The Distinctive ‘Floating’ Roof of Jasper Place Library

use of post-tensioning in the trough regions to control deformations. However, it was not until a satisfactory construction procedure was proposed, accompanied by detailed costing, that these fears were adequately allayed and the go-ahead for final design and construction was given. The project achieved economy of design by incorporating flat surfaces between the peaks and valleys. It was also proposed to pour the flatter slopes, including the valleys, without top forms prior to pouring the steeper sloped roof and peak portions. This simplified the formwork and enabled pouring of the sloped roof surfaces without excessive wet concrete pressures in the trough regions. With the digitalization of reading material becoming more popular, the City of Edmonton wanted to create a space that would house tangible reading material, and more importantly serve as a social space for the community. The final design features an open space devoid of columns and allows for the opportunity of maximum social potential in the coming years. Targeting LEED Silver, the striking architectural form and ample daylight of Jasper Place Library has resulted in a happy and sustainable space for users. Favorable feedback from both the Client and the public has testified to the value of creative design.▪ Derek Ratzlaff, P.Eng, contributes a strong knowledge of wood frame construction to his work as a structural engineer. He was appointed an Associate in 2013, assuming a primary role as mentor for Fast + Epp’s young engineers and fostering professional development within the firm. Derek has acted as Project Engineer for numerous challenging projects, with a particular focus on those utilizing hybrid wood-steel and wood-concrete combinations on a large scale.

President’s Message Moving Up Requires Effort

Barry Arnold, P.E., S.E., SECB, NCSEA Board President Great leaders have six characteristics in common: an insatiable curiosity – they are always looking to enhance their current level of knowledge and performance; a willingness to learn – they want to complement their current understanding with new ideas and material; a willingness to seek expert advice – they seek mentors and coaches with proven credentials to guide them toward higher efficiency, accuracy, and monetary rewards; they associate with people who have similar problems and diverse views – they want to be found among peers that want to be successful and have found ways to overcome their problems; they know that in an ever-changing world success can be fleeting – they know they must continually spend the time and effort to consistently be on top; and they know that time is precious – they want to invest every minute in opportunities that will produce the greatest rate of return.

All the great leaders embrace these six concepts with passion. That is true of the great leaders in politics, sports, science, and business. They know that true success is not inherited but earned through personal sacrifice, continual education, and determination. They know that to be truly successful they must invest continuously in improving themselves and their company. There is no ‘Easy Button’ for true and lasting success. There never has been and never will be. Much fantasy literature has been written about the self-made man – the person who comes from nowhere and with nothing and somehow they miraculously and against all odds achieve great success. It’s the stuff of legends and dreams. The problem is that it didn’t happen that way – ever. Those that achieve great success follow the rules of success – all six concepts. The myth of the self-made man is a primary cause of many business failures. People think starting and running a business will be easy and jump in with wild expectations and dreams of riches and respect, without understanding the amount of work and knowledge involved. Success takes personal effort and dedication, combined with a life-long commitment to pursue knowledge. Operating and building a business can, to paraphrase Charles Dickens, “be the best of times, it can be the worst of times, it can be the age of wisdom, it can be the age of foolishness…” The outcome of any business venture is irrevocably linked to the effort put into learning and managing the business from sources that respect your time and maximize your ROI by providing valuable, relevant, and current information you can use. There is no greater challenge than running a successful business, and there is no greater reward than having run it well. NCSEA wants to assist you on the road to success by providing an opportunity to attend the Winter Leadership Forum. Whether you’re just starting out and wondering where to begin; or if you dealing with growth, client, or employee problems; or if you’re getting to the age where you want to retire and want to sell your business, NCSEA wants to assist you in finding the best answers to the questions you have. The WLF provides ample opportunity to mingle with your peers, to share experiences and ideas that will strengthen your place in the market. It’s the place to be to compare notes and openly and safely share successes and failures and receive advice. It’s the place where great leaders come to hone their business acumen and plan for the future. For the past two years, the WLF has been the place where those that were serious about their careers and businesses met to discuss current trends. It’s been the place for those with insatiable curiosity, for those with a willingness to learn and share experiences, and for those open to seeking expert advice and the advice of peers. Those that attend want to be and stay successful. They know that they must expend time and effort to consistently be on top, and they know that time is precious and they want to invest in opportunities that will produce the greatest rate of return. The WLF is the place where great leaders gather. At the WLF you won’t find just a single answer to a problem, you will find lots of answers, a variety of diverse viewpoints from leaders who know the ropes. You will not find any fluff at the WLF – just practical solutions to the problems you face. The WLF isn’t a vacation. It is an opportunity for you to invest in yourself and in your company. NCSEA is dedicated to helping seasoned and novice business owners obtain and share the knowledge and skill to navigate the complicated business environment. The 2015 Winter Leadership Forum will be held in Coral Gables, Florida on January 29-30. Register online at: www.ncsea.com/meetings/winterleadershipforum/.

Strengthen your Competitive Edge

Increase your Decision-Making Skills

Does your company have data but lack insight? Is the rapid pace of change a challenge to timely decision-making? Is valuable time wasted searching for just one more piece of data? As a leader of a small firm, you face increasingly complex decisions–decisions that are filled with ambiguity, uncertainty and risk. To remain competitive, you can’t wait for complete data and certainty. To save time and money, you must decide and decide now. It’s easy. Successful leaders know the secret. They gather as much information as feasible and they pay attention to intuition – gut feel. Powerful decisions come from balancing cognition and intuition in a skilled internal calculus. New research in neuroscience reveals the proven processes your brain uses to perform that calculus. Now you can harness that power for the management of your firm and development of future leaders. Through these sessions, discover practical skills that put neuroscience to work for you and your business so that you can avoid the pitfalls of over-thinking; sidestep analysis paralysis; learn techniques to simplify complex decisions; and develop future leaders who are both smart and insightful. Increase your decision-making skills now at ACEC’s Small Firm Council’s (SFC) annual Winter Meeting, February 20-21 in Nashville. Speaker, Coach and Author, Shelley Row, P.E., of Shelley Row Associates LLC will ignite an interactive exploration of complex decision-making based on her personal interviews with over 70 leaders. The data confirms that the most effective leaders make decisions by gathering information while trusting their intuition. That remarkable combination is what Shelley calls infotuition™. Don’t over-think it! Join the discussion today. Infotuition™…You’ve got it. Are you using it? To register, visit www.acec.org/coalitions.
