Commercial Construction: 5 Steps to Remodeling a Business Space

Review the certificate of occupancy

Number one, two, and three on your checklist before even committing to a lease should be: check the CO, check the CO, and check the CO. The document shows what you can legally use a property for—an office, a private residence, a restaurant, etc. Many cities and towns will have online databases where you can download a copy of a property’s CO. Here’s a link to search in New York City.

Understand existing violations on your property

Especially if the property you’re eyeing hasn’t changed hands or had a new tenant for some time, it’s possible it already has building violations. It could be that someone did work without a permit, installed a rooftop AC unit incorrectly, or the fire sprinkler system isn’t functioning. “When you go to get a permit, these things are scrutinized and discovered,” explained Colin, a Sweeten general contractor. If the violations aren’t corrected, that could mean a costly stop-work order on your construction project later on.

Review structural, mechanical, electrical, and plumbing

Now you need to determine if your property can handle the weight of your business. And in some cases, we mean that quite literally. Hernandez’s example illustrates the point: if you want to flip a clothing retail space into a car showroom, it’s a wise idea to make sure the floor can support the added weight. Or how about creating an open-plan office that’s perfect for teamwork? Before drawing up those plans, you need to know what walls are load-bearing and if they can be moved. If moving that wall (or not) is a deal breaker, it’s best to know the capabilities of a space before signing on the dotted line. “You need to ask what are the limits of design,” said Sweeten contractor Colin.

Checking on a building’s envelope

An envelope is building speak for whatever separates the outside from the inside—windows, doors, roof, etc. It’s another area worth looking into before starting your project.

What are your facility requirements?

Most health codes will require an employer to provide access to toilet facilities. For offices, this could mean a shared bathroom on a floor, according to Hernandez, the expediter. “They have to make sure employees have access to a bathroom from within the building,” she said. One client suggested sending employees to another building, but this was not permitted under the health code.

 

Practical Tips for Finding Project Leads

Where are the leads?

Construction leads are always published somewhere. Thanks to the Internet, it’s much easier and cost-effective to find them. For example, a quick Google search for “construction bid leads services” should introduce you to services you might not have been aware of. However, here’s a word of caution: If you’re not familiar with a particular service, ask for a “trial” before you buy. In addition, ask for references of other clients you can call to see if the service is working well for them. Although this may be obvious, make sure the construction bid lead service actually lists jobs that pertain to electrical divisions 16 or 26.

Watch the coverage area

There are a few things you should know before starting your search for construction bid leads in your area. Construction bid boards can promote national, regional, or state jobs. Typically, the more comprehensive the “draw” area of the board, the more expensive the subscription. Therefore, if you mainly work in the state of Connecticut, for instance, you’ll want to subscribe to a service that includes only Connecticut job leads. Why pay for something you won’t use? On the other hand, if you work in multiple states, you’ll want to seek out job lead bid boards that have a more extensive coverage area.

Understand the fee structure

Construction bid lead services charge you a subscription fee, which is typically based on an annual rate. Some companies require payment for the entire year at the beginning of your subscription, while others may charge you a monthly fee. Inquire about a “trial subscription,” if you are unsure about the benefits of a particular lead service.

Popular sites

Perhaps the most recognized online bid board in the industry is Dodge Reports You can search Dodge Reports by geography, building type, and project type. Formats range from a weekly publication, daily bulletins, and newspaper formats. Updated daily, Dodge Reports estimates that at any given time it is tracking almost a half million active projects. Subscription plans begin for as little as $39.99 a month for 25 leads. If you’re going old school, you can also order Dodge Reports in print.

Two-for-one deals

Many of you are probably familiar with the “Blue Book of Building and Construction” In fact, many of you have probably advertised in this publication, the benefits of which are two-fold. First, your listing allows GCs working in your area to find you. Secondly, if you advertise in this book, you will also be provided with job leads in the area in which you advertise via its bid board called BB Bid. Even if you’re not interested in placing advertising in this book, you can at least sign up for a free listing.

 

Constructing your own commercial building

Evaluate your options

The sheer scale of a construction project demands a major commitment from any entrepreneur. Keep in mind that the time and energy invested in constructing a building could also be put into the business itself. Even if you hire a project manager to oversee the job, you’ll still need to be involved in daily decision-making, and that will inevitably mean more time away from daily operations.

Make the right projections

A bank advisor can help you determine the affordability of your project, how much money you’ll need from start to finish and the right financing solutions for your needs. It helps to start with a good business plan so that you can make realistic revenue projections; this will help you gain the confidence of lenders that you can handle a project of this scope without endangering your company’s financial health.

Get your building permit in order

Once you’ve made the decision to build, the next step is to be sure that you’ve satisfied all local rules with the right permit. It’s wise to do this as early as possible, since building without a permit is obviously not an option. Rules can vary greatly depending on whether you’re building new premises, altering existing premises, changing the appearance of a building or altering its use.

Get a good architect or designer

Deterred by the high cost of professional building designers, entrepreneurs will sometimes skip the essential step of hiring a good architect or designer. While you might think you’re saving money up front, you will lose in the end because of problems such as an inefficient use of space. “It’s not just a box that you’re building,” notes Olley. “It has to fit all of your requirements.”

Be realistic about your own involvement

Olley cautions business owners to be realistic in assessing how much time they can devote to the project. Often, companies lose business during construction projects because the management team is less focused on performance and too anxious about the new building. Depending on the scale of the job, Olley recommends hiring project managers who can take care of complex logistics and ensure that the layout designer, architect, engineers and contractors work in harmony.

 

Tips for Remodeling Your Commercial Building

Make sure you take care of permits.

Depending on where the building is located, there could be permits that you’ll need before starting any type of major renovation project. Permits could hinge on whether or not the work is interior or exterior, among other factors. Be sure to double check that you have all permits that you need before you get started to avoid running into complications.

Know who’s managing the project.

With extensive remodeling and repairs, you could have multiple projects going on simultaneously. The project manager will also manage material deliveries and handle any disputes. Make sure you know who the overall project manager is so that you can keep on top of deadlines and milestones and stay abreast of any issues that may come up during the process. This will ensure that the project runs smoothly and stays on course.

Plan Accordingly.

From creating a detailed budget to allowing enough time to successfully complete a renovation project, make sure that you plan for everything. A few things to keep in mind are: managing how your project will affect your tenants, making sure that there are alternatives to whatever space is being worked on (i.e., stairs available if the elevator is under maintenance), and finding the right contractor to handle the job.

The Safety Ways To Switches Installation

Tips for Identifying Light Switches in Your Home

Switch Designs

Switches also come in several designs:

  • Push-Button Switches. Push-button designs are less common than others. This design sports a button that connects or disconnects the circuit when pushed. Some models offer spring-loaded designs that return buttons to their original position after being pushed. Other push-button switches stay depressed when pushed and click back to their original position when the circuit is disconnected.
  • Toggle Switches. Toggle switches are the most common. Toggle designs use a lever that’s angled in an on or off position. Moving the toggle up or down connects or disconnects the circuit.
  • Selector Switches. These switches include a rotary knob or lever that allows users to select different lighting settings. Selector switches also come in a two-mode design. Two-mode selector switches normally only offer an on or off setting.
  • Proximity Switches. Proximity switches use motion-sensing technology to switch lights on or off. Motion-sensing designs are popular in modern and energy-conscious homes and businesses. Proximity switches vary in terms of customization and out-of-the-box features.
  • Photoelectric Switches. Photoelectric switches use a sensor to measure the level of light in a room and adjust the lights accordingly. Streetlights and light posts are common photoelectric applications. But recent innovations have outfitted residential lighting with similar technology. Many homeowners use photoelectric lightings for porches and backyards.
  • Dimmer Light Switches. Dimmer switches allow you to find the ideal amount of light for any setting. The dimmer design is perfect for living rooms, dining rooms, and other areas of your home that call for ambiance. Some dimmers require special bulbs. Be sure to speak to a professional before installing dimmers.

 

Tips for Identifying Wires in your Switch Wall Box

  • An easy way to identify the wires in your wall box is by looking at the color.
  • The Load wire is usually coming from the top of the box. The Line wire is usually coming from the bottom of the box.
  • Before removing the switch, test each wire with a voltage tester.
  • If you’re replacing a current 3-way switch, make sure to mark which wires are connected to the brass screws. Those are the traveler wires and are not needed for the C by GE Smart Switch.

 

Find Hidden Command Line Silent Switches for Setup Files

If you want to Install a piece of software, it’s obviously very easy to do generally speaking. Just run the setup file, agree to the license agreement, select destination location to install, confirm the program’s shortcut location, create desktop and tray icon, and finally install. It looks like many steps are involved but we usually just ignore all those and continue clicking Next until the setup completes. Obviously, these days you have to be a bit more careful because of all the extra options during installation such as installing toolbars etc, but it’s still pretty fast and easy with common sense applied.

Installing an application one time on your computer is not a problem but what if you have just installed Windows and have loads to install? Or worse still, what if you need to install applications on several computers? Sitting there and installing each program manually can be frustrating and a huge waste of time and something you’re not going to enjoy doing. Do we all want an easier solution? Of course we do!

The useful things is, there are hidden command line switches in most installer packages or setup files which be can used to bypass all those confirmation message boxes. With these commands you can install just about anything automatically, if you know the commands to use. Some software developers will include the command line switches in their documentation but many do not and you have to search the internet to find what they are.

 

Ways to Screw up a Switch Installation

In its simplest form, an electrical switch is a humble device. For example, a single-pole, single-throw 15A snap switch consists of a pair of electrical contacts that can be opened or closed manually. A snap switch is spring loaded so that it opens and closes quickly, minimizing arcing, which otherwise would burn the contacts. Of course there are more elaborate types of switches, including:

  • Double-pole, which are capable of simultaneously switching two ungrounded conductors such as in a 240V circuit.
  • Triple-pole, for 3-phase circuits.
  • Electrically or pneumatically powered switches for very large loads.
  • 3- and 4-way switches, which permit users to control a load from more than one location.
  • Circuit breakers, which provide overcurrent protection as well as a switching function.
  • Molded-case switches that resemble circuit breakers. They plug into an entrance panel and pick up power from the bus bars(s) but do not offer overcurrent protection.
  • Isolating switches, which are not intended to interrupt a load.

All non-utility switch installations in residential, commercial, and industrial settings must meet National Electrical Code (NEC) requirements where enacted. In most jurisdictions, the finished installation is inspected prior to use. Since switches are a very visible part of the installation, the electrical inspector almost always sees misapplications and NEC violations because they are out in the open. This gallery features some of the more common violations in switch installations.

 

How to replace a light switch

Never take risks with electrical safety. Before you start any type of electrical work, you must follow these following safety precautions:

Remember to switch off the mains power at the consumer unit/fuse box. Isolate the circuit you plan to work on by removing the circuit fuse. Put this in your pocket to avoid accidental replacement

Or switch off the breaker and lock it if you can

Attach a note to the unit to advise you are working on the circuit.

Check the circuit is dead with a socket tester or voltage tester/meter for lighting circuits. These confirm whether circuits are dead and safe to work on

Check all finished work with a socket tester (or voltage tester for lighting circuits) before using

For your safety, these products must be installed in accordance with local Building Regulations. If in any doubt, or where required by the law, consult a competent person who is registered with an electrical certification scheme. Further information is available online or from your local authority.

Be cautious when opening up multi-way switches. The lights they control should take power from the same circuit, but if yours are incorrectly wired and take power from different circuits, there will be live cables at each switch position when one circuit is isolated. There is more than one method of wiring multi-way lights. If yours does not match the system shown here, that doesn’t necessarily mean they are unsafe.

Use Circuit Breakers To Make A Safe Electric

The importance of circuit breakers in the home

Many homes still use traditional fuses but they can be replaced with an essential safety feature called the circuit breaker. The main function of a circuit breaker is to detect any faulty condition in the electrical system and discontinue the flow of electricity to ensure safety. Many properties have been destroyed and lives lost due to short circuits that could have been aborted in time if there were circuit breakers

A short circuit can be defined as an abnormal low resistance current that is in between two nodes of an electrical circuit that is meant to have different voltages. When there is an excess flow of electric current, it can cause circuit damage that can lead to overheating and in some instances to an electrical fire. The main reason for short circuits is overloading but this can be avoided through circuit breakers that will detect the faulty condition. Generally, circuit breakers are more expensive than fuses but it is an investment that can protect your life and property.

 

Types of Circuit Breaker and Its Importance

There is a broad range of circuit breakers available, which depend upon the voltage, installation, external design, placement, and breaking mechanism.

Here are the different types of circuit breakers:

  • Air Circuit Breaker:

Air Circuit Breakers operates in the air with their arcing contacts exposed. These arcing contacts quench at a given level of atmospheric pressure.  In a lot of countries, the air circuit breakers are generally replaced by oil circuit breakers.
Types of air circuit breakers:

1)Plain Air Circuit Breaker:
Plain Air circuit breakers are also called as Cross-Blast Circuit Breaker. These circuit breakers are fitted with a chamber( arc chute) which surrounds the contacts.

2)Air Blast Circuit Breaker:
These Circuit Breakers are used for a system voltage of 245 KV to 420 KV and more. Air Blast Circuit Breakers are generally of two types: Axial blast breaker and Axial blast with sliding moving contact.

  • Molded Case Circuit Breaker:

The traditional circuit breakers use electromechanical trip unit which may be either interchangeable or fixed. A molded case circuit breaker helps in providing support by bringing together a temperature-sensitive device with a current-sensitive electromagnetic device. Once the mechanism trips, both the circuit breakers start working automatically.

  • Miniature circuit breaker:

Unlike fuses, MCB protects light switches, equipments, circuits, etc. and operates as an automatic switch that opens or breaks the connection when the current flowing through the circuit is excessive. Once the circuit returns to normal, it can be reclosed without any manual replacement. MCBs have the ability to protect against fault arising due to overheating or increase in temperature. The construction of an MCB is such that, it has a bimetallic strip. It is a combination of both magnetic and thermal tripping mechanisms that are implemented in most of MCBs. This is designed to trip within 2.5 milliseconds when an overcurrent fault arises. In case of temperature rise or overheating it may take 2 seconds to 2 minutes for the MCB to trip.

Other than circuit breakers, a distribution management is also important because of the following benefits:

  • Enabling leading critical grid controlling capabilities
  • Optimising the dynamic grid functioning
  • Enhanced outage response

Thus, it is very important that circuit breakers are a component of every home to provide for a greater degree of protection.

 

How to Calculate Amps, Volts and Watts

To start solving the problem, we need to know one simple “rule of thumb” formula. This formula will help us determine if all the electrical stuff on a particular circuit is overloading it. This formula also helps define some everyday terms and how they relate to one another. After all, light bulbs and space heaters are labeled in watts; tools and circuit breakers in amps; and our household electrical system in volts: How do they all fit together?

Voltage can most simply be described as the pressure under which electricity—a chain of electrons—moves. Most household current is pushed at 120 volts, though current to large electrical appliances is pushed at the higher pressure of 240 volts.

Amps (or amperes) is a measurement of the number of electrons the voltage pushes past a given point in
one second.

Watts is a unit of measurement for electrical power. It indicates how many electrons were pushed through an electric gadget to make it work. It’s what the electric company bills you for.

 

WHY ARE CIRCUIT BREAKERS SO IMPORTANT?

Considering the volatile nature of electricity, and the danger that it can pose on your property and health, safeguards are required throughout the circuit that prevent overloading and overheating. These essential electrical safety devices are known as circuit breakers. Basically, if an overload occurs within your home circuit, due to an increased demand for electricity, the circuit breaker or ‘fuse box’ is automatically triggered.

FUSES

Although surpassed by the circuit breaker, fuses are still found in many circuits and offer a line of defence against electrical overloads. When the circuit is operating effectively the fuse is an integral component of the electrical circuit and must be maintained for electricity to effectively flow. However, the fuse is designed to disintegrate when it heats up to a certain level, breaking the circuit and stopping the overflow of electricity before it damages your home. While this is an effective safety method, fuses are only able to be used once and must be replaced whenever they are put to work.

CIRCUIT BREAKERS

Circuit breakers on the other hand are able to be called upon numerous times when the current reaches dangerous levels. Circuit breakers incorporate a electromagnetic switch design which is triggered when the current increases to a volatile level. When an overload occurs, the increased current boosts the magnetic force of the switch and causes it to pull down the metal lever on the switch and cease to the flow of electricity to the house.

 

Circuit Breaker Tips

Knowing how to use a circuit breaker is important. The power may have been cut for a reason, so you want to be aware of potential overloads or electrical malfunctions. It’s important to know which branch circuit each breaker is connected to, so you can identify whether too many devices are connected in, for example, your kitchen or living room.

If you’re using the main breaker to shut off power to the whole house, switch off each individual breaker first, one at a time, and then flip the main circuit breaker off. To restore power, switch the main breaker on. Then reset each individual circuit breaker individually. Resetting them one at a time can avoid a sudden power surge.

Follow a similar procedure if the main circuit breaker trips. Whether this is due to a power surge, overload, or lightning strike, turn off all individual breakers so all circuits don’t turn on as soon as the main breaker is reset. When you do reset the main breaker, stand to the side, turn your head, and preferably wear safety glasses to protect yourself from potential sparks or flashes. Then turn one each circuit one at a time.
