Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle towers by function, height, structure, ownership and safety, including aviation marking and access.

A tall structure, taller than it is wide, built for observation, transmission, defence, support or display, standing alone or as part of a building.

What it is for: Gaining height, for views, signals, antennas, water pressure, defence or landmarks.

It can be climb or visit it, where permitted; mount equipment on it, such as antennas; inspect and maintain it; mark and light it, for aviation safety.

Distinguishing features

Taller than wide, built for height

Freestanding or part of a building

Masts rely on guy wires; towers are self-supporting

Obstacles to aviation above certain heights

What it looks like

A slender vertical structure, of masonry, steel lattice or concrete, often with a platform or equipment at the top.

Physical character

height: 10-634 m - Tokyo Skytree is 634 m

wind load design speed: 25-50 m/s - depends on site

How it is recognised

Height much greater than width

Antennas, lookout platforms, water tanks or bells at the top

Aviation warning lights and markings

Bundle to layer to finding to question, as the second pass will find it: 4 bundles · 8 layers · 8 findings · 16 questions.

Function What the tower is for.

Function decides design and access.

Use

Observation, transmission, water.

Function

The function.

  1. What is this tower used for? definition
  2. Has its use changed? provenance

Equipment

Antennas, tanks, bells.

Equipment

Equipment mounted.

  1. What equipment is mounted on it, and by whom? provenance
  2. Is there RF exposure near it? boundary
Structure Height and design.

Tall structures are governed by wind and foundations.

Height

Height and form.

Dimensions

Height and structure type.

  1. How tall is it, and is it self-supporting or guyed? measurement
  2. What is it made of? definition

Loads

Wind and ice.

Design loads

Design wind and ice loads.

  1. For what wind and ice loads was it designed? measurement
  2. Has added equipment exceeded them? boundary
Safety Aviation and people.

Towers endanger aircraft and climbers if unmanaged.

Aviation marking

Lights and paint.

Obstacle marking

Marking and lighting.

  1. Is it marked and lit as required for aviation? boundary
  2. Is it in the obstacle database? provenance

Climbing

Fall protection.

Climbing safety

Access and fall protection.

  1. Who may climb it, with what fall protection? boundary
  2. Is public access permitted? boundary
Ownership Who is responsible.

Owners and tenants share responsibility for towers.

Owner

Owner and operator.

Owner

Owner and operator.

  1. Who owns and operates the tower? provenance
  2. Who are the tenants? provenance

Heritage

Historic towers.

Heritage status

Protection status.

  1. Is the tower a protected historic structure? provenance
  2. What changes need consent? boundary

What the second pass must settle

  • Should tower types be separate entries?
  • How should mast and tower be distinguished in data?
  • How should towers be linked to aviation obstacle databases?
