Rotary Car Parking System

It is simple to operate with the driver parking and leaving the vehicle in the system at the ground level. Once the driver leaves the incorporated safety zone the vehicle is automatically parked by the system rotating to lift the parked car away from the bottom central position. This leaves an empty parking space available at the ground level for the next car to be parked on.

Rotary Car Parking System 1

The parked car is easily retrieved by pushing the button for the relevant position number the car is parked on. This causes the required car to rotate down to ground level ready for the driver to enter the safety zone and reverse the car out of the system. Except vertical car parking system all other systems use a large ground area, vertical car parking system is developed to utilize maximum vertical area in the available minimum ground area.

It is quite successful when installed in busy areas which are well established and are suffering with shortage of area for parking. Although the construction of this system seems to be easy, it will be par from understanding without the knowledge of materials, chains, sprockets, bearings, and machining operations, kinematic and dynamic mechanisms.CharacteristicsFirst the mechanical parts have to be designed and created.

I am providing with the design made in CAD and pictures of each part.Pallet is a platform like structure on which the car will stay or lift. It is designed in such way that all car is suitable for this pallet.

It is made from mild steel plate and shaped in fabrication process.A sprocket or sprocket-wheel is a profiled wheel with teeth, cogs, or even sprockets that mesh with a chain, track or other perforated or indented material. The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain passing over it.

Rotary Car Parking System 2

It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.Sprockets are of various designs, a maximum of efficiency being claimed for each by its originator. Sprockets typically do not have a flange.

Some sprockets used with timing belts have flanges to keep the timing belt centered. Sprockets and chains are also used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can be run at high speed and some forms of chain are so constructed as to be noiseless even at high speed.

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic,industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket.

It is a simple, reliable, and efficientmeans of power transmission.A bushing, also known as a bush, is an independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications; this is the most common form of a plain bearing. Common designs include solid (sleeve and flanged), split, and clenched bushings.

A sleeve, split, or clenched bushing is only a "sleeve" of material with an inner diameter (ID), outer diameter (OD), and length. The difference between the three types is that a solid sleeved bushing is solid all the way around, a split bushing has a cut along its length, and a clenched bearing is similar to a split bushing but with a clench (or clinch) across the cut. A flanged bushing is a sleeve bushing with a flange at one end extending radially outward from the OD.

The flange is used to positively locate the bushing when it is installed or to provide a thrust bearing surface.Connects the pallet to rod using square bar.Holds together, the L shaped connector, bar.

Thus holding the pallet.Used in pallet assembly, connecting pallet to frame.Delivers power.

It is the structural body which holds the total rotary system. Every component like the assembly of pallet, motor drive chain, sprocket, is installed over it.Pallet base with beams are assembled to create individual pallets.

Finally all pallets are connected to frame and motor connector are assembled. Now it is time for electronic circuit and programming.We use ARDIUNO for our program.

The electronics parts which we use are given in next steps. System features are:The circuit uses an Atmel ATmega328 (ATmega168 also can be used, or any standard arduino board). It interfaces with LCD, keypad and Motor driver using standard library.

The driver requirements are based on the actual physical scaling of the rotary system. Torque required is to be calculated beforehand, and motor has to be selected accordingly. Multiple motors can be driven with same driver input.

Use separate driver for every motor. This may be needed for more torque.The circuit diagram and proteus project is given.

It is possible to configure speed, individual shift angle for each step, set steps per revolution value etc, for different motor and environment flexibility.Features are:To program the chip (or arduino), arduino ide or arduino builder (or avrdude) is required.Steps to program:There is a good post at arduinodev about upload hex to arduino here.

Source code of project - Github source, you want to use Arduino IDE to compile and upload.Total costing was around INR9000 (USD140 as per dt-21/06/17).The component costing varies with time and place.

What should an efficient parking system look like?
What should an efficient parking system look like?
by:Shenzhen TGW Technology Co.,Ltd       When talk about parking lot systems, we are all familiar with it. A high-quality parking lot system must not only pay attention to high efficiency but also have some advantages that others do not have to be considered a high-quality parking lot system. So how to judge whether the parking system is of high quality? Then we must explore the following aspects.        Reliability and stability: The stability of the equipment is very important to the equipment itself. The reliability and stability of the product are related to the length of its service life. The equipment must have self-protection and strong self-repair capabilities to ensure the system. The smooth running life is as long as possible.        Cost-effective: The selection of the parking system is very important. How to choose a more cost-effective device? The configuration of each device needs to be determined according to the requirements of its parking lot environment. Under the premise of meeting the requirements of the parking lot, the system's complete set of prices is guaranteed to below, and then the system has a high-cost performance.        Compatibility and standardization: Compatibility is the key to combining devices from different manufacturers. The system should effectively communicate and share data, as far as possible to achieve compatibility and interoperability between different devices. The higher the standardization of the system and the better the openness, the longer the service life of the system.        A high-quality parking system needs to be selected and judged from various aspects, but it is more important to meet the use requirements of the parking lot, which can provide people with a good parking experience from various aspects such as parking, payment, and parking.

Benefits of Getting the Automated Commercial Car Parking Systems
Benefits of Getting the Automated Commercial Car Parking Systems
The obvious benefit of automated parking systems is the ability to fit more cars in less space which can solve many parking problems, but there are many other benefits to the developer, operator, consumer and society in general. For example, consider the countless acres of open space consumed by parking lots. Self park ramp garages are more efficient, but still take twice the space as an automated commercial parking facility. By contrast, automated residential or commercial garages are a green solution since they preserve open space, have low energy consumption and have no carbon emissions, because vehicles are shut off before being parked in the system. The mechanical system works according to the same principle as a high-bay storage system and is very easy for customers to use. The entire operation seen in typical automated car parking systems can be shown in the following simple steps: 1. The customer parks his vehicle in a large hand-over room, just as he would in a garage at home. But the advantage with this parking system is that a parking aid will provide precise information on whether the car is in the correct position. Afterward the vehicle is measured and weighed. 2. The customer leaves the vehicle, answers three short questions at a terminal in a side room and receives a ticket. What happens next occurs automatically. 3. After sensors have checked to make sure no people or animals remain in the vehicle, the car and the palette it is parked on are moved into the transport unit and realigned. 4. Using a palette system prevents any harm coming to the vehicle as it is not touched at any time during the parking process. After realigning the vehicle it is transported to an empty parking space within the shelf system. 5. When the customer returns, he is required to pay the parking fee at the payment machine. Once paid, the transport unit retrieves the car from its shelf and returns it to the hand-over room. 6. Then the customer enters the hand-over room and drives the car out without having to drive backwards as the vehicle is already positioned in the right direction. Automated Car Parking Systems - How It Works Once the customer has dropped off his vehicle in the hand-over room a crane mechanism turns the car in the right direction and transports it into the shelf system, where the vehicle is safely deposited in an empty parking unit. The unique feature of this mechanical system is that even the space between the hand-over room and the destination can be used for storing cars as it consists of a rack of movable parking units. This patented combination of fixed and movable racks enables the automated car parking system to achieve the maximum amount of parking space for any given building, ensuring high capacity parking on minimum floor space. When the customer comes to pick up his car he is informed in which hand-over room the vehicle will appear. The system then retrieves the car and returns it to the hand-over room with the front of the vehicle facing the exit, allowing the customer to drive straight out of the automated system.
Car Parking Made Easy
Car Parking Made Easy
More than the traffic police, shoppers visiting congested areas around Meenakshi Sundareswarar Temple in their four-wheelers can heave a sigh of relief now.For the first time in the southern districts of Tamil Nadu, a textile showroom has provided an automated multi-level car parking facility for its customers near its outlet on East Avani Moola Street. About 40 cars of all sizes can be parked at this facility with ease.Owing to inadequate space, it is common to see four-wheelers and other vehicles parked on the roadside, causing congestion to road users. It is a daily chore for the traffic police to pursue violators and impose fines or tow the vehicles. Ultimately, vehicles parked on the roadside resulted in shrinking of carriage space and broad roads appearing narrow.With vehicle population growing at a rapid pace even in tier two cities such as Madurai, finding a permanent solution to the issue of parking of vehicles seemed to be a difficult proposition. In some cities, the officials (town planning and traffic police) admitted that the situation had gone out of control. We have learnt to live with traffic congestions and moving at a snail's pace on main thoroughfares has become the norm, officials say.Customers coming from near and afar expressed difficulties in visiting our showroom owing to lack of parking space for their cars. Now they can heave a sigh of relief, said R. Muruganand, Managing Director of Rajmahal, a leading textile showroom in the city. With the available space near the showroom, RR Parkon Private Limited, a leading infrastructure provider of automated multi-level car parking systems, have built the facility for the exclusive use of Rajmahal's customers.Speaking to reporters here on Friday, RR Parkon Director Balachandran Dharmen said that depending on the space available, the provided the right model for its clients. Giving an example, he said, in a residential apartment, where only three cars could be parked normally, they could provide space for 50 cars. Vehicles are not only safe and parked in an organised manner, but complaints of thefts can be avoided and mischief mongers can be kept at bay, he said.There were various types of models. And in any given type, the vehicle could be taken out in less than 100 seconds. The operation was simple. The main advantage of mechanised car parking system was that in a small area, a large number of cars could be parked, he said.The company was associated with some of the best names in realty business by providing innovative parking solutions at an optimum cost. The company had completed over 100 projects in many cities across the country. They were keen on taking up projects from government-owned lands on a build-operate-transfer (BOT) basis, Mr. Dharmen said.By constructing many multi-level parking facilities, congested locations in the Temple City may soon turn to be most preferred destinations for shoppers.
Automated Car Parking Management System with Several Features
Automated Car Parking Management System with Several Features
Automated car parking management system is basically an architecture, designed in such a way so as to manage many car-park areas in which each car-park area is equipped with an automatic till. This system is enabled with an entry gate and an exit gate with closed circuit television cameras for capturing the image of the number plate of a vehicle on its way in and out respectively. Automated Car Parking Management communicates by the medium of internet with a remote control center. Automated Management System offers state-of-the-art parking management system that lives up to the requirements of professional and innovative management of modern car parking. In this automated system, we can provide car-parking systems for both ground level parking and multi-storey car parking with several features. These features include: - Access to the area - Control of vehicle flows - Manual and automatic mode of payments - Can supply account and administrative statements to the authorised person - Access control 24x7 with registration plate recognition - Automatic operation of gates and retractable posts - Schedule control - Time and client account management - Public and private car park management Automated car parking is fully automatic, centralized solution for your multi-site, multi-zone car parks, which is available 24x7 throughout the week. As we know, it is based on number plate recognition hence very easy to use. Applications - Security for public car parks,company car parks, banks, stations, administrations, etc. - Access control for hotels, clubs, camp-sites, etc - Access control for industrial suppliers and logistics - Automatic invoicing Automated Car Park Management system can also be integrated with car park management software that can handle: - Site layout - Up-to-date users file - Schedule per control point / user - Number of available parking spaces per zone - In & out flow report - Parking time / cost management - Quotas in shared car parks In this system, large parking sites can be managed by interconnecting several individual sites. All access points are then centrally managed from a centralised server. An automated car parking system comprised of a parking rack and at least one car-lifting feeder. The parking rack is divided into a plurality of parking spaces. This car-lifting feeder has a pair of comb-like wings for carrying a car into a pair of comb-like platforms, which are made on each parking space in the parking rack. Automated Car parking management allows for an error-free, fast read, non-duplicatable alternative to the traditional means of site security. With a variety of transponder form factors that can be mounted on or within the vehicle, people can enter a secured area without opening a door or a window to obtain authorization. By automated car parking management system, we can accommodate more cars in less space. This formula can be applied to almost any city in the world. This is probably the prime reasons why automated car park systems are a very attractive alternative to conventional car parking systems by making use of available space in more efficient manner.

The introduction of parking systemNew technology has made it possible to park on roads that would not have been accessible before. This will also free up more space for motor vehicles and make the parking system more efficient, thus improving the overall quality of the roads.This introduction is written by a professional copywriter with extensive experience in writing introductions for different subject areas. It is aimed at explaining how parking systems work and their advantages over other solutions available today.Section topic: There are many tools to help you write articles, but you don't need to buy them allIntroduction: There are a lot of different tools out there that can help you write better content. They can be used one-on-one or in groups or even as part of an entire team. However, we should not neglect the fact that they can alsoTips for parking systemIt is not always easy to come up with a good parking system for your company, especially when you have a lot of vehicles in your parking lot. A good parking system will require the right information about the vehicles and their owners, as well as a way to find out where they are parked.How to use parking system?Parking system is another technological advancement that has been made. The idea of parking system was first introduced in the year 1974 by a research group at MIT based at Massachusetts Institute of Technology (MIT) in the US. This system allows people to park according to their individual needs and not only on the street. Parking system has been widely used since then.The specifications of parking systemParking is a complicated issue in cities. Different parking lots are located in various places and vary in different aspects like fleet size, location and other specifics.The parking problem is also a technical one. In addition to the technical specifications, there is also an economic aspect involved into it - the market value of the parking lot to be purchased. The cost of acquiring land for a parking lot can be very high especially if it is owned by private citizens or corporations due to the need for permission from them or any other reasons that make it difficult for them to own and operate their own property.The short-term solution would be to use self-driving cars that park themselves according to certain rules while carrying out certain tasks such as loading/unloading passengers at a station or finding an available car.The product instructions of parking systemThese are instructions that are often provided in various forms and have different levels of importance. For example, some people think that the product instructions should be printed on the box or if there is a manual for the product. Others may even want to see the instructions on a website or in an app.The application of parking systemSmart parking systems are becoming more and more common. They have the ability to do many things, such as:
Is There Any Best Car Parking System Manufacturers?
Is There Any Best Car Parking System Manufacturers?
Parking hardware can be very expensive. There is something of a software revolution going on in the parking industry at the moment where disruptors are bringing cutting edge innovations which can deliver the same results for a fraction of the cost.A great example is traditionally to manage your employee parking lot you needed a gate or a barrier. The growth of software products like ParkOffice has changed the game for workplace parking. Software driven automation and optimisation is now top of the agenda. Companies can increase capacity to park staff, without increasing the number of spaces they have. Administration and capital expenditure is also rapidly decreasing as this segment moves toward a fully automated model. To solve some issues hardware is still very necessary but definitely talk to some software providers before committing to expensive capital projects.Is there any best car parking system manufacturers?1. What has been your experience with the Science Diet foods?Science Diet is one of the worst foods you can feed your dog. Read any dog food label and they want you to see meat as the first ingredient. Then look at the grain, in this case corn, and you will see things like corn, corn meal, corn gluten, etc. We know that manufacturers put the ingredient that the food has most of first, then down in descending order. After you put all the corn products together, It turns out that Science Diet is mostly corn. Dogs do not eat corn2. Why does processor speed no longer seem to matter?Processor speeds have plateaued at about 3 GHz, it does not seem economically feasible to make processors faster than that. Manufacturers are concentrating on pipelining and fast FSB to get the most out of their processors3. Changing from Ultegra 6800 crank to r8000 dual power meterActually, with respect, both above answers may be wrong. The inner chainring on the R8000 is about 0.4mm inboard of the chainring on the 6800 crankset. While the Shimano compatibility diagram is a bit hard to read, it says that technically, current generation (including R8k) front derailleurs can shift current or previous (including 6800) cranksets, but the previous generation FDs are not officially compatible with the new cranksets. To clarify: the issue is that with an R8k crankset, the 6800 FD may not move inwards enough to properly downshift and/or you could get some additional chainrub from the FD position. Shimano made the change to improve the chainline on bikes with longer chainstays and/or disc hubs. That said, 0. 4mm difference is not a lot, and that could be within the limits of adjustment. It would naturally be in Shimano's interest to sell you more stuff, so of course they would say the parts are not compatible, right? You may wish to Google this issue more. Some comments here say that there is no practical issue in mixing the relevant 6800 parts in. (Not clear if they've tried it or they just think so, and which parts they've mixed.)In the worst case, front derailleurs are not that expensive, and the new FD is definitely a significant improvement (easier to set up and adjust) than the old one, plus the new FDs are officially compatible with the old shifters (as shown on Shimano's chart).The original question did not ask, but there's a larger issue: drive-side Shimano power meters are likely to be inaccurate. This is due to the asymmetric and complex design of the drive-side crankarm. At a steady 250W, the guy in the link estimates that the drive side PMs read about 7.9% lower than a comparison pedal power meter. The issue does not appear to be something manufacturers could easily correct in software (from a conversation with an engineer on a different forum), and in any case, many manufacturers have not acknowledged it. I believe the guy in the link said that the non-drive power meters should be accurate. I also think he said that previous generation power meters should be more accurate than current generation ones, but there is still some inaccuracy there as they are slightly asymmetric. This may not seriously affect your training. However, it is a genuine issue, even though it does not appear to be widely known. If you must go dual sided, I would not rely too much on the left-right balance metrics you get, and you may want to keep in mind that your measured total power is a bit low.
Project Information on RFID Based Paid Car Parking System?
Project Information on RFID Based Paid Car Parking System?
You can check Ski Data or Omnitech website for more detailed information.For projects check - RFID based Car Parking Management System - RFID Projects1. are RFID chips being implanted into people?We live in a world where a few control the masses. This is hard to accept when you are one of the masses. It is hard to believe medications, vaccines, and baby-formulas are designed to make people week; poisoned water with florid and other chemicals; chem-trails, etc., etc... Your mind can go crazy if you know your existence on this planet is doomed. That is why people choose not to accept it, or to start panicking about it. It is very hard to accept it and remain calm. The truth is being disguised so much that is very hard to see trough all the lies we've being told over and over again. The choice is yours - whether you want to believe it, or close your eyes. But "there is no smoke without a fire". Search the internet and you will find plenty of evidence. Are you ready to hear it? What would you do if what your mother in law is saying is all true?2. What is the current state of RFID / NFC security?Most proximity card based systems use some variation of ISO 14443 to communicate between the card and the reader, but are not necessarily based on NFC. (RFID is a rather all-encompassing term, itself covering almost any use of radio waves to identify a target.) Beyond that, there has been significant evolution in what is sent across the RF. Many people think of RFID tags that send a single static number when they are interrogated, and these tags do exist -- they are often used for inventory tracking or similar functions. They are not, however, generally used for access control. Systems for access control involve challenge-response and cryptography in their operations. Even the long-broken MIFARE Classic uses cryptography, but it uses an only 48-bit key, and some weaknesses were identified that allow for ciphertext-only attacks or active attacks when talking to the reader. Since 2015, NXP has recommended new installations not use MIFARE classic.More modern systems like DESFire EV2 have not yet shown cryptographic weaknesses, but that is no guarantee of long-term strength, it's just not currently possible to clone such a card. (As you do not have the right keys to talk to the card.) Of course, if you can get your hands on a legitimate reader with the keys baked in, you can read them, but I believe NXP recommends a per-site key.Over in the HID side of things, they use a slightly different technology. HID proxcards (iClass and so forth) have actually been remarkably resilient in general. iClass was problematic because of a globally shared key -- IIRC, it was originally extracted from a reader that did not use a secure element to store the key. iClass SE rotated the key and allowed individual sites to reprogram readers to use custom keys. iClass SEOS actually runs a full JavaCard so can do a number of things with the embedded chip. At the very least, it will be able to emulate iClass SE (and I believe they've licensed DESFire EV2 and can emulate it as well).Despite all of that research, very many sites are still using HID iClass, classic Proxcard, or MIFARE Classic for access control. In the consulting world, you will see no shortage of opportunities for badge cloning3. Can I locate the object by reading its signal with RFID readers?I worked on a system that aimed to do just this using 900 MHz semi-passive RFID tags (battery powered tag silicon but purely passive communication, it gives you a lot more range since the tag does not have to harvest enough energy to power up).ToF or TDoA (Time of Flight or Time Difference of Arrival) do not work well for RFID. You can do a measurement of phase difference between transmitted and received signal and that will give you the fractional part of the wavelength in your range to the tag but solving the number of complete wavelengths is not possible with standard hardware (at least we could not find a solution). Our solution was to take a series of readings along one side of the field (it took about 10). The readings were not all taken from the same height above the ground. We then took the RSSI numbers from the readings and from that calculated the tag location and height. We were taking readings sequentially from the same receiver that was moving but there is no reason why you could not use a set of fixed readers.The calculations ended up being non-trivial. You have the standard inverse square law for the signal strength but you also need to factor in the ground bounce, that will depend on antenna heights, frequency and ground material. You get both direct and ground path signals in both directions giving a total of 4 different signal paths that are interfering with each other. You then also have to factor in tag and receiver gain patterns.However once you have a good enough model you can create a probability map of where in the field the tag is likely to be based on the observed signals. It was taking matlab about 20 minutes to crunch the numbers on a 10 year old PC. I managed to get the end results to normally be within 20-30 cm of truth at ranges of up to 40 m.When it worked we managed to get this down to around 5 cm error by factoring in the partial phase information of the returned signal but that was unreliable at times.The killer problem ended up being that as soon as you added any RF absorbing/reflecting objects into the environment (e.g. people, animals or anything made of metal) then the whole system fell apart.For the sort of problem you are describing I would normally say to go with a UWB based TDoA based system. That will give you 10-50 cm accuracy depending on how well the system is dialed in with low latency and be fairly immune to environmental changes if base station antennas are mounted high enough. While not as cheap as an RFID tag you can make the tags in the $25 range and run them off a watch battery of a year or more.
Describe the Automatic Car Parking System?
Describe the Automatic Car Parking System?
Well, if you are talking about the Lexus LS parking sustem that was just released in the U.S. then here goes... The car is equipped with a navigation and rear camera system so, when you put the car in reverse it brings up the rearview camera on the NAV screen. Then the driver highlights the parking spot with a cursor on the screen and the car then has sensors on the front and rear bumpers that let the computer know where the curb and other cars are. The only things the driver does during the parking sequence is put the car in reverse/drive and they have to have their foot on the brake to control the speed at which the car moves. The car will turn the steering wheel on its own.1. Why is the parking in Houston so bad?The land is so expensive in those areas and nobody wants to buy land to put parking spaces on it. However, YOU see the problem and might be able to remedy it. Buy some land and create a paid parking lot. The land would make money for you. Not as much as a store would make if you built on the land, or if you subdivided the land and built on it, but still money. Oh dear! THAT is the problem. People had rather squeeze as many buildings in the space as possible. They leave the parking dilemma for the patrons to deal with.2. Motorcycle Parking in Bricktown - Oklahoma City, OK?just park it where there are no signs3. Issues with my landlord and parking spaces?I know parking in some places can be a bear... I am in Long Beach and it's the same. But the thing is, if parking was important to you, you should have figured it out before you signed a lease. Now your option is to find somewhere else to park, try to get it in the lease when it renews, or move...4. "Illegal" parking on school grounds?It's not illegal and it not considered vandalism since its placed on the window to wit it can be removed with some work just not easily thus the whole purpose of the notice it actually a common used tool to keep people from parking in certain areas they are not authorized to park in5. Why do cities never seem to have enough parking? Is it hard to create more usable spaces for parking?I disagree with claims made of insufficient parking spaces,here in Chicago city has specific requirements and that creates enought parking spaces.If questions are that it costs more in terms rental,that is justified and correct6. Could I quikrete a parking lot?They will be able to advise what type of concrete is best suited for this purpose as well as give you an estimate of the cost of the concrete. Some companies may also be able to do the installation and finishing. Read the following: ============================================== Selecting contractors: 1/ Look up local contractors first. work out from the closest to your location. If someone you trust has had work done similar to yours, ask them about the contractor they used. If they were completely satisfied with their contractor(s), ask for their telephone number. 2/ Select at least 5 your are interested 3/ Do a google/yahoo search on each of the contractors you are interested in; look for praises (check who is writing the praises to see if they have any connection to the contractor google/yahoo search the people giving the praise or references) 4/ When you are satisfied with at least 3 contractors per job, have them give you written estimates with details of work to be done, terms, guarantee(s), cost of extras (how much do they charge if they find something not covered by the contract), paymant schedules if necessary and whatever else you can think of to protect yourself. 5/ If the contractor tries to pressure you into signing the contract immediately with a high deposit (more than 15% - deposits over 10% normally are not paid untill material is delivered and left at your site) reject that contractor. Be careful, high pressure can be someone who sounds very convincing, but has many reasons why you should sign on the dotted line NOW. 6/ It is always good to have another adult with you when a contractor inspects the work to be done. 7/ If you do not get at least 3 written estimates signed by the contractor - not you (do not sign yet) , go back to 1. repeat until you get written estimates signed by the contractor - not you (do not sign yet). Read the estimates over with some who has some knowledge of the work that has to be done. This may take longer than you thought; do not rush into it. Research, resaerch research, helps. When you are ready choose by being informed. Good Luck
