safety is job one

Construction and maintenance sites are dynamic environments where workers engage in activities that may expose them to a variety of safety hazards, such as falling objects, working from rooftops or scaffolding, exposure to heavy construction equipment, or the use of temporary electrical circuits while operating electrical equipment and machinery in damp locations. Through implementation of safe work practices, training, and compliance with federal, state, and local regulatory requirements, Gittleman’s safety program aims to identify, control, or eliminate construction and maintenance related hazards.

Topics we cover on a regular basis include:


When it comes to electrical, plumbing, and HVAC services, there are very specific state and municipal licensing requirements in multi-family dwellings. Therefore, it’s extremely important to be aware of, and follow licensing requirements from a management, employee, and owner perspective. Engaging or permitting unlicensed individuals to perform this work in multi-family dwellings creates a liability exposure for all parties involved.

Building Contractor License

Plumbing License

Electrical License


Any electrical work that includes disconnecting and re-connecting electrical line voltage wiring, installing new components or wiring must be performed by an individual with a state electrical journeyman or masters license and may require a permit. This includes light switches, dimmer switches, outlets, lighting ballasts, hard-wired smoke detectors, etc. This is one of the most important and overlooked trades: residential buildings can have a combination of 110, 208, 277, and 480-volt electrical supplies in both single and three phase operation. Wiring can be solid core copper, stranded copper, or aluminum, often in combination. Mixing wiring or using incorrect connectors, installing switches, outlets, or ballasts that are not compatible can cause explosion, fire, or electric shock. Lighting can be any combination of voltages, magnetic or electronic ballasts, high pressure sodium, High Intensity Discharge, LED, or LED with drivers. Mismatching lighting components or voltages can cause explosion, fire, and/or electric shock.
