From electronic books to an ingenious hand-held projector, Kristina Smith discovers the devices you simply cannot live without

1. Optoma Pico projector

鈥楾his is a quick-fix presentation gadget. We can access all our drawings and files on our laptops wherever we are. But if you have got more than two people sitting round a laptop, often you can鈥檛 see what you are looking at. This gadget allows you to expand the drawings as a projection onto a wall. It鈥檚 only the size of a cigarette packet, so it鈥檚 handy to carry around because it鈥檚 so light.鈥

Chris Chivers, managing director, Killby & Gayford.

2. BlackBerry Curve

鈥楾his is brilliant 鈥 it鈥檚 robust, it never crashes and it makes me more efficient. I am in charge of strategy with my executive board colleagues and then responsible for implementing that with our top customers.

I probably spend two-thirds of my time out with customers. Having the BlackBerry means that between meetings I can clear all my emails and keep up to date with where the market is going, where deals are going, what鈥檚 happening with customers. I have developed a knack for high-speed typing even though I have chubby little fingers. My colleagues are amazed at how fast I can type. I got hooked on Nokia predictive texting in early 2000 and never looked back!鈥

Stephen Wells, business strategy and development director, Costain.

3. MacBook Pro

鈥業 do everything on my Mac, I am online all the time. Recently I have been using it to Tweet. We went live with the Mace Group Twitter account at the end of April (Twitter.com/macegroup). We are using it as a feed, trying to encourage traffic back to the website. It鈥檚 very important that it鈥檚 a live feed. If you ignore it for five days, you lose audience. Also, through Tweetdeck [a browser that lets you follow several Twitterers at once] you can very quickly and easily see any comments about your company. If you are in the mix you can catch that and respond in a positive way to any criticism, although we haven鈥檛 had any yet.鈥

4. BlackBerry Pearl

鈥楢 lot of people say to me 鈥測ou never forget anything鈥.

It鈥檚 because I dictate notes and prompts using my BlackBerry. A fair bit of my time is spent out on site, with technicians in their vans, or in local offices. It鈥檚 not always appropriate to have a laptop or pen and paper 鈥 for example if you鈥檙e halfway up a scaffold. And if you are in your suit with a pad and paper, it can be a bit formal and cause people to clam up. With this, they don鈥檛 feel like they are being watched or monitored. I make notes of good or bad practice, ideas and things I want to do when I get back to the office.鈥

Shaun Davis, director of safety, health, environment and quality, Rok.

5. HTC-TyTN II

鈥業t鈥檚 a phone, a camera, a mini laptop. It does emails, my diary, stores all my contacts, has an internet browser (great for cheating at pub quizzes). It鈥檚 a calculator, it鈥檚 got games on to keep my kids amused, it even has a GPS receiver so it鈥檚 also got TomTom Sat Nav. It鈥檚 the Swiss Army Knife of the electronic gadget world! I bought it about a year ago. For once in my life I wanted something that was absolutely at the top of the market and wouldn鈥檛 go out of date so quick. Now the company is buying it for the senior guys.鈥

Neil Bradley, head of pre-construction and design, Thomas Vale.

6. Merlin Lazer

鈥業 first came across the Merlin Lazer some 10 years ago when I had to survey a tall building with neither safe external access nor any opening windows. It鈥檚 a device for measuring the thickness of double-glazed units from one side of the glass. It's really useful because it鈥檚 small and light and easy to slip into a computer bag. There are alternatives available, but I have found they have a limited lifespan and are not as accurate.

We have other pieces of kit, for example to check coatings on glass to see whether it is toughened and torque gauges to check doors for DDA compliance, but this one remains my favourite.鈥

Steve Bosi, technical director of facade engineering, WSP Group

7. SmartBoard

鈥楢t weekly planning meetings our team and our subcontractors agree the plan for the following week. The team use the SmartTech SmartBoard to call up the site drawings from a laptop, and then you can use electronic pens that come with the system to mark comments or revisions on the projected drawings. For instance, we mark up who will be working where in the following week, where materials will be placed and how they will be distributed. The marked-up drawings are printed off after the meeting and everyone is given a copy.

8. Sony Reader eBook

鈥業 have had this for three months, and although I鈥檝e only downloaded novels so far I can see it really making a difference professionally. I鈥檓 a town planner and it would be really handy to carry round planning law guides and other technical books on it.

It鈥檚 about the size of a small paperback, with a white screen with black writing. You turn the pages by pressing a button. You download whatever books you want just like you download music.

It can hold about 100 books and has a full indexing system. If I am going away on business I used to always take a couple of books. Now I just download what I want and pop my Reader into my briefcase.鈥

Phil Cusak, director, AECOM Medion.

9. GoPal Sat Nav

鈥楾his is so fantastic. It鈥檚 really easy to do your mileage claim form for your expenses, you just put in your start point and end point. If I鈥檓 on a construction site somewhere in the middle of nowhere I can call my kids up and say I鈥檒l pick you up outside Debenhams at 4:52 and it鈥檚 always right within a couple of minutes. Likewise, when I am travelling round the country I can let people know if I am going to be 10 minutes later, or quarter of an hour. It seems very accurate, so it鈥檚 good for expectation management. I bought it from Sainsbury鈥檚 for about 拢90 I think and it is worth every penny.鈥

Charles Tinknall, head of process improvement, Willmott Dixon.

10. Huawei E160

鈥楾he intuitive simplicity of my Huawei E160 USB dongle [modem] is a godsend when I cannot reach a Kier networked docking station and Wi-Fi is unobtainable. Travelling to BSF projects from Cumbria to Kent and an assortment of laboratories, hotels, offices and colleges in between, this is a frequent occurrence! Its 鈥減lug and play鈥 3.6Mbps connection speed, plus USB cable to improve signal reception 鈥渨eb enables鈥 me for email, text and phonebook, even in remote areas. So, what looks like nothing more than a cheap throwaway cigarette lighter is actually 84mm of pure technological genius.鈥
