORMATION: Main goal of creation this middle school was to increase the level of public space and ope facilities in the district through the open spaces in the school's lot. That is why green zone in front of the area as important as the building itself.

As for the building it is a unit of private and public spaces.

We have public and private blocksthat are connected through the inner corridor and outdoors paths. Thiscreate a easily accessible areas. The inner space of the school was designed using CLT panels, using mainly a skeleton structure to allow a lot of flexibility in the educational process for kids.

BUILDING'S FUNCTIONS: PRIVATE BLOCK: Educational -29 classrooms(with 16 people capacity each) Cultural -Library with coworking spaces, common study spaces Recreational -canteen, common spaces Support services -stock area, security center, reception PUBLIC BLOCK: Sport facilities -covered sports ground with tribunes Cultural -auditorium (with 80 people capacity) Support services -technical room, coatroom, stock rooms, changing rooms.

INTRINSIC FEATURES

Pros & Cons CONS

PROS ECOLOGY Energy efficiency (Skeleton structure allows to place glazing as much as needed for daily light, CLT panels have high thermal performance, and does not require additional insulation) Low CO2 footprint Reusable material that can be burned into clean energy SOCIAL Additional public areas for the district Enlargement of the green zone Provides mixed-use facilities for the neighborhood (library and gym open to the neighborhood) Little noise pollution during the construction phase TRANSPORTATION Close location to the M5 metro line Easy accessibility with public transportation

ECOLOGY Usage of non-local material (transportation impact) SOCIAL Close location to the busy roads Destruction of local heritage (demolishing of the original school) TRANSPORTATION Difficult access with private transport DOWNSIDES FOR INVESTMENT The far location from the downtown Increase in construction cost The structure must be dry to prevent it from rotting (cost of ventilation systems)

HEALTH AND SAFETY A healthy environment for breathing Higher fire resistance (in comparison with brick structure and reinforced concrete) Well performance of the structure in case of earthquakes POSITIVES FOR INVESTMENT Flexible can easily be transformed to serve different functions The building has multiple views from inside The shape of the building creates different atmospheres: silent, moderate, and active for different types of users Corridors work both as distribution and leisure spaces

Comparison

The school proposal has been associated with type F1 due to similaritiesin general layout, number of floors,their height and foundation type (fig.1-2).

However, the structure of the proposal is a wooden structure, particularly glulam beams and CLT slabs and wall panels, which is not typical for F1. The new incidence of the structural part was calculated according to the data found for a construction of CLT partitions and wooden structural elements.

Another difference of costs, compared with F1, was calculated according to the bigger number of lift systems,the proposal includes 7 of them, while F1 type 4. The proposal type does not include any masonry partitions.

The excavation and foundation similarities are accounted for due to the nearly same number of floors, their height, general layout and the foundation type.

F1 School from listino - 3 980 m² covered area - 15 classrooms - library - canteen - gym - auditorium - 2 floors

Our school - 7 262,6 m² covered area - 29 classrooms - library - canteen - gym - auditorium - 2 floors

MARKET VALUE

Construction Cost: sources

Conclusion on Market Value

Il Prezzario Regionale - sulla base di quanto previsto dall’art. 23 del D.Lgs. 50/2016 e s.m. e i. (Codice dei Contratti)

Since our project is a public school, the values we accounted for the appraisal of market value are : - Land value : 1 260 755 € - Appreciation cost (we don’t have depreciation for public buildings), this is a construction cost and not a production cost : 5 928 161 € - Profit : for a school, we consider a 3% profit of the sum of the Land Value and the Construction Cost estimations :

Foundations

1 260 755,4 + 5 928 161 = 7 188 916,4 Profit = 215 667,492 €

Our estimate Market Value is 7 404 583 €.

After comparing our building with the reference of the Listino Tipologico, we took into account the shape of the building, its overall dimensions, functions, and after using the UNI_8290 comparison chart, we obtained an overall picture of incidence differences in the new construction.

Conclusion The school proposal on via Sarca in Milan was chosen as a subject of the project work, since it had the elaborated level of design and the sources for market evaluation for Lombardy are accessible.

The first stage of the school evaluation was the in-depth analysis of the extrinsic and intrinsic characteristics. For the extrinsic ones location and the vicinity of the subject property, accessibility and transportation network, quality of the urban environment, attractions and historical evolution were analyses. The school area is calm, clean, surrounded by moderate density residential area, giving green and vast atmosphere. Surrounding buildings mostly in a good condition, newly painted and renovated. There are differentiated functions along the neighborhood, such as schools, university, theatre and musical recording studio or sport center, that creates a circulation in the area and supports the movement of residents.

Second stage of the evaluation was the general description of the layout of the building, technical solutions and details, as well as the quantitative data, such as gross-floor and leasable areas. The project proposal provides qualitative public space, which has a main function of school but can be transformed to the other function such as offices, co-working spaces or other educational facilities. The indoor quality reaches the high level of comfort by the use of CLT panels, aircirculation systems and the vast glazing.

Finally, the cost approach was taken for the evaluation of the market value since public buildings such as schools do not have comparable examples in the open market and do not usually produce an income, therefore cannot be evaluated with sales comparison and income approaches. Market value estimation was started with the analysis of the land value in Biccoca area. The construction cost was calculated, using the data from listino topologico F1 school type, however the cost of the structure was recalculated according to the CLT construction costs (including labour and material cost) in “Il Prezzario Regionale di regione Lombardia”. Similarly, the cost value was estimated using the amount achieved in construction cost calculation and the comparison chart.

As a result of the analysis we consider the final market value 7 404 583 eur as and cost value as 5 928 161 eur.
