Street Navigation and Small Architectural Forms: Choosing the Structural Design

The role of street navigation and small architectural forms in urban projects

Street navigation and small architectural forms (МАФ) are not just the visual image of a city. For municipal services, developers, design institutes, and advertising operators, they are a manageable set of metal structures that must:

• withstand climate and operation for 5–10 years or more;
• be replicable — from dozens to hundreds of locations;
• be installed without stopping traffic and lengthy approvals;
• be serviced without complex equipment and specialized personnel.

Therefore, the key question is not “what will it look like in the render,” but which structural solution to choose for mass deployment — taking into account production, logistics, installation, and budget.

Which types of structures most often go into “series”

For urban projects and B2G customers, several groups of products are usually replicated:

Navigation elements

• steles and pylons with a map of the district or facility;
• direction signs (arrow, flag, cantilever);
• numbered and information plates on poles;
• navigation for parks, embankments, pedestrian areas.

Information and service small architectural forms

• information stands and boards;
• bus stop complexes with navigation and advertising spaces;
• posts with rules for using the facility, opening hours;
• posts for bike parking, parking zones, rental points.

Combined solutions “navigation + advertising”

• poles with a navigation block and lightbox;
• steles with the possibility of placing outdoor advertising modules;
• structures for advertising operators as part of urban projects.

For all these groups, an identical approach to structural design is important: minimize variability, simplify installation and maintenance, and provide a reasonable safety margin.

Basic approaches to structural design for mass deployment

1. Unified frame

Instead of dozens of unique products, it is advisable to provide:

• 2–3 standard sizes of poles and posts;
• a single type of foundation or embedded parts;
• repeating mounting nodes for information panels.

This makes it easier to:

• launch contract manufacturing;
• calculate metal consumption and timelines;
• service and replace individual elements without dismantling the entire structure.

2. Separation of “load-bearing frame / replaceable panels”

A rational approach for navigation and small architectural forms:

• load-bearing frame (post, trusses, embedded parts) — a durable metal structure;
• replaceable panels — the information field that can be updated.

This reduces the life-cycle cost: when branding or information changes, there is no need to replace the entire object.

3. Prefabricated solutions

For mass deployment across a city or region, it is important to:

• provide bolted connections where transport of large assemblies is possible;
• divide the structure into modules that fit transport and elevator dimensions;
• minimize welding work on site.

This speeds up installation, reduces dependence on weather conditions, and lowers safety risks during work.

Choosing materials: steel, stainless steel, aluminum, combined solutions

Material directly affects the cost, service life, and appearance of navigation and small architectural forms.

Carbon steel with powder coating

Most often used for:

• supports, posts, frames of navigation steles;
• frames of bus stop complexes;
• load-bearing elements of information stands.

Advantages:

• good price/strength ratio;
• possibility of complex shapes due to laser cutting and metal bending;
• wide choice of powder coating colors.

Disadvantages:

• demanding surface preparation and coating quality;
• need to monitor coating damage.

Stainless steel

Used where the following are important:

• increased corrosion resistance (near water, embankments);
• premium appearance (central streets, business districts);
• minimal maintenance.

Suitable for:

• decorative navigation elements;
• handrails, railings, parts that are frequently touched;
• individual elements of small architectural forms.

Disadvantages — higher cost of material and processing (laser cutting and welding of stainless steel require careful technology).

Aluminum and composites

Aluminum is often used for:

• panels with navigation information;
• lightbox housings;
• decorative overlays.

Advantages:

• low weight — easier installation and lower loads on the foundation;
• corrosion resistance.

Combined solutions (steel frame + aluminum or composite panels) make it possible to optimize the budget and weight of the structure.

How to choose material for the task

When calculating according to the technical specification, the contractor usually evaluates:

• location of objects (center, periphery, parks, embankments);
• expected service life without major repairs;
• requirements for vandal resistance;
• permissible load on the foundation and existing structures.

Based on this, 1–2 structural options with different materials are proposed, with justification in terms of cost and service life.

Production technologies: laser cutting, bending, welding, painting

For replicable navigation systems and small architectural forms, it is important that the structure is adapted for serial contract manufacturing.

Laser cutting

Used for:

• precise cutting of frame elements and decorative parts;
• perforations, slots for fasteners and installation;
• complex contours of navigation panels.

Properly prepared DXF/DWG files help speed up batch launch and reduce metal waste.

Metal bending

Used for:

• increasing panel rigidity without increasing metal thickness;
• forming boxes, profiles, stiffeners;
• creating neat edges without sharp corners.

Well-thought-out bend geometry often allows replacing thicker metal with thinner while maintaining strength.

Welding

Welded joints are used where the following are required:

• high rigidity and immobility of connections;
• minimal amount of visible fasteners;
• integration of embedded parts, flanges, mounting elements.

It is important to provide access to welds in the design documentation in advance for quality control and subsequent painting.

Powder coating

For urban navigation and small architectural forms, powder coating is the basic finishing option:

• wide choice of colors according to catalogs;
• resistance to ultraviolet and weather effects with proper surface preparation;
• possibility to combine matte and glossy textures.

At the technical specification stage, it is necessary to specify:

• color schemes (main and accent colors);
• coating durability requirements (taking into account installation locations);
• acceptable color tolerances within the series.

What to consider in the technical specification: from placement schemes to installation requirements

A well-prepared technical specification is the basis for an adequate estimate and realistic timelines.

Mandatory sections of the technical specification for calculation

1. Types of structures

   • list of products (steles, signs, stands, bus stops, etc.);
   • approximate dimensions for each type.

2. Placement schemes

   • number of locations for each product type;
   • installation conditions (soil, asphalt, paving, existing foundations).

3. Requirements for materials and finishing

   • preferred materials (steel, stainless steel, aluminum, combined options);
   • color schemes, presence of a brand book;
   • vandal resistance requirements.

4. Installation requirements

   • time restrictions for work (night/day installation);
   • site accessibility (central streets, courtyards, parks);
   • need to dismantle old structures.

5. Project timelines

   • desired timelines for the pilot batch release;
   • planned timelines for the series and volumes by stages.

The more detailed the technical specification, the more accurate the estimate and the lower the risk of revising cost and timelines during the process.

Factors affecting cost and production timelines

Below are the key factors that the contractor considers in the estimate.

At the estimate stage, the contractor usually offers several optimization options — in terms of materials, structural design, and modular division.

Typical mistakes when choosing structural design for series

1. Designing “from the render” rather than from production

A beautiful visualization that ignores technologies (laser cutting, bending, welding, painting) leads to higher costs and delays.

2. Too many unique sizes

Each new size means new tooling, changeovers, and separate logistics. For mass deployment, it is better to limit yourself to several unified solutions.

3. Ignoring installation conditions

Structures that are difficult to deliver and assemble on site increase cost and timelines, especially in dense urban development.

4. Underestimating climatic and operational loads

Heat, dust, temperature fluctuations, contact with de-icing agents — all this affects the choice of material and coating. Mistakes here lead to premature wear.

5. No provision for maintenance

If access to fasteners, power sources, and replaceable panels is not provided, maintenance becomes expensive and labor-intensive.

6. Failure to account for future content changes

Navigation and information fields rarely remain unchanged. The structural design must allow information to be changed without replacing the load-bearing part.

7. Launching series without a pilot batch

Without pilot installation, it is difficult to identify errors in fasteners, heights, legibility, and ease of maintenance. Fixing these in series is more expensive.

How to build the “pilot — refinement — series” cycle

For urban projects and B2G customers, a phased approach is optimal.

Stage 1. Preliminary estimate based on the technical specification

• the initial technical specification and references are provided;
• the contractor proposes structural and material options;
• an approximate estimate of cost and timelines is formed.

Stage 2. Structural design and design documentation

• metal structures are detailed (frames, trusses, columns, supports);
• mounting nodes for panels, lightboxes, volumetric elements are developed;
• solutions for coating and colors are agreed upon.

Stage 3. Pilot batch

• a limited number of products in the main sizes are manufactured;
• installation is carried out in typical conditions (center, residential districts, parks);
• comments on installation, legibility, and maintenance are recorded.

Stage 4. Adjustment and series launch

• changes are made to the design documentation based on the pilot results;
• volumes and delivery schedule are clarified;
• serial made-to-order production and phased installation are launched.

This approach helps avoid scaling errors and keep budget and timelines under control.

Specifics for Tashkent and cities of Uzbekistan

When choosing structural design for street navigation and small architectural forms in Tashkent and other cities of Uzbekistan, it is worth considering:

• Hot climate and solar radiation — it is important to choose powder coating and materials resistant to fading and heating;
• Dust and sand — structures should have a minimum number of horizontal surfaces where dirt accumulates and be easy to clean;
• Wind loads — especially relevant for steles and tall signs; cross-sections of supports and foundations must be calculated;
• Intense urban traffic — structures must be installed quickly, with minimal traffic restrictions;
• Diverse development — from historic centers to new districts, which requires adapting design and structural solutions to different contexts.

Taking these factors into account at the technical specification and estimate stage helps avoid modifications already at the installation stage.

FAQ on estimating and launching a project into production

1. Can the same structural design be used for different districts of the city?

Yes, a basic structural design is usually laid down with the possibility of variations in height, color, and panel content. This simplifies production and logistics.

2. How many product types are optimal for an urban project?

Most often, 3–7 main types (steles, signs, stands, poles) are sufficient, each in 1–3 standard sizes. The rest are variations due to content and color.

3. At what stage is an accurate calculation of foundations and embedded parts needed?

It is advisable to work this out already at the design documentation stage, before launching the pilot batch. For complex nodes, a separate load-bearing capacity calculation is possible.

4. Is it possible to combine navigation and advertising surfaces?

Yes, provided this is incorporated into the structural design: the load-bearing frame must take into account the weight of lightboxes, volumetric letters, and additional wind load.

5. What if the design has already been approved but the structural design has not been developed?

The contractor can adapt the existing design to real technologies (laser cutting, bending, welding, powder coating), offering several simplification options without losing the visual idea.

6. How to plan timelines for mass deployment across the city?

First, the timelines for preparing design documentation and the pilot batch are estimated, then — production capacity for the series and installation capabilities under given conditions (night/day work, site access).

7. Can the project be divided into phases?

Yes, this is common practice: first key areas (center, transport hubs), then expansion to districts. It is important to lay down a unified structural design so that phases do not differ in typology.

8. What does contract manufacturing provide in this context?

The ability to produce replicable metal structures with stable quality and pre-agreed timelines, taking into account all the specifics of a particular urban project.

What to provide to the contractor for estimating and launching the project

To obtain a well-founded estimate and realistic timelines, it makes sense to prepare a package of initial data in advance.

For an estimate based on the technical specification, it is advisable to provide:

• a brief project description (city, type of facilities, planned batch size);
• a list of structure types (steles, signs, stands, small architectural forms, etc.);
• approximate dimensions for each type;
• placement schemes or maps (even in draft form);
• requirements for materials and coating (if already defined);
• design references or a finished design project;
• constraints on timelines and implementation stages;
• installation preferences (time, conditions, presence of old structures).

Based on this data, it is possible to prepare several structural options, an estimate of cost and timelines, and propose a phased plan: pilot — refinement — series.

If you plan to launch a street navigation and small architectural forms project in Tashkent or another city in Uzbekistan, the next step is an estimate based on your technical specification.

Submit a request for an estimate

For a prompt estimate, specify:

• city and project type (district, park, embankment, transport hub, etc.);
• estimated number of locations and structure types;
• whether there is a finished design or structural proposals are needed;
• preferred materials (if defined);
• planned timelines for the pilot and series;
• contact person and preferred communication method.

This will allow the contractor to propose an optimal structural design for mass deployment, taking into account your tasks, budget, and implementation schedule.
