CONSTRUCTION & URBAN PLANNING GLOSSARY
Standardized architectural, structural, and regulatory definitions. Clarifies essential abbreviations (POT, CUT, RH, AC), building physics metrics (U-value, thermal bridges), and Romanian construction law frameworks (Legea 50/1991, Legea 10/1995).
POT(Procent de Ocupare a Terenului (Ground Coverage Ratio))
RO: Procentul de Ocupare a Terenului
The percentage ratio between the ground-level built footprint area of a building (Suprafața Construită la Sol - Sc) and the total cadastral plot land area (Suprafața Terenului - St). Formula: POT = (Sc / St) × 100.
Mandatory urban planning constraint established in the General Urban Plan (PUG) or Zonal Urban Plan (PUZ). For instance, a 1,000 sqm plot with a maximum allowable POT of 40% restricts the building ground footprint to no more than 400 sqm.
CUT(Coeficient de Utilizare a Terenului (Floor Area Ratio))
RO: Coeficientul de Utilizare a Terenului
The numerical ratio between the total gross above-ground built floor area (Suprafața Desfășurată Supraterană - Sd) and the total cadastral plot area (Suprafața Terenului - St). Formula: CUT = Sd / St.
Governs total building development density and volume. On a 1,000 sqm plot, a maximum CUT of 2.5 allows a maximum above-ground gross floor area of 2,500 sqm (underground basement areas used for parking/technical rooms are excluded from CUT calculations per Romanian law).
P+1 / P+2 / P+4(Regim de Înălțime (Story Height Classification))
RO: Regimul de Înălțime
Standard Romanian architectural height notation designating above-ground floors: P (Parter / Ground floor) + number of upper stories (e.g., P+1 = Ground + 1 Floor; P+4 = Ground + 4 Floors; S+P+10E+Er = Basement + Ground + 10 Floors + Recessed Penthouse).
Strictly defined in Urban Planning Certificates (Certificat de Urbanism) to regulate neighborhood skyline harmony, solar shadow angles, and seismic design rules under P100-1.
RH(Regim de Înălțime (Height Regime))
RO: Regim de Înălțime
Urbanistic abbreviation designating the maximum permitted vertical envelope height, typically specified both as number of levels (e.g., 2S+P+8E) and absolute cornice/ridge height in meters (e.g., Hmax = 32.00m).
Defines the vertical 3D zoning boundary for developer permits in Urbanism Certificates.
AC(Autorizație de Construire (Building Permit))
RO: Autorizația de Construire
Official legal administrative act issued by municipal authorities (Primărie / Consiliu Județean) authorizing the execution of construction works based on a fully verified Technical Authorization Project (PAC / DTAC).
No civil construction work can legally commence without an active, published Building Permit. Work performed without AC constitutes a legal offense punishable under Legea 50/1991.
