Holding the party in the office saves the venue fee, keeps the date flexible, and means the people who were going to leave at eight can slip back to their desks instead of pretending. It also means the room was designed for spreadsheets, not for sound, and the building has rules that nobody on your team has ever needed to know. We play a fair number of these, in Manhattan towers, Jersey City waterfront buildings and suburban campuses, and the problems are the same everywhere.
Power: the copier is your enemy
An office floor has plenty of outlets, and almost all of them are on circuits that are already doing something. The one by the pantry runs the coffee machine and the microwave. The one on the pillar feeds a bank of monitors. A DJ setup does not draw much, less than most people expect, but it does not like sharing. When a copier warms up or a refrigerator compressor kicks in on the same circuit, the audio hears it as a click or a hum, and a circuit that is already carrying a floor's worth of chargers can trip when the subwoofer hits its first real note.
The fix is a conversation with facilities, not with the event team. Ask which outlets in the party area are on a dedicated circuit, or at least on one that does not serve the pantry or the print room. In a newer building there is usually a floor plan with circuit numbers; in an older one the facilities manager knows from experience. If nobody knows, we bring a long run and find the least-loaded outlet on the day, but it is better to know before load-in than to find out at eight o'clock.
One habit worth adopting: unplug the pantry refrigerator for the night if it shares a circuit with the booth. It will be fine for four hours, and it removes the single most common source of a mystery hum.
Carpet, drop ceilings, and the floor below you
An office is, acoustically, a large soft box. Carpet tiles, fabric partitions, acoustic ceiling tiles, and rows of upholstered chairs soak up the high end. That is good news for speech: a toast in an open-plan office is often clearer than in a ballroom. It is less good for music, which comes out dull, and the temptation is to push the level to get the brightness back. That is the wrong fix. The better one is to bring the speakers closer to the people and keep them at head height, so the high frequencies reach ears before the carpet gets them.
The low end goes the other way. Carpet does nothing to stop bass, and a subwoofer on an office floor couples straight into the slab. The floor below you, and sometimes two floors below, will feel the party as a thump through their ceiling long after they have stopped hearing the melody. If another tenant is working late, or the building has a residential floor, this is where the complaint comes from. We usually run office parties without a subwoofer, or with it on a decoupling pad and turned well down, and put the energy into the mid-range, where it stays on your floor.
Drop ceilings have their own trick: the plenum above them is open across the whole floor, so sound that goes up in the party area comes down in the far corner where someone is on a client call. Keep the speakers aimed down at people, not up at the tiles, and warn anyone who is planning to work through the party that the quiet corner will not be quiet.
Furniture is the last part. Desks on wheels get rolled away and a dance area appears, but the space that opens up is usually a long aisle between two banks of workstations, not a square. That is a fine dance floor if the booth is at one end of it. Put the booth at the end, not the side, so the DJ can see the length of it. We have a post on how much space a DJ needs with the actual numbers.
Building management, security, and the freight elevator
The building is not your office. It has an owner, a management company, and a set of rules for anyone bringing equipment through the lobby, and those rules apply to a DJ the same way they apply to a caterer or a furniture delivery. In Manhattan they are strict and they have a schedule. Elsewhere they are looser but they still exist. The list, in the order you will run into it:
- A certificate of insurance. Most managed buildings want one from every vendor before the vendor is allowed in the freight elevator, naming the building owner and the management company as additional insured, and they want it days ahead. We carry commercial general liability coverage and issue the certificate at no charge with whatever wording the building specifies. Ask the building's tenant services desk for their vendor COI requirements and forward them to us; the details are in our COI post.
- Freight elevator hours. In many office towers the freight runs on a schedule and shuts at a set hour, after which anything coming in goes through the passenger elevators at the building's discretion, or does not come in. A party that starts at six-thirty needs the equipment in the building by five, which means the freight has to be booked for that window. Some buildings charge the tenant for freight use outside standard hours; that is between you and your landlord, but it is worth asking.
- The security desk. Vendor names go on a list. The DJ's name and the vehicle, if there is a dock, need to be on it. Arriving at a Manhattan lobby with cases and no entry on the list is the beginning of a forty-minute delay.
- Union rules. Some buildings require that equipment moved through the building be handled by building staff. It does not change what we do; it changes how long the load-in takes, and it needs to be known in advance.
- HVAC. In many buildings the air conditioning or heat on a floor shuts down at the end of the business day. A hundred people in an office at seven o'clock in December is a warm room and at seven in July is a hot one. Ask management to extend HVAC on the floor for the evening, which is usually possible and sometimes billed.
Alarms, fire doors, and the after-hours building
Offices after hours are protected in ways that do not matter during the day. Two of them can end a party.
The first is the fire alarm. Any fog or haze effect will set off a smoke detector in an office, and a fire alarm in a commercial building brings the fire department and empties every floor. We do not use haze or fog in offices, and if another vendor is proposing it, say no. Related: sparklers, candles in bulk, and anything that smokes on a food station should be cleared with the building, because an office floor's detectors are more sensitive than a restaurant's.
The second is the door. Fire stairwell doors and suite doors that lock after hours cannot be propped open, and some are alarmed. A cable run through a propped fire door is a violation in most buildings and a good way to meet the security supervisor. If the party spans two suites or two floors, tell us, and we will find a path that keeps the doors closed. Our post on covering two rooms with one DJ covers the sound side of that.
Then the small things. Motion-sensor lighting that switches off in the dance area because nobody is at a desk. The alarm panel someone from facilities has to disarm and re-arm. Bathrooms that lock after seven. A cleaning crew that arrives at nine to a party still going. None of these is a crisis; all of them are a five-minute conversation with building management two weeks before, which a venue would normally have had for you.
What to sort out, and what to send us
Before you confirm the office as the venue, get answers from facilities and building management on five things: which outlets are on a dedicated circuit, what the freight elevator hours and booking process are, what the vendor COI wording is, whether HVAC can be extended, and what time the building expects everyone out. Those answers are most of the difference between an office party that feels like a venue party and one that feels like a Tuesday with a speaker.
Then send us the date, the floor and building address, the headcount, and the answers you have. The Corporate Mixer and Corporate Celebration packages cover most office parties, and the pricing page has what each includes. We reply within 24 hours through the contact page.
