Development advisory and owner-side project management for owners and small developers in Ottawa.
Lumenalis Consulting Ltd. provides feasibility analysis, financial modelling, project controls, and owner’s representation to clients who need experienced development capability on a defined assignment, without keeping a full in-house team.

Principal
Mohamed Abdelrahman incorporated Lumenalis Consulting Ltd. in September 2023, after working in construction and development project management in Ottawa since 2021.
That record now exceeds fifty projects across owner-developer builds and conversions, infill, institutional and commercial fit-ups, and private residential construction. The nineteen projects documented under Selected Works carry an aggregate value of about $30.5 million, of which about $17.3 million is construction value he managed directly.
Alongside the project work he builds the budgets, cost-control systems, and reporting on which development and construction depend, so that an owner can see where a project stands at any moment.
Lumenalis makes that owner-side capability, the feasibility, financial, and project leadership that larger developers keep in-house, available to small developers and owners on a project-specific basis.

Operating principles
Test the major assumptions before committing capital.
The cost of changing direction rises as the owner commits to design, financing, procurement, and construction, so early work concentrates on the assumptions capable of changing the project decision, before anyone spends the capital that depends on them.
Scope every engagement in writing.
Lumenalis quotes defined assignments as a fixed fee against a written scope that states its exclusions; hourly advisory and percentage-of-cost construction-management mandates are available where the work suits them, and a written change adds anything outside the agreed scope.
Date, version, and keep the record.
Each deliverable carries a document control number, a version, and a date, and Lumenalis records material decisions and changes as the project runs, so that anyone can trace the basis of the current budget, schedule, and scope.
Independence is the product.
Lumenalis works for the owner, and the owner pays the fee. The firm holds no interest in any contractor, brokerage, or lender it recommends or supervises, and no fee depends on a transaction closing.
The standard of the work
A reader can recompute every figure Lumenalis publishes from its stated basis, because the firm builds its pro formas, cost plans, and feasibility models for the reader to open and test.
Lumenalis classifies cost estimates against the AACE International 56R-08 framework, follows CMHC underwriting conventions in insured-financing work, and anonymises the sample models under Selected Works to PIPEDA standards with their arithmetic intact.
The firm reviews its own work adversarially before it leaves the practice, so the first reader to attack a model is the one that built it, and what an owner receives has already met the questions a lender will ask.
Where Lumenalis works, and with whom
Lumenalis works from Ottawa, in person across the city and the Ottawa-Gatineau region; it supports selected assignments elsewhere in Eastern Ontario and the broader Ontario market remotely and arranges site attendance where the work requires it. Typical clients are small developers, property owners, private investors, and owner-builders, on assignments below $10 million in project value, and the practice takes a limited number of engagements at a time.

Common questions
How are fees structured?
Lumenalis quotes defined assignments as a fixed fee against a written scope, deliverables, assumptions, and exclusions; it bills hourly advisory and percentage-of-cost construction-management mandates where they suit the work, and anything outside the agreed scope goes into a written change before the work starts.
What size and stage of project does Lumenalis take?
Small developers, owners, private investors, and owner-builders, typically on residential development, renovations, conversions, infill, and acquisitions below $10 million in project value. An engagement can cover one stage, such as a feasibility study or an independent review of a project already underway, or continue through several.
Does Lumenalis arrange financing or deal with CMHC directly?
No. Lumenalis prepares and coordinates the owner-side package; the licensed mortgage broker or approved lender submits it and holds the relationship with the insurer. The firm provides no mortgage brokerage, securities, legal, accounting, or professional-engineering services.
