30 essential construction terms in Morocco, explained simply
Low wall on the perimeter of a flat roof, serving as a guardrail and waterproofing support. Minimum height is 15 cm above the finished roof level.
Preliminary and Definitive Preliminary Projects. Architectural design phases between sketch and exécution plans. APS defines the broad strokes, APD fixes technical details.
Technical Studies Office. Specialized in structural calculations (reinforced concrete, steel framing), fluids (plumbing, HVAC) or electricity. Required for building permit submission.
Composite material combining concrete (compression résistant) and steel (tension résistant). The most used structural material in Morocco for foundations, columns, beams and slabs.
Horizontal and vertical reinforced concrete éléments that encircle a building's structure. Mandatory under RPS 2000 to ensure structural cohesion against seismic forces.
Ground Occupation Coefficient. Ratio between built surface area and total land area. Set by the development plan, it determines the maximum buildable area.
Land Use Coefficient. Ratio between total floor area and land area. It determines the total authorized density across all floors.
Horizontal reinforced concrete floor (solid or ribbed). In Morocco, hollow core slabs (hourdis + beams) are the most common for residential use.
Business Consultation File. Set of technical documents (plans, specifications, quantities) sent to contractors for quote préparation.
Soil study performed by an approved laboratory (LPEE, Geolabs). It determines soil bearing capacity, water table level and recommends the appropriate foundation type.
Set of steel bars placed in formwork before concrete pouring. The reinforcement plan is prepared by the BET and defines bar diameters, spacing and overlaps.
Structural éléments that transfer building loads to the ground. Common types in Morocco: isolated footings, strip footings, raft foundations and bored piles.
All structure-related work: foundations, load-bearing walls, columns, beams, slabs, stairs. Structural work représents 40-50% of total construction cost.
Hollow concrete or clay éléments placed between beams to form a hollow core floor. Common formats in Morocco: 16+5, 20+5 and 25+5 (hourdis height + compression table).
Moroccan master craftsman. Term for a skilled and expérienced tradesperson in building (masonry, plumbing, electricity, carpentry). The maalem often leads a team of workers.

Urban planning document that defines land use rules in a municipality: buildable zones, purposes (housing, commerce, industry), COS, CUS, heights, setbacks and easements.
Shallow foundation consisting of a reinforced concrete slab covering the entire building area. Used for low bearing capacity soils or high water table levels.
Act by which the owner accepts the work with or without reservations. Provisional acceptance triggers the perfect completion guarantee (1 year) and the ten-year guarantee (10 years).
Darija (Moroccan Arabic) term for building permit. The Rokhas.ma platform has allowed online submission of building permit files to municipalities since 2020.
Moroccan Seismic Construction Regulation (revised 2011). It divides Morocco into 5 seismic zones and imposes specific construction provisions for earthquake resistance.
Thermal Building Regulation of Morocco. In effect since 2015, it imposes minimum thermal performance for new buildings across 6 climate zones.
All work following structural work: waterproofing, joinery (doors, windows), electricity, plumbing, coatings, painting. Finishing work représents 50-60% of total cost.
Shallow reinforced concrete foundation that distributes point loads (isolated footing under column) or linear loads (strip footing under wall) to the soil. Most economical solution for good bearing capacity soils.
Official document issued by the Land Registry certifying property ownership in Morocco. The land title offers the best legal security, unlike Melkia (untitled) properties.
All Risks Construction Insurance. Covers material damage during construction: collapse, fire, flood, material theft. Mandatory for public contracts.
Glazed terracotta tile, typically Moroccan, used for wall and floor covering. Handcrafted in Fez and Meknes, zellige is an iconic élément of Moroccan architecture.
Geographic classification of Moroccan territory by seismic risk (zones 0 to 4 in RPS 2000). Zone 4 (Al Hoceima, Rif) has the highest risk and imposes the most severe construction constraints.
