Concept Design : At the concept design stage,
we work with Architects to review the concept design brief,
collect building population data, study the men/material
movement within the building and prepare an estimate of average
intervals and average waiting times. We establish and recommend
design criteria based on international design standards and best
practices and recommend the best suited elevator/escalator group
configuration for each traffic type. We provide
elevator/escalator/dumbwaiter core dimensions and indicate
relevant structural support requirements. We provide a concept
design report detailing our study, the design approach, the
design criteria, traffic analysis results and the selected
elevator group configuration. We also provide preliminary ideas
on accessibility, firefighting elevator and service elevator.
Schematic Design : This is optional and
applicable only if the concept design is completely changed.
Activities are very similar to Concept Design. We attend design
meetings, authority meetings and Client presentations as
required.
Detailed Design : Based on the final
elevator/escalator group configuration, we provide elaborate
design details for the equipment, machinery spaces and control
spaces. We define clearances, access conditions, structural
load, mechanical coordination details, electrical coordination
details, plumbing coordination details, interior design
coordination details and carry out other specialty
equipment/features coordination.
Tender Documents : We provide
performance specifications in CSI format: CSI specifications X10, 14210, 142100 (elevators-lifts)
X11, 14310, 143100 (escalators). We review the pre-qualifications of vendors and provide approved
list of vendors, specific for the project.
We review if all the agreed design coordination and
requirements are incorporated within the specifications.
Alternatively, we can peer-review the specifications prepared by
the Architects and provide comments for improvement. Where
required, we review the vertical transportation design drawings
prepared by the Architects for compliance with the elected
vertical transportation design.
Main Tender Evaluation : We
participate in the tendering process for the main works. We review
and provide responses to the Tenderer’s queries related to
vertical transportation promptly. Where required, we participate in
the tender evaluation of main contractors and address issues related
to vertical transportation.
Construction Documents : This is optional and
applicable only if the tender specifications are completely
changed at the time of awarding the main contract [due to value
engineering or for any other reason].
Vertical Transportation Contractors’ Tender
Review and Selection : We review and provide
responses to the vertical transportation contractor’s
queries promptly. We provide our technical assistance to review
specific vertical transportation contractors’ technical
and commercial bids. We thoroughly review the bids and provide
deviation list and compliance requirements in comparison with
the construction document specifications/drawings. We provide a
technical comparison and a cost comparison of the elevator
contractors. We conduct tender negotiation meetings with the
vertical transportation contractors and make recommendations for
timely award of the project and to achieve full/maximum
compliance to the construction documents.
Construction Supervision : Once the Elevator
Contract is awarded, we supervise the vertical transportation
contractor’s complete scope of work to comply with the
construction documents and agreements.
Desktop review of technical submittals and
drawings : We review the technical submittals related
to the elevator/escalator/dumbwaiter equipment [machine, controller,
doors, fire & life safety equipment] and recommend their full
compliance to construction specifications and governing equipment
codes and accessibility standards. We also provide valuable inputs
and recommendations for the interior decoration of the elevator cars
and entrances, escalator truss cladding in coordination with the
interior design Architect. We make coordination comments for the
vertical transportation equipment with other engineering disciplines
so that the vertical transportation systems work in tandem with
other engineering features/equipment of the project. We also review
quality control forms of installation data recorded on site,
Operating & Maintenance Manuals, Warranty certificates and
handover certificates.
On-site coordination meetings: We attend technical coordination
and progress meetings arranged by the Architect on site. We
review technical queries, construction difficulties and
coordination issues at the meeting raised by the vertical
transportation contractor and the main contractor. We provide
technical guidance, we participate in site-walks with the
construction supervision team on site and provide valuable
inputs and clarify any query from the project’s Owners and
stake holders.
On-site progress inspections : Upon specific
request, we conduct progress installation inspections on site
and review the status of installation of work and quality of
installation. We inspect elevator entrances, inside of elevator
shaft, elevator machine rooms, escalators, dumbwaiters and
provide technical comments on deviations and provide guidance
for improvement.
On-site material inspections : When required,
we conduct material inspections on the materials
destined/delivered for the project. We visit elevator/escalator
contractor’s factories and/or interior decoration
workshops; we review the material quality, specifications, test
data and as-installed condition of the elevator equipment. We
provide technical comments and recommend improvement of
equipment quality and the interior finishes.
On-site performance inspections : At the time
of handing over, we conduct performance specifications on fully
completed elevators and escalators. We review the acceleration,
jerk, door times and velocity profiles of each elevator and
encourage conformance to original elevator traffic design. We
verify the performance parameters, safety features and special
functional controls against the construction specification and
produce item-by-item specification compliance list. Deviations,
if any, are highlighted and issued as a snags list. We carry out
follow up inspections [when required] to verify if the
previously noted snags have been cleared or not.
Modernization Consulting : We provide
population surveys to assess waiting time/interval standards on
existing buildings and provide recommendations to improve the
performance of existing elevator/escalator systems. We survey
existing equipment on for their condition and provide
recommendations on expected life time,
renewal/repair/replacement requirements, equipment upgrade to
comply with latest equipment safety standards. Based on
Client’s approval, we develop modernization tender
specifications [both main equipment and interior finishes]
conduct the modernization tendering process with pre-approved
elevator contractors.
We provide our technical assistance to review specific
elevator/escalator contractors’ technical and commercial
bids. We thoroughly review the bids and provide deviation list
and compliance requirements in comparison with the modernization
specifications. We provide technical comparison and cost
comparison and we conduct tender negotiation meetings with the
Elevator/Escalator Contractors. We make final recommendations
for timely award of the project and to achieve full/maximum
compliance to the construction documents.
Construction Supervision : Once the
Modernization Contract is awarded, we supervise the elevator
contractor’s complete scope of work until completion to
comply with the construction documents and agreements. Desk top
reviews, onsite meetings and inspections are provided as deemed
necessary.
Portfolio Management Consulting : For single
building Owners and/or real estate companies, we provide
technical assistance to manage their portfolio of vertical
transportation equipment. We review the existing maintenance
contract clauses, the qualifications of elevator maintenance
companies and make recommendations on compliance to local
regulation requirements with safe working conditions to the
users and the elevator maintenance personnel. We survey existing
equipment for their condition and provide recommendations on
expected life time, renewal/repair/replacement requirements,
equipment upgrade to comply with latest equipment safety
standards.
