Reconstruction and repair of historic buildings

Useful:

• Old photographs;
• Plans;
• Facade;
• Drawings;
• Archival images of the street;
• Documents;
• Photo of previous repairs;
• traces of old elements in the building itself.

If the re-establishment of the lost element is required, the following grounds are needed:

• Photo;
• Similar;
• Traces;
• drawing;
• Research.

Don't give designer fantasies for historical reconstruction.

Before intervention, it is useful to record:

• Geometry;
• thickness of walls;
• gaps;
• Levels;
• Distortions;
• defects;
• Decor;
• Profiles;
• Cotton;
• Wood;
• metal;
• Existing engineering routes.

A complex object may require a separate detailed fixation.

Check for task:

• The foundation;
• Walls;
• Cracks;
• Cotton;
• Curves;
• beams;
• Wood;
• stairways;
• The roof;
• moisture;
• Biotransaction;
• Corrosion;
• Engineering networks.

The reason may be:

• The roof;
• A drain;
• Facade;
• Capillary moisture;
• Ground;
• damaged networks;
• condensate;
• Bad ventilation;
• Wrong new repair.

We need to establish the source first.

Do not close the wet structure with a new trim.

It is important to establish:

• Type of brick;
• Status;
• stitches;
• moisture;
• Salts;
• Cracks;
• Previous repairs.

Too rigid or impermeable repair material may operate differently from the old scrap.

The specific composition is determined by the specialist/project.

The old facade may have:

• Style plaster;
• Cement repairs of different periods;
• Colour;
• A blind decor;
• Crystal;
• Carnivals;
• Cashiers.

Before repair, it is useful to identify:

• What's original;
• That later;
• What's holding up;
• That he is cast off;
• I don't know where the cause of the damage is.

Don't offer to knock everything down to the brick as a standard strategy.

Possible challenges:

• Save;
• Clear;
• Strengthen;
• Renovate;
• Remove the shape;
• to recreate the lost fragment.

However, the execution of the works of art and restoration may require a narrow specialization.

PNVTEAM does not claim to have its own restoration workshop as a standard part of its services.

Subject matter specialists are involved when necessary.

Old buildings may contain:

• beams;
• Curves;
• stairways;
• Doors;
• Windows;
• Strepila;
• The floors.

First assess:

• strength;
• Humidity
• rot;
• Insects
• Connections;
• Previous repairs.

Not to replace the historical wooden element just because it's old.

But not to keep the damaged element just for the sake of age.

Possible strategies:

• Repair of existing ones;
• Recovery;
• Improvement of seals;
• Maintaining the external pattern;
• The production of new historical models;
• modern replacement, maintaining the proportion.

The choice depends on:

• Value;
• Status;
• Energy efficiency;
• Budget;
• Requirements for the object.

Old doors can be an important part of the nature of the building.

Evaluate before replacement:

• The painting;
• Box;
• Furniture;
• Decorative elements;
• Geometry;
• It's possible to repair.

An older house may retain:

• Security fences;
• Gate;
• railing;
• Grids;
• Curtains;
• Decorative elements.

Possible:

• Cleaning;
• Repair;
• Local replacement;
• Strengthening;
• Repeat of lost parts.

Check:

• Strepila;
• Coating;
• Interfaces;
• chimneys;
• A drain;
• Carnivals;
• Ventilation;
• Attic.

The new roofing system shall take into account:

• Geometry;
• Appearance
• Design;
• Vapour mode;
• The historical character.

Old closures may be:

• Wooden;
• metal;
• mixed;
• and later reinforced.

A real evaluation is required before changing the load.

For the old building, it's possible:

• Cracks;
• Sediment;
• moisture;
• Local restructuring;
• The different parts of the foundation.

Strengthening is done only when the need is proven.

We need to determine:

• Which are the load-bearing walls,
• Which are the later partitions?
• Which premises shape the nature of the building;
• Where changes are possible;
• Where's the new toilet;
• Where the kitchen is;
• Where are the engineering mines?

Old houses often need to be replaced in whole or in part:

• Electricians
• Heating
• Water;
• Sewage;
• Ventilation;
• Communications.

Main difficulty:

Conduct modern networks with minimal damage to valuable surfaces and parts.

Do not break the historical fold / decor automatically.

The specific solution depends on the building and can use existing technical zones, attics, basements or local new tracks.

New sanitation and kitchens require a particularly cautious integration.

Check:

• Tracks;
• The slopes;
• Curves;
• Passage;
• Hydroinsulation;
• Ventilation.

Sometimes the location of a new function is determined by the possibility of engineering connection.

An existing building may have:

• Maintaining part of the system;
• Full replacement;
• New radiators;
• Warm floor in selected areas;
• A new boiler room;
• Other equipment.

Do not introduce a modern system without evaluating the protective structures, humidity, ventilation and windows.

With the replacement of windows and the warming, the regime of the building may change significantly.

Once sealed, the old house can obtain:

• Humidity
• condensate;
• mold.

Therefore, energy efficiency and ventilation are considered together.

For a valuable facade, external warming may be architecturally unacceptable.

Possible strategies are determined by the calculation and the object of:

• roof;
• Attic;
• Sex;
• Windows;
• Engineering;
• Domestic solutions;
• Local nodes.

Internal insulation is not a universal solution either: the building’s moisture behaviour must be assessed.

Different strategies are possible for an annex or a new element:

• Exact repetition;
• A neutral continuation;
• A modern supplement.

The choice depends on the building, the task, the environment, the status and the architectural concept.

Documented recovery

There's photos/paintings/identifiers/prints.

Interpretation

There's no exact information.

In the second case, it is more accurate to say:

a new solution in the historical context

rather than:

The restoration of the original species.

The historical colour cannot be reliably determined only by modern photography or memory.

A serious task may require:

• Research on layers;
• Archives;
• A sample collection.

For each element, evaluate:

• Architectural value
• Technical status;
• The possibility of repair;
• Impact on safety;
• The cost of restoration;
• Function;
• compatibility with future use.

Objective:

Keep the valuable, not necessarily the old.

Dismantling may open:

• Old gaps;
• Cotton;
• Painting;
• beams;
• Decor;
• Previous restructurings;
• Damage.

Before the unexpected element is destroyed:

1. Record;
2. Evaluate;
3. Take a decision.

Value is influenced by:

• Survey;
• Careful dismantling;
• Individual details;
• Repairs instead of simple replacements;
• Non-standard materials;
• Hidden defects;
• Specialists;
• Test sites;
• Re-establishment of elements;
• Logistics.

For some of the works, it's reasonable first to test the solution on a small fragment:

• Cleaning;
• Plaster;
• Colouring;
• Battery repair;
• Rehabilitation of the tree.

This makes it possible to assess performance, compatibility, technology and labour-intensive.
