Roof Mounted, Building Access Equipment

Montreal, Quebec, Canada

Mike was co-owner and General Manager of J.O.Dougall Ltd., the equipment designer and manufacturer.

This project included the Design, Manufacture and installation of the roof mounted Access Equipment. It was purchased for the building exterior maintenance and window washing

Special Design Features:

• Linked four drum personnel hoist designed for personnel use
• PLC controlled, limit switches,CWT coordinated to move in conjunction withposition of access stage. Thereby providing a balanced cantilever condition that allowed the system weight to be minimized
• Use of sectional stage system, seesectional staging
• Complex building geometry,PLC coordinated descent and ascent controls for the personnel

Railway Safety Fall Arrest Equipment

Mike was President Of Smmart Equipment Inc, the equipment developer and manufacturer.

This line of safety products was developed to satisfy the USA, Federal Railway Association regulations, Part 214 ‘Bridge worker Safety Rules’.

Special Design Features:

• 3 USA Utility Patents awarded
• Software developed for user configuration set up
• Research carried out to determine forces on worker resulting from impact of fall. This researchprovided the guidelines for understanding how to bestprotect the worker
• Many features of the research and technology were adopted by the OntarioMinistry of Labour, for its regulations developed for fall arrest systems used for construction workers on structural steel buildings

Modular Access Equipment, Sectional Staging

Mike was co-owner and General Manager of J.O.Dougall Ltd., the equipment designer and manufacturer.

This project included the Design and Development of a Modular Staging Systemfor use in maintaining the exterior of buildings

Special Design Features:

• Best Strength per Weight Ratio of any Staging system available at the time
• This system was assembled using tension rivets in conjunction with specially designed aluminum extrusions
• Prior to this design, sectional stages were mostly constructed using aluminum materials that were connected by welding. Since aluminum that is welded introduces many weaknesses in the parent materials, there was a need to use 40% extra parent material to compensate. Welded sectional stages experience brittle failures resulting in worker injuries.As can be seen in the test picture, the staging system developed on this project provides a superior ductile mechanism.
  

Launching Gantry Old Saybrook, CT, USA Baldwin Bridge Construction

Mike was co-owner and General Manager of J.O.Dougall Ltd., the equipment designer and manufacturer.

This project included the Design and Development of Launching Gantry Equipment that set up to 11 segments per day. When the contractor bid the project they intended to set 2 segments per day using a scow and head frame hoists. The design and supply of this equipment reduced the construction schedule by more than 1 year

Special Design Features:

• 420 foot long Launching Gantry, 550 tons
• Hydraulically operated control system
• Largest segments were 400 kips

Skydome Stadium Toronto, Ontario, Canada

Mike was a project manager for the Design/Build contractor Ellis Don. Responsibilities were the coordination of design and construction of the retractable roof and movable stands.

This project included the Design and Construction of the steel structures, roof and movable seating bogies, control systems, envelope & roof seals.

• Movable Roof structure weighs 9,600 tons
• Development of passive seal system to reduce failure occurrences experienced in previously built retractable roofs with mechanical sealing systems
• Roof opens in 20 minutes and is operated from a single control room
  

Ellis-Don / Tobishima Joint Venture, Japan

Working in Japan Mike played a role with the design and construction team responsible for the development of retractable roof designand construction procedures.

Special Design features:

• Alternate retractable roof stadium sizes designed to suit construction of stadia at numerous locations throughout Japan
