Monument construction is probably the single most extensive
activities in the game, so I've compiled (and will continue to update)
the following list.
Employement: Make sure your guilds and work camps
are fully staffed. If either of these are short on labor, it will
affect how fast your monument is built.
Materials: Check your supply of building materials. Sometimes
trade conditions will change during a game, which can change how much
you're allowed to import each year. If you are providing your own
building materials, make sure your industries are fully staffed. Wood
is crucial to most monuments - so always make sure your carpenters
have enough. Without wooden ramps/scaffolding to facilitae the workers
and materials, construction will cease.
Storage: Make sure you've got some yards to store the construction
materials! Laborers haul 400 units of construction materials at a
time. If you have 300 units (or 3 blocks) in one storage yard and
100 units (or 1 block) in another, the laborers won't touch them.
You can use the get/empty functions of your storage yard's special
orders screen to consolidate goods.
Stockpiling: Make sure you're not stockpiling the materials
you need to build the monument. If you are (check your Overseer of
Commerce screen), it puts a freeze on the material(s) in question,
stopping construction completely.
Proximity: Keeping your storage yards, work camps, guilds,
and construction site as close together as possible. Reducing distances
reduces travel time, which will speed up construction. Build the necessary
structures right across the street from your monument site if you
can!
Season: If you have floodplain farms in the particular mission
you are playing, the season will affect your monument. Laborers from
work camps are diverted from construction to tend the floodplain farms
during harvest time. This pause in construction can be offset somewhat
by providing more (fully staffed) work camps.
Access: Make sure all the guilds, work camps, and storage
yards roads access. The construction site does not need to be connected
to a road, but there must be a path (unobstructed by buildings or
terrain) from the road to the monument.
Grave Goods: Some monuments require burial gifts. If construction
seems complete, but you haven't reached your monument rating, check
your Overseer of Monuments screen to see if you need to dispatch some
grave goods.
That covers most basic problems with monument construction.
If none of the above applies, but construction on your monument has
still ceased, here are some workarounds you can try:
Deleting and undoing: Try deleting (then immediately select
'undo' so they reappear) your guilds, work camps, or even the monument
itself. Some players have found that this 'jumpstarts' construction.
Causeway: Some players have reported encountering a problem
with the causeway in their pyramid complexes. Specifically, the section
where the causeway meets the water is not being completed. In this
case, placing gardens on the tiles from the end of the causeway to
the water should continue construction.

tips and updates. Hope this helps!
