LOE liability periods

Under Spanish LOE, liability runs 10 years for structural defects, 3 years for habitability defects, and 1 year for finish defects, counted from the obra reception date.

Pliego de condiciones

Contractual document in Spanish construction that defines technical prescriptions, measurement rules, and economic conditions; it prevails over drawings in case of ambiguity.

Seguro decenal

Ten-year insurance policy required for residential buildings under LOE art. 9, covering structural damage that compromises the building's safety and stability.

PEM vs PEC

PEM (presupuesto de ejecución material) is the sum of measured quantities times unit prices; PEC adds general expenses and industrial profit, typically 13–19% over PEM.

Measurement deduction rule

In Spanish measurement, openings larger than 2 m² are deducted from wall area; smaller openings are not deducted because their cost is included in the unit price.

Certificación de obra

Progress payment document that certifies executed work based on measurements approved by the site manager; typically retains 5% as a guarantee until final acceptance.

Concrete strength class

Designation such as HA-25 indicates characteristic compressive strength in N/mm² at 28 days for reinforced concrete; minimum cement content in Spain is 250 kg/m³.

Rebar cover by exposure

Minimum concrete cover depends on exposure class: 15 mm for XC1 indoor, 25 mm for XC4 alternating wet/dry, and 40 mm for XS3 marine environments (EHE-08).

Gypsum board types

Placa de yeso laminado types include A (standard), H1 (moisture-resistant), F (fire-resistant), and I (impact-resistant), with common thicknesses of 12.5, 15, and 18 mm.

Thermal insulation lambda values

Typical thermal conductivity: EPS about 0.035 W/m·K, XPS about 0.030 W/m·K, and mineral wool about 0.035–0.040 W/m·K; lower lambda means better insulation.

Deflection limits CTE

CTE DB-SE sets total deflection limits of L/250 for floors and L/300 for cantilevers; active deflection must not exceed L/400 to prevent cracking of partitions.

ULS load combination

For persistent or transient design situations, the ultimate limit state combination is ΣγG·Gk + γQ·Qk + ΣγQ·ψ0·Qk, with γG=1.35 and γQ=1.50.

Column buckling length

Effective buckling length l0 depends on end conditions: fixed-fixed 0.5L, fixed-pinned 0.7L, pinned-pinned 1.0L, and cantilever 2.0L.

Minimum water pressure

CTE DB-HS4 requires at least 100 kPa at the most unfavourable tap and 150 kPa for flush valves to ensure adequate flow in the water supply installation.

Drainage pipe slope

Horizontal drainage pipes require minimum slopes of 1% for DN 100 and 2% for DN 50; ventilation stacks are mandatory for buildings over four floors (CTE DB-HS5).

Evacuation route width

CTE DB-SI requires evacuation routes at least 1.00 m wide; maximum travel distance to an exit is 25 m with a single exit and 50 m with two exits.

Critical path method

CPM identifies the longest sequence of dependent activities in a project schedule; activities on the critical path have zero total float and determine project duration.

Earned value CPI

Cost Performance Index (CPI) equals Earned Value divided by Actual Cost; a CPI below 1.0 indicates that the project is over budget.

Libro de órdenes

Official site log required in Spanish construction where the site manager records daily instructions, incidents, and progress; it serves as legal evidence in disputes.

Edificabilidad

Urban planning parameter (floor area ratio) equal to total buildable floor area divided by plot area; it limits the maximum construction volume on a site.

Licencia de obra

Municipal authorization required before starting construction; minor works may only need a declaración responsable under Ley 12/2012, but major works need a full license.

PGOU land classes

The Plan General de Ordenación Urbanística classifies land as urban (fully developed rights), developable (future development), or non-developable (protected from urbanization).

CTE DB-HE1 U-values

Maximum thermal transmittance for walls in climate zone D is 0.66 W/m²K and for roofs 0.50 W/m²K; stricter values apply in colder zones.

Energy performance certificate

The certificado de eficiencia energética (CEE) rates a building from A (most efficient) to G (least); it is mandatory for selling or renting a dwelling in Spain.

nZEB deadline

Under Directive 2010/31/EU, all new buildings must be nearly zero-energy buildings (nZEB) by 2020; public buildings had to comply by 2018.

Solar thermal requirement

CTE DB-HE4 requires solar thermal contribution for domestic hot water between 30% and 70% of demand, depending on climate zone and backup fuel type.

Aparejador site authority

The technical architect (aparejador) is legally empowered under LOE to direct building execution, sign the final works certificate, and coordinate site safety.

Professional liability insurance

Spanish law (LOE) mandates civil liability insurance for architects and technical architects to cover claims arising from their professional activity in building projects.

Visado colegial

Compulsory professional association stamp on projects submitted to municipalities; it verifies document completeness, professional standing, and compliance with basic requirements.

Conflict of interest duty

A construction professional must disclose any financial relationship with suppliers or contractors and must not specify products in which they have an undisclosed interest.

Obra reception acta

Documentary act signed at completion; if the promoter does not sign within 30 days, the work is deemed received with reservations under LOE article 6.

Safety coordinator requirement

A coordinador de seguridad y salud is mandatory when multiple contractors work on site; the safety plan must be approved before construction begins.
