Technologies of High-Rise Construction — Real Estate Development

Structural Systems

The choice of the structural system is one of the first decisions in building design. It determines the cost, timeframes, architectural possibilities, and the durability of the building.

Monolithic Reinforced Concrete Frame

Description: the load-bearing structure is made of cast-in-place reinforced concrete—the columns, walls, and floors are poured on site in formwork.

Advantages:

High strength and durability (100+ years)
Open floor plans (no need for load-bearing walls)
Possibility to implement complex architectural forms
Height up to 100+ floors

Disadvantages:

Long duration (dependence on weather, concrete strength gain)
High labor intensity
Requirement for skilled workers

Cost: EUR 400–600/sq. m (structure), AED 1,500–2,200/sq. m in the UAE

Application: business and premium class housing, high-rise buildings, unique projects.

Monolithic-Brick Construction

Description: monolithic frame + brick infill for exterior walls.

Advantages:

Combines the strength of monolithic concrete with the thermal insulation of brick
Good indoor microclimate
Attractive façade (natural brick)

Cost: EUR 450–650/sq. m, AED 1,600–2,400/sq. m in the UAE

Panel Housing Construction

Description: the building is assembled from factory-made reinforced concrete panels (walls, floors).

Advantages:

High speed of construction (one floor in 3–5 days)
Low cost
Factory quality (consistent parameters)
Minimal dependence on weather

Disadvantages:

Limited architectural possibilities
Standardized floor plans (load-bearing walls)
Issues with sound insulation at panel joints
Transport limitations (panel size)

Cost: EUR 250–400/sq. m, AED 1,000–1,500/sq. m in the UAE

Application: large-scale residential construction, economy and comfort class.

Modern Panel-Frame Construction

Modern house-building plants (DSK) manufacture next-generation panels:

Improved thermal insulation (three-layer panels)
Variety of façade solutions (ventilated façades)
More flexible layouts (wider span between load-bearing walls)
Improved sound insulation at joints

Examples: Bouygues Construction (France), CIMOLAI (Italy), Emirates Precast (UAE).

Frame-Monolithic Construction

Description: monolithic frame (columns + floor slabs) + non-load-bearing walls made of lightweight materials (aerated concrete, brick).

This is the most common technology for residential buildings of comfort and business class, as it provides:

Open floor plans (walls can be moved)
Acceptable cost
Good architectural possibilities

Stages of High-Rise Building Construction

1. Preparatory Period (1–2 months):

Setting up the construction site (fencing, site huts, warehouses)
Laying temporary utilities (electricity, water)
Installing a construction crane
Geodetic marking of axes

2. Substructure — Foundation (2–4 months):

Earthworks (excavation of the pit)
Installation of pile foundation (if necessary)
Installation of the foundation slab
Waterproofing

3. Erection of Frame (8–18 months):

Installation of typical floor: 7–14 days (monolithic) or 3–5 days (panel)
For a 25-story building: 6–12 months

4. Façade Works (3–6 months):

Insulation (mineral wool or PIR boards)
Installation of façade system (ventilated façade, plaster, brick)
Installation of windows

5. Engineering Systems (6–12 months, parallel with the frame):

Vertical risers (water supply, sewage, heating)
Electrical installation
Ventilation
Elevators

6. Interior Finishing (3–6 months):

Floor screed
Wall plastering
Finishing of common areas
Apartment finishes (if applicable)

7. Landscaping (3–6 months):

Asphalt paving of roads and sidewalks
Landscaping
Children's and sports playgrounds
Lighting

Marketing of Development Projects: From Offline to Digital Channels

Marketing of residential real estate has undergone radical changes over the past decade. Whereas in 2010 the main channels for attracting buyers were newspaper advertisements, property exhibitions (CITYSCAPE, MIPIM), and a network of agents, today 70–80% of initial interest is generated through digital channels. Key digital marketing tools for developers: targeted advertising in Meta (Facebook/Instagram) and Google Ads allow reaching potential buyers by demographics, interests, behavior, and geolocation with accuracy down to the neighborhood; email marketing to a database of registered leads (lead nurturing); SEO-optimized project websites with virtual tours (VR/360°) and online finish configurators; PropertyFinder, Bayut, Rightmove, Zoopla—aggregators that are indispensable for market presence; YouTube channels with video streams from the construction site increase trust and retain the attention of potential buyers. The marketing budget for a major development project in Dubai amounts to 1–3% of GDV—for a project worth AED 500 million this is AED 5–15 million. In the UK, a comparable figure is 1–2% of GDV. Agent commissions (3–5% in the UAE, 1–2% in the UK) are a separate line item.

Practical Assignment

<details> <summary>Assignment: Choosing a Structural System</summary>

For each project, choose the optimal structural system and justify your choice:

Economy-class residential complex, 1,000 apartments, 10 buildings of 17 floors each
Business-class club house, 50 apartments, 12 floors
Residential skyscraper, 60 floors, 300 apartments

Sample Answer:

Panel construction — maximum speed and minimum cost for mass construction
Monolithic-brick construction — open layouts for business-class buyers, brick façade as a quality marker
Monolithic frame — the only technology that allows construction at this height

Construction Quality Control

Construction quality is a critical aspect, affecting the developer’s reputation and potential warranty costs:

Incoming Inspection:

Verification of quality certificates for all incoming materials (rebar, cement, concrete, brick)
Laboratory testing of concrete cubes (every 50 m³ of concrete poured)
Control of rebar characteristics (manufacturer’s certificates)

Operational Control:

Designer's supervision: site visits during performance of concealed works
Customer’s technical supervision (engineer-inspector): constant on-site control
Construction supervision log with recording of comments and deadlines for their elimination
Geodetic control (compliance of axes, floor levels): tolerance ±5–10 mm

Acceptance of Works:

Acceptance of concealed works before closing (rebar before concrete pouring)
Intermediate acceptance at stages (substructure, shell, roofing, engineering)
Final acceptance by state commission (DEWA approval in the UAE, Planning Inspectorate in the UK)

Systematic quality control at all stages of construction reduces the developer’s warranty costs by 20–35% and decreases the risk of reputational losses upon handover of keys to buyers—especially critical in highly competitive markets of the UAE and the United Kingdom, where buyer reviews are widely distributed through social networks and rating platforms.
