Preservation + Performance

Reconcile historic fabric with contemporary requirements.

Historic facilities rarely offer clean boundaries between architecture, structure, utilities, security, accessibility, life safety, and operations. Interventions must respond to existing conditions while respecting the character and significance of the building.

JS Global supports investigation, architecture, engineering, construction, force protection, forced-entry mitigation, perimeter security, phasing, and modernization. The objective is a coordinated solution that improves protection and performance without treating preservation as an afterthought.

Core Capabilities

Modern performance within an existing legacy.

01

Existing-condition investigation

Field verification, documentation, concealed-condition planning, system assessment, structural evaluation, utilities, access, and operational constraints.

02

Sensitive architecture

Planning, detailing, materials, finishes, repairs, additions, circulation, accessibility, and new work coordinated with significant fabric.

03

Systems modernization

Mechanical, electrical, plumbing, fire protection, controls, communications, utilities, and equipment integrated within constrained conditions.

04

Building hardening

Protective design, structural upgrades, blast mitigation, forced-entry resistance, doors, windows, walls, glazing, and shelter considerations.

05

Perimeter protection

Standoff, access, barriers, bollards, site circulation, monitoring, landscape interfaces, and emergency movement coordinated with context.

06

Phased renovation

Occupied operations, temporary conditions, selective demolition, protection, access, sequencing, discoveries, documentation, and closeout.

Balanced Decisions

Preserve, protect, modernize, and operate.

  1. 01

    Understand

    Historic significance, existing fabric, previous interventions, systems, operations, and constraints.

  2. 02

    Prioritize

    Mission, preservation, safety, accessibility, security, performance, budget, and schedule.

  3. 03

    Integrate

    New systems and protective measures coordinated with architecture, structure, and context.

  4. 04

    Protect

    Existing fabric, occupants, operations, records, materials, and sensitive conditions during construction.

  5. 05

    Document

    Discoveries, approvals, changes, concealed work, testing, closeout, and maintenance information.

Frequently Asked Questions

Historic facility modernization.

01Can security upgrades be added without overwhelming the historic character?
Often, yes. Protective requirements can be studied alongside historic significance, sightlines, materials, structure, circulation, landscape, operations, and authority requirements to identify appropriately integrated solutions.
02How are unknown existing conditions handled?
The team uses available records, surveys, field verification, selective investigation, allowances, decision protocols, documentation, and change controls appropriate to the project’s risk profile.
03Can a historic building remain occupied?
Where conditions permit, work can be phased around secure access, occupant circulation, temporary systems, protection, shutdowns, noise, dust, safety, and continuity requirements.
04Does JS Global coordinate preservation authorities?
Authority and consultation requirements vary. The project scope can include documentation, design coordination, submissions, responses, and construction support involving the applicable owner and preservation stakeholders.
