Location Generalized

A secure tenant space rebuilt inside an office building that never closed.

JS Global renovated a 4,565 SF secure tenant space in a fully occupied federal office building, delivered under a competitively bid federal task order. The work rebuilt mechanical, plumbing, electrical, communications, sprinkler, fire alarm, and security systems while the rest of the building kept operating.

Project Overview

Every system in the suite had to be rebuilt around a single secure boundary.

The tenant space sat inside a building full of other occupants, so phasing and coordination mattered as much as the construction.

The scope covered mechanical, plumbing, air handling, electrical, communications infrastructure, sprinklers, fire alarm, security systems, architectural finishes, and doors. JS Global built the space to ICD/ICS 705 specifications and phased the work in close coordination with the building manager.

The Challenge

Bring every utility into a secure space through one controlled point.

01

Route water and waste lines around the secure boundary and isolate them with dielectric fittings.

02

Re-route existing circuits so power enters the space through a single point of entry.

03

Add new ductwork and air distribution without opening the secure perimeter.

04

Modify sprinklers and fire alarm coverage for the new walls while the building stays in service.

The Approach

Phase with the building manager, then rebuild each system to the boundary.

  1. 01

    Phase

    Work was sequenced in close coordination with the building manager so other tenants could keep working.

  2. 02

    Distribute Air

    The team installed new VAV boxes, Z-ducts, security bar grilles, insulation, and access doors, then balanced the system.

  3. 03

    Power

    A new transformer and electrical panel were installed inside the space, with all existing circuits re-routed to a single point of entry.

  4. 04

    Connect

    New pathways and cabling support both secure and non-secure voice and data systems, along with receptacles and specialty lighting for mission-specific needs.

  5. 05

    Protect

    Sprinkler heads were relocated and added for the new layout, and new and relocated fire alarm devices maintained full coverage.

The Result

A rebuilt secure suite inside a working building.

01

A 4,565 SF secure tenant space was built out to ICD/ICS 705 specifications.

02

Mechanical, electrical, plumbing, sprinkler, fire alarm, and communications systems were all rebuilt around the secure boundary.

03

Power, water, and waste services crossed the boundary in controlled, isolated ways.

04

The building stayed fully occupied while the work was completed in phases.

What Made It Work

Every trade was coordinated to the same boundary.

Secure space fails at its penetrations, so every trade planned around them.

Mechanical, plumbing, electrical, and fire protection work all had to cross the secure perimeter in a controlled way. Planning those crossings together, and phasing them with the building manager, kept a small space from disrupting a large building.

Project Questions

Renovating a secure tenant space in an occupied building.

Practical answers about phasing, utilities, and the secure boundary.

01What is a single point of entry?
It means power and other services cross the secure boundary in one controlled location instead of many. On this project, existing circuits were re-routed so electrical service entered the space through one point.
02Why use dielectric fittings on water and waste lines?
Dielectric fittings isolate piping at the secure boundary so metallic lines do not carry a continuous path through it.
03How do you work in a building that stays occupied?
By phasing the work in close coordination with the building manager, so noise, access, and utility shutdowns are planned around the other occupants.
Plan Around the Building

Building a secure space inside an occupied building?

Share the space, the standard it must meet, the building systems involved, and the access rules. JS Global will help plan the phasing and the boundary crossings around the other occupants.
