Mughal-Era Monument Conservation

Anonymized case study of a multi-year Mughal heritage conservation project with the Department of Archaeology Punjab.

Type: Heritage Conservation | Client: Government Department | Years: Multi-year

Project Overview

A Mughal-era monument under Department of Archaeology Punjab protection required multi-phase conservation. The structure had significant deterioration in glazed tile work, fresco painting, and lime mortar joints. Tender awarded for ICOMOS-aligned conservation following thorough documentation phase.

Scope of Work

Comprehensive documentation (measured drawings + condition survey)
Laboratory analysis of original materials (mortar, pigments, glaze samples)
Glazed tile conservation (cleaning + selective replacement)
Naqashi (decorative painting) consolidation + cleaning
Lime mortar repointing (replacing failed cement repairs)
Structural stabilization of identified failure points
Long-term monitoring plan

Methodology

Documentation Phase

Photogrammetric recording of all exterior + interior surfaces
Tile-by-tile condition mapping (cracked, loose, missing categorized)
Salt content analysis (laboratory partnership with NCA Lahore)
Pigment analysis for Naqashi (mineral identification, binder analysis)
Historical research (archive photos, gazetteers compared against current state)

Conservation Phase

Cement repairs from 1980s/90s carefully removed (root cause of salt damage)
Lime mortar (lime + brick dust + sand) used for all repointing
Gentle cleaning: distilled water poultices, soft brushes only
Missing tiles replicated by traditional Multan kiln workshop (similar glaze composition)
New tiles subtly marked per ICOMOS authenticity rules
Fresco areas: stabilization + careful in-painting in losses (reversible watercolor)
Documentation throughout — every action recorded for future conservators

Challenges

1. Reversing Previous Cement Repairs

1980s/90s cement repairs were structurally bonded to original masonry. Removal required careful manual work — chisels and selective drilling, no demolition tools. Took 3x longer than originally estimated.

2. Sourcing Traditional Materials

Traditional lime mortars require specific lime types (slaked lime, hydraulic lime). Sourcing in Pakistan increasingly difficult. Partnered with specialist kiln in Multan for custom production.

3. Monsoon Disruption

Each monsoon season (3-4 months) work paused — lime work cannot continue in wet conditions. Built schedule accordingly. Total elapsed time longer than active work time.

4. Documentation Standards

Government heritage projects demand exhaustive documentation — far beyond residential. Photo archives, lab reports, decision logs. Required dedicated documentation team.

Lessons

1. ICOMOS principles are not negotiable. Compatible materials, reversibility, distinguishability — these aren't aesthetic preferences, they're irreversibility safeguards.

2. Documentation IS conservation. Without thorough documentation, future conservators have no baseline. Often 30-40% of project effort.

3. Plan for monsoon. Heritage work outside is seasonal. Project schedule must accommodate climate, not fight it.

4. Traditional craft is endangered. Few remaining kilns produce traditional glazed tiles, few mason teams trained in lime mortar work. Investing in capacity building is part of heritage responsibility.
